Abstract

The present invention relates to colorful anti-rust iron and steel without paint, which belongs to the technical field of the smelting and milling of metallurgy iron and steel enterprises. The colorful anti-rust iron and steel are the pig iron and steel which have strong oxidation resistance, corrosion prevention and no rust. The ingredient structure and the rust preventing effect are same as those of stainless steel, and the colors of the varieties are different. The color of each variety is the permanent colorful color which is consistent from inside to outside. The present invention aims to firstly solve the key problem of iron corrosion for changing the structure of the ingredients of the pig iron. The smelting mode that the hardware technology of smelting the iron, smelting the steel and rolling the steel is not changed, no hardware investment is required, the combination of a soft technology and a hard technology is used, an iron smelting factory is used as the first position, and the operation of smelting the steel and the operation of rolling the steel are followed. The smelting mode that a plurality of non-ferrous materials are added to smelted stainless steel is changed into a new technology that a plurality of non-ferrous metal ores are matched with iron ores when the iron is smelted and the anti-rust colorful pig iron is smelted in a one-time mode by a blast furnace in order to smelt the steel and roll bars. Thus, the purposes that the iron and the steel do not have rust and are colorful are obtained, and the difficult problems of alleviating the rust corrosion and treating the root cause of the rust corrosion of the iron and the steel are thoroughly solved.

Description

Antirust colored steel alloy

One, denomination of invention: antirust colored steel alloy.

Two, technical field: the smelting rolling technical field of affiliated iron and steel metallurgy enterprise.

Three, background technology: known metallurgy has ferrous metallurgy and nonferrous metallurgy two major types, and ferrous metallurgy is that iron and steel, nonferrous metallurgy are nonferrous materialss, all smelts out respectively with various native metals ore deposit.Iron and steel is the common name of the various steel and the pig iron, should be the iron steel in order, ironworks, Hanyang, the recent company of Nippon Steel of Japan as old China, be exactly that the meaning that steel is arranged behind the iron is arranged earlier, steel is that the pig iron is smelt, there is not its steel of iron to come from what? therefore, this paper is placed on iron the front of steel, mainly be to say the corrosion problem that solves the pig iron and steel, so be the iron steel.But, the kind of the pig iron is few, purposes is wideless, the pig iron that blast-furnace smelting comes out has only two kinds: the one, and mouthful iron certainly of steel-making usefulness, the 2nd, the casting usefulness graphitic pig iron, and ironmaking main purpose be used for steel-making, so, people are commonly referred to as iron and steel again habitually, and enterprise such or such Iron And Steel Company by name is a lot.Natural iron ore is a basic raw material of smelting the pig iron, coke is a main fuel, Wingdale and rhombspar etc. are auxiliary materials, these are former, blast furnace is imported in combustion, material in batches successively, the high speed strong wind that gas blower bloats, through the continuous Gao Baishi hotblast stove of too much seat, cold wind is preheating to about 1000 ℃, light again wind conveying pipe road blows into the combustion-supporting coke of blast furnace and produces large volume of fire, its high temperature is red as fire liquid with the fusing of solid lump ore, slag is put slag trough into from slag notch and is poured the Sheng slag bath through the strong cooling of high pressure water, just becomes the cement raw material of I grain; Molten iron has been filled cupola well and has just been put the molten iron steamed stuffed bun into from iron notch and draw steel-making, or the casting ironware, or waters and be iron block.At present, blast furnace both domestic and external is still this technology and smelts the pig iron, also finds no institute and changes, and multiple metallic ore more of no use closes the precedent of refining heterogeneous alloy.The pig iron is the basic raw material of steel-making, lime, fluorite, ferric oxide etc. are the auxiliary materials of slag making, coal gas, Sweet natural gas, oxygen are the geseous fuel of steel-making, after being eliminated, openhearth steelmaking over a long time changes converter steelmaking into, next is the electrosmelting special steel, all steel capital are to smelt like this, not have new side.Three developmental stage have been experienced in the industry of iron steel, and the fs is before the World War I in 1914; Subordinate phase is to the World War II of nineteen thirty-nine after the World War I; Phase III be World War II so far.Before Two World Wars mainly be to break iron and steel, many countries have drawn bitter lesson in two wars, understood a truth, have iron and steel can beat others or keep out others attack, do not have iron and steel just only to get a beating! As the saying goes, unarmed, one pair of phase of getting a beating exactly, old China has only ironworks, a Hanyang, and Iron And Steel Industry is extremely undeveloped, all is to get a beating to phase in all previous war.After the World War II, many countries are all greatly developing the industry of iron steel, founding of New five during the last ten years, output of steel leaps to the first in the world, reached 8.43 hundred million tons to whole world output of steel in 2000, the maximum front three of product steel is: 1.26 hundred million tons in China, 1.06 hundred million tons in Japan, 1.01 hundred million tons in the U.S..Calendar year 2001, Chinese output of steel reached 1.5 hundred million tons.The steel of the world today produces how and more, and still, an iron steel familial inheritance obstinate disease so far---rust cancer is still controlled badly, makes us very worried!

Four, summary of the invention: technical problem to be solved solves the technical scheme that its technical problem adopts, beneficial effect against existing technologies:

(1) technical problem to be solved: human society will advance, just needs better, and more iron steel, still, there is a very big disadvantage in the iron steel---a rust! Be born so far all at rust from it! A rust! A rust! A rust! Rust has been lacked its life-span! A tremendous loss of having become rusty! Become rusty one to produce and coated with lacquer, sell lacquer, mopping, zinc-plated, chromed huge troop is its service for a long time, the mopping that goes round and begins again, rust cleaning, mopping again, eternal vicious cycle operation no matter how high your skill is, is coated with lacquer well again, plate firmly again, how long also be unable to control or manage, get rusty as before behind the surface peeling.Military various firearms will get rusty equally, barral of a gun, gun tube inwall get rusty can not paint, zinc-plated, chromium plating, only make good use of the frequent wiping of cotton and silk, especially various gun tubes be difficult to be wiped, be with special special-purpose poles, and the push-and-pull of several soldiers' ability must be moved, it is just qualified to polish, the wiping firearms have not only become the heavy burden of all armies in the world, and will consume great amount of manpower and material resources, financial resources.The iron steel has become rusty several thousand also at rust! Become rusty to such an extent that human generation generation puzzles one's brains from generation to generation, everybody sees that rust is vexed, is coated with the old way of wet goods from the polishing wiping, to brush paint, zinc-plated, plate chromium, spray paint, the modern crafts of plastic-blasting, also control bad its rust.As the saying goes that reading is not easy, a word value a thousand pieces of gold.What the ratio reading was more difficult is: controlling rust and being not easy, one rust value is gold absolutely, a rust word is estimated to big must being difficult to of loss that the whole world causes every year, the loss that rust causes to China at word every year is surprisingly big, for example: according to Chinese corrosion prevention association statistics, " at present, the annual loss that causes because of corrosive pipeline in the whole nation has broken through 3,000 hundred million yuan, is higher than the summation of general natural disaster.Along with the quickening of China's industrialization paces, the development of pipe-line construction, anticorrosion problem is also more outstanding ".Others except that pipeline are just more, as: the corrosion loss of boats and ships, sluice, open-air iron tower, steelframe, bridge etc. in household electrical appliance, various machinery equipment, various automobile, the water, the corrosion of the firearms of army, vehicle, military applications is scrapped and various anticorrosion a large amount of paint, the coating that consumes, other material etc., above-described comprehensive loss is estimated annual about 1.5 trillion yuan.In order to solve the corrosion problem, people are also continuing the new coating variety of development, for example: Shanghai a company has developed " anticorrosion series of patents technology of the novel underground pipe network of WUZI and product ", the Japanese has developed " safety dope peculiar to vessel ", the Frenchman has developed the paint of mouse bite preventing " can " etc., this explanation, at present, also there is not thoroughly to solve the new technology of iron steel corrosion problem in the world, new mode is still made an issue of on " preventing " word, the commentaries on classics of spinning in the circle of paint, coating, only take stopgap measures, it is not all right not effecting a permanent cure.Iron steel corrosion chronic disease is controlled for a long time and is not completely cured, and is that people also do not operate on to its rust root, as the saying goes: " the shovel grass does not dig up the roots, and spring breeze blows and gives birth to ", to cure the symptoms, not the disease, enamelled coating comes off to become rusty and gives birth to again, and the present invention will remove its root.

(2) technical scheme that solves its technical problem and adopted: the present invention adopts based on iron ore, match several nonferrous metals ores, go out different with ordinary steel by blast furnace and converter smelting, the new sections steel of distinguishing to some extent with stainless steel of the 3rd class, the iron ore that its each kind is used fluctuates not quite, but several nonferrous metals ores that use need be adjusted as requested, its fuel, auxiliary material is constant, this type of new iron steel not only has the antioxygen antiseptic power, its rust-proof effect is identical with stainless steel, and the color of each kind is different, is about consistent eternal colour, or else use any protection, so name: antirust colored steel alloy.Its technological method is; Look into reason, change structure, the rust cleaning root:

1, look into reason: all iron steel work are corrosion easily all, mainly be prove definitely inferior with oxygen due to, just a little less than the antioxygen antiseptic power of iron steel, the ability of oxygen is strong, weak person and powerhouse are for a long time opposed will be by long oxidation, and it is impossible wanting both absolute isolation, is exactly a kind of quarantine measures as brush paint, coating etc., fact proved every not, oxidized as before.The iron steel is why a little less than the antioxidant capacity, because it is the object that a kind of ferrous metal molecule constitutes, the molecule that is combined into by the particle of the atomic building of homogeneity, the molecule that is combined into than the atomic building particle of heterogeneous non-ferrous metal is thicker, and globule size is even inadequately, in conjunction with undertighten, fine slit is arranged, can from the fracture of iron or steel with the naked eye or magnifying glass see this kind situation.So the various steel that roll into must be through strict check, finding has crackle, pore, folder sand person, put in order, and its degree of depth, area exceed standard and just be judged to waste product; Will detecting a flaw with gamma defectoscope in the major parts of steel manufacturing machinery equipment such as axle center etc., if find that there are crackle, pore, folder sand person in inside, must scrap.The quality of the antioxygen of ferrous metal product own is just poor, adds the defective of structure difference, just is to be weak person, the basic reason of Here it is steel and the long-term corrosion of goods thereof in face of powerful oxidizing power.

2, change structure: the why easily corrosion of iron steel, be that it exists that quality is poor, the defective of structure difference, the closing to be and be weak person of two differences, long-term and powerhouse---keep out among oxygen hostile incessantly, time is grown slightly and is not just resisted, war is for a long time most certainly failed under weak, strong clearly demarcated situation, so the ferrous metal object is wanted oxidized corrosion; Oxygen is a kind of ubiquitous, seamless gaseous matter of not going into, to the mankind's benefit a lot, very big, people also be unable to do without it a moment, still, oxygen also has dual character, and is favourable, and fraud is also arranged, in brief, it is aided the powerhouse, and weak person is taken advantage of mutually.Between weak, strong, help weak person---iron/steel, defeat the powerhouse---oxygen, make them evenly matched, convert enemies into friends, to live with peacefully, this benefits to human society.For this reason, should change structure, with the thing of single metallic molecule structure, change the iron steel of multiple metallic molecule structure into, just can overcome that its quality is poor, the shortcoming of structure difference, change weak person is powerhouse, strong powerhouse! Just has not corrosion again of antioxidant capacity.Its root problem is, at first will change the cast iron ingredient structure, with the iron ore is exactly mainly to match several nonferrous metals ores that account for iron ore the last 1/3, goes out the antirust colored pig iron by blast-furnace smelting, and antirust iron has been arranged, and just can produce antirust steel, shuts out antirust various steel.Adopt this simple and easy mode, just can solve the hard nut to crack that does not always have solution, reach the purpose of getting twice the result with half the effort, save the various nuisance of people, exempt all worries.

3, rust cleaning root: blast furnace is carried out new mission, and converter, milling train adopt software engineering to combine with hardware technologies such as ironmaking, steel-making, steel rolling with closelying follow, and also need not increase, change equipment and investment, just can implement as early as possible.In the new millennium, New Economy Era, to handle affairs by the objective law of market economy, save the production firm of nonferrous materials, middle-chains such as dealer, directly use every utilizable various nonferrous metals ores by iron work, arrange in pairs or groups with iron ore, smelt the antirust colored pig iron by blast furnace is disposable---the thick antirust colored steel of type, for steel-making or cast iron molten iron is provided, steel-making provides base for steel rolling, ingot, the rolling various required steel of steel rolling, this is basic identical with the technical process of producing ordinary steel, implement not so difficult, difficult is iron work, increase a few thing amount, do the work that can accomplish again that some were never done in the past.This historical new task is mainly finished by blast furnace, and blast furnace is king in the stove of metallurgical industry, and its volume size has, several hectosteres of little person, big several kilosteres of person, its throughput capacity is surprisingly big, its feature is: the height tripe is very much not selected and is chewed, and it is hungry soon to have the digestion of an ostrich, and outeat draws manyly.Blast furnace has only staple food grain (iron ore), pickles (auxilliary ore deposit) to eat in the past, the pig iron quality that output is come is poor, irresistance sees that oxygen just gets rusty, just as a pregnant woman, have only meal and pickles to eat, nonnutritive product, fetus just lack nutrition physique in ma's belly poor, or underdevelopment, how sick the baby who is born is just, perhaps dead.The two all is due to the congenital defect, the disease of congenital defect, be difficult to the day after tomorrow remedy, be difficult to cure, iron and steel get rusty for a long time, and to can't resolve be exactly this reason, especially the corrosion of the pig iron does not also attract much attention, the global pig iron is all spent its all one's life in corrosion, have no precedent the stainless pig iron, the steel non-corrosive, at first to solve the root problem of not corrosion of the pig iron, say complexity, also simple in fact, change food prescription to blast furnace, increase several nutritious prod---nonferrous metals ore, problem has just solved.It draws up prescription row back:

The easy rust pig iron of original formulation=iron ore+coke+auxiliary material=monometallic constituent structure.

Antirust, the colored pig iron of new prescription=iron ore-many kinds of nonferrous metals ore 34-40%+ of 34-40%+ coke+auxiliary material=multiple metal ingredient structure.It is as follows just to intend the metal content prescription.

One of prescription: iron 66%, manganese 17%, chromium 15%, molybdenum 5%, rhodium 5% add up to 108%;

Two of prescription: iron 66%, antimony 16%, tungsten 14%, chromium 6%, copper 6% add up to 108%;

Three of prescription: iron 60%, chromium 20%, nickel 18%, molybdenum 6%, rhodium 4%, carbon 0.2%, added up to for 108.2% (this kind steel is used for the corrosion of shipbuilding oceangoing ship energy sea water resistance chlorion), more than three kinds of prescriptions, can be according to grade with the ore deposit, calculate the proportion of smelting 1 ton of required various ore of antirust iron and prepare burden, have 8% to be that loss rate is blown in steel-making in its component content, also have many nonferrous metals ores for the collocation use, development company can select for use as requested voluntarily, and this side is only for reference.

(3) beneficial effect against existing technologies: the present invention is worth outstanding, and is significant, and technique effect is very good, and economic benefit and social benefit are very remarkable:

1, technique effect is very good:

(1) do not increase equipment and instrument, do not change existing equipment, do not invest, the easily row that is easy to implement, drop into little, output is big, the cycle is short, can receive that vertical rod sees the effect of shadow;

(2) technological process of production is constant, can save the whole process and the expense of independent smelting nonferrous materials, saves technological process and expense that the refining stainless steel melts nonferrous materials separately, reduces loss;

(3) the antirust steel of antirust pig iron refining, the various steel that roll, its rust-proof effect is identical with stainless steel, and its kind is more than stainless steel, and the scope of application is greater than stainless steel, and use properties is better than stainless steel;

(4) the various steel of antirust pig iron refining, various steel and the goods that roll into, and the color of ironcasting is inside and outside the same, is eternal colour, does not need all impregnating material, need not spend to do anticorrosion again;

(5) work-ing life of antirust iron steel, comparable ordinary steel prolonged more than 5 times, the high approximately 60%-70% of its price, and still low more than 2-4 times than stainless steel, the user is with the antirust steel of first-selection;

(6) antirust iron steel has overcome many shortcomings of common iron steel, has had both stainless advantage, just saves natural resources, solves the anticorrosion difficulty of user, and meeting the market requirement increases economic benefit and social benefit, will be the only way which must be passed of iron steel industrial development.

2, remarkable in economical benefits:

Ordinary steel and stainless price differential are excessive, and its price including tax is: the sheet material price: 13000 yuan of stainless steels, 3000 yuan of ordinary steels, 4.33 times of price differentials; Tubing price: 22000 yuan of stainless steels, 4500 yuan of ordinary steels, 4.89 times of price differentials; Section bar price: 21000 yuan of stainless steels, 2700 yuan of ordinary steels, 7.78 times of price differentials; 1200 yuan/ton of the pig iron, 64%, 90 yuan/ton of smart iron ore grade.For the economic benefit of antirust iron steel is described, be that the example measuring and calculating is as follows only with one of prescription in the technical scheme:

Ton iron component content: iron 66%, manganese 17%, chromium 15%, molybdenum 5%, rhodium 5%;

Ore grade: iron ore 64%, manganese ore 62%, chrome ore 54%, molybdenum ore 52%, rhodium ore deposit 50%;

With iron ore amount and the amount of money=1.564t * 66%=1.032t * 90 yuan=92.88 yuan;

With manganese ore amount and the amount of money=1.614 * 17%=0.274t * 320 yuan=87.68 yuan;

With chrome ore amount and the amount of money=1.852 * 15%=0.278t * 320 yuan=90.62 yuan;

With molybdenum ore amount and the amount of money=1.924 * 5%=0.096t * 330 yuan=31.68 yuan;

With rhodium ore deposit amount and the amount of money=2t * 5%=0.100t * 334 yuan=33.40 yuan;

Ton iron adds up to: 5 kinds of mining amount 1.78t, 336.26 yuan of the amount of money.

In 336.26 yuan, should deduct few with iron ore 0.532t * 90 yuan=47.88 yuan, actual with the ore deposit amount of money=336.26 yuan-47.88 yuan=288.38 yuan.

Antirust pig iron average price=1200 yuan+288 yuan=1488 yuan * 10% overheads=269 yuan+1488 yuan=1637 yuan;

Antirust steel average price=1637 yuan * 9% blows loss rate=147 yuan+1637 yuan=1784 yuan * 6% overheads=107 yuan+1784 yuan=1891 yuan;

Antirust steel average price=1891 yuan * 8% rolls loss rate=151 yuan+1891 yuan=2042 yuan * 10% overheads=204 yuan+2042 yuan=2246 yuan * 14% tax=314 yuan+2246 yuan=2560 yuan (containing the tax cost price).

Antirust steel just intend selling price, profit, interest rate and with ordinary steel, stainless ratio:

The sheet material price: 5000 yuan, 2440 yuan of profits, interest rate 48.8%; Than 3000 yuan of ordinary steel, many 2000 yuan, high by 66.67%; Than stainless 13000 yuan, few 8000 yuan, low 1.6 times;

Tubing price: 4240 yuan of 6800 yuan, profit, interest rate 62.35%; Than 4500 yuan of ordinary steel, many 2300 yuan, high by 51.11%; Than stainless 22000 yuan, few 15200 yuan, low 2.24 times;

The section bar price: 5200 yuan, 2640 yuan of profits, interest rate 50.77%; Than 2700 yuan of ordinary steel, many 2500 yuan, high by 92.59%; Lack 15800 yuan, low 3.04 times than stainless 21000 yuan.

For further specifying economical efficiency, according to above-mentioned price and ordinary steel profit 30% is certificate, enumerates a family and produces 2000000 tons of steel per year (wherein: 1,000,000 tons of sheet materials, 500,000 tons of tubing, 500,000 tons of section bars) medium-sized enterprise is an example, and its output value, forecasting of profit are as follows:

Sheet material: the former output value=1,000,000 ton * 3000 yuan=3,000,000,000 yuan, hundred million yuan of former profit=3,000,000,000 yuan * 30%=9; The new output value=1,000,000 tons * 5000 yuan=5,000,000,000 yuan increases by 2,000,000,000 yuan than the former output value, amplification 66.67%, and new profit=1,000,000 tons * 2440 yuan=24.4 hundred million yuan increases by 15.4 hundred million yuan than former profit, amplification 171.11%;

Tubing: the former output value=500,000 ton * 4500 yuan=22.5 hundred million yuan, hundred million yuan of former profit=22.5 hundred million yuan * 30%=6.75; The new output value=500,000 tons * 6800 yuan=3,400,000,000 yuan increases by 11.5 hundred million yuan than the former output value, amplification 51.11%, and new profit=500,000 tons * 4240 yuan=21.2 hundred million yuan increases by 14.45 hundred million yuan than former profit, amplification 214.07%;

Section bar: the former output value=500,000 ton * 2700 yuan=13.5 hundred million yuan, hundred million yuan of former profit=13.5 hundred million yuan * 30%=4.05; Hundred million yuan of the new output values=500,000 tons * 5200=26 increase by 12.5 hundred million yuan than the former output value, amplification 92.60%, and new profit=500,000 tons * 2640 yuan=13.2 hundred million yuan increases by 9.15 hundred million yuan than former profit, amplification 225.93%.

2,000,000 tons of steel add up to: 6,600,000,000 yuan of the former output values, 19.8 hundred million yuan of former profits; 11,000,000,000 yuan of the new output values increase by 4,400,000,000 yuan than the former output value, amplification 66.66%, and 58.8 hundred million yuan of new profits increase by 3,900,000,000 yuan than former profit, amplification 196.97%.

Three materials, three steel average prices are: 5666 yuan of antirust steel, 3400 yuan of ordinary steels.18666 yuan of stainless steels.Antirust steel is Duoed 2266 yuan than ordinary steel, and is high by 66.69%; Lack 13000 yuan than stainless steel, low 229.44%, both contained compositions are identical, the former comes out from the blast furnace viviparity, form through converter refining again, its quality and antioxygen preservative effect can not be lower than stainless steel, and price is low more than 2 times, not only solved user's rot-resistant difficulty of no longer spending, and work-ing life is longer more than 5 times than ordinary steel at least, is embedded in also imputrescibility of underground two a century, and its actual use price is also more much lower than the pig iron of 1200 yuan of t, this cries bright expensive tens percent, secretly low five, six times.

3, social benefit: to the people, to the country, human society is all had huge benefit.

(1) favourable to people's lives, healthy and helpful: water pipe, the natural gas tube of easy-to-rust often break down, cause and cut off the water, stop the supple of gas or steam, have a strong impact on the people's daily life, especially the iron rust serious harm human health in the water pipe, early there is disclosure in news media, " Chinese health care " the 3rd phase of this year is reported again: " the overweight metal content just too high levels of scale is first index that water pollutes; iron rust has polluted into the maximum harm that brings to people in the tap water pollution, and what harm was maximum is exactly the infringement of ferric oxide to human liver." in recent years people invented various tap water filters, strainer etc., big small shop has, the people who buys is also many; but produce little effect; so people have invented " pure water " again, for the moment between; big or small purified water factories is all over upright in all parts of the country; say so eaten pure water all kinds of diseases and ailments do not go into, alive for evermore, for this reason, selling water, to go into, absorb water the people more and more; its price is absorbed water the people and also will be bought than the high several times of ortho-water.Spend at most the most bothersome household electrical appliance and constituent parts hang over corrosion, the damage of conditioner outside window, frequent Maintenance and Repair, eliminate rust, spray paint, its corrosion, damage, replacing are fast, the real difficulty of common people is dealt with, as uses antirust steel instead and make, and these problems have not just existed yet.

(2) country and social constituent parts are of great benefit to, can avoid tremendous loss every year: the various Infrastructure of using the iron steel that easily becomes rusty to be built, various industrial goods, the agricultural articles for use, the military project articles for use, civil goods or the like, top priority after the completion will be carried out rotproofing to it exactly, as brush paint, coating, zinc-plated, plating chromium or spray paint, plastic-blasting, twine buffer zone etc. anticorrosion after, could install, assembling is come into operation, this antiseptic project will consume how much go into power every year, material resources, financial resources, probably also nobody added up separately, only how long pipe so also is unable to control or manage, corrosion as before after preservative coat comes off no matter how you protect all can not be treated for a long time, therefore, an anticorrosion process of the circulation that goes round and begins again has just appearred, till rotten can not the use, the annual loss that is caused adds anticorrosion expense, estimates about 1.5 trillion yuan.Also have the severe contamination problem of impregnating material to environment, air, water source, soil property, estimate that annual required various impregnating material are about 1,000 ten thousand tons, carry out anticorrosion to various new and old protection object, its impregnating material all is deleterious, as various paint, oil of bananas, tar-bitumen, petroleum pitch etc., from producing use, cyclic polluting year after year, the serious harm human beings'health, whom does this loss have calculate clearly? the material cancer of iron steel easy-to-rust is not thoroughly cured, and annual loss and pollution can be big year by year.Antirust iron steel is exactly the wonderful recipe of curing this cancer.

(3) benefit to progress of human society and development is bigger, benefit is more remarkable: global iron steel and various goods all will get rusty, the U.S., Japanese no exception, the iron steel develops soon, does not have its corrosion to get soon, the weak point in work-ing life, must increase turnout and usage quantity, quicken the exploitation of subterranean resource, may break through 1,000,000,000 tons of high pointes to world's output of steel in 2002, in the earth, dig out how many iron ores, raw coal, auxilliary ore deposit every year so? be example only with 1,000,000,000 tons of steel:

Need dig out iron ore=1,000,000,000 ton steel * ton ore deposit, 1.1 tons of iron * 2=2,200,000,000 tons of iron ores;

Need dig out raw coal=1,100,000,000 ton iron * 0.686 ton of coke * 1.4 ton cleaned coal * 2 tons of raw coal=21.1288 hundred million ton raw coal;

Need dig out auxilliary ore deposit=1,100,000,000 ton iron * 0.5 ton ore deposit=5.5 hundred million ton Wingdale, rhombspar etc.;

More than three add up to: 48.6288 hundred million tons, the produced quantity in 1 year that Here it is, output of steel is many more, produced quantity is also just big more, both are proportional to increase simultaneously.Disclose according to news media, the coal in the earth could be used two a century approximately, and so speed digs down, and have more than is needed two a century will dig light to coal! Wish to occur nearly evening this situation, the life that just has only the corrosion of leather iron steel allows its tread flaking change bone, and becoming different rust takes on a new look for stainless, and its work-ing life is extended to more than two a century, allows the usage period of limited resources extend to more than the millennium.
