Description
Technical field
The present invention relates to a kind of pipeline, relate in particular to the antiseptic and rustproof pipeline of a kind of abrasion-resistant metal.
Background technology
Material damage has three kinds of principal modes: namely rupture, corrode and wear and tear.Although fret wear seldom causes the catastrophic harm of metal works unlike other two kinds of forms, its financial loss that causes is quite surprising.Data shows according to statistics: in the mechanical component that lost efficacy, nearly 75% "--the 80%th, belong to that galling causes.The nearly 30%-50% of the energy of supply equipment is consumed in the friction and wear process.Parts depreciation not only influenced the performance of machinery equipment end-use performance after losing efficacy, and needed to consume a large amount of human and material resources replacing accessories and servicing installation.By the financial loss that wearing and tearing cause, about 1,200 hundred million dollars/year of the U.S., about 50,000,000,000 mark/years of Germany.According to statistics in 2005, the domestic annual metal wear resistant material that consumes reached more than 5,000,000 tons approximately, is worth more than 55,000,000,000 yuan.This shows that galling is to cause one of principal mode of mechanical component inefficacy, galling is the major issue that is related to the national economic development.In today of scientific and technical high speed development, each department of national economy has all proposed requirements at the higher level to wearing quality, reliability and the precision of mechanical means.Therefore, friction phenomenon and the abrasion mechanism of research metal are inquired into the various factors that influence is worn and torn, and improve the fastness to wear of metal, and development and development of new wear-resistant material become the important topic that the scientific worker faces already.
In industrial circle, abrasive wear is most important a kind of wear type, accounts for 50%.The abrasive wear phenomenon extensively is present in most of mechanical means, particularly at mining machinery, agricultural machine, engineering machinery and foundry machinery etc., and as various rubble machineries, excavator, tractor, coalcutter, the conveyor of transportation industry, slush pump etc.Only be used for high-abrasive material that rock crushing plant such as Hubei Province formula stoning machine, hammer crusher, reaction type stoning machine, impact breaker (sand machine processed), cone crusher, double-roll type stoning machine, slush pump etc. consume every year just above 150,000 tons, be worth more than 2,000,000,000 yuan.Along with the quickening of transport development speed, wearing and tearing have become the transportation industry ubiquity and have become the major cause that causes equipment failure or material damage.In order to improve the service efficiency of equipment such as transportation industry rock crushing plant and concrete pump, reduce frequency of maintenance, reduce production costs.Therefore, research and development a new generation high-abrasive material reduces galling, and the development of China's transport development is had great importance.
In order to obtain more high rigidity and wear resistance, generally need to improve carbon and alloying element content, when carbon content increases, often cause material crackle to occur because heat treating regime is improper in the heat treatment process, existing heat treating regime is difficult to be applied in the casting high-carbon high-alloy material heat treatment.
For the high quality steel material, the general high chromium steel that adopt also adopt rapid steel and matrix steel sometimes, but effect are all not ideal more.This is because exist thick M7c3 eutectic carbides in the high chromium steel, even conducting forging processing also can only partly be smashed, causes thus that obdurability is low and causes wear resistance relatively poor.Though the rapid steel wear resistance is very high, there is thick eutectic carbides, toughness is relatively poor, easy tipping in the use, and processing and thermal treatment cost are higher.The matrix steel obdurability is better, but because almost all dissolvings of carbide when quenching, so wear resistance is not ideal enough.Crystal grain is easily grown up during matrix steel quenching austenitizing, as thin blade tip angle tool and mould quasi-cleavage crack takes place easily, and use properties is also undesirable.
The high alloy mould steel mainly uses the operating mode of having relatively high expectations in antagonism tempering and wear resistance, and the low-alloy mould steel mainly uses to less demanding but higher to the toughness reguirements occasion of temper resistance.In actual production, in order to enhance productivity and work-ing life, though requirement is not very high occasion to temper resistance, also often select the high alloy mould steel.But, along with the development of producing, people recognize the less demanding processing occasion of a lot of temper resistances gradually, use high quality steel because not utilizing its high-temperature resistant tempered property, it is a kind of using method of wasting alloying element, on the contrary also can be owing to the alloy amount be excessive, make the carbide alligatoring and do not reach due toughness.But for the low-alloy mould steel, when using working temperature to surpass tempering temperature, often do not reach due temper resistance, cause wear resistance low excessively.
In the alloy designs of actual mould steel, for intensity, wear resistance and the temper resistance that improves high-carbon low-alloy steel, often considering increases its alloy content, makes it to become the high-carbon Medium Alloy Steel.But the high-carbon Medium Alloy Steel may cause carbide to assemble to grow up, to be difficult for refinement, and performances such as the obdurability of steel, fatigue crack-resistant are had certain influence.And owing to improved quenching temperature, cause the quenching remained austenite content to increase, and need improve tempering temperature again and decompose to promote residual austenite, hardness is descended, influenced the use properties of Medium Alloy Steel.Mould steel always lacks high-carbon Medium Alloy Steel kind both at home and abroad, therefore need develop suitable low temperature quenching, has some amount in the microstructure, the tiny carbide of size and distributional pattern, have higher hardness and obdurability simultaneously, to satisfy the high-carbon interalloy mould steel that use properties requires.Forging rolling processing and the thermal treatment process purpose that be difficult to reach refinement of the middle and high steel alloy of existing most of high-carbon by routine, and can increase difficulty on the technology by forging rolling processing or the thermal treatment process of complexity, and consume the more energy, often also be difficult to the degree of refinement that reaches desirable.Because high-carbon alloy steel is difficult relatively by the target that alloying reaches refinement, although research both at home and abroad is more, does not also have clear and definite solution.
Corrosion is the one of the main reasons that causes that metallic conduit destroys and lost efficacy.Cause the environment that corrosion takes place metallic substance to mainly contain two big classes: a class is physical environment, as more weak corrosive environments such as natural atmosphere, ocean, soil; Another kind of is industrial environment, as severe corrosive industrial gasses and industry solution etc.In the corrosion with normal physical environment, its form of corrosion belongs to galvanic corrosion and biochemical corrosion, effect a little less than, corrosion speed is slower, the short-term corrosion failure is less, but potential hazard is bigger; And if metal is when being used for purposes such as severe corrosive industrial gasses, solution environmental and sewage discharge, and its form of corrosion belongs to chemical corrosion, and effect is strong, and corrosion reaction is violent, and destructiveness is very strong.So the corrosion of metallic conduit is relevant with its residing environment and delivery medium.So, in order to improve the work-ing life of metallic conduit,
Corrosion protection coating must possess following essential characteristic:
(1) corrosion resistance and good.Refer to that coating all is stable to the corrosive medium that it contacts physically and chemically, neither be corroded medium swelling, dissolving are not yet destroyed, are decomposed by corrosive medium.
(2) ventilation property and water permeability are little.Corrosion of metal under the coating, be because water and oxygen etc. are penetrated on the interface of coating and metal causes in essence, so must select little filmogen and the big filler of shielding effect of ventilation property, and making coating reach certain thickness, critical thickness depends on the character of film-forming resin and the disposition of metallic surface etc.
(3) good sticking power and certain mechanical strength to be arranged.Whether coating can be attached on the metallic matrix securely, is that can coating bring into play one of key factor of protective effect.
Yet corrosion protection coating is difficult to take into account water tolerance, anti-fouling effect usually in the prior art, and resistance to elevated temperatures.
Summary of the invention
