Abstract

The invention relates to a low-chromium cast iron/gray iron-base WC particle-reinforced surface composite material. The invention is characterized in that the composite material is prepared from the following raw materials in parts by weight: 80-120 parts of quartz sand, 3-5 parts of sodium bentonite, 2-4 parts of Na2CO3, 2-4 parts of white latex, 0.5-1.5 parts of CMC (carboxymethyl cellulose), 0.05-0.15 part of sodium dodecyl benzene sulfonate, 0.02-0.10 part of octanol and the balance of Fe. The WC composite material has the advantages of favorable toughness, high hardness, high shock load and high abrasion resistance of abrasive grains. The WC phase is tightly combined with the metal base, and thus, has favorable interfacial corrosion resistance. The WC particles are used as a reinforcement phase and combined with the low-chromium cast iron, thereby forming the favorable abrasion-resistant composite material.

Description

A kind of low-chromium cast-iron, grey iron-based WC particle strengthen composite surface material
Technical field
The present invention relates to high-abrasive material technical field, relate in particular to a kind of low-chromium cast-iron, grey iron-based WC particle enhancing composite surface material.
Background technology
Industrial expansion requires more and more higher to the wear resistance of material now, the departments such as metallurgy, mine, building materials, electric power, chemical industry, coal and agricultural need various crushing and grinding equipment, mining machinery, engineering machinery and agricultural machine, the consumable accessory of these equipment will be subject to the wearing and tearing of the various materials such as sandstone, ore, soil and grinding element, will consume every year a large amount of metals.According to incomplete statistics, the 1/3-1/2 of the energy is consumed in friction and wear; Concerning material, approximately 80% part failure is caused by wearing and tearing, wherein account for 50% because of what abrasive wear was lost efficacy, in industries such as metallurgy, mine, building materials, electric power, chemical industry, coal, agricultural machinery, its wearing and tearing account for the ratio that production cost is larger, as the high-abrasive material being consumed in mine muck, grinding process accounts for the half of its beneficiation cost.Add up according to the China Metal material council, within 1986, China is only in metallurgical mine, cement, the large industry of electric power three, because causing the foundry goods losing efficacy, abrasive wear just reaches 1,450,000 tons, account for China 3% left and right of iron and steel ultimate production then, and Yunnan Province is metallurgy, building materials, thermoelectricity, the more province of chemical enterprise, there is abundant nonferrous metal ore resource, its annual all kinds of main wearing piece consuming reaches 80,000 tons according to wear-and corrosion-resistant heat-stable material association of Yunnan Province statistics total amount consumed in 1994, is worth 2.5 hundred million yuan.And including all wear forms, wearing piece year total amount consumed in Yunnan Province's, more than 140,000 tons, is worth more than approximately 500,000,000 yuan.Along with Yunnan Province develops non-ferrous metal exploitation processing, phosphorous chemical industry for these several years as one of four large mainstay industries, annual the consumed high-abrasive material in Yunnan Province also will increase greatly.
When synergic wear operating mode, refer to wearing and tearing and attrition and attack and deposit or wearing and tearing and high temperature deposit that interaction between them has been aggravated the wear out failure of part.This class operating mode is extensively present in the industries such as metallurgy, building materials, mine, thermoelectricity, chemical industry, and as the various transh pumps that mine is used, its flow passage components are subject to again the corrosion of medium in taking up wear, and work-ing life is extremely short; And for example the various smart mine tailings of ore dressing carry, the pipeline of chemical plant waste sludge discharge, be all subject to the dual function of material abrasion and corrosion dielectric corrosion; Vertical water stall discharging tower, the dual function that need bear abrasive wear and high temperature; The needed guide plate of rolling in steel industry is also the dual function of taking up wear and high temperature.The quantity of the component that use under these synergic wear working conditions is surprising, taking sand pump and transh pump as example: 98 flow passage components of being only national non-ferrous metal industry consumption reach 5.87 ten thousand tons.Add up according to high-abrasive material association of Yunnan Province, within 1994, the whole province's transh pump year military service amount is about 7500 left and right, and the flow passage components material of current transh pump used adopts cast alloy iron, cast steel, and its life-span is very short, be only 15-30 days general work-ing life, have even less than 7 days.Consume impurity flow passage part 3000-3400 ton the whole province's year, this has not only consumed a large amount of metallic substance, and due to heavy wear, the efficiency of transh pump reduces greatly, and energy consumption increases.Because frequent replacing caused equipment and even production line stop, greatly reduce production efficiency simultaneously.Thereby this financial loss is huge every year.Thus, develop a kind ofly can under synergic wear operating mode, use, plastics on new materials that the life-span is long seems very important.
