Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам низколегированного чугуна, который может быть использован для изготовления деталей машин для формования стекла, пластмасс.The invention relates to the field of ferrous metallurgy, in particular to compositions of low-alloy cast iron, which can be used for the manufacture of machine parts for molding glass and plastics.
Известен чугун следующего состава, мас.%: углерод 3,0-4,8; кремний 0,02-0,8; марганец 0,01-1,5; ванадий 0,03-1,0; титан 0,02-0,6; фосфор 0,015-0,1; сера 0,01-0,05; медь 0,01-0,12; никель 0,02-0,3; кобальт 0,001-0,14; хром 0,02-0,9; алюминий 0,03-0,15; галлий 0,0001-0,0003; гафний 0,0001-0,004; железо - остальное [1].Known cast iron of the following composition, wt.%: Carbon 3.0-4.8; silicon 0.02-0.8; manganese 0.01-1.5; vanadium 0.03-1.0; titanium 0.02-0.6; phosphorus 0.015-0.1; sulfur 0.01-0.05; copper 0.01-0.12; nickel 0.02-0.3; cobalt 0.001-0.14; chrome 0.02-0.9; aluminum 0.03-0.15; gallium 0.0001-0.0003; hafnium 0.0001-0.004; iron - the rest [1].
Задача изобретения состоит в повышении качества поверхности изделий из чугуна.The objective of the invention is to improve the surface quality of cast iron products.
Технический результат достигается тем, что низколегированный чугун, содержащий углерод, кремний, марганец, фосфор, серу, медь, никель, хром, кобальт, алюминий, железо, дополнительно содержит теллур и бор при следующем соотношении компонентов, мас.%: углерод 4,0-4,4; кремний 1,2-1,6; марганец 0,03-0,07; фосфор 0,03-0,07; сера 0,03-0,07; медь 0,03-0,07; никель 0,4-0,6; хром 0,03-0,07; алюминий 0,01-0,03; теллур 0,0001-0,0003; бор 0,2-0,25; железо - остальное.The technical result is achieved by the fact that low-alloy cast iron containing carbon, silicon, manganese, phosphorus, sulfur, copper, nickel, chromium, cobalt, aluminum, iron, additionally contains tellurium and boron in the following ratio, wt.%: Carbon 4.0 -4.4; silicon 1.2-1.6; manganese 0.03-0.07; phosphorus 0.03-0.07; sulfur 0.03-0.07; copper 0.03-0.07; nickel 0.4-0.6; chromium 0.03-0.07; aluminum 0.01-0.03; tellurium 0.0001-0.0003; boron 0.2-0.25; iron is the rest.
В таблице приведены составы низколегированного чугуна.The table shows the compositions of low alloy cast iron.
В составе чугуна компоненты проявляют себя следующим образом. Комплексное введение в состав чугуна марганца, никеля, хрома, меди, алюминия обеспечивает ему мелкозернистое строение. Фосфор, образуя легкоплавкую эвтектику, состоящую из аустенита и фосфида железа, улучшает жидкотекучесть чугуна. Теллур стабилизирует карбиды. Бор повышает твердость сплава. Сера облегчает обрабатываемость твердого сплава с получением качественной поверхности.In the composition of cast iron, the components manifest themselves as follows. The complex introduction of manganese, nickel, chromium, copper, aluminum into the composition of cast iron provides it with a fine-grained structure. Phosphorus, forming a low-melting eutectic consisting of austenite and iron phosphide, improves the fluidity of cast iron. Tellurium stabilizes carbides. Boron increases the hardness of the alloy. Sulfur facilitates the machinability of the hard alloy to obtain a high-quality surface.
Изделия из чугуна могут быть отлиты в кокили, нагретые до температуры 400-450°C. Отливки подвергают нормализации при температуре 930-950°C и отпуску при температуре 700-720°C.Cast iron products can be cast into molds heated to a temperature of 400-450 ° C. Castings are subjected to normalization at a temperature of 930-950 ° C and tempering at a temperature of 700-720 ° C.
