Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам низколегированного чугуна, который может быть использован для изготовления деталей стеклоформующих машин.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 parts of glass-forming machines.
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, никель, хром, титан, кобальт, железо, дополнительно содержит церий, селен, неодим, празеодим, при следующем соотношении компонентов, мас.%: углерод 3,0-3,2; кремний 1,9-2,4; марганец 0,03-0,07; фосфор 0,03-0,07; сера 0,03-0,07; никель 0,1-0,15; хром 0,1-0,15; титан 0,03-0,07; церий 0,25-0,35; селен 0,03-0,07; неодим 0,1-0,15; празеодим 0,1-0,15; кобальт 0,03-0,07; железо - остальное.The technical result is achieved by the fact that low-alloy cast iron containing carbon, silicon, manganese, phosphorus, sulfur, nickel, chromium, titanium, cobalt, iron, additionally contains cerium, selenium, neodymium, praseodymium, in the following ratio, wt.%: Carbon 3.0-3.2; silicon 1.9-2.4; manganese 0.03-0.07; phosphorus 0.03-0.07; sulfur 0.03-0.07; nickel 0.1-0.15; chrome 0.1-0.15; titanium 0.03-0.07; cerium 0.25-0.35; selenium 0.03-0.07; neodymium 0.1-0.15; praseodymium 0.1-0.15; cobalt 0.03-0.07; 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, титана, селена обеспечивает ему мелкозернистое строение. Церий, неодим и празеодим раскисляют сплав. Фосфор, образуя легкоплавкую эвтектику, состоящую из аустенита и фосфида железа, улучшает жидкотекучесть чугуна. Селен и сера улучшают обработку сплава резанием и способствуют повышению качества поверхности чугунных изделий.In the composition of cast iron components manifest themselves as follows. The complex introduction of manganese, nickel, chromium, titanium, and selenium into the composition of cast iron provides it with a fine-grained structure. Cerium, neodymium and praseodymium deoxidize the alloy. Phosphorus, forming a low-melting eutectic consisting of austenite and iron phosphide, improves the fluidity of cast iron. Selenium and sulfur improve the machining of the alloy by cutting and contribute to improving the surface quality of cast iron products.
Изделия из чугуна могут быть отлиты в кокили, нагретые до температуры 400-450°С. Отливки подвергают нормализации при температуре 930-950°С и отпуску при температуре 700-720°С.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.
