Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам чугуна, который может быть эффективно использован в машиностроение.The invention relates to the field of ferrous metallurgy, in particular to compositions of cast iron, which can be effectively used in mechanical engineering.
Известен чугун, включающий мас.%: углерод 1,5-4,0; кремний 1,5-6,0; марганец 0-0,3; медь 0-8,0; хром 0-3,0; молибден 0-0,5; бор и цирконий не более 0,5; железо - остальное [1].Known cast iron, including wt.%: Carbon 1.5-4.0; silicon 1.5-6.0; manganese 0-0.3; copper 0-8.0; chrome 0-3.0; molybdenum 0-0.5; boron and zirconium not more than 0.5; iron - the rest [1].
Задача изобретения - повышение прочности чугуна.The objective of the invention is to increase the strength of cast iron.
Технический результат достигается тем, что чугун, содержащий углерод, кремний, марганец, медь, хром, молибден, цирконий, бор, отличающийся тем, что компоненты находятся при следующем соотношении, мас.%: углерод 3,0-3,8; кремний 3,0-3,6; марганец 0,5-1,5; медь 0,5-1,5; хром 2,0-4,0; молибден 4,0-6,0; цирконий 1,0-2,0; бор 0,01-0,1; железо - остальное.The technical result is achieved in that the cast iron containing carbon, silicon, manganese, copper, chromium, molybdenum, zirconium, boron, characterized in that the components are in the following ratio, wt.%: Carbon 3.0-3.8; silicon 3.0-3.6; manganese 0.5-1.5; copper 0.5-1.5; chrome 2.0-4.0; molybdenum 4.0-6.0; zirconium 1.0-2.0; boron 0.01-0.1; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
Присутствующие в составе чугуна компоненты проявляют себя следующим образом. Молибден и хром упрочняют твердый раствор. Бор стабилизирует карбиды. Медь вызывает дисперсионное твердение отливок. Цирконий способствует измельчению зерна.The components present in the composition of cast iron manifest themselves as follows. Molybdenum and chromium strengthen the solid solution. Boron stabilizes carbides. Copper causes precipitation hardening of castings. Zirconium contributes to grain refinement.
Чугун выплавляют в электропечах и отливают формы. Отливки подвергают обезуглероживающему отжигу при температуре 1000°С в течение 5-7 часов, после которого сплав, по существу, превращается в сталь. Затем отливки подвергают закалке на воздухе с отпуском при температуре 250°С. Предел прочности при растяжении полученного материала составит ~1000 МПа.Cast iron is smelted in electric furnaces and molds are cast. The castings are subjected to decarburization annealing at a temperature of 1000 ° C for 5-7 hours, after which the alloy essentially turns into steel. Then the castings are subjected to air quenching with tempering at a temperature of 250 ° C. The tensile strength of the obtained material will be ~ 1000 MPa.
