Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам сталей, используемых для изготовления фасонных отливок.The invention relates to the field of ferrous metallurgy, in particular to compositions of steels used for the manufacture of shaped castings.
Известна сталь, содержащая, мас. %: углерод 0,9-1,4; марганец 7,0-13,0; кремний 0,3-0,9; ванадий 0,01-0,35; хром 0,2-1,0; азот 0,01-0,06; кальций 0,001-0,02; РЗМ 0,002-0,05; железо - остальное [1].Known steel containing, by weight. %: carbon 0.9-1.4; manganese 7.0-13.0; silicon 0.3-0.9; vanadium 0.01-0.35; chrome 0.2-1.0; nitrogen 0.01-0.06; calcium 0.001-0.02; REM 0.002-0.05; iron - the rest [1].
Задачей изобретения является повышение жидкотекучести стали.The objective of the invention is to increase the fluidity of steel.
Технический результат достигается тем, что сталь, содержащая углерод, марганец, кремний, ванадий, хром, азот, кальций, железо, дополнительно содержит цинк, фосфор и бор при следующем соотношении компонентов, мас. %: углерод 0,9-1,4; марганец 7,0-13,0; кремний 0,3-0,9; ванадий 0,45-0,55; хром 0,05-0,1; азот 0,0001-0,00012; кальций 0,0003-0,0005; цинк 0,001-0,002; фосфор 0,1-0,2; бор 0,15-0,3; железо - остальное.The technical result is achieved in that the steel containing carbon, manganese, silicon, vanadium, chromium, nitrogen, calcium, iron, additionally contains zinc, phosphorus and boron in the following ratio of components, wt. %: carbon 0.9-1.4; manganese 7.0-13.0; silicon 0.3-0.9; vanadium 0.45-0.55; chrome 0.05-0.1; nitrogen 0.0001-0.00012; calcium 0.0003-0.0005; zinc 0.001-0.002; phosphorus 0.1-0.2; boron 0.15-0.3; iron is the rest.
В таблице приведены составы стали.The table shows the compositions of steel.
Повышение жидкотекучести стали достигается за счет комплексного влияния компонентов, входящих в ее состав. Хром и бор стабилизируют карбиды. Бор и азот, введенные совместно с ванадием, увеличивает жидкотекучесть сплава. Кальций и цинк раскисляют сплав.The increase in the fluidity of steel is achieved due to the complex effect of the components included in its composition. Chrome and boron stabilize carbides. Boron and nitrogen, introduced together with vanadium, increase the fluidity of the alloy. Calcium and zinc deoxidize the alloy.
Сталь может быть выплавлена в электропечах. Сталь подлежит термической обработке по режиму: закалка при температуре 1180°С на воздухе; старение при температуре 750-800°С.Steel can be smelted in electric furnaces. Steel is subject to heat treatment according to the regime: quenching at a temperature of 1180 ° C in air; aging at a temperature of 750-800 ° C.
