Abstract
Description
Изобретение относится к области черной металлургии, а именно к составам сталей, которые могут быть использованы для изготовления отливок сложной конфигурации.The invention relates to the field of ferrous metallurgy, and in particular to compositions of steels that can be used for the manufacture of castings of complex configuration.
Известна сталь, содержащая, мас.%: углерод 0,1-0,55; кремний ≤1,0; марганец 0,2-3,0; хром 0,01-1,0; никель 0,005-2,0; молибден ≥0,005; магний 0,0005-0,05; бор 0,0002-0,005; фосфор ≤0,03; медь 0,005-2,0; титан ≥0,005; ниобий ≥0,005; цирконий ≥0,005; кальций 0,0005-0,05; азот ≥0,005; железо и неизбежные примеси - остальное [1].Known steel containing, wt.%: Carbon 0.1-0.55; silicon ≤1.0; manganese 0.2-3.0; chromium 0.01-1.0; nickel 0.005-2.0; molybdenum ≥0.005; magnesium 0.0005-0.05; boron 0.0002-0.005; phosphorus ≤0.03; copper 0.005-2.0; titanium ≥0.005; niobium ≥0.005; zirconium ≥0.005; calcium 0.0005-0.05; nitrogen ≥0.005; iron and inevitable impurities - the rest [1].
Задачей изобретения является повышение литейно-технологических свойств стали.The objective of the invention is to improve the casting and technological properties of steel.
Технический результат достигается тем, что в стали, содержащей углерод, кремний, марганец, хром, никель, молибден, магний, бор, фосфор, медь, титан, ниобий, цирконий, кальций, азот, железо, компоненты находятся при следующем соотношении, мас.%: углерод 0,2-0,4; кремний 0,2-0,4; марганец 0,2-0,4; хром 1,0-1,5; никель 1,0-1,5; молибден 0,2-0,4; магний 0,002-0,004; бор 0,2-0,4; фосфор 0,02-0,04; медь 0,2-0,4; титан 0,2-0,4; ниобий 0,2-0,4; цирконий 0,2-0,4; кальций 0,01-0,02; азот 0,1-0,2; железо - остальное.The technical result is achieved in that in a steel containing carbon, silicon, manganese, chromium, nickel, molybdenum, magnesium, boron, phosphorus, copper, titanium, niobium, zirconium, calcium, nitrogen, iron, the components are in the following ratio, wt. %: carbon 0.2-0.4; silicon 0.2-0.4; manganese 0.2-0.4; chrome 1.0-1.5; nickel 1.0-1.5; molybdenum 0.2-0.4; magnesium 0.002-0.004; boron 0.2-0.4; phosphorus 0.02-0.04; copper 0.2-0.4; titanium 0.2-0.4; niobium 0.2-0.4; zirconium 0.2-0.4; calcium 0.01-0.02; nitrogen 0.1-0.2; iron is the rest.
В таблице приведены составы стали.The table shows the compositions of steel.
В составе стали компоненты проявляют себя следующим образом. Хром и бор стабилизируют карбиды, придают стали необходимую твердость. В химически связанном состоянии с ванадием, титаном или ниобием азот, образуя нитриды, становится легирующим элементом, улучшающим структуру и механические свойства стали. Фосфор повышает жидкотекучесть стали. Молибден повышает прочность сплава, никель и медь увеличивают его пластичность. Магний и кальций выполняют функцию раскислителей. Цирконий способствует образованию мелкозернистой структуры стали.In the steel composition, the components manifest themselves as follows. Chrome and boron stabilize carbides, give the steel the necessary hardness. In a chemically bound state with vanadium, titanium or niobium, nitrogen, forming nitrides, becomes an alloying element that improves the structure and mechanical properties of steel. Phosphorus increases the fluidity of steel. Molybdenum increases the strength of the alloy, nickel and copper increase its ductility. Magnesium and calcium act as deoxidizers. Zirconium contributes to the formation of a fine-grained steel structure.
Сталь может быть выплавлена в индукционных вакуумных печах. Основной исходный материал для выплавки стали - стальной лом, специально приготовленная шихта. Термическая обработка стали включает закалку при температуре 850°С в масло и отпуск при температуре 530°С.Steel can be smelted in induction vacuum furnaces. The main source material for steelmaking is steel scrap, a specially prepared charge. Heat treatment of steel includes quenching at a temperature of 850 ° C in oil and tempering at a temperature of 530 ° C.
