Abstract
Description
Изобретение относится к области черной металлургии, а именно к составам хромистого чугуна, который может быть использован в станкостроении.The invention relates to the field of ferrous metallurgy, and in particular to compositions of chromium cast iron, which can be used in machine tool construction.
Известен чугун, содержащий, мас.%: углерод 2.0-5,0; кремний ≤1,5; марганец ≤1,2; хром ≤12,0; никель ≤5,5; ванадий 3,0-10,0; титан ≤2,0; медь ≤2,0; ниобий ≤7,0; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 2.0-5.0; silicon ≤1.5; Manganese ≤1.2; chrome ≤12.0; nickel ≤5.5; vanadium 3.0-10.0; titanium ≤2.0; copper ≤2.0; niobium ≤7.0; iron - the rest [1].
Задачей изобретения является повышение твердости чугунаThe objective of the invention is to increase the hardness of cast iron
Технический результат достигается тем, что чугун, содержащий углерод, кремний, марганец хром, никель, ванадий, титан, медь, ниобий, железо, дополнительно включает азот при следующем соотношении компонентов, мас.%: углерод 3,2-3,8; кремний 0,6-1,0, марганец 5,0-6,0; хром 8,0-10,0; титан 0,1-0,2; медь 0,1-0,2; ниобий 2,5-3,0, азот 0,1-0,15; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, chromium manganese, nickel, vanadium, titanium, copper, niobium, iron, additionally includes nitrogen in the following ratio of components, wt.%: Carbon 3.2-3.8; silicon 0.6-1.0, manganese 5.0-6.0; chrome 8.0-10.0; titanium 0.1-0.2; copper 0.1-0.2; niobium 2.5-3.0, nitrogen 0.1-0.15; iron is the rest.
В таблице приведены составы чугунаThe table shows the composition of cast iron
Повышение твердости чугуна достигается за счет комплексного влияния компонентов, входящих в его состав. Ниобий упрочняет твердый раствор. В химически связанном состоянии с ванадием, титаном и ниобием, азот, образуя нитриды, становится легирующим элементом, улучшающим структуру и механические свойства сплава. Медь улучшает металлическую основу чугуна.The increase in hardness of cast iron is achieved due to the complex effect of the components that make up its composition. Niobium strengthens the solid solution. In a chemically bound state with vanadium, titanium and niobium, nitrogen, forming nitrides, becomes an alloying element that improves the structure and mechanical properties of the alloy. Copper improves the metal base of cast iron.
Чугун выплавляют в вагранках, дуплекс-процессом или в электропечах и отливают в песчаные формы. Температура расплава при заливке литейных форм должна быть не ниже 1320°С. Отливки подвергают термообработке при температуре 450°С для снятия линейных напряжений.Cast iron is smelted in cupolas, a duplex process or in electric furnaces and cast in sand forms. The temperature of the melt when casting molds should be at least 1320 ° C. The castings are subjected to heat treatment at a temperature of 450 ° C to relieve linear stresses.
