Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам чугуна, используемого в станкостроении.The invention relates to the field of ferrous metallurgy, in particular to the compositions of cast iron used in machine tools.
Известен чугун, содержащий, мас.%: углерод 2,8-3,6; кремний 0,9-3,0; марганец 0,3-1,0; медь 0,8-1,2; олово 0,06-0,14; железо остальное [1]. Твердость такого чугуна составляет 187-207 НВ.Known cast iron, containing, wt.%: Carbon 2.8-3.6; silicon 0.9-3.0; manganese 0.3-1.0; copper 0.8-1.2; tin 0.06-0.14; iron the rest [1]. The hardness of such cast iron is 187-207 HB.
Задачей изобретения является повышение твердости чугуна.The objective of the invention is to increase the hardness of cast iron.
Технический результат достигается тем, что чугун, содержащий углерод, кремний, марганец, медь, олово, железо, дополнительно включает бор, калий и индий, при следующем соотношении компонентов, мас.%: углерод 3,0-3,6; кремний 2,6-3,0; марганец 0,8-1,2; медь 4,2-4,4; олово 0,1-0,14; бор 0,1-0,15; калий 0,001-0,002; индий 0,01-0,03; железо остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, copper, tin, iron, additionally includes boron, potassium and indium, with the following ratio of components, wt.%: Carbon 3.0-3.6; silicon 2.6-3.0; manganese 0.8-1.2; copper 4.2-4.4; tin 0.1-0.14; boron 0.1-0.15; potassium 0.001-0.002; indium 0.01-0.03; iron the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
В составе чугуна компоненты проявляют себя следующим образом. Бор стабилизирует карбиды. Месть повышает прочность и пластичность сплава. Олово, индий и калий способствуют измельчению зерна.In the composition of cast iron, the components manifest themselves as follows. Boron stabilizes carbides. Revenge increases the strength and ductility of the alloy. Tin, indium and potassium contribute to the grinding of grain.
Чугун выплавляют в вагранках дуплекс-процессом или в электропечах и отливают в песчаные формы. Отливки подвергают отжигу при температуре 500-550°С для снятия внутренних напряжений.Cast iron is smelted in cupolas by the duplex process or in electric furnaces and cast in sand forms. Castings are annealed at a temperature of 500-550 ° C to relieve internal stresses.
