Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам антифрикционных чугунов, которые могут быть использованы для изготовления изделий, работающих в условиях трения и износаThe invention relates to the field of ferrous metallurgy, in particular to compositions of antifriction cast irons, which can be used for the manufacture of products operating in conditions of friction and wear
Известен чугун, содержащий, мас.%: углерод 3,5-4,0; кремний 2,5-3,5; марганец 8,0-12,0; олово 0,5-1,0; медь 0,2-0,7; железо - остальное [1]. Твердость такого чугуна составляет 225-240 НВ.Known cast iron, containing, wt.%: Carbon 3,5-4,0; silicon 2.5-3.5; manganese 8.0-12.0; tin 0.5-1.0; copper 0.2-0.7; iron - the rest [1]. The hardness of such cast iron is 225-240 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, олово, медь, железо, дополнительно содержит вольфрам, хром и титан при следующем соотношении компонентов, мас.%: углерод 3,5-4,5; кремний 2,5-3,5; марганец 8,0-12,0; олово 0,05-0,1; медь 0,2-0,7; вольфрам 1,5-2,5; хром 4,0-5,0; титан 0,5-1,0; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, tin, copper, iron, additionally contains tungsten, chromium and titanium in the following ratio of components, wt.%: Carbon 3,5-4,5; silicon 2.5-3.5; manganese 8.0-12.0; tin 0.05-0.1; copper 0.2-0.7; tungsten 1.5-2.5; chrome 4.0-5.0; titanium 0.5-1.0; iron is the rest.
В таблице приведены составы чугунаThe table shows the composition of cast iron
В составе чугуна компоненты проявляют себя следующим образом. Марганец повышает склонность чугуна к карбидообразованию, однако кремний и титан снижают устойчивость первичных карбидов. Хром стабилизирует карбиды. Вольфрам упрочняет твердый раствор. Медь и олово улучшают металлическую основу сплаваIn the composition of cast iron, the components manifest themselves as follows. Manganese increases the tendency of cast iron to carbide formation, however, silicon and titanium reduce the stability of primary carbides. Chrome stabilizes carbides. Tungsten strengthens the solid solution. Copper and tin improve the metal base of the alloy
Чугун выплавляют в вагранках, дуплекс-процессом или в электропечах и отливают центробежным способом в горячие (400-450°С) металлические формы, обмазанные огнеупорной глиной. Для снятия внутренних напряжений отливки отжигают при температуре 500-550°С.Cast iron is smelted in cupola furnaces, by a duplex process or in electric furnaces, and centrifugally cast in hot (400-450 ° C) metal molds coated with refractory clay. To relieve internal stresses, castings are annealed at a temperature of 500-550 ° C.
