Claims (1)

Изобретение относится к металлургии, в частности к способу получения отливок из чугуна с высокой твердостью, которые могут использоваться в качестве быстроизнашивающихся деталей, например мелющих тел шаровых мельниц, сменных деталей горно-рудного и металлургического оборудования. Это достигается тем, что заливку жидкого чугуна производят в металлические формы при температуре 1220-1300oС при следующем соотношении компонентов, мас.%: углерод 2,8-3,8; сера до 0,12; кремний 0,5- 1,3; фосфор до 0,15; марганец 1,2-2,5; железо остальное. Использование заявленного способа обеспечивает получение отливок с высокой твердостью НВ 537 - НВ 558 и износостойкостью равномерно во всех частях их и с низкой их стоимостью.The invention relates to metallurgy, in particular to a method for producing castings of cast iron with high hardness, which can be used as wearing parts, for example grinding bodies of ball mills, replaceable parts for mining and metallurgical equipment. This is achieved by the fact that the pouring of molten iron is produced in metal forms at a temperature of 1220-1300 o With the following ratio of components, wt.%: Carbon 2.8-3.8; sulfur up to 0.12; silicon 0.5-1.3; phosphorus up to 0.15; manganese 1.2-2.5; iron the rest. Using the claimed method provides castings with high hardness HB 537 - HB 558 and wear resistance evenly in all parts of them and with their low cost.
