Abstract
Description
Изобретение относится к области металлургии, а именно к составам хромистого чугуна, который может быть использован для изготовления прокатных валков, деталей мельниц и дробилок.The invention relates to the field of metallurgy, and in particular to compositions of chrome cast iron, which can be used for the manufacture of rolling rolls, parts of mills and crushers.
Известен чугун, содержащий, мас.%: углерод 1,7-3,8; кремний 0,01-2,5; марганец 0,01-1,0; хром 0,01-2,0; никель 0,01-5,0; ниобий 0,001-0,1; цирконий 0,01-0,3; бор 0,01-0,1; титан 0,01-0,15; теллур 0,001-0,05; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 1.7-3.8; silicon 0.01-2.5; manganese 0.01-1.0; chromium 0.01-2.0; nickel 0.01-5.0; niobium 0.001-0.1; zirconium 0.01-0.3; boron 0.01-0.1; titanium 0.01-0.15; tellurium 0.001-0.05; iron - the rest [1].
Задача изобретения состоит в повышении 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, хром, никель, ниобий, цирконий, бор, титан, теллур, железо, дополнительно включает азот, при следующем соотношении компонентов, мас.%: углерод 2,5-3,5; кремний 0,5-1,0; марганец 0,5-1,0; хром 15,0-20,0; никель 1,0-2,0; ниобий 1,0-1,5; цирконий 0,3-0,5; бор 0,05-0,1; титан 0,3-0,5; теллур 0,0005-0,001; азот 0,15-0,2; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, chromium, nickel, niobium, zirconium, boron, titanium, tellurium, iron, additionally includes nitrogen, in the following ratio, wt.%: Carbon 2.5-3 ,5; silicon 0.5-1.0; manganese 0.5-1.0; chrome 15.0-20.0; nickel 1.0-2.0; niobium 1.0-1.5; zirconium 0.3-0.5; boron 0.05-0.1; titanium 0.3-0.5; tellurium 0.0005-0.001; nitrogen 0.15-0.2; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
В составе чугуна компоненты проявляют себя следующим образом. Хром и марганец обеспечивают повышенную твердость чугуна. Никель и ниобий упрочняют твердый раствор. Бор и теллур стабилизируют карбиды. Цирконий и титан, который образует карбонитриды, способствуют повышению механических свойств чугуна и придают мелкозернистость его структуре.In the composition of cast iron, the components manifest themselves as follows. Chrome and manganese provide increased hardness of cast iron. Nickel and niobium harden the solid solution. Boron and tellurium stabilize carbides. Zirconium and titanium, which forms carbonitrides, contribute to the increase in the mechanical properties of cast iron and give a fine-grained structure.
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 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 550 ° C.
