Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам чугуна, используемого в станкостроении, автомобилестроении.The invention relates to the field of ferrous metallurgy, in particular to the compositions of cast iron used in machine tools, automotive.
Известен чугун, содержащий, мас.%: углерод 2,5-4,0, кремний 0,8-2,5; марганец 0,3-1,5; медь 0-4,0; олово 0-0,5; кальций 0-0,2; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 2.5-4.0, silicon 0.8-2.5; manganese 0.3-1.5; copper 0-4.0; tin 0-0.5; calcium 0-0.2; iron - the rest [1].
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, кальций, железо, дополнительно содержит теллур, при следующем соотношении компонентов, мас.%: углерод 3,0-3,6; кремний 2,6-3,0; марганец 0,8-1,2; медь 1,8-2,2; олово 0,1-0,14; кальций 0,03-0,05; теллур 0,001-0,003; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, copper, tin, calcium, iron, additionally contains tellurium, in the following ratio of components, wt.%: Carbon 3.0-3.6; silicon 2.6-3.0; manganese 0.8-1.2; copper 1.8-2.2; tin 0.1-0.14; calcium 0.03-0.05; tellurium 0.001-0.003; iron is the rest.
В таблице приведены примеры составов чугуна.The table shows examples of cast iron compositions.
В составе чугуна компоненты проявляют себя следующим образом. Теллур стабилизирует карбиды. Медь повышает прочность и пластичность сплава. Олово способствует измельчению зерна. Кальций раскисляет чугун.In the composition of cast iron, the components manifest themselves as follows. Tellurium stabilizes carbides. Copper increases the strength and ductility of the alloy. Tin helps to chop grain. Calcium deoxidizes cast iron.
Чугун выплавляют в электропечах и отливают формы. Температура расплава при заливке литейных форм должна быть не ниже 1320°С. Отливки подвергают низкотемпературному отжигу при температуре 600°С для снятия линейных напряжений.Cast iron is smelted in electric furnaces and molds are cast. The temperature of the melt when casting molds should be at least 1320 ° C. The castings are subjected to low-temperature annealing at a temperature of 600 ° C to relieve linear stresses.
