Abstract
Description
Изобретение относится к области металлургии, в частности к составам чугуна, который может быль использован для изготовления прокатных валков.The invention relates to the field of metallurgy, in particular to compositions of cast iron, which could be used for the manufacture of rolling rolls.
Известен чугун, содержащий, мас.%: углерод 2,5-4,0; кремний 0,8-2,5; марганец 0,3-1,5; хром 0-1,5; алюминий 0-0,2; цирконий 0-1,0; бор 0-1,0; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 2.5-4.0; silicon 0.8-2.5; manganese 0.3-1.5; chrome 0-1.5; aluminum 0-0.2; zirconium 0-1.0; boron 0-1.0; iron - the rest [1].
Задача изобретения состоит в повышении прочности чугуна.The objective of the invention is to increase the strength of cast iron.
Технический результат достигается тем, что в чугуне, содержащем углерод, кремний, марганец, хром, алюминий, цирконий, бор, железо, компоненты находятся при следующем соотношении, мас.%: углерод 2,2-2,6; кремний 2,2-2,6; марганец 0,8-1,2; хром 4,0-5,0; алюминий 0,4-0,8; цирконий 0,2-0,4; бор 0,08-0,12; железо - остальное.The technical result is achieved in that in cast iron containing carbon, silicon, manganese, chromium, aluminum, zirconium, boron, iron, the components are in the following ratio, wt.%: Carbon 2.2-2.6; silicon 2.2-2.6; manganese 0.8-1.2; chrome 4.0-5.0; aluminum 0.4-0.8; zirconium 0.2-0.4; boron 0.08-0.12; iron is the rest.
В таблице приведены составы чугунаThe table shows the composition of cast iron
Присутствующие в составе чугуна компоненты проявляют себя следующим образом. Хром обеспечивает твердость и теплостойкость чугуна. Алюминий препятствует росту окалины. Бор придает мелкозернистость структуре сплава. Цирконий упрочняет границы зерен.The components present in the composition of cast iron manifest themselves as follows. Chrome provides hardness and heat resistance of cast iron. Aluminum inhibits the growth of scale. Boron gives a fine-grained alloy structure. Zirconium strengthens grain boundaries.
Чугун выплавляют в вагранках дуплекс-процессом или в электропечах и отливают 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 cupolas by the duplex process or in electric furnaces and cast into hot (400-450 ° C) metal molds coated with refractory clay. To relieve internal stresses, castings are annealed at a temperature of 550 ° C.
