Description
Предлагаетс метод получени высококачественных жаропрочных легированных хромом чугунов в вагранке.A method is proposed for producing high-quality heat-resistant chromium-alloyed cast irons in a cupola.
Выплавка высокохромистого чугуна в насто щее врем производитс в электропечах или в вагранках, работающих на кислородном дутье.The smelting of high-chromium iron is currently being carried out in electric furnaces or in cupola furnaces operating on oxygen blast.
Необходимость выплавки этих чугунов в вагранках с применением кислородного дуть обусловливаетс чрезмерно высокой температурой плавлени хромистого чугуна.The need to smelt these cast irons in cupolas with the use of oxygen blowing is due to the excessively high melting temperature of chromium cast iron.
Предлагаемый метод получени жароупорного чугуна в вагранке состоит в замене феррохрома силикохромом, имеющим значительно более низкую температуру плавлени , что позвол ет вести выплавку этого чугуна в вагранке на нормальном воздушном дутье (без применени кислородного дуть ). Кроме того, замена фер|рохрома силикохромом позвол ет получать чугун с повышенным содержанием кремни (2-3,5%) при содержании хрома около 12-15% и, если это требуетс , с присадкою около 2-3% меди.The proposed method for producing heat-resistant cast iron in a cupola is to replace ferrochrome with a silicon-chromium having a significantly lower melting point, which allows this iron to be smelted in the cupola on a normal air blast (without using oxygen blowing). In addition, the replacement of ferrochromium by silicochrome makes it possible to produce cast iron with a high silicon content (2-3.5%) with a chromium content of about 12-15% and, if required, with an additive of about 2-3% copper.
Предмет изобретени Subject invention
Метод получени жароупорного чугуна в вагранке на обычном дутье, отличающийс применением в шихте вместо феррохрома силикохрома с содержанием кремни до 10%.The method of producing heat-resistant cast iron in a conventional blast cupola, which differs from using silicon-silicon up to 10% instead of ferrochrome.
