Description

Известные способы очищени  жидкого чугуна от неметаллических включений посредством обработки его кальцинированной содой, поваренной солью, криолитом и другими веществами недостаточно эффективны ,  вл ютс  весьма громоздкими и усложн ют технологию г,роизводства .The known methods of cleaning liquid iron from non-metallic inclusions by treating it with soda ash, sodium chloride, cryolite and other substances are not sufficiently effective, are very cumbersome and complicate the r production technology.

Особенность насто щего изобретени  заключаетс  в том, что, с целью более полного очищени  чугуна от неметаллических включении с одновременным науглероживанием его, в ковщ с жидким чугуном ввод т магний с добавкой черного или серебристого графита.The peculiarity of the present invention is that, in order to more thoroughly clean the iron from non-metallic inclusions while simultaneously carburizing it, magnesium with the addition of black or silver graphite is introduced into the liquid iron sink.

Описываемый способ обработки жидкого чугуна заключаетс  в следующем. В ковщ совместно с магниевым зар дом ввод т в бумажной упаковке черный или серебристый графит в количестве 0,1-0,6% от веса металла. После такой комбинированной обработки за счет сильного барботажа чугун практически полностью очищаетс  от неметаллических включений, которые всплывают на поверхность металла в ковще и удал ротс  при разливке.The described method for treating molten iron is as follows. Black or silver graphite in the amount of 0.1-0.6% by weight of the metal is introduced into the paper bag together with the magnesium charge. After such a combined treatment, due to strong bubbling, the cast iron is almost completely cleaned of non-metallic inclusions, which float to the surface of the metal in the ladle and are removed during casting.

Способ очищени  металла от неметаллических включений одновременно сопровождаетс  регулируемым науглероживанием. Повыщенное содержание в жидком чугуне углорода также способствует всплываиию на поверхность металла соединений неметаллического происхождени .The method of cleaning metal from non-metallic inclusions is simultaneously accompanied by adjustable carburization. The increased content of carbon in liquid iron also contributes to the floating of non-metallic compounds on the metal surface.

Предмет изобретени Subject invention

Способ обработки жидкого чугуна, отличающийс  тем, что, с целью наиболее полного очищени  чугуна от неметаллических включений и науглероживани  его, расплавленный чугун обрабатывают в ковше магнием с добавкой черного или серебристого графита.A method of treating molten iron, characterized in that, in order to completely clean the iron from non-metallic inclusions and to carbonize it, the molten iron is treated in the ladle with magnesium with the addition of black or silver graphite.
