Изобретение относитс к области черной металлургии и может быть использовано при рафинировании и науглероживании чугуна.The invention relates to the field of ferrous metallurgy and can be used in the refining and carburizing of cast iron.
Известна смесь дл десульфурации и науглероживани чугуна, содержаща карбид кальци , фтористую соль и графит.A known mixture for desulfurizing and carburizing cast iron containing calcium carbide, fluoride salt and graphite.
С целью повышени эффективности процесса деоул фурации и науглероживани чугуна в сосгав смеси предлагаетс вводить криолит и хлористый натрий при следующем соотношении компонентов, вес. %:In order to increase the efficiency of the deole process and the carburizing of cast iron, it is proposed to introduce cryolite and sodium chloride into the mixture in the mixture in the following ratio of components, wt. %:
Карбид кальци 52-70Calcium carbide 52-70
Графит8-16Graphite8-16
Криолит8-12Cryolite8-12
Хлористый натрий10-24,Sodium Chloride 10-24,
что повышает эффективность обработки чугуна .which increases the processing efficiency of cast iron.
Например, после обработки чугуна предлагаемой смесью содержание серы в чугуне составл ет 0,007% и углерода - 3,1%.For example, after the iron has been treated with the proposed mixture, the sulfur content in the iron is 0.007% and carbon - 3.1%.
