Abstract

Изобретението се отнася до десулфурираща смес в прахообразна форма за обработване на стопен чугун чрез инжектиране. Сместа подобрява десулфурирането.Тя включва в тегл.% повече от 50 технически калциев карбид и/или вар и в даден случай магнезий до 40, алуминий до 20 и други добавки като въглеродсъдържащи продукти и/или покриващи средства общо в количество, не повече от 10%. Десулфуриращата смес съдържа и сяра между 1 и 3,5% тегловни.The invention relates to a powdered desulphurising mixture for the treatment of molten cast iron by injection. The mixture improves the desulfurization. It comprises more than 50% technical calcium carbide and / or lime and optionally magnesium up to 40, aluminum up to 20 and other additives such as carbonaceous products and / or coating agents in total amount of not more than 10 %. The desulfurization mixture also contains sulfur between 1 and 3.5% by weight.
