Description
(54) СМЕСЬ ДЛЯ ДЕФОСФОРАШИ ЧУГУНА И СТАЛИ(54) MIXTURE FOR CAST DEFOSHORASH AND STEEL
ного металла. Добавка в смесь эвтектического карбида кальци и криолита за счет экзотермической реакции при их горении обеспечивает повышение температуры расплавленного металла и тем самым сохран ет температуру чугуна и стали, которую они имели до дефосфорации.low metal. The addition of a mixture of eutectic calcium carbide and cryolite due to the exothermic reaction during their combustion increases the temperature of the molten metal and thereby maintains the temperature of the iron and steel that they had before dephosphorization.
Осуществление экзотермической дефосфорации повышает эффективность процесса.The implementation of exothermic dephosphorization increases the efficiency of the process.
Смесь предложенного состава вл етс экономичной , так как можно использовать отходы эвтектического карбида кальци , примен емого при ваграночной плавке, а также сварочного карбида кальци , примен емого при производстве ацетилена, и использовать окись-закись железа, вл юш,иес отходами термообработки.The mixture of the proposed composition is economical, since it is possible to use waste of eutectic calcium carbide used in cupola melting, as well as welding calcium carbide used in the production of acetylene, and to use oxide-ferrous oxide, heat treatment waste.
Применение предложенной смеси значительно сокращает продолжительность обработкиThe use of the proposed mixture significantly reduces the processing time
жидкого чугуна и стали и не требует затрат на дополнительные устройства с помощью которых можно повышать температуру жидкого чугуна и стали.liquid iron and steel and does not require the cost of additional devices with which you can raise the temperature of liquid iron and steel.
