Description
Известен способ выплавки хромистых сталей в печах с кислой футеровкой с введением окислов хрома.There is a method of smelting chromium steels in acid lining furnaces with the introduction of chromium oxides.
Предлагаемый способ отличаетс тем, что дл улучшени использовани хрома и повышени качества хромистых сталей окислы хрома ввод т в печь по ходу выплавки вместе с кварцевым песком в соотношении, обеспечиваюндем основность шлака не более 0,65.The proposed method is characterized in that in order to improve the use of chromium and improve the quality of chromium steels, chromium oxides are introduced into the furnace during smelting together with quartz sand in a ratio that ensures basic slag not more than 0.65.
Предлагаемый способ осуществл етс следуюшим образом.The proposed method is carried out as follows.
Окислы хрома (руду или хромистый шлак) ввод т по ходу плавки совместно с кварцевым песком из расчета получени основности шлака не более 0,65. В результате этого степень усвоени хрома выплавл емой сталью достпгает 90%. Легирование хромом при указанных услови х кремневосстановительного процесса позвол ет выплавл ть хромистую сталь высокого качества, так как нет необходимости в раскислении стали алюминием.Chromium oxides (ore or chromic slag) are introduced in the course of smelting together with quartz sand at the rate of obtaining basic slag not more than 0.65. As a result, the degree of assimilation of chromium by the steel melted reaches 90%. Doping with chromium under these conditions of a silicon-reducing process makes it possible to melt high-quality chromium steel, since there is no need to deoxidize the steel with aluminum.
