Изобретение относитс к области черной металлургии , конкретнее к способам выплавки стали в конвертерах.The invention relates to the field of ferrous metallurgy, and more specifically to methods for smelting steel in converters.
Известен способ выплавки стали в конвертере , включающий введение в конвертер железисто-известкового расплава непрерывно по ходу продувки.There is a method of steelmaking in the converter, including the introduction into the converter glandular lime melt continuously during the purge.
Недостатком такого способа вл етс раст нутый процесс шлакообразовани , что отрицательно сказываетс на рафинировании металла .The disadvantage of this method is the extended slagging process, which adversely affects the refining of the metal.
Целью изобретени вл етс ускорение шлакообразовани и улучшение рафинировани металла.The aim of the invention is to accelerate slagging and improve metal refining.
Поставленна цель достигаетс благодар тому, что по Предлагаемому способу железисто-известковый расплав ввод т в конвертер перед заливкой чугуна.The goal is achieved due to the fact that, according to the proposed method, the iron-lime melt is introduced into the converter before pouring the iron.
Предложенный способ осуш;ествл етс следуюш ,им образом.The proposed method of drying is described in the following manner.
В конвертер загружают скрап, заливают чугун и затем необходимое количество дл рафинировани металла железисто-известкового расплава, содержап,его, например, 50% окислов железа и оста.льное- окись кальци . После этого в конвертер заливают чугун и начинают продувку металла. Наличие в конвертерной ванне железисто-известкового расплава с самого начала продувки позвол ет сразу же интенсивно вести процессы десульфурации и дефосфорации металла, в результате чего достигаетс глубокое обессеривание и обесфосфоривалие стали. Вместе с тем продувку металла можно вести с высокой интенсивностью с начала подачи дуть , в результате чего сокращаетс продолжительность плавки.Scrap is loaded into the converter, cast iron is poured, and then the required amount for refining the iron-lime melt metal containing, for example, 50% iron oxides and residual calcium oxide. After that, cast iron is poured into the converter and metal purging is started. The presence of the iron-lime melt in the converter bath from the very beginning of the purging immediately leads to intensively the processes of desulfurization and dephosphorization of the metal, as a result of which deep desulfurization and the desphosphorisation of the steel are achieved. However, metal purging can be carried out with high intensity from the beginning of the supply of blowing, resulting in a shorter melting time.
Целесообразно заливать чугун с температурой 1200-1500°С. При температуре чугуна более 1500°С слив его должен производитьс осторожно, так как при этом могут быть выбросы металла из конвертера.It is advisable to cast iron with a temperature of 1200-1500 ° C. When the temperature of the cast iron is more than 1500 ° C, it should be drained carefully, since there may be metal emissions from the converter.
Предмет изобретени Subject invention
Способ выплавки стали в конвертере, включающий продувку металла окислителем, введением железисто-известкового расплава, о тличающийс тем, что, с целью ускорени шлакообразовани и улучшени рафинировани металла, железисто-известковый расплав ввод т в конвертер перед продувкой металла.A method of steel smelting in a converter, including blowing a metal with an oxidizing agent, introducing a lime-smelt melt, different from the fact that, in order to speed up slagging and improve the refining of the metal, the iron-lime smelt is introduced into the converter before blowing the metal.
