Description
HsoGpeTeiHie относитс к области черной металлургии, в частности к сталеплавильному производству, и может быть использовано при выплавке стали в подовых сталеплавильных печах и кислородных конверторах.HsoGpeTeiHie belongs to the field of ferrous metallurgy, in particular to steelmaking, and can be used in steelmaking in hearth steelmaking furnaces and oxygen converters.
Известна шлакообразующа смесь, состо ща из извести, глинозема и ферросилици . Смесь вводитс на дно ковша дл удалени из стали серы, неметаллических включений и кислорода.A known slag-forming mixture consisting of lime, alumina and ferrosilicon. The mixture is introduced to the bottom of the ladle to remove sulfur, non-metallic inclusions and oxygen from the steel.
Недостатком известной смеси вл етс значительное поглощение тепла при ноступлении в ковш первых порций металла, вследствие чего на дне ковша и его стенках образуетс скрап, преп тствующий нормальному проведению разливки металла и снижающий выход годных слитков.A disadvantage of the known mixture is a significant absorption of heat when the first portions of metal enter the ladle, as a result of which scrap is formed at the bottom of the bucket and its walls, which prevents normal metal casting and reduces the yield of ingots.
С целью предотвращени образовани скрапа в ковще при выпуске стали и улучшени процесса рафинировани в состав предложенной смеси введен коксик при следующем соотпошепии компонентов, вес. %:In order to prevent the formation of scrap in the ladle at the production of steel and to improve the refining process, a toxic mixture was added to the composition of the proposed mixture at the following components, weight. %:

В состав предложенной смеси дополнительно введены вещества, которые, раствор сь в металле, понижают температуру его нлавле1Н1Я (углерод и кре.мний). При этом полностью предотвращаетс переохлаждение первых порций металла, поступающих в ковщ, и образование скраиа на дне и стенках ковша. МеталлThe composition of the proposed mixture additionally introduced substances that, when dissolved in a metal, lower its temperature by HCl (carbon and silicon). At the same time, the overcooling of the first portions of the metal entering the ladle and the formation of scrai on the bottom and walls of the ladle are completely prevented. Metal

Перед выиуском плавки, например, из мартеновской печи на дно сталеразливочного ковHia , подготовленного к приему плавки, загружают предложенную щлакообразную смесь. Удельный расход смеси 8-12 кг/т стали. При выпуске стали первые ее порции взаимодействуют со смесью и температура плавлени металла резко понижаетс , что исключает образование скрапа. Одновременно образующийс при этом жидкий шлак вступает во взаимодействие с новыми порци ми мета.лла и рафинирует их. В результате металл очищаетс от серы и неметаллических включений.Before you melt, for example, from an open-hearth furnace, to the bottom of the casting kettle, prepared to receive the heat, load the proposed slag-like mixture. The specific consumption of the mixture is 8-12 kg / t of steel. With the release of steel, its first portions interact with the mixture and the melting point of the metal drops sharply, which eliminates the formation of scrap. At the same time, the molten slag formed during this process interacts with the new batches of meta.llas and refines them. As a result, the metal is cleared of sulfur and non-metallic inclusions.
Разливка металла протекает без осложиений.Metal casting proceeds without complications.
