Description
Изобретение относитс к электрометаллургии стали, в частности к выплавке стали в дуговых электропечах . Известны спсэсобы ведени плавки в дуговой сталеплавильной печи с исполь зоаанием устройства электромагнитного перемешивани (ЭМП) в различные пери оды плавки с целью усреднени химсос- таза металла и снижени температурного градиента по объему ванны 1 и В известных способах устройство ЭМП работает в периоды легировани и доводки металла, и служит дл ycKopieни растворени добавок и протекани металлургических реакций. Скорость перемешивани металла определ етс стойкостыо огнеупорной футеровки,: о разрушении которой косвенно можно судить по росту содержани MgO в шлаке . Наиболее близким по технической сущности и достигаемым, результатам К Изобретению вл етс способ ведени плавки в дуговой сталеплавильной печи, включающий период расплав 1ени и период рафинировани с использова нием в последнем устройства электромагнитного перемешивани ЗЗ Однако-отсутствие перемешивани металла в период-проплавлени колодцев зат гивает растворение твердого скрепа в расплавленной стали. Жидкий металл прогреваетс только сверху дугами , нижние слои, в которые погружен куски нерасплавившегос скрапа, остаютс холодными и медленно раствор ют твердый металл. Цель изобретени - сокращение длительности периода расплавлени . Цель достигаетс тем, что согласно способу ведени плавки в дуговой- сталеплавильной печи, включающему период расплавлени и период рафинировани с использованием в последнем устройства электромагнитного перемешивани , перемешивающее устройство включаютThis invention relates to steel electrometallurgy, in particular to steel smelting in electric arc furnaces. Known procedures for smelting in an electric arc furnace with the use of an electromagnetic stirring device (EMI) during different periods of melting in order to average the chemical mixture of the metal and reduce the temperature gradient over the volume of the bath 1 and In the known methods, the EMI device works during periods of metal alloying , and serves to dissolve additives and conduct metallurgical reactions. The stirring rate of the metal is determined by the resistance of the refractory lining, the destruction of which can be indirectly judged by the increase in the MgO content in the slag. The closest in technical essence and achievable results To the Invention is a method of conducting smelting in an electric steel-smelting furnace, including the melt period 1 and the refining period using the electromagnetic mixing device ZZ in the latter However, the absence of metal mixing during the period of melting of wells tightens solid brace in molten steel. The liquid metal is heated only by the arcs from above, the lower layers, in which pieces of unmelted scrap are submerged, remain cold and the solid metal slowly dissolves. The purpose of the invention is to reduce the duration of the melting period. The goal is achieved by the fact that, according to the method of smelting in an arc-steel-smelting furnace, including a melting period and a refining period using an electromagnetic stirring device in the latter, the mixing device includes
