Description
Изобретение относитс к металлургической промышленности.The invention relates to the metallurgical industry.
Известны способы обработки стали, при которых перемешивание металла лри обработке жидкими шлаками или твердыми шлакообразующими смес ми осуществл етс путем увеличени высоты падени струи металла, перелива из одного ковша в другой или продувки газами.There are known methods for treating steel in which the mixing of metal by treatment with liquid slags or solid slag-forming mixtures is carried out by increasing the height of the fall of the metal stream, overflowing from one ladle to another, or purging with gases.
Недостатками указанных способов вл ютс сильное охлаждение металла, а также сложность и высокие эксплуатационные расходы .The disadvantages of these methods are the strong cooling of the metal, as well as the complexity and high operating costs.
Дл наиболее полного использовани реагентов и интенсификации процесса предлагаетс при выпуске металла из печи в ковш с жидким шлаком вводить в сталь твердые карбоциклические вещества в количестве 0,5- 1 кг/т стали. Твердые карбоциклические вещества ввод т в сталь одновременно с твердой шлакообразующей смесью, содержащей окись кальци , фтористый кальций и силикокальции , присаживаемой в количестве 5- 6 кг/т стали.To make the most complete use of the reagents and intensify the process, it is proposed that solid carbocyclic substances in the amount of 0.5-1 kg / ton of steel be introduced into the steel in the ladle with liquid slag when the metal is released from the furnace. Solid carbocyclic substances are introduced into the steel simultaneously with a solid slag-forming mixture containing calcium oxide, calcium fluoride and silicocalcium, set down in the amount of 5-6 kg / ton of steel.
Под действием выдел ющихс паров и газов металл в ковше энергично перемешиваетс с жидким синтетическим шлаком или твердой шлакообразующей смесью и рафинируетс .Under the action of released vapors and gases, the metal in the ladle is vigorously mixed with the liquid synthetic slag or solid slag-forming mixture and refined.
