Description
Известны способы обработки стали в ковше синтетическими известково-глиноземистыми шлаками или другими основными синтетическими шлаками, в которых содержание окиси железа или других окислителей не допускалось более 1 % от веса шлака.There are known methods for treating steel in a ladle with synthetic lime-alumina slags or other basic synthetic slags, in which the content of iron oxide or other oxidizing agents was not allowed to exceed 1% by weight of slag.
По предложенному способу одновременно с обработкой металла синтетическим шлаком присаживают в металл на струю окислители, например окалину, железную или марганцевую руду, в количестве до 0,5% от веса .металла .According to the proposed method, simultaneously with the processing of metal with synthetic slag, oxidants, for example, scale, iron or manganese ore, are deposited in the metal on a jet in an amount up to 0.5% by weight of the metal.
При выпуске металла из печи в ковш в последний заливают жидкий синтетический шлак, которым производитс рафинирование металла, а затем уже на струю выпускаемого металла присаживают окислители, например , окалину, л елезную или марганцевую руду и другие.When metal is released from the furnace, liquid synthetic slag is poured into the bucket in the latter, which is used to refine the metal, and then oxidants, for example, scale, lignite or manganese ore, and others are placed on the stream of metal produced.
Предмет изобретени Subject invention
Способ получени стали с рафинированием ее в ковше известково-глиноземистыми или другими основными синтетическими шлаками, отличающийс тем, что, с целью получени в жидком металле оптимального содержани кислорода и легкоплавких неметаллических включений, одновременно с обработкой металла синтетическим и:лаком присаживают в металл на струю окислители, например окалину , железную или марганцевую руду в количестве до 0,5% от веса металла.A method of producing steel with refining it in a ladle with lime-alumina or other basic synthetic slags, characterized in that, in order to obtain the optimum content of oxygen and low-melting non-metallic inclusions in the liquid metal, simultaneously with the processing of the metal with synthetic and: lacquer, oxidants are deposited into the metal on a jet , for example scale, iron or manganese ore in an amount up to 0.5% by weight of the metal.
