Description
Известен способ получени легированных металлов, заключающийс в том, что в одном агрегате получают сталь, вл ющуюс полупродуктом , а в другом выплавл ют легирующий сплав, после чего полученные расплавы сливают в ковщ и получают легированный сплав.A known method for producing doped metals consists in the fact that in one aggregate steel is obtained as an intermediate product, and in the other, an alloying alloy is smelted, after which the melts obtained are poured into a ladle and an alloy alloy is obtained.
Описываемый способ отличаетс от известного тем, что одновременно в одном агрегате выплавл ют раскисл ющий и легирующий сплав и синтетический щлак, переливаемый вместе со сплавом в разливочный ковщ дл обработки полупродукта при выпуске его в тот же ковщ.The described method differs from the known one in that at the same time a deoxidizing and alloying alloy and synthetic schlak are melted in one unit, poured together with the alloy into a casting dipper for processing the intermediate product when it is released into the same carpet.
Качество стали при этом повыщаетс .The quality of the steel increases.
Способ осуществл ют следующим образом. Полупродукт с низким содержанием фосфора , а если необходимо и легированный неокисл ющимис элементами, например никелем или медью, выплавл ют в мартеновской печи или в другом плавильном агрегате обычным способом. Полупродукт выпускают в ковщ по возможности без шлака. Жидкий сплав дл раскислени и легировани стали получают IB дуговой электропечи расплавлением щихты, состо щей из соответствующих ферросплавов, отходов сталей и сплавов. Одновременно с раскисл ющим и легирующим сплавом в той же электропечи приготовл ют синтетический шлак требуемого состава, обеспечивающий неизменность химического состава сплава. Приготовленный жидкий раскисл ющий и легирующий сплав с синтетическим шлаком сливают в струю выпускаемого в ковш полупродукта.The method is carried out as follows. The semi-product with a low content of phosphorus, and if necessary, doped with non-oxidizing elements, for example, nickel or copper, is melted in an open-hearth furnace or in another melting unit in the usual way. The semi-product is released into the ladle, if possible without slag. Liquid alloy for deoxidation and alloying of steel is obtained by IB electric arc furnaces by melting the pulping material consisting of appropriate ferroalloys, steel waste and alloys. Simultaneously with a deoxidizing and alloying alloy, synthetic slag of the required composition is prepared in the same electric furnace, ensuring the same chemical composition of the alloy. The prepared liquid deoxidizing and alloying alloy with synthetic slag is poured into the stream of the semi-product released into the bucket.
