Description
новитс ниже 0,1% в час, а температура металла достигает 1640-1660°С.Novits below 0.1% per hour, and the temperature of the metal reaches 1640-1660 ° C.
Одновременно с началом кипени металла начинаетс раскисление шлака коксиком или другими углеродосодержащими материалами. Применение дру1гих раскислителей, способных загр знить металл жидкими или твердыми продуктами раскислени , не допускаетс .Simultaneously with the beginning of the boiling of the metal, the slag starts to be deoxidized by coking or other carbon-containing materials. The use of other deoxidizing agents capable of contaminating the metal with liquid or solid deoxidation products is not allowed.
Предлагаемый способ раскислени основной электростали обеспечивает быстрое снижение окисленности металла, так как кислород расходуетс па окисление углерода и одновременно адсорбируетс раскислительным шлаком, чему способствует перемешивание металла при этом способе. Наличие в этот момент в печи раскислительного шлака исключает поступление в металл дополнительного кислорода.The proposed method of deacidification of the main electro-metal ensures a rapid decrease in the oxidation of the metal, since oxygen is consumed in the oxidation of carbon and simultaneously adsorbed by a deoxidizing slag, which is promoted by the mixing of the metal in this method. The presence at this moment of deoxidizing slag in the furnace prevents the supply of additional oxygen to the metal.
Остальные технологические операции выплавки основной электростали (осаждаюш,ее раскисление, легирование, доводка по химическому составу и выпуск) производ тс обш;еприн тыми способами.The remaining technological operations for the smelting of the main electric steel (precipitating, deoxidizing, doping, finishing with chemical composition and output) are performed by conventional means.
Снижение температуры металла от 1640°- 16бб°С в начала бсаждаюш,его раскислени стали до температуры, необходимой дл каждой марки стали на разливке, достигаетс необходимым снижением нагрузки в течение остального времени плавки и выдержкой металла в разливочном кбвШе перед разливкой.Reducing the temperature of the metal from 1640 ° - 16bb ° C at the beginning of the bassadayus, its deoxidation of steel to the temperature required for each steel grade in the casting, is achieved by the necessary reduction of the load during the remaining melting time and holding the metal in the casting chamber before casting.
