Abstract
Способ производства автоматной стали, включающий выплавку полупродукта в сталеплавильном агрегате, отличающийся тем, что проводят внепечную обработку металла на установке «Ковш-Печь» с дополнительным введением висмута при загущении шлака магнезитовым порошком, разливку на МНЛЗ способом «под уровень» при высоком содержании серы для получения стали в виде непрерывнолитой заготовки следующего состава, в мас.%: ! углерод не более 0,16 кремний не более 0,35 марганец 1,0-1,5 сера 0,08-0,35 фосфор 0,06-0,15 алюминий не более 0,03 висмут 0,06-0,12 железо и примеси остальное A method for the production of automatic steel, including the smelting of a semi-product in a steel-smelting unit, characterized in that out-of-furnace processing of the metal is carried out at the Ladle-Furnace installation with the addition of bismuth when the slag is thickened with magnesite powder, casting at the continuous casting machine at a level with high sulfur content for for producing steel in the form of a continuously cast billet of the following composition, in wt.%:! carbon no more than 0.16 silicon no more than 0.35 manganese 1.0-1.5 sulfur 0.08-0.35 phosphorus 0.06-0.15 aluminum no more than 0.03 bismuth 0.06-0.12 iron and impurities rest
