Description
Изобретение относитс к металлургии и предназначено дл использовани при выплавке среднелегированной стали.This invention relates to metallurgy and is intended for use in the smelting of medium alloyed steel.
Известен способ раскислени стали ферромарганцем , ферросилицием, алюминием и ферротитаном. Указанный способ раскислени не обеспечивает требований прочностных свойств.There is a known method of deoxidizing steel with ferromanganese, ferrosilicon, aluminum and ferrotitanium. This method of deoxidation does not provide the requirements of strength properties.
Целью изобретени вл етс повышение предела текучести, предела прочности и хладностойкости стали при сохранении относительного удлинени на требуемом уровне. Эта цель достигаетс тем, что дл раскислени стали совместно с алюминием дополнительно ввод т феррованадий в количестве 1,5- 2,5 кг/г и силикокальций в количестве 1,5- 3,0 кг1т или феррованадий, силикокальций и ферробор в количестве 100-325 г/г. Ферромарганец и ферросилиций при этом примен ют в обычном пор дке.The aim of the invention is to increase the yield strength, strength and cold resistance of steel while maintaining the relative elongation at the desired level. This goal is achieved by the addition of ferrovanadium in the amount of 1.5-2.5 kg / g and silicocalcium in the amount of 1.5-3.0 kg1t or ferrovanadium, silicocalcium and ferroboron in the amount of 100- 325 g / g. Ferromanganese and ferrosilicon are used in the usual manner.
Листы из стали, раскисленной по предлагаемому способу, имеют более высокие прочностные свойства при достаточно высоком уровне пластических свойств, чем листы из стали, раскисленной по известному способу.Sheets of steel, deoxidized by the proposed method, have higher strength properties with a sufficiently high level of plastic properties than sheets of steel, deoxidized by a known method.
Раскисление стали по предлагаемому способу позволит также уменьшить загр зненность металла неметаллическими включени ми , раздробить и уменьшить прот женность сульфидных и оксидных включений.The deacidification of the steel by the proposed method will also reduce the contamination of the metal with nonmetallic inclusions, crush and reduce the extent of sulphide and oxide inclusions.
Предлагаемый способ раскислени следует примен ть в случае необходимости получени стали с повышенными прочностными свойствами и хладностойкостью.The proposed method of deoxidation should be applied, if necessary, to obtain steel with enhanced strength properties and cold resistance.
Предмет изобретени Subject invention
Способ раскислени среднелегированной стали марганцем, кремнием, алюминием, отличающийс тем, что, с целью повышени механических свойств и хладностойкости, совместно с алюминием в нее ввод т 1,5-3,0 кг силикокальци , 1,5-2,5 кг феррованади , 100-325 г ферробора на тонну металла.The method of deoxidizing steel with manganese, silicon, aluminum, characterized in that, in order to improve the mechanical properties and cold resistance, 1.5-3.0 kg of silicocalcium, 1.5-2.5 kg of ferrovanadium are introduced with it, 100-325 g ferroboron per ton of metal.
