Claims (1)

Способ производства литых низколегированных сталей с карбонитридным упрочнением, включающий выплавку стали в плавильном агрегате, ее раскисление, присадку карбамида, выпуск металла в сталеразливочный ковш, ввод в ковш алюминийсодержащих материаллов и ферротитана, заливку металла в формы, отличающийся тем, что присадку карбамида осуществляют в плавильный агрегат порциями по 0,05-0,20 кг/т в виде специальной лигатуры на основе измельченного стандартного ферросплава. A method of manufacturing cast low alloy steels with carbonitride hardening, including smelting steel in a smelting unit, its deoxidation, carbamide additive, metal pouring into a steel ladle, introduction of aluminum-containing materials and ferrotitanium into a ladle, metal casting into molds, characterized in that carbamide is added to the melting the unit in portions of 0.05-0.20 kg / t in the form of a special ligature based on crushed standard ferroalloy.
