Description
Известен способ раскислени малоуглеродистой стали в ковше ферромарганцем, феррованадием и силикомарганцем. Ферромарганец и феррованадий ввод т в металл соответственно в количествах 1,37 и 1,43 кг/г; 1,98 и 2,5 кг/г; 2,7 и 1,43 ка/г. Общее количество раскислителей составл ет 10-12 кг/т.There is a known method of deoxidizing low carbon steel in a ladle with ferromanganese, ferrovanadium and silicomanganese. Ferromanganese and ferrovanadium are introduced into the metal in amounts of 1.37 and 1.43 kg / g, respectively; 1.98 and 2.5 kg / g; 2.7 and 1.43 ka / g. The total amount of deoxidizers is 10-12 kg / ton.
Описываемый способ раскислени стали в ковше феррованадием и ферромарганцем состоит в том, что ферромарганец и феррованадий ввод т в металл одновременно в количестве 6-8 кг/г при отношении марганца к ванадию 2,8-3,8.The described method of deoxidizing steel in a ladle with ferrovanadium and ferromanganese is that ferromanganese and ferrovanadium are introduced into the metal simultaneously in an amount of 6-8 kg / g with a manganese-to-vanadium ratio of 2.8-3.8.
Это повышает качество стали.This improves the quality of the steel.
Наилучшим количественным сочетанием феррованади и электропечного ферромарганца при раскислении в ковше стали вл етс применение 1,5-2,3 кг/г феррованади и 3,5- 5 кг/г ферромарганца. Такое сочетание ферросплавов приводит к более полному удалению из стали неметаллических включений, увеличению выхода годного и повышению качества поверхности холоднокатаных листов.The best quantitative combination of ferrovanadium and electric furnace ferromanganese for deoxidation in a steel ladle is the use of 1.5-2.3 kg / g of ferrovanadium and 3.5-5 kg / g of ferromanganese. This combination of ferroalloys leads to a more complete removal of non-metallic inclusions from steel, an increase in the yield of good and an increase in the quality of the surface of cold-rolled sheets.
