Description

Значени  параметров окислительной продувки Скорость окислени  углерода также и-меет большое вли ние на степень удалени  азота. При скорости окислени  углерода менее 0,07 кг/т в минуту скорость поглощени  азота сталеплавильной ванной превалирует или равна скорости его выделени , и процесс деазотацнн не происходит. Кроме того, «в лое кипение затрудн ет протекание диффузионокислсии  углерода ciiuuie оЛо j;;; наб.подастс  весьма интенсивное металла, нри котором ногло; 1,еиие атмосферы через «ко)ольки мета зуюл ет иолучать желаемый эффект. Предлагаем1)1Й способ был опробован нри 11ро ;зводстие низколегироваиных сталей (08ХН2ГМТА, 08ХМФЛ и др.) в 5 т и 20 т дуговых электропечах. Углеродсодержащие матер -;алы з ко ичестве 6-12 кг/т ввод т в шихту. После расплавлени  завалкн начинают окисление углерода со скоростью 0,05- 0,20 кг/т в минуту. Далее нлавкн провод т в соответствии с прин той технологией. На онытных плавках, в которых скорость окислени  углерода находитс  в пределах 0,07- 0,15 кг/т в минуту, содержание азота в готовом металле не более 0,012%. Фор м у л а и 3 о б р е т е п и   Способ выплавки стали и сплавов, включаЮП1 .ИЙ введепие в металл углерода или углеродсодержан их материалов и последующее проведение окислительного периода, отлич а о щ и и с   тем, что, с целью получени  готового металла с минимальным содержанием азота, углерод ввод т из расчета получени  его в раснлаве перед началом окислительного пернода в количестве 6,0-12,0 уг/т, а затем его окисл ют со скоростью 0,07- 0,15 кг/т расплава в минуту.Values of Oxidative Purge Parameters The carbon oxidation rate also has a large effect on the degree of nitrogen removal. When the oxidation rate of carbon is less than 0.07 kg / t per minute, the rate of nitrogen absorption in the steelmaking bath prevails or is equal to the rate of its release, and the deazot process does not occur. In addition, "in the low boiling point, it is difficult for carbon diffusion acid to flow ciiuuie about j ;;; nab.podasts very intense metal nr which noglo; 1, Atmosphere of the atmosphere through the “skin” of meluses and get the desired effect. We propose 1) 1Y method was tested at 11ro; the production of low-alloy steels (08ХН2ГМТА, 08ХМФЛ, etc.) in 5 tons and 20 tons of electric arc furnaces. Carbonaceous materials - aly about 6–12 kg / ton are introduced into the charge. After melting, the start of oxidation of carbon at a rate of 0.05-0.20 kg / t per minute. The next steps are carried out in accordance with the technology adopted. In cold baths, in which the rate of oxidation of carbon is in the range of 0.07-0.15 kg / t per minute, the nitrogen content in the finished metal is not more than 0.012%. The form of the model and 3 about the bout e and Method of smelting steel and alloys, including SP1. The introduction of carbon into the metal or carbon-containing materials and the subsequent oxidation period, differs by the fact that the purpose of obtaining the finished metal with a minimum nitrogen content, carbon is introduced at the rate of its receipt in the melt before the start of the oxidative transfer in the amount of 6.0-12.0 coal / ton, and then it is oxidized at a rate of 0.07-0.15 kg / t melt per minute.
