Description

(54) СПОСОБ ПРОИЗВОДСТВА КОНВЕРТЕРНОЙ СТАЛИ По окончании продувки готовый еталл и часть шлака (до 5%) дл  покрыти  зеркала металла сливают в сталеразливочный ковш. Устанавливают конвертер в вертикальное положение. В оставшийс  шлак дают 20-25% извести от полного количества на плавку, после чего производ т завалку лома, заливку чугуна и ведут продувку ванны кислородом в течение 15-25% времени всего периода продувки плавки. В момент начал-1 интенсивного окислени  углерода про.иу; ку прекращают и сливаю 7О-8О% шлдка. После слива шлака продув ку продолжают, причем в начале второго периода продувки присаживают 5О-6О% ко- личества извести, необходимого на плавку 03 Ф о и 3 о б р м у л а р е т е н и   Способ производства конвертерной стали, включающий использование конечного шлака лредыдуией плавки конвертера в последующей плавке с присадкой извести, отличающийс  тем, что, с целью эффективного использовани  рафинирующей способности конечного шлака и увеличени  выхода годного, перед продувкой очередной плавки в конвертере оставл ют 9О-95% конечного шлака предыдущей плавки и с ним производ т продувку металла в течение 15-25% времени всего пери да продувки, после чего 7О8О% шлака сливают и в начале второго периода продувки присаживают 5О-6О% извести, необходимой на плавку.(54) METHOD OF CONVERTER STEEL PRODUCTION At the end of the purge, the finished metal and a portion of the slag (up to 5%) to cover the metal mirror are poured into the casting ladle. Install the converter in a vertical position. In the remaining slag, 20–25% of lime from the total quantity of smelting is given, after which the scrap is filled, the pig iron is poured and the bath is purged with oxygen for 15–25% of the entire period of the melt blow. At the time of the start-1 of the intense oxidation of pro.iu carbon; ku stop and drain the 7O-8O% Shldka. After the slag is discharged, the blowdown is continued, and at the beginning of the second period of the blowdown, 5O-6O% of the amount of lime required for smelting 03 F o and 3 o bm u r e et e and the production method of converter steel, including use of the final slag before the smelting of the converter in the subsequent smelting with lime additive, characterized in that, in order to effectively use the refining capacity of the final slag and increase the yield of the suitable, before heating the next smelting in the converter, 9O-95% of the final slag of the previous one is left the metal is blown through with the smelting and with it for 15-25% of the entire period of the purge, after which the OO8% of the slag is drained and, at the beginning of the second period of the purge, 5O-6O% of the lime required for smelting is sown.
