Description
Изобретение относитс к области черно металлургии, в частности к получению стали в конверторе.The invention relates to the field of ferrous metallurgy, in particular to the production of steel in the converter.
Известен способ продувки чугуна снизу вверх с помощью кислорода или воздуха, обогащенного кислородом.There is a method of blowing iron from the bottom up using oxygen or air enriched with oxygen.
Предлагаемый способ отличаетс т-ем, что продувка осуществл етс кислородом с добавлением нейтрального или окисл ющего газа под давлением, превышающим 8 атм. Такое выполнение продувки снижает потери железа во врем продувки и, вследствие этого, повышает выход годного металла.The proposed method differs in that the purge is carried out with oxygen with the addition of a neutral or oxidizing gas under pressure exceeding 8 atm. This embodiment of purging reduces iron loss during purging and, as a result, increases the yield of the metal.
Предложенный способ реализуетс следующим образом.The proposed method is implemented as follows.
Необходимое дл рафинировани чугуна количество кислорода, в виде чистого кислорода с возможным дооавлением нейтрального или окисл ющего газа, вводитс через днище, снабженное равномерно распределенными соплами, внутренний диаметр которых меньше 8 мм, изготовленными из огнеупорного материала высокого качества. Давление продувки , измеренное в нижней части днища, превышает 8 агм.The amount of oxygen required for refining pig iron, in the form of pure oxygen with possible addition of neutral or oxidizing gas, is introduced through the bottom, equipped with evenly distributed nozzles, the inner diameter of which is less than 8 mm, made of high quality refractory material. The purge pressure measured at the bottom of the bottom is greater than 8 agm.
Предмет изобретени Subject invention
Способ продувки чугуна киcлopoдo i снизу, отличающийс тем, что, с целью снижени угара железа, продувку ведут кислородом в смеси с окисл ющим или иейтралы ым газом при давлении дуть более 8 ат..1г.The method of purging the iron with oxygen i from the bottom, characterized in that, in order to reduce iron loss, purging is carried out with oxygen mixed with oxidizing or neutral gas with a pressure to blow more than 8 at .1 g.
