Description
Продувка воздухом мартеновской ванны, в цел х ускорени окислени примесей и подогрева ванны за счет теплоты окислени примесей, вл етс нецелесообразной, так как сопровождаетс выплесками метал .la и шлака на стены и свод печи азотом, неосваиваемым ванной.Purging the open-air bath with air, in order to accelerate the oxidation of impurities and preheat the bath due to the heat of oxidation of impurities, is impractical because it is accompanied by splashes of metal and slag onto the walls and roof of the furnace with nitrogen that is not digested by the bath.
Согласно предложению, продувку мартеновской ванны производ т технически чистым кислородом посредством труб или фурм при полно.м или частичном устранении железной руды как при завалке, так и по ходу плавки.According to the proposal, the purging of the open-hearth bath is produced with technically pure oxygen by means of pipes or tuyeres, with full or partial elimination of iron ore, both during filling and during smelting.
При продувке мартеновской ванны кислородом выбросов не проис-ходит вследствие того, что при этом образуетс газа от окислени углерода , примерно, в о раз меньше, чем при продувке воздухом; вместе с тем при продувке кислородом тер етс соответственно меньше теплоты с отход п1,пми газами.When purging the open-hearth bath with oxygen, emissions do not occur due to the fact that this produces gas from the oxidation of carbon, about a factor of about less than when purging with air; at the same time, when purging with oxygen, respectively, less heat is lost from waste p1, pmi gases.

Способ производства стали к мартеновской печи, отл и ч а ющийс тем, что, в цел х ускорени окислени примесей ванны п нагрева её за счет теплоты окислени этих npHMeceii, ванну продувают н период окислени технически чистым кислородом посредством труб или фурм при полном или частичном устранении присадки железной руды в завалке и по ходу плавки.The method of steel production for the open-hearth furnace, which is the fact that, in order to accelerate the oxidation of impurities of the bath and its heating by the heat of oxidation of these npHMeceii, the bath is blown during the oxidation period with technically pure oxygen through pipes or tuyeres with complete or partial elimination iron ore additives in the filling and in the course of smelting.
