研究了电炉吹氧冶炼氧化期的熔池反应。观察到:在良好的操作情况下,吹氧冶炼的脱碳速度可以达到0.015—0.020%C/分钟(矿石冶炼的只有0.005%C/分钟左右);吹氧过程中,(FeO)和[O]显著降低并与[C]趋近平衡,[O]的减少量与脱碳速度间有直线关系。并注意到吹氧冶炼氧化期脱磷效果较差,平均脱磷量仅为0.004%左右;采用熔化期脱磷操作后,氧化期末[P]可以降低到小于0.015%。至于吹氧冶炼的脱磷过程,目前还不完全了解。
The reaction of molten bath in the oxidation stage of oxygen blowing in EAF was studied. It has been observed that under good operating conditions, the rate of decarburization can be 0.015-0.020% C / min for oxygen blowing (only 0.005% C / min for ore smelting); in the oxygen blowing process, (FeO) and [O ] Was significantly reduced and approached [C], and there was a linear relationship between the reduction in [O] and decarburization rate. It was also noted that the oxygen dephosphorization in the oxygen blowing smelting was less effective and the average amount of dephosphorization was only 0.004%. After the dephosphorization operation in the melting phase, the final oxidation period [P] could be reduced to less than 0.015%. As for the oxygen blowing oxygen blowing process, is not yet fully understood.
