摘要
为降低低碳钢的冶炼成本,通过优化RH工艺参数,充分利用碳氧反应,加入碳粒,去除部分游离氧以代替铝脱氧,减少了钢水中Al2O3夹杂的含量,提高了钢水纯净度,降低了吨钢成本;通过改变预抽模式,优化驱动气体的操作工艺,减少喷溅,有效保护了设备,降低了维修成本。
In order to lower melting cost for low carbon steel, RH process parameters were optimized. Car- bon oxygen reaction was fully utilized and carbon particles were added to remove partial free oxygen to sub- stitute aluminum to deoxidize. The content of Al？O？ inclusion was reduced and steel cleanliness improved, reducing tonnage steel cost. Through changing pre-vacuuming style and optimizing the operation process of driving gas, splashing was curbed and equipment effectively protected, reducing maintenance cost
