摘要
为降低低碳钢的冶炼成本,提高低碳钢冶炼质量,可通过优化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,减少钢水中Al2O3 夹杂的含量,提高钢水纯净度,降低吨钢成本;通过改变预抽模式,优化驱动气体的操作工艺,有效保护设备,降低维修成本,并为冶炼优质低碳钢水打下基础.
Abstract
In order to lower melting cost for low carbon steel,RH process parameters were optimized.Carbon oxygen reaction was fully utilized and carbon particles were added to remove partial free oxygen to substitute aluminum to deoxidize.The content of Al2O3 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.
