迁钢210t钢包全程加盖工艺及实践
|
摘要
迁钢二炼钢厂自投入使用210t钢包全程加盖技术及工艺后,取得了显著效果,平均出钢温度降低10℃,钢包热周转使用率长期保持在85%以上,取消了钢包在线烘烤,降低了煤气消耗,有效地保证了钢包洁净度,提高了钢包包衬寿命。实践生产运行表明,炼钢生产中钢包全程加盖工艺是一项节能、环保、降耗的先进技术,为迁钢二炼钢厂取得了显著的经济效益。但在一段时间内,该工艺运行稳定性较差,通过现场生产数据归纳分析,从中找出了影响钢包加、揭盖的因素,并制定了控制措施;同时,岗位要掌握其操作要点及主要设备,才能提高运行稳定性。
Remarkable results have been achieved since the whole covering technology and process of 210 tladle were put into operation in No.2 steelmaking plant of Qiansteel.The average tapping temperature has been reduced by10℃ and the utilization rate of turnover ladle has been kept above 85%for a long time.The on-line baking of ladle has been canceled,the gas consumption has been reduced,the cleanliness of ladle has been effectively guaranteed and the life of ladle lining has been increased.Practice showed that the whole ladle capping process was an advanced technology of energy saving,environmental protection and consumption reduction.Remarkable economic benefits have been obtained for the No.2 steelmaking of Qiansteel.However,in a period of time,the operation stability of the process was poor.Through the induction and analysis of the field production data,the factors affecting the addition and uncovering of the ladle were found out,and the control measures were formulated.At the same time,the working principle and main equipment must be mastered in order to improve the operation stability.
