摘要
阐述了莱钢120t复吹转炉利用音频化渣技术研究在线控制炉渣技术的效果。综合分析了音频曲线变化趋势及其变化率所反映出的炉内化渣情况,通过研究音频化渣历史曲线在线控制炉内化渣情况,优化了过程操作模式,降低了返干、喷溅率,保证了炼钢过程全程化渣以及良好的脱磷率,降低了石灰消耗。进一步提高自动炼钢的过程控制水平和终点控制水平。
Describes the Laiwu 120t bof-lbe using audio frequency slag technology research online control technology of slag effect. Comprehensive analysis of the audio curve and its rate of change are reflected in the furnace internalization slag. Through the research of audio frequency slag history curve control furnace slag internalization and optimize the process operation mode, the returning dry and spray rate is reduced, ensure the steelmaking process of slag and good dephosphorization rate, reduce the consumption of lime. To further improve the level of automatic steeXmaking process control and terminal control level.
