介绍马钢120t转炉烟气分析动态控制炼钢技术的多功能应用:启用自学习,自适应功能,针对不同原材料条件,优化供氧造渣制度,实现全自动炼钢新模式;实践证明,本技术实施后,有效监控转炉底吹搅拌效果,w([C])×w([O])浓度积值在0.0012～0.0030占78.8%;利用烟气分析CO浓度变化趋势指导操作,降低喷溅率在4.0%以下;优化吹炼工艺,强化脱磷脱硫效果;准确预报钢水终点氧含量,提高脱氧合金化效果,降低吨钢成本5元;增加煤气回收量9m3/t钢和提高w(CO)5%～8%等显著成效。
Introduced the Masteel 120t converter flue gas analysis dynamic control of steel technology multi-functional applications: enable self-learning, adaptive function, according to different raw material conditions, optimize the oxygen slagging system, to achieve full automatic steelmaking new model; Practice has proved that the After the implementation of the technology, the effect of BOF blowing and mixing was effectively monitored. The product of w ([C]) × w ([O]) concentration accounted for 78.8% of 0.0012 ~ 0.0030. Using flue gas analysis of CO concentration trend to guide operation and reduce splashing Rate of less than 4.0%; optimize the blowing process, strengthen the dephosphorization desulfurization effect; accurate prediction of the oxygen content of the molten steel to improve the deoxidization alloying effect, reducing the cost of 5 tons of steel; increase gas recovery 9m3 / t steel and improve w (CO ) 5% to 8% and other significant results.
