本发明涉及转炉冶炼技术领域,尤其涉及一种促进转炉反应平衡的方法,所述方法包括:在顶底复吹转炉的吹炼终点,测量获得转炉终点碳含量和转炉终点氧含量;根据所述转炉终点碳含量和所述转炉终点氧含量,调整所述顶底复吹转炉的底吹氩气时间和底吹氩气流量;在所述顶底复吹转炉底吹结束后,出钢。本发明通过在顶底复吹转炉的吹炼终点获得转炉终点的碳含量和氧含量,接着根据转炉终点的碳含量和氧含量,对顶底复吹转炉的底吹氩气时间和底吹氩气流量进行调整,通过上述方式能够促进钢渣反应平衡,减少了钢水中磷含量和氧含量超标的风险,有利于提高产品质量。
The invention relates to the field of converter smelting technology, especially to a method to promote the reaction balance of converter. The method includes: measuring the carbon content and oxygen content at the endpoint of the top and bottom combined blowing converter; the bottom blowing argon time and flow rate of the top-bottom combined blowing converter are adjusted according to the endpoint carbon content and the endpoint oxygen content of the converter; after the bottom blowing of the top-bottom combined blowing converter is completed, the steel is discharged. The present invention obtains the carbon content and oxygen content at the end of the converter through the blowing end of the top-bottom combined blowing converter. Then, according to the carbon content and oxygen content at the end of the converter, the bottom argon blowing time and bottom argon blowing flow rate of the top-bottom combined blowing converter are adjusted. Through the above methods, the reaction balance of steel slag can be promoted, the risk of excessive phosphorus content and oxygen content in molten steel can be reduced, and the product quality can be improved.
