本发明涉及一种转炉底吹元件的渣洗复通方法及维护方法,属于炼钢技术领域,解决了现有转炉底吹元件的渣洗复通速度慢的技术问题。本发明的转炉底吹元件的渣洗复通方法包括:预留上一炉次的热态炉渣,加入铁水;开启顶吹氧枪,控制压力及氧气流量,重复吹氧多次;开启并调节底吹元件的吹气流量;添加石灰冷却炉内炉渣,并将冷却后的炉渣和铁水的混合液倒掉;观察底吹元件是否复通,如果没有复通,重复上述步骤一至步骤四。本申请的转炉底吹元件的维护方法包括:炉底上涨出现堵塞倾向时,执行大流量模式;炉底下降导致底吹元件持续裸露时,执行小流量模式。本发明的转炉底吹元件的渣洗复通方法及维护方法能够实现转炉底吹元件的快速渣洗。
The invention relates to a slag washing and recanalization method of converter bottom blowing element and maintenance method, which belongs to the technical field of steelmaking and solves the technical problem of slow slag washing and recanalization speed of the existing converter bottom blowing element.The slag washing and recanalization method of the converter bottom blowing element of the invention includes: reserve the hot slag of the last furnace and add molten iron; open the top oxygen blowing gun, control the pressure and oxygen flow, and repeat oxygen blowing for many times; open and adjust the blowing flow of the bottom blowing element; add lime to cool the slag in the furnace, and pour out the mixture of cooled slag and molten iron; observe whether the bottom blowing element is recanalization. If not, repeat the above steps one to four. The maintenance method of the converter bottom blowing element of the application includes: when the furnace bottom rises and there is a blocking tendency, execute the large flow mode; when the bottom blowing element is continuously exposed due to the decline of furnace bottom, execute the small flow mode. The slag washing and recanalization method of the converter bottom blowing element and maintenance method of the invention can realize the rapid slag washing of the converter bottom blowing element.
