Analysis and treatment of cooling accident of Xingang 7# blast furnace
During the period of Xingang 7# blast furnace is broken,the southwest thickness of the furnace wall col-lapses.In the air return process,the heat balance is destroyed by the thickness into the furnace cylinder,and the net coke amount is not enough,the tuyere is automatically blown open,and the sintering starting material with poor quality is used,finally causing the furnace temperature and cool.This paper analyzes the cause of the blast furnace cooling accident and the recovery to normal,which provides valuable experience for the rapid recovery of the blast furnace cooling accident.
