Blow-in practice after overhaul of No.5 blast furnace in Dazhou Steel
In view of the water leakage problem in cooling wall of No.5 blast furnace in Dazhou Iron and Steel Co.Ltd.,which caused the blast furnace impossible to operate smoothly for a long time,the blast furnace was blown down for overhaul in December 2015 and blown in successfully in October 2016.The practice showed that it was a reasonable way of blow-in furnace to adjust matrix and develop the center air flow in the blast furnace until the air flow opened successfully,then gradually adjust the matrix again to develop the edge air flow,and at the same time,to add the blowing tuyere until the whole blowing operation.
