Padding method for air hole area of PS nickel converter

The invention provides a PS nickel converter air hole area filling method which comprises the following steps that (1) a gasket is arranged between a converter shell and an air hole brick, the gasket abuts against the inner wall of the converter shell, an oval hole is formed in the gasket, the hole corresponds to an air hole of the air hole brick, and a gap is formed between the gasket and the air hole brick; (2) an air pipe penetrates through the side wall of the furnace shell and is inserted into the air holes of the air hole bricks, and the air pipe passes through the holes; and (3) filler is added into the gaps, the filler is a mixture of magnesium powder and brine, and the mass percent of the magnesium powder to the brine is (5-6): 1. The air hole area filler falling caused by gaps and holes formed between the horizontal air pipe gasket and the furnace shell is effectively avoided, and it is prevented that after the air hole area is used in the later period, melt in gaps of air hole bricks directly flows
