The converter is a vertical cylindrical smelting furnace that does not require an external heating source and mainly uses liquid pig iron as raw material for steelmaking. According to the nature of refractory lining, it can be divided into two types: acid converter and alkaline converter. According to the position where the gas is blown into the furnace, it is divided into bottom blowing, top blowing, side blowing and top and bottom combined blowing converters. The bottom blowing, top-bottom composite blowing converter furnace bottom is designed with breathable bricks. When laying, the position of the breathable bricks needs to be positioned. The bottom of the top-blowing and side-blowing converters is not designed with ventilated bricks, and the bottom masonry is relatively simple.
