To provide a horizontal converter, capable of increasing a unit ventilating amount without increasing the capacity of an existing fan in order to increase the capacity of production and capable of minimizing the dispersion of a furnace casing to the outside of the furnace through the opening of the furnace when the unit ventilating amount is increased.
Bricks of miscellaneous shapes 3a are lined so as to be thickened from the opening in the furnace of a tuyere 4 toward the opening in the furnace of the opening of the furnace 2 in order to make a radius (r1) from the axial center of the furnace casing to a refractory brick in the side of the tuyere 4 of the opening inside of the furnace 2 smaller than a radius (r2) from the tuyere 4 of the opening unit in the furnace of the opening of the furnace 2 to a refractory brick at the opposite side of the tuyere 4. Further, the thickness of refractory bricks on the bottom of the furnace, which are apart from the inside opening unit of the tuyere 4, is thinned to line them together with or different from the thickened bricks.
