PURPOSE:To provide a titled device which dries and heats efficiently a pan for metallurgy by providing a combustion gas guiding cylinder which sags to enclose a heating burner attached to a cover body imposed on the upper part of the pan and guiding the combustion gas to the bottom of the pan. CONSTITUTION:The heating burner is provided to the bottom surface at the center of the cover body 1 of a heater (p) closing the upper part of the metallugical pan (q) to burn the combustion gas supplied through a fuel supply pipe 5a and an air supply pipe 5b for combustion. The generated combustion gas is guided to the bottom of the pan mouth by the combustion gas guiding cylinder 3 provided to enclose the burner 2 and to sag from the body 1. The above- mentioned combustion gas rises after heating the castable refractories 9, corner bricks 10, etc. in the bottom of the pan and heats directly a shell 6 and the castable refractory lining 8 provided in the inside wall 7 of refractory bricks. The gas heats also the cylinder 3 to generate radiation heat and to accelerate the heating in the pan. The gas is thereafter discharged through a waste combustion gas port 4 of the body 1. |
