HEATING EQUIPMENT FOR WALL LINING OF METALLURGICAL PAN

PURPOSE:To provide the titled equipment heating and drying efficiently and economically the wall lining of a metallurgical pan by constituting in such a manner that the lining of said pan is heated directly with the burning of a gas for burning preheated by a combustion gas with a burner and further the heating is promoted with the radiant heat transmitted by heating a gas permeable heat resistant plate. CONSTITUTION:A heating equipment A consisting of a burner 3, etc. for heating which is fitted downward to the upper and lower gas permeable heat resisting plates 2a, b and the lower part gas permeable heat resisting plate 2a which divide a cylindrical main body 1 and space S, is positioned on the upper end of the mouth of pan, after the wall lining 11 of castable refractory material being made on the pan mouth having a shell 9 and firebrick inner wall 10. A gas for burning to be introduced from gas feeding pipes 4a, b for heating is fed to a heating burner 3 via pipings 41a, b provided in bending for heat exchange inside said space S and is burnt. The combustion gas dries the lining 11 with its direct heating and further promotes the heating inside the pan mouth by radiant heat by heating the gas permeable heat resisting plates 2A, B in case of its being discharged after passing through these plates, and yet elevates a thermal efficiency by preheating the gas for burning of the inside of pipings 41a, b.
