摘要： PROBLEM TO BE SOLVED: To obtain a reduction melting method, by which the obtd. reduced material has excellent product quality and the operation is easily and quickly executed. SOLUTION: A packing layer 7 is formed in a furnace and also, treating objective material is charged into the packing layer 7 under keeping to high temp. reducing condition. In the case of obtaining the reduction melting material by reduction-melting the treating objective material in the packing layer, a reduction melting furnace constituted as formable to a combustion chamber 3 fitting a burner 8 adjustable to air fuel ratio at the lower part of the furnace and the packing layer at the upper side of the combustion chamber. The packing layer 7 is formed with bulky carbon-base combustible material and also, the inner part of the packing layer is kept to the high temp. and reduction condition in the packing layer by the combustion control of the burner 8 in the combustion chamber 7 to execute the reduction melting treatment of the treating objective material.

摘要： PROBLEM TO BE SOLVED: To execute the supplying of reducing gas and the heating of a material to be heated with the same heat source in a treating furnace by arranging an independent combustion chamber in each bunker below a conveyor in a heating zone, holding the temp. in the combustion chamber to the high temp., preventing the flowing of unburning component into a furnace and uniformizing the reducing gas in the combustion chamber. SOLUTION: The material to be heated is passed through a preheating zone, heating zone and cooling zone in the furnace 1 with the conveyor 2. Plural burners 3 are fitted to the furnace wall below the conveyor 2 in the heating zone and a box-state combustion chamber 5 composed of refractory in each burner 3 and having gas exhaust hole 4 at here and there. The burner 3 is burnt in low air ratio and generated reducing gas is injected in the furnace 1 from the gas exhaust hole 4. The combustion reaction is limited in the narrow combustion chamber 5 and the refractory around the flame is redheated and thereby, the fuel in the combustion chamber 5 is decomposed into H2 , CO2 and little quantities of C02 , H2 , O and O2 so that methane gas, etc., is not developed in the furnace 1.
