Abstract
The utility model provides a heating furnace door sealing device. Heat insulation cotton is both arranged on the inner wall of a furnace body and the inner wall of the furnace door, two sides of the furnace door both exceed the inner sides of two sides of the furnace door, the heat insulation cotton on the inner side of the furnace body extends out of the end of the furnace body, and the heat insulation cotton on the inner side of the furnace door extends out of the periphery of the furnace door. When the furnace door is closed, the furnace door is tightly attached to the end of the furnace body. The heat insulation cotton has elasticity to be tightly pressed between the furnace door and the furnace body. The heating furnace door sealing device has the advantages that the heat insulation cotton is arranged to extend out of the furnace door and the furnace body, and the furnace door and the furnace body are tightly pressed, so that extending heat insulation cotton can partially and effectively prevent heat from flowing out from gaps of the furnace door and the furnace body.
Description
Technical field
The utility model relates to the corollary equipment of mechanical processing industry, specifically, is the sealing device of Compaction of Heating Furnace Door.
Background technology
For the workpiece after forging and the welding processing, carry out stress relief annealing and process, then carry out machining, the quality of heat treatment of workpieces plays the important effect of closing that causes to the serviceability of machining accuracy and workpiece.
Heating furnace is the equipment that steel ingot is heat-treated, and wherein the sealing of heating furnace is played crucial effect to heating quality.
The utility model content
Heating quality in order to ensure heating furnace is high, the good sealing effect of fire door, the utility model has been developed the sealing device of Compaction of Heating Furnace Door, inboard wall of furnace body and fire door inwall are equipped with heat insulation foam, the both sides of described fire door all exceed the inboard of both sides body of heater, the heat insulation foam of described furnace body inside extends the body of heater end, the heat insulation foam of described fire door inboard extend fire door around.
Fire door is closed, is close to the end of body of heater, and heat insulation foam has elasticity, is pressed between described fire door and body of heater.
The beneficial effects of the utility model are: fire door and body of heater are extended in the heat insulation foam setting, and tightly compacted by fire door and body of heater, extended heat insulation foam part has effectively intercepted the drawback that heat flows out from the slit of fire door and body of heater.
Description of drawings
Fig. 1 is structure chart of the present utility model.
The specific embodiment
As shown in Figure 1, the sealing device of Compaction of Heating Furnace Door of the present utility model, body of heater 1 inwall and fire door 2 inwalls are equipped with heat insulation foam 3, the both sides of described fire door 2 all exceed the inboard of both sides body of heater 1, the heat insulation foam 3 of described body of heater 1 inboard extends body of heater 1 end, the heat insulation foam 3 of described fire door 2 inboards extend fire door 2 around.
Fire door 2 closures are close to the end of body of heater 1, and heat insulation foam 3 has elasticity, are pressed between described fire door 2 and body of heater 1.
The utility model extends fire door 2 and body of heater 1 periphery by heat insulation foam 3 is arranged, and effectively raises the sealing effect of heat insulation.
