Abstract
The utility model relates to a non-easily deformed forging heating furnace door, and belongs to the technical field of forging heating furnace equipment. The furnace door deformation can be reduced, the service life of the furnace door and a furnace mouth guard plate is prolonged and the energy consumption is reduced. The technical scheme is as follows: the non-easily deformed forging heating furnace door consists of three parts, i.e., a furnace door frame, a furnace door liner assembly and a furnace door guard plate, wherein the furnace door liner assembly is fixedly arranged in a rectangular shell assembled and welded by steel plates through a refractory fiber, and a furnace liner consists of a refractory fiber module and a fiber spreading carpet; a heat-resistant anchor is fixedly arranged on the steel plate, and the furnace door liner assembly is connected with the furnace door frame through bolts; and a first gap is arranged between the furnace door liner assembly and the furnace door frame. The effect of heat irradiation is fully taken into consideration for the whole furnace door from the choice of materials to the structural forms, and a reasonable expansion space is reserved between the various structures, so that the deformation of the furnace door caused by radiation baking of high-temperature furnace gas on the furnace door is reduced and the like. After the non-easily deformed forging heating furnace door is applied, the service life of the furnace door and the furnace mouth guard plate is prolonged, the energy consumption is reduced, and the uniformity of furnace temperature is improved.
Description
Technical field
The utility model relates to a kind of fire door of forge furnace, belongs to the forge furnace equipment technical field.
Background technology
Forge furnace is a very important equipment on the hot-working production line, and fire door need bear high temperature and operation is frequent.Forge Heating furnace door commonly used now is made up of door lining, steel structure frame, fire door shield three parts.The fire door steel construction adopts heavy anti-deformation steel construction, is welded by carbon steel, and the steel construction outer shroud is installed segmented heat resisting cast steel backplate, and door lining adopts and contains chromium or contain zirconium alumina silicate fibre module.
In actual production, find, the fire door ubiquity problem on deformation of using at present, and use distortion more of a specified duration serious more, and cause to run and burn with anger, increase energy consumption, scaling loss fire door and fire door backplate need scheduled overhaul or replacing, and influence is produced, and lowers efficiency.
The reason that produces this situation is that the heating-furnace bore temperature remains on 1200-1300 ℃ for a long time, and door opened frequent.When door opened, only radiation temperature is just up to 800 ℃, and fire door bottom heating temperature is higher; Though the heat resisting steel backplate has been installed around the steel structure frame, steel structure frame receives the hyperthermia radiation baking must thermal expansion, causes malformation impaired; Influence the fire door sealing, occur running the problem of burning with anger, cause stokehold column, fire door backplate scaling loss; Increase energy consumption, reduce the service life of fire door and body of heater, affects safety production.
The utility model content
The utility model technical problem to be solved provides a kind ofly can reduce fire door distortion that high-temperature furnace gas causes the radiant baking of fire door, improve fire door and the service life of fire door backplate, the on-deformable Forge Heating furnace door that cuts down the consumption of energy.
The technical scheme that solves the problems of the technologies described above is:
A kind of on-deformable Forge Heating furnace door, it is made up of furnace door frame, fire door lining assembly, fire door shield three parts, and furnace door frame is welded into frame structure by shaped steel, steel plate; Its improvements are; Fire door lining assembly is fixed in by refractory fibre in the rectangle shell of steel plate assembly welding, and furnace lining is made up of refractory fibre module and fiber tiling blanket, uses heat-resisting anchoring piece to be fixed on the steel plate; Fire door lining assembly adopts bolt to be connected with furnace door frame, between fire door lining assembly and the furnace door frame first gap is arranged.
Above-mentioned on-deformable Forge Heating furnace door, said fire door shield is bolted to around the furnace door frame with heat-resisting, and second gap is arranged between fire door shield and the furnace door frame.
Above-mentioned on-deformable Forge Heating furnace door has a plurality of dilatation joints on the said furnace door frame, dilatation joint is positioned at the top edge of furnace door frame, is uniformly distributed with along the periphery of furnace door frame.
The usefulness of the utility model is:
The utility model with fire door serve as a contrast assembly, fire door shield changes bolt into the connected mode of furnace door frame and is connected; And between fire door lining assembly, fire door shield and furnace door frame, keep certain clearance; Reduced fire door lining assembly to the conduction of furnace door frame heat; The gap air receives the certain convection current of thermosetting simultaneously, and furnace door frame and door shell body are played certain cooling effect;
2. whole fire door has all taken into full account thermal-radiating influence from the material chosen to version, leave rational expansion space between each structure, has reduced fire door distortion that high-temperature furnace gas causes the radiant baking of fire door etc.;
3. cut down the consumption of energy the service life of improving fire door and fire door backplate greatly after using, and improves temperature uniformity.
