The utility model comprises a gas-fired heating furnace with a furnace liner, and an electric heating furnace without a muffle furnace, wherein, a gas pipe and a spraying nozzle are arranged on the lateral surface of the gas-fired heating furnace, a steel band inlet opening is arranged at the front section and is provided with a cold and hot air exchanger to preheat the cold air with the heat brought away from a gas flue, a furnace liner is arranged in the gas-fired heating furnace and is connected with the furnace body without the muffle furnace through a flange, a graphite supporting roller is arranged in the middle, an electric heating fire grate is arranged at the lower part of the furnace body without the muffle furnace, breather holes are arranged at the four corners, an explosion proof window and an explosion rupture disc for preventing hydrogen from exploding are arranged at the top part, and the rear end is communicated with a strong convective cooling air blower. The utility model has the advantages that not only the energy cost is saved, but also the utility model can still perform the hydrogen protection atmosphere and maintain the brightness of the stainless steel unchanged, half of the furnace liner is omitted, namely, Killing two birds with one stone. The utility model is ideal equipment with energy conservation, consumption reduction, and cost conservation.
Description
Technical field
The utility model relates to the manufacturing technology field of metallic substance Equipment for Heating Processing, especially shows the coal electricity dual intensity source Stainless Steel Band bright tempering stove that cold rolled stainless steel band carries out anneal.
Background technology
Stainless Steel Band is in constantly cold rolling process, and changing into of its interior molecules structural arrangement makes Stainless Steel Band become more and more harder, therefore just need carry out one time temper behind one cold rolling process of every process.Be used for carrying out this class heat treated all is the electrothermal stove that adds that the muffle furnace of tunnel like promptly is provided with flue in the past; Stainless Steel Band is come in from body of heater one end; through the long flue that is full of the tunnel like of hydrogen is the horse fluorine; Stainless Steel Band is heated annealing in the protection atmosphere of hydrogen; hardness reduces, but the surface still keeps light.Flue in this electric furnace is easy to distortion and scraps because of being heated for a long time.Therefore have the people to invent a kind of bright tempering stove that does not have the horse fluorine, but the power consumption of this stove is bigger, the also corresponding raising of heat treated cost.If change the coal gas heating into, the hydrogen shield atmosphere then is difficult to accomplish.Therefore the transformation to this type of Stainless Steel Band heat treatment furnace is to meet the energy-saving and cost-reducing industry policy of current China.
The utility model content
The purpose of this utility model is: provide a kind of coal electricity dual intensity source Stainless Steel Band bright tempering stove to the cold rolling enterprise of Stainless Steel Band, overcome that the flue of traditional bright tempering stove is yielding to be scrapped and do not have a higher defective of horse fluorine electric furnace energy consumption, provide a kind of ideal equipment for energy-saving and cost-reducing.
The technical scheme of the utility model technical solution problem is: the bright tempering stove is divided into two sections of front and back, and leading portion heats with industrial gas, and the back segment electrically heated is to save half flue and a part of electric energy.The utility model is made of industrial gas pipeline, cold and hot wind interchanger, joint flange and cooling system by being made up of with electrical heater two portions of no horse fluorine the gas-fired furnace of flue.Comprise gas inlet pipe and nozzle, gas-fired furnace, no horse fluorine electric furnace, electrically heated fire grate and joint flange, smoke exhaust pipe, induced draft fan, strong convection cooling blower, cooling water jecket, waste discharge pore, connection terminal and smoke exhaust pipe.Described gas-fired furnace side is provided with gas pipe and nozzle, the inlet end of gas pipe is connected with industrial gas generating furnace, the body of heater front end of gas-fired furnace is the steel band import, and be provided with cold and hot wind interchanger, in establish sinuous coil, its effect is the heat of taking away from smoke exhaust pipe to be heated freezing air carry out UTILIZATION OF VESIDUAL HEAT IN, and the flue gas after the gas-fired is discharged from smoke exhaust pipe.Be provided with flue in gas-fired furnace, the flange outer with the body of heater of the no horse fluorine electrical heater of the other end is connected, and the centre is provided with a graphite rod, the carrying roller when moving as steel band.Described no horse fluorine electrical heater is the rectangular parallelepiped body of heater that relies on the wall sealing, and the bottom is provided with row's nichrome wire heating fire grate, and outer wall is provided with the connection terminal that connects electricity, and eight angles are provided with 8 waste discharge pores on every side; The body of heater top is provided with explosion proof window and the rupture disk that reduces hydrogen accidental explosion power, and the body of heater rear end is connected with flange with the cooling system that is provided with cooling water jecket and strong convection cooling blower.
Benefit of the present utility model is: the leading portion of whole bright heat treatment stove is made the energy with coal; therefore save energy cost not only; and adopt the electrical heater of no horse fluorine in the second half section; still can carry out the hydrogen shield atmosphere and keep stainless light constant; but save the flue of half; be to kill two birds with one stone, so this is a kind of ideal equipment of saving energy and reduce the cost, saving the thermal treatment cost.
Description of drawings
Fig. 1 is a synoptic diagram of the present utility model;
Each title and mark among the figure: 1. smoke exhaust pipe, 2. induced draft fan, 3. gas-fired furnace, 4. plumbago support roller, 5. do not have horse fluorine electric furnace, 6. explosion proof window and rupture disk, 7. electrically heated fire grate, 8. strong convection cooling blower, 9. cooling water jecket, 10. flange, 11. waste discharge pores, 12. connection terminals, 13. gas inlet pipes and nozzle, 14. air intake ducts, 15. steel band imports, 16. cool-heat-exchangers, an outlet of 17. steel bands.
Embodiment
As shown in Figure 1, coal electricity dual intensity source Stainless Steel Band bright tempering stove is by being made up of with electric furnace two portions of no horse fluorine the gas-fired furnace of flue; Comprise gas inlet pipe and nozzle 13, gas-fired furnace 3, no horse fluorine electric furnace 5, electrically heated fire grate 7 and joint flange 10.The import 15 that the Stainless Steel Band that comes out from cold-rolling mill enters gas-fired furnace, the warm air preheating through heat exchanger 16 earlier enters gas-fired furnace 3, is further heated by coal gas, enters no horse fluorine electric furnace 5 heating through joint flange 10 and plumbago support roller 4 then.In electrically heated no horse fluorine electric furnace 5, feed hydrogen and make Stainless Steel Band be subjected to the not oxidized still maintenance of protection of atmosphere of hydrogen bright, but its hardness reduces greatly.Stainless Steel Band comes out from no horse fluorine electric furnace 5, is subjected to the brushing of freezing air of strong convection cooling blower 8 and surface temperature reduces fast, comes out from the exit at last and is rolled into coil of strip, and whole heat treatment process is promptly accused and finished.The effect of explosion proof window and rupture disk 6 is just in case hydrogen contacts with oxygen and blasts, and shockwave at first breaks through the rupture disk of explosion proof window, therefore can reduce the destructive force that explosion hazard causes.
