Description
Technical field
The utility model relates to a kind of fine iron powder reduction furnace, especially a kind of ton fine iron powder reduction furnace.
Background technology
Domestic existing fine iron powder reduction furnace is that flue width is 1000mm to the maximum based on 3000 tons, 5000 tons and 7000 tons substantially, day by day increases iron powder throughput requirements at Powder Metallurgy Industry, requires more and more higher today to energy-saving and emission-reduction.Output more greatly, more energy-conservation ton fine iron powder reduction furnace certainly will be following trend.Now for original reduction furnace, ton fine iron powder reduction furnace needs to solve series of problems technically:
1, for the band oven of continuous operation, productivity gain needs widen width of steel band or improve steel band gait of march exactly;
If 2 widen width of steel band, flue need be strengthened simultaneously and consider the bearing capacity of flue;
3, because output increases, original driving reductor efficiency reduces greatly, need improve.
Utility model content
In view of this, it is large that the purpose of this utility model is to provide a kind of annual production, far away higher than 7000 tons of fine iron powder reduction furnaces, and under same output, and a kind of ton fine iron powder reduction furnace that the atmosphere amount of consumption and electricity reduce greatly.
In order to solve the problems of the technologies described above, the technical solution of the utility model is:
A kind of ton fine iron powder reduction furnace, be characterised in that, it is provided with charging horse not along feed hopper successively to discharging opening direction, heating furnace body, slow cooling section, water-cooled section and discharging sealing device, described feed hopper side is provided with a steel strip tension device, described discharging sealing device one end is provided with a drive unit, is connected with steel band between described steel strip tension device and described drive unit; Described drive unit adopts worm and gear helical tooth speed reducer; The side of one end that described water-cooled section is connected with described slow cooling section is provided with protective gas and cracked ammonium entrance, described protective gas and cracked ammonium porch are also provided with control climate screen, the side of the described water-cooled section other end is provided with water source import, and its relative opposite side is provided with cooling water outlet near position, described slow cooling section;

As shown in Fig. 1 ~ Fig. 2, a kind of ton fine iron powder reduction furnace, be characterised in that, it is provided with charging horse not 2 successively along feed hopper 1 to discharging opening direction, heating furnace body 3, slow cooling section 4, water-cooled section 5 and discharging sealing device 6, described feed hopper 1 side is provided with a steel belt tensioning and fills 8 and put, and described discharging sealing device 6 one end is provided with a drive unit 7, is connected with steel band 9 between described steel strip tension device 8 and described drive unit 7; Described drive unit 7 adopts worm and gear helical tooth speed reducer; The side of one end that described water-cooled section 5 is connected with described slow cooling section 4 is provided with protective gas and cracked ammonium entrance 10, described protective gas and cracked ammonium entrance 10 place are also provided with control climate screen 11, the side of described water-cooled section 5 other end is provided with water source import 12, and its relative opposite side is provided with cooling water outlet 13 near position, described slow cooling section 4;
Described width of steel band L
1for 1500mm, described heating furnace body width L
0for 2800mm ~ 3100mm, described heating furnace body inner furnace adopts corrugated flue tube structure.
Preferably, described width of steel band L
1for 1500mm, described heating furnace body width L
0for 3000mm, wherein said heating furnace body length h in addition
3for 20660mm, described slow cooling section h
0length is 3200mm, described water-cooled segment length h
1for 15000mm.
This technical scheme can cause body of heater long in view of improving steel band gait of march, be unfavorable for in-site installation and use, therefore select to widen width of steel band, and adopt corrugated flue tube structure, calculate applicable rising and wall thickness, meet the working strength under high temperature, in conjunction with worm and gear helical tooth speed reducer, meet and drive requirement.
Certainly, be more than representative instance of the present utility model, in addition, the utility model can also have other multiple detailed description of the invention, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the claimed scope of the utility model.
