Description
Technical field
The utility model relates to annealing device field, relates in particular to the annealing furnace that aluminium sheet circle is annealed.
Background technology
Annealing is to make through casting, forging rolling, the material of welding or machining or workpiece are softening, improve plasticity and toughness, make chemical composition homogenizing, remove unrelieved stress, or obtain expection physicals, therefore be also a conventional process in the aluminium course of processing, annealing furnace is indispensable processing units in annealing processing, the former use open type of the applicant annealing furnace, heating unit directly hangs on body of wall, in annealing process, by electric-heating-wire-heating, temperature ecto-entad spreads, so just form non-uniform temperature in burner hearth, position temperature near nichrome wire is high, and the temperature of burner hearth middle portion is low, cause the annealing cycle long, energy consumption is large, more than aluminium sheet circle annealing current consumption per ton 500 ~ 550KWH, and annealing hardness differs, quality cannot guarantee, percent defective reaches 30%.
Utility model content
The applicant, for the shortcoming existing in above-mentioned prior art, proposes the closed annealing furnace of a kind of aluminium sheet circle, and it is simple in structure, can produce uniform temperature field, improves annealing efficiency and energy consumption low.
The technical scheme that the utility model adopts is as follows:
The closed annealing furnace of aluminium sheet circle, comprises burner hearth, and described burner hearth is comprised of both sides furnace wall and furnace roof, and the bottom of described burner hearth and inner side-wall be arranged in parallel respectively guide rail and dividing plate, be provided with nichrome wire between two parallel guides and between dividing plate and furnace wall; On guide rail, put material placing casing; Between two dividing plates, by wind scooper, join, between wind scooper and furnace roof, aerofoil fan is installed, on wind scooper, be positioned at aerofoil fan below with through hole; Both sides dividing plate and described burner hearth bottom leave gap; The opening part of described burner hearth is provided with fire door;
Further technical scheme is as follows:
Preferably, steel plate reinforcement is passed through in described burner hearth outside;
Preferably, the lifting mechanism that install with furnace roof edge fire door upper end is connected;
Preferably, fire door is positioned at the groove of furnace wall two side shields;
Preferably, lifting mechanism is connected by steel cable with fire door.
The beneficial effects of the utility model are as follows:
1, two Fans, by the freezing air in burner hearth, sucks air channel, passes through electric-heating-wire-heating, by bottom, flowed in burner hearth, utilize blower fan to carry out forced heated air circulation, form hot-air convection, make interior ground of burner hearth temperature even, the annealing quality of aluminium sheet circle is greatly improved, and yield rate reaches more than 99%;
2, steel plate reinforcement burner hearth makes it firmer, increases the service life;
3, can control according to actual needs the lifting of fire door, laborsaving and efficiency is high;
4, the groove of baffle plate plays guide-localization effect to fire door, is conducive to the sealing of fire door to burner hearth;
5, directly adopt steel cable to connect, simple in structure, cost-saving.
accompanying drawing explanation:
