The consistent temperature type annealing furnace comprises a sealing furnace body (1), one end of the furnace body (1) is provided with a furnace door (2), and the inner part of the furnace body (1) is provided with a movable material bracket (3). The consistent temperature type annealing furnace is characterized in that the inner wall of the upper end of the furnace body (1) is connected with more than two heating resistors (4), and a partition plate (5) is arranged between the heating resistors (4) and the material bracket (3).
Description
Technical field
The utility model relates to a kind of annealing furnace, especially relates to a kind of to the isostructural improvement of thermostatic type annealing furnace.
Background technology
The annealing of aluminium alloy comprises pre-annealing, process annealing and final finished annealing.The purpose of pre-annealing and process annealing is to improve tissue and processability, makes product be easy to processing in the course of processing.The purpose of final annealing is for tissue that obtains to require and performance, and supply status, also can eliminate the harm of unrelieved stress simultaneously.In order to make finished product that stable mechanical property be arranged, require the temperature of annealing furnace to want accurately evenly, the temperature difference is less in the stove, the temperature difference should be controlled at ± 10 ℃ in.Chinese patent discloses a kind of continuous annealing furnace furnace binding, and (Granted publication number: CN200971374Y), it is provided with partition wall between two adjacent warm areas, and partition wall is provided with the aluminosilicate fiberboard of steel plate for the surface, and steel plate is 1Cr18Ni9Ti.But this annealing furnace is not to utilize heating resistor that material is heated, and heating unit directly heats material, and the temperature difference is bigger.Chinese patent also discloses a kind of aluminium resistance annealing stove (Granted publication number: CN2144284), it installs one or more blower fan in the center of top that case structure contains the airtight body of heater of thermal insulation layer, by guiding device burner hearth is divided into labor and materials shallow storage space and furnace atmosphere circulation heat exchanger channels, the bayonet type electric heater equidistantly is hung on the passage top, furnace roof is equipped with the furnace pressure stopple coupon, the elevator fire door adopts the sealing of tubulose envelope cutter, by microcomputer and temperature controller control furnace temperature, blower fan is the bidirectional reversible aerofoil fan, and the furnace pressure stopple coupon is for being communicated with the closed conduit of burner hearth and furnace pressure indicating unit; The closed circuit water circulating pipe of the fire door tubulose envelope integrated formula straight cooling type of cutter; The microcomputer temperature control system makes upper computer by microcomputer, and the intelligent digital temperature controller is made the next instrument, constitutes to concentrate-distributing microcomputer temperature control system.But the structure more complicated of this resistance furnace, blower fan need be installed a plurality of, and manufacturing cost is bigger.Comparatively simple in addition annealing furnace also is that heating unit directly heats material as shown in Figure 1, and the temperature difference is bigger.
The utility model content
The utility model technical issues that need to address provide a kind of thermostatic type annealing furnace, it mainly is to solve the existing in prior technology heating unit directly material to be heated, and the temperature difference is bigger, the structure more complicated of resistance furnace, blower fan need be installed a plurality of, the technical problem of the bigger grade of manufacturing cost.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Thermostatic type annealing furnace of the present utility model, the body of heater that comprises sealing, body of heater one end is provided with fire door, and body of heater inside is provided with the material frame, it is characterized in that being connected with on the inwall of described body of heater upper end 2 and, be provided with dividing plate between heating resistor and the material frame with last heating resistor.Can be provided with tightness system between fire door and the body of heater.Can put pending metal wire on the material frame.Dividing plate can be made by the stainless steel plate material, and it has avoided heating resistor directly material to be heated, and causes the big temperature difference.
As preferably, the gap is left at described dividing plate and body of heater two ends, on the body of heater of dividing plate one end recirculation blower is installed.Form convection channel between the inwall at dividing plate and body of heater top, and recirculation blower is installed in the inner of body of heater, it can be extracted into recirculating air in the stove on the convection channel between convection channel dividing plate and the body of heater, and then get back in the body of heater, adopt warm air that material is heated, and adopt temperature controller control heating resistor, can reach the uniform purpose of temperature in the stove like this.By test, the annealing furnace after the improvement is after being heated to specified temperature, and lower variation of tolerance is ± 5 ℃ on the temperature difference in its stove, has reached the annealed standard-required, has stablized the quality of product.
As preferably, described heating resistor is 3～6, and dividing plate is suspended on the inwall of body of heater upper end by fixed link.Every fixed link can be located between two heating resistors.
Therefore, the utlity model has between the heating resistor of annealing furnace and material and add a dividing plate, load onto a recirculation blower at dividing plate one end, make furnace air form convection current, warm air with convection current heats material, make that the temperature of material heating is even, the metal wire stable mechanical performance after the thermal treatment, characteristics such as simple and reasonable.

Accompanying drawing 1 is a kind of structural representation of former annealing furnace;
Accompanying drawing 2 is a kind of structural representations of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the thermostatic type annealing furnace that this is routine, as Fig. 2, for carrying out the horizontal annealing furnace of anneal to metal wire, it comprises the body of heater 1 of sealing, body of heater 1 outer end is connected with fire door 2.The inside of body of heater 1 is provided with the active that can place metal wire material 8 can release material frame 3, be connected with 5 heating resistors 4 on body of heater 1 inwall of material frame 3 tops, and be hung with dividing plate 5 by fixed link 7 on the inwall at body of heater 1 top, dividing plate and body of heater top inner wall form convection channel, and the gap is left at dividing plate and body of heater two ends.One end of dividing plate 5 is that the inner end of body of heater 1 is provided with recirculation blower 6.
During use, heating resistor 4 can heat material 8, recirculation blower 6 is extracted into the hot blast of body of heater 1 heating zone on the convection channel in the inner end of body of heater 1, and then be withdrawn into the heating zone of body of heater 1 again in the outer end of body of heater 1 from convection channel, the recirculating air trend has reached the comparatively uniform purpose of temperature in the stove like this as the direction of arrow among Fig. 2.
