Abstract
The utility model provides a pusher-tray type annealing energy-saving furnace which comprises a furnace body formed by a furnace roof and a furnace bottom. Both sides of the furnace body are provided with furnace doors; the interior of the furnace body is provided with an ascending combustion flue and a descending combustion flue which are both internally provided with conveyer belts; and the inner walls of the furnace roof and the furnace bottom and a separation wall between the ascending combustion flue and the descending combustion flue are all provided with temperature controlling components. The pusher-tray type annealing energy-saving furnace has the advantages that the upper side and the lower side of the ascending combustion flue and the descending combustion flue are both provided with the temperature controlling components which can better control the needed furnace temperature, simultaneously the furnace wall is thickened so as to have better thermal insulation effect, thus causing workpieces to better crystallize in the needed temperature range. The workpieces can have higher stability.
Description
Technical field
The utility model relates to a kind of pusher tray annealing energy saving furnace, belongs to thermal treatment process equipment technology field.
Background technology
Usually the anneal of mechanical component adopts spheroidal annealing process, to obtain tiny and uniform nodularization pearlitic structure.Spheroidizing Annealing is a kind of of underannealing, refers to the sheet cementite in the steel Medium pearlite and proeutectoid cementite are converted into the spherical or granular carbide that is uniformly distributed on the ferrite matrix to obtain the heat treating method of globular pearlite.But existing equipment technology makes that the annealing process cycle of product is long, and energy consumption is big, and unstable product quality, and the hardness scattered error is big, energy-saving and cost-reducing, under the requirement of the green industry of development, needs a kind of less energy-consumption, high efficiency pusher tray annealing energy saving furnace.
The utility model content
The purpose of this utility model provides a kind of less energy-consumption, high efficiency pusher tray annealing energy saving furnace, and the purpose of this utility model realizes by following technical scheme is provided:
A kind of pusher tray annealing energy saving furnace, comprise the body of heater of forming by furnace roof and furnace bottom, the both sides of described body of heater are provided with fire door, be provided with up combustion flue, descending combustion flue in the body of heater, be provided with conveying belt in the described up and down combustion flue, described furnace roof and described furnace bottom inwall, and described up combustion flue and descending combustion flue between divider wall in be provided with the temperature control assembly.
Further, described furnace roof furnace wall thickness thickening is to 500 millimeters.
Further, described furnace bottom furnace wall thickness thickening is to 500 millimeters.
Again further, described temperature control assembly is made up of heating unit, thermopair and temperature controller, and described thermopair is arranged on described furnace roof and described furnace bottom inwall, reaches in the divider wall between described up combustion flue and the descending combustion flue.
Further, described heating unit is a resistive band.
The beneficial effects of the utility model are mainly reflected in: the upper and lower sides of up-downgoing combustion flue all is provided with the temperature control assembly, can control required furnace temperature better, better insulation effect is also played in the thickening of furnace wall simultaneously, thereby make workpiece more crystalline in temperature required scope, workpiece can have higher stability.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the synoptic diagram of specific embodiment of the utility model.
Wherein:
1 furnace roof, 2 furnace bottoms
3 fire doors, 4 up combustion flues
5 descending combustion flue 6 conveying belt
7 thermopairs
Embodiment
Following with reference to the description of drawings specific embodiment of the utility model.
With reference to Fig. 1, a kind of pusher tray annealing energy saving furnace of the utility model specific embodiment, comprise the body of heater of forming by furnace roof 1 and furnace bottom 2, the both sides of body of heater are provided with fire door 3, be provided with up combustion flue 4, descending combustion flue 5 in the body of heater, the combustion flue bottom all is provided with conveying belt 6 up and down, and workpiece is transporting motion by the conveying of conveying belt 6 respectively up combustion flue 4, descending combustion flue 5 after fire door 3 enters.
All be provided with the temperature control assembly in the divider wall between furnace roof 1 and furnace bottom 2 inwalls and up combustion flue 4 and the descending combustion flue 5, this temperature control assembly is made up of heating unit, thermopair 7 and temperature controller.Be provided with a design temperature in the described temperature controller.When workpiece transported in stove, the temperature control assembly detected temperature in the stoves by thermopair 7, if do not reach design temperature, then temperature controller can be controlled heating unit and starts and heat; After surpassing design temperature, then temperature controller can be controlled heating unit and stops heating.
In this preferred embodiment, heating unit is a resistive band.The resistive band well heater generally is used for the heating installation of drying tunnel, drying room, baking oven more, can certainly adopt other heating unit.In addition, thermopair is one of industrial the most frequently used detector unit.Its advantage is: 1. measuring accuracy height.Because of thermopair directly contacts with measurand, be not subjected to the influence of intermediate medium.2. useful range is wide.But thermopair commonly used is continuous measurement from-50～+ 1600 ℃ of equal limits, and special thermopair is minimum measures-269 ℃ (as golden iron nickel chromium triangles) for some, reaches as high as+2800 ℃ (as tungsten-rhenium).3. simple structure is easy to use.Thermopair normally is made up of two kinds of different wires, and is not subjected to the restriction of size and beginning, and protective casing is arranged outward, uses very convenient.Therefore, adopt thermopair in this preferred embodiment as temperature element, certainly other temperature element also can, hot resistance or the like for example.
In the utility model, the wall thickness of furnace roof 1 and furnace bottom 2 has all been done thickening setting, all reaches 500 millimeters, makes the interior temperature of stove to be incubated.
What need understand is: above-mentioned explanation is not to be to restriction of the present utility model, and in the utility model design scope, the interpolation of being carried out, conversion, replacement etc. also should belong to protection domain of the present utility model.
