Description
Technical field
The present invention relates to aluminum processing technology field more particularly to a kind of dead weight locked annealing furnaces.
Background technology
Annealing furnace is the metallurgical and common thermal processing equipment of machinery industry.It is, in general, that annealing treating process is smelting
The last treatment process of gold and engineering goods, its treatment effect will directly affect the quality of product.
There are many type of annealing furnace, have oil burner, gas furnace, electric furnace etc. by fuel point.
1, oil burner：Since the surface quality requirements after being heat-treated to product are higher, heating accuracy is required also very sternly, therefore
The annealing stove of fuel oil is generally used light diesel fuel.This also brings some problems, such as：Light diesel fuel price is more expensive, need to set
Set oil supply system etc..
2, gas furnace：Compared with fuel oil thermal treatment furnace, combustion gas makes annealing treatment stove and is ensureing product quality, improves annealing
Advantage is just had more in terms of the efficiency of furnace.Gas furnace proposes control device and control method very high requirement, therefore, combustion gas annealing
Treatment furnace is in metallurgical and machinery industry using less.
3. electric furnace：Electric furnace is as a kind of effective annealing heating equipment, the simple, temperature control precision with its control
It the features such as height, high heat treatment rear surface quality, is widely used in production.
Aluminium processing industry, the annealing furnace made annealing treatment to aluminium volume mostly use electric furnace.Existing annealing furnace includes furnace body,
Furnace body includes front wall, rear wall, left side wall, back side wall, roof and bottom wall, and burner hearth is equipped in furnace body, and furnace body front wall is equipped with and is used for
The door opening of material is passed in and out, fire door is equipped at door opening.
Annealing furnace is at work, internal to be in the condition of high temperature.If fire door is not closed completely, it can be lost in big calorimetric outward
Amount, causes energy dissipation.It leaks to reduce hot gas, fire door is pressed on stove by existing annealing furnace at work, using cylinder
On body, this aspect increases the complexity of annealing system, increases equipment cost, on the other hand also improves the complexity of operation
Property.

Fire door top, then lifting device transmission shaft needs be arranged very high, could after fire door upwardly opens be still higher than fire door
Top can just play castering action.When promoting fire door in the present invention, a left side for the middle and lower part of fire door is suspended in midair by chain lifting mechanism
Right both sides, therefore i.e. fire door is flush even slightly above transmission shaft after upwardly opening with transmission shaft, can still play effectively
Castering action.
The lower part of dead weight locking inclined plate is connected with stiffener plate, and the other end of stiffener plate is connected to the slot of fire door guide groove
On wall, triangular support structure can be formed between the cell wall, dead weight locking inclined plate and stiffener plate of fire door guide groove, enhanced
Structural strength.
When fire door lifts, transverse slat guide groove plays limit by transverse slat guide plate, upper cross plate and lower cross plate to fire door
Effect makes process that is door opened and closing more stablize.
