Description
Technical field
The utility model relates to a kind of heating mantles of recrystallize bright annealing equipment, specifically, is the heating mantles in a kind of cold rolled strip coil annealing equipment.
Background technology
Metallic material product can carry out anneal mostly before making finished product, its main purpose is: eliminate the sclerosis and the unrelieved stress that produce in the course of processing, improve material plasticity and processing characteristics; Change the weave construction of material, obtain needed grain fineness number and grain orientation.The equipment that is used for cold rolled strip coil of strip recrystallize clean annealing on producing at present generally is made up of table, outer heating mantles, interior material cover, convection current plate, energy medium pipeline etc.The middle and lower part of heating mantles cover wall is provided with at least one row's heating unit (as burner) outside.After annealing cold rolled strip coil of strip is placed on the table support; cover coil of strip and table with interior material cover; and by hydraulic gear with the sealing of interior material cover and table, for preventing coil of strip surface oxidation in annealing process, material cover holds a kind of by blower fan forced convection round-robin shielding gas in this.Recirculation blower is arranged on the table below, the shielding gas convection circulation in making in the material cover.When cycle of annealing starts; expect internally that by the heating unit that is arranged on the outer heating mantles cover carries out heat supply; and coil of strip is conducted heat by the thermal radiation of interior material cover; shielding gas forced convection circulation in recirculation blower then drives in the material cover; heat is just strengthened the convection current conduction through the slit between coil of strip and the convection current plate like this, improves the rate of heating and the even purpose of the peripheral critical temperature of coil of strip thereby reach.
In the heat treatment process of coil of strip in annealing device, the easy degree of the size of the homogeneity of being heated, the speed of rate of heating, thermosteresis, the height of thermo-efficiency and loading and unloading all is key factors of restriction coil annealing quality and output.Existing outer heating mantles, owing to adopt the mode of fixing heating, coil of strip is heated and is inhomogeneous in annealing process, and rate of heating is slow, thermosteresis is big, thermo-efficiency is low, annealing quality and output all are difficult to be guaranteed.
Summary of the invention
The purpose of this utility model is exactly to solve the deficiency that the above-mentioned background technology exists, and proposes a kind of simple in structure, annealing quality and output height, the heating mantles in the time of making annealing in the uniform cold rolled strip coil annealing of the thermal radiation equipment.
At above-mentioned purpose, heating mantles in the designed cold rolled strip coil annealing equipment of the utility model, the outer heating mantles that comprises the table body, is used to seal the interior material cover that covers the table body and is used to cover interior material cover, the top of described outer heating mantles offers pilot hole, being provided with in the described pilot hole can be along the flexible portable heating arrangements of y direction, and described interior material cover is provided with from the top and extends the cavity that is used to hold portable heating arrangements downwards.
Further, described portable heating arrangements is the water-cooled gas gun.
Advantage of the present utility model is: owing to be provided with the portable heating arrangements that stretches into outer heating mantles inside on the heating mantles outside, the thermal radiation that the material cover transmitted in coil of strip can be accepted on the one hand from outside to inside in annealing process, coil of strip can be accepted the thermal radiation from the inside to the outside that described portable heating arrangements provides on the other hand, coil of strip can fully absorb heat, and can guarantee that the radiation of coil of strip internal and external temperature is even, improved thermo-efficiency, reduce when knowing clearly the lehr attendant, improved the production capacity of annealing device and the quality of annealing product; And the utility model is simple in structure, can directly be formed by existing annealing device transformation, and manufacturing cost is very cheap.
Description of drawings
Fig. 1 is the structural representation of the heating mantles in the cold rolled strip coil annealing equipment.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Heating mantles in the cold rolled strip coil annealing equipment shown in the figure, the outer heating mantles 1 that comprises table body 8, is used to seal the interior material cover 2 that covers table body 8 and is used to cover interior material cover 2.Described 1 upper edge inner cover wall Lower Half week of outer heating mantles is evenly disposed two row's burners 6 along dividing; Install on outer heating mantles 1 outer wall and be provided with burner blower 4 and interchanger 5.The fuel gas buring that described burner blower 4 and interchanger 5 provide preheated air and burner 6 places to spray for burner 6, thus heat provided for outer heating mantles 1.Described outer heating mantles 1 side arrangement has a guidepost 9, and described guidepost 9 is a vertical stock, and its effect is when the outer heating mantles 1 of lifting, provides reference for guaranteeing vertically to lift.
Outer heating mantles 1 top portion offers pilot hole 10, but is furnished with longitudinal extension in the described pilot hole 10 and stretches into portable heating arrangements 3 in the outer heating mantles 1.Material cover 2 is provided with the cavity 11 that portable heating arrangements 3 is held in along the top downward being used in described.Described portable heating arrangements 3 can provide the internal radiation thermal source for coil of strip when annealing, its work area can be along moving up and down in controlled area charactert along y direction within interior material cover 2.When needing inner the heating, portable heating arrangements 3 stretches into outer heating mantles 1, extends in the cavity 11.The high water-cooled gas gun of described portable heating arrangements 3 preferred thermo-efficiency.
Principle of work of the present utility model is as follows: when annealing coil be positioned be placed on the table body 8 after, with interior material cover 2 cover coil of strip and table body 8 and with 8 sealings of table body, and outer heating cover body 1 on the back cover, and interior material cover 2 in the injection shielding gas.When cycle of annealing starts, at first coil of strip is heated, on the one hand by the thermal radiation of interior material cover 2 coil of strip is heated from outside to inside by outer heating mantles 1; In stretching into, in the cavity 11 of material cover 2, from the inside to the outside coil of strip is heated portable on the other hand heating arrangements 3; Meanwhile, the shielding gas forced convection circulation in table blower fan 7 drives in the material cover, heat is just strengthened the convection current conduction through coil of strip and the slit between the convection current plate like this, thereby reaches the effect that improves rate of heating and the peripheral critical temperature of even coil of strip.After heat-processed is finished, coil of strip is cooled off; this moment, outer heating mantles 1 stopped heat supply; portable heating arrangements 3 is extracted cavity 11 out and is stopped heating; hot protective gas in table blower fan 7 is extracted out in the material cover 2; send into cryogenic gas simultaneously; formation forced convection circulation, coil of strip is finished whole annealing process under the cooling of cryogenic gas.
