Fast cold-zone.The workpiece obtained after completing due to punch process, its surface attachment has punching oil, needs
Under hot conditions, punching oil is vapored away by (360 °～460 °), and is discharged by consequent oil smoke
Outside the stove of oil-removing area, this process completes in oil-removing area；Workpiece after oil removing advances to annealed zone,
Full in the stove of annealed zone have carbon monoxide to protect reducing gas, and annealed zone is at 680 °～850 ° bars of furnace temperature
Carbonization treatment and the reduction reaction of workpiece is carried out under part.
In detail, a plurality of rotation and parallel carrying roller, three material advanced it are provided with in the furnace box of oil-removing area
Frame occupies oil-removing area furnace box, and multilayer workpiece is then positioned in each material frame, and furnace box top, oil-removing area is offered
Installing hole is installed for centrifugal blower, and draught fan impeller is positioned at oil-removing area furnace box, arranges near centrifugal blower
There is the smoke exhaust pipe stretched in the furnace box of oil-removing area, owing to furnace box inner air flowing in oil-removing area has deficient unimpeded,
And expect that frame is to march in the furnace box of oil-removing area at ambient temperature, material frame also will contain while entering
The air of moisture content is brought in the furnace box of oil-removing area, and the punching oil of surface of the work attachment simultaneously contains moisture content, this
The moisture that a little moisture content are formed in hot environment concentrates in material frame, it is difficult to drain into oil-removing area through smoke exhaust pipe
Outside furnace box, therefore it is easily caused workpiece and rubescent, phenomenon of getting rusty occurs.
[summary of the invention]
The present invention is directed to above-mentioned the deficiencies in the prior art and provide a kind of continuous annealing to turn blue continuous tunnel furnace oil removing
The special wind-guiding drying device in district, can make the moisture in material frame no longer by oil-removing area stove by this device
Hot-air parcel in case, the workpiece being continuously traveling moisture before the furnace box of removal oil-removing area is filled in time
Divide and be dried, thus avoid workpiece and rubescent, phenomenon of getting rusty occurs.
For solving above-mentioned technical problem, the present invention provides following technical scheme:
Continuous annealing is turned blue the special wind-guiding drying device of continuous tunnel furnace oil-removing area, and this device is installed on oil removing
Furnace box position, district, implements for its moisture of the workpiece in this furnace box is dried the most in time, including band
The vertical centrifugal blower fan of fan shroud, draught fan impeller is positioned at fan shroud, welds in the bottom of described fan shroud
Being connected to flow distribution plate, flow distribution plate bottom surface is welded with collection wind box, and flow distribution plate offers centre bore and radially
Be arranged in multiple diffluence pass of this centre bore periphery at equal intervals, blast pipe stretch into collection wind box in and with shunting
Plate centre bore welding, symmetrically arranged discharge pipe be welded in collection wind box both sides and the most all with this collection wind box phase
Logical.
As supplementing further and perfect technique scheme, present invention additionally comprises following additional
Technical characteristic:
Its mouth of pipe of above-mentioned discharge pipe is arranged down.
Above-mentioned diffluence pass is fan-shaped mouth.
Compared with prior art, the invention have the advantages that and beneficial effect:
After using technique scheme, the moisture in material frame can be made no longer by the heat in the furnace box of oil-removing area
Air wraps up, and furnace air Quick uniform flows, homogeneous temperature, the continuous row of multilayer workpiece in material frame
Enter and moisture is able to the most fully be dried before removal oil-removing area furnace box, it is to avoid be positioned in oil-removing area
Workpiece is rubescent because of moisture for workpiece, get rusty, thus reduce workpiece because of rubescent, get rusty produced one-tenth
Product scrappage, and create advantage for subsequent anneal, process of turning blue, decrease workpiece because of rubescent,
Get rusty and the annealed zone stage additionally take carbon monoxide normally set consumption, annealing workpiece iron loss is few,
Significantly improve carbonization treatment effect and quality of turning blue.
