In detail, be provided with many in the stove case of oil-removing area to rotate and the carrying roller paralleled, three material frames of advancing occupy oil-removing area stove case, multilayer workpiece is then positioned in each material frame, the installing hole that stove box top, oil-removing area is offered is installed for centrifugal blower, draught fan impeller is positioned at oil-removing area stove case, the smoke exhaust pipe stretched in the stove case of oil-removing area is provided with near centrifugal blower, because stove case inner air flowing in oil-removing area has deficient unimpeded, and expect that frame marches in the stove case of oil-removing area at ambient temperature, also the air containing moisture content is brought in the stove case of oil-removing area while material frame enters, the punching oil of surface of the work attachment simultaneously contains moisture content, the moisture that these moisture content are formed in hot environment concentrates in material frame, be difficult to drain into outside the stove case of oil-removing area through smoke exhaust pipe, therefore workpiece is easily caused to occur rubescent, to get rusty phenomenon.
[summary of the invention]
The present invention is directed to above-mentioned the deficiencies in the prior art and the special wind-guiding drying device turned blue in continuous tunnel furnace oil-removing area in a kind of continuous annealing is provided, can make to expect that the moisture in frame is no longer wrapped up by the hot-air in the stove case of oil-removing area by this device, the workpiece be continuously traveling moisture before shifting out oil-removing area stove case is able to fully dry in time, thus avoids rubescent, the phenomenon of getting rusty of workpiece appearance.
For solving the problems of the technologies described above, the invention provides following technical scheme:
Continuous annealing is turned blue the special wind-guiding drying device of continuous tunnel furnace oil-removing area, this device is installed on Lu Xiang position, oil-removing area, implement for the drying fully in time of its moisture of workpiece in this stove case, comprise the vertical centrifugal blower fan of band fan shroud, draught fan impeller is positioned at fan shroud, flow distribution plate is had at the bottom welding of described fan shroud, flow distribution plate bottom surface is welded with collection wind box, flow distribution plate offers centre bore and is radially arranged in multiple diffluence pass of this centre bore periphery at equal intervals, blast pipe stretches into and collects in wind box and weld with the centre bore of flow distribution plate, symmetrically arranged discharge pipe is welded in collection wind box both sides and all communicates with this collection wind box.
As to technique scheme supplement further and perfect, the present invention also 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, tool of the present invention has the following advantages and beneficial effect:
After adopting technique scheme, can make to expect that the moisture in frame is no longer wrapped up by the hot-air in the stove case of oil-removing area, furnace air Quick uniform flows, homogeneous temperature, multilayer workpiece in material frame is continuously traveling and moisture is able to fully dry in time before shifting out oil-removing area stove case, avoid be arranged in oil-removing area workpiece because of moisture workpiece rubescent, get rusty, thus reduce workpiece because of rubescent, the finished product scrappage getting rusty produced, and be subsequent anneal, process of turning blue creates advantage, decrease workpiece because of rubescent, get rusty and additionally take the normal setting consumption of carbon monoxide in the annealed zone stage, annealing workpiece iron loss is few, significantly improve carbonization treatment effect and quality of turning blue.
