Description
Technical field
The present invention relates to a kind of belt steel surface coolant emulsion liquid blowing remover.
Background technology
Rolling mill production line band steel needs spray emulsion to implement cooling to it in the operation of rolling, the current subject matter faced can not effectively purge totally for rolling rear plate face emulsion, piebald is formed after drying, emulsion piebald cannot wash in degreasing section, bring to steel strip surface quality and the operation of rolling and have a strong impact on, be mainly manifested in following three aspects:
1, belt steel surface is caused to occur Emulsion spot surface quality defects such as " rusting ".In the bell-type annealing stage, Emulsion spot is also difficult to be removed, and makes high standard cold-reduced sheet such as Automobile Plate product quality not up to standard, becomes the important hindering factor that puzzlement rolling mill production line improves the quality of products; Especially concerning based on the technique of producing annealed sheet, plate face Emulsion spot defect becomes a large bottleneck of limit product Quality advance.
2, emulsion refluence can cause calibrator to detect fluctuation.The accuracy of detection of rolling mill thickness tester reaches a μm level usually, once have emulsion to flow backward to calibrator surveyed area just can affect the accuracy of detection of thickness and detected value fluctuation in the operation of rolling, thus affect automatic thickness control system control accuracy, cause rolling thickness of strips out to there is error.
3, emulsion refluence can cause the inaccurate measurement of tachymeter.Laser velocimeter utilize laser to be incident upon time difference that steel strip surface reflects back into checkout gear again calculates steel plate speed, its accuracy of detection is directly related with plate surface quality.Flow backward to surveyed area if any emulsion, the testing result of laser velocimeter can be subject to king-sized impact, causes the volume per second control of milling train substantially cannot ensure, easily causes the major accidents such as milling train broken belt, curling round the roll.
Current belt steel surface coolant emulsion liquid blowing remover mainly adopts nozzle winding-up form: on hollow circular-tube, equidistantly install the nozzle that quantity does not wait, on-the-spot source of the gas connects hollow circular-tube, is ejected into belt steel surface through nozzle.Form of nozzle mainly contains the nozzle that domestic duck tongue type nozzle and external import are similar to gondola water faucet type.The blow device of two kinds of forms all can be good at removing nozzle just to the emulsion of belt steel surface, and in the region between two between nozzle because pressure is less, pressure is uneven in the width direction at belt steel surface to cause gas, and part emulsion can not purge totally.When fluctuation appears in on-the-spot bleed pressure, both all can not regulate outlet pressure on blow device, and the nozzle of external import is expensive, easily blocks in use procedure.
Summary of the invention
The object of the invention is for above-mentioned present situation, aim to provide a kind of structure simple, cost of manufacture is low; Result of use is good, the belt steel surface coolant emulsion liquid blowing remover of flexible operation.
The implementation of the object of the invention is, belt steel surface coolant emulsion liquid blowing remover, and the stifle of left plate, right plate, upper cover plate and left and right side, transparent cover form a box-structure; Stay pipe is welded on the left of stifle, and air inlet pipe is welded on the right side of transparent cover, and gas blow pipe is welded between stifle and transparent cover, is positioned at box-structure; Gas blow pipe, air inlet pipe communicate; Stay pipe communicates with gas blow pipe or does not communicate;
Have the groove be connected with adjustment plate outside upper cover plate, cross section is that the adjustment plate one side of square is stuck in the groove of upper cover plate, and one side is bolted on upper cover plate; The inside bending in left plate end, is formed to purge and exports between left plate arc upper surface and adjustment plate arc lower surface;
Gas blow pipe three centre positions, are provided with three rows, the venthole be made up of several elongated hole along its length, and the face without venthole just exports purging.
When the present invention works, air inlet pipe is connected with outside air supply system, and stay pipe can installation shaft bearing be connected with rolling-mill housing with air inlet pipe outer surface.Gas blow pipe is one-level air cavity, and box-structure is secondary air cavity.First the gas entered by air inlet pipe enter one-level air cavity, enters secondary air cavity after mixing in the longitudinal direction by three platoon leader holes of gas blow pipe, then through purging outlet winding-up at belt steel surface, purge clean by emulsion residual for belt steel surface.
The inside and outside formation of gas blow pipe of the present invention two air cavitys, play cushioning effect, are conducive to gas and keep equal force value on strip width direction, make the gas pressure continuous uniform being finally ejected into belt steel surface through purging outlet; The gap purging outlet is adjustable, thus can purge situation and bleed pressure timely adjustment purging outlet pressure according to belt steel surface.
The present invention can be directly welded by the steel plate of respective thickness and seamless steel pipe, and do not need the nozzle of purchasing price costliness, cost of manufacture is low; Structure is simple, easy for installation; Result of use is good, flexible operation.
