Abstract
The utility model belongs to the field of metal smelting production equipment and particularly relates to mechanical descaling equipment for removing an oxide layer, i.e. scales, on the surface of a steel strip. The mechanical descaling equipment comprises brush roll devices for throwing and brushing the scales on the surface of the steel strip and a sand blasting apparatus for completely removing the scales on the surface of the steel strip. The brush roll devices are row rolls which are symmetrically arranged at both sides of the steel strip. The distance between upper and lower rollers of each row roll is adjustable. The sand blasting apparatus comprises a sand blasting box. A plurality of spray nozzles are arranged in the sand blasting box. The spray nozzles are uniformly distributed at both upper and lower sides of the steel strip. The sand blasting apparatus is used for spraying steel sand, high pressure water and high pressure gas to the steel strip by the spray nozzles. When the steel strip is thrown and brushed by the brush roll devices, most of scales on the surface layer of the steel strip are removed and the steel strip is also leveled to ensure that the subsequent sand blasting apparatus is uniform to descale for the steel strip and the produced steel strip is flat; and the equipment is simple, is high in safety and is more environment-friendly.
Description
Technical field
The utility model belongs to metal smelt production equipment field, relates in particular to a kind of mechanical descaling equipment that the steel strip surface oxide layer is a firecoat that is used to remove.
Background technology
Before cold-rolled strip got into cold rolling program, needing the iron scale of removing steel strip surface was firecoat.The whether clean quality that directly has influence on product of de-scaling, the efficient of production and the problems such as life-span of equipment, more existing machinery and pickling de-scaling way of combining; Use abrasive material that steel surface is carried out ball blast polishing de-scaling, send into acid cleaning process again and carry out pickling, scale removal effect is undesirable; Steel are big in the acid cleaning process loss, and acid mist is very big to human harm, seriously polluted in the production process simultaneously; The spent acid difficult treatment, cost is high, and acid solution corrodes serious to equipment.Like application number is 200610012952.0 the method for iron scale from surface of stainless steel " remove ", be some shot-blasting machines successively continuous operation remove continuously, send into the pickling of pickling section again.
The utility model content
The purpose of the utility model is for addressing the above problem a kind of full machinery, efficient, environmental protection, the integrated mechanical descaling equipment of providing.
The above-mentioned technical purpose of the utility model is achieved through following technical scheme:
A kind of equipment that is used for steel band mechanical descaling is characterized in that: it comprises the brush roll arrangement and the sand blasting unit that is used for thoroughly removing the steel strip surface firecoat that is used to throw brush steel band removal steel band top layer firecoat.
As preferably, said brush roll arrangement is the row's roller that is symmetricly set in said steel band both sides.
As preferably, the distance between said row's roller down roller is adjustable.
As preferably, said sand blasting unit comprises blasting cabinet, is provided with a plurality of nozzles in the said blasting cabinet.
As preferably, said nozzle is distributed in the both sides up and down of said steel band.
As preferably, said sand blasting unit through said nozzle to steel band grit blasting, water under high pressure and high pressure gas.
As preferably, the pressure of supply water of said water under high pressure is 6-10Mpa; The supply gas pressure of said high pressure gas is 0.7Mpa.
Respectively be provided with three row's nozzles in the blasting cabinet up and down, three row's nozzles connect steel sand feed bin, water under high pressure feed bin, high pressure gas feed bin successively, after steel band is sent into blasting cabinet, successively to steel band upper and lower surfaces grit blasting, water under high pressure, high pressure gas.Smash and wash away firecoat.Nozzle respectively is set up and down, and the steel band that need not to overturn carries out the reverse side de-scaling, has reduced operation and equipment.
As preferably, said nozzle axial direction and steel band are the angle of 40-50 degree.
The angle that is provided with had not only guaranteed that steel sand, water under high pressure and high pressure gas were sprayed onto steel strip surface and produce enough pressure breakings and dash and remove firecoat but also guarantee to wash away clean effect.The obstruction that falling possibly cause with sand of also anti-sealing guarantees that two-sided de-scaling carries out simultaneously.
Brush away except that the most of firecoat in steel band top layer through the brush roll arrangement throwing, send into sand blasting unit again and wash away clean steel band simultaneously through the residual firecoat of the thorough removing of steel sand, water under high pressure and high pressure gas.
In sum, the utlity model has following beneficial effect:
1, sand blasting unit is interior will overlap the de-scaling mode more and combine to steel strip surface grit blasting, water under high pressure and high pressure gas, improve the effect of de-scaling greatly;
2, throw the brush steel band through brush roll arrangement, the most of firecoat in steel band top layer is removed, and flattens steel band simultaneously to guarantee the postorder sand blasting unit, and the steel band de-scaling is even, and the steel band of production is smooth;
3, equipment is simple, and security is good, more environmental protection;
4, de-scaling efficient is high, quality of finished product good.
