According to the descaling device provided by the utility model, a plurality of mechanical descaling working procedures are combined, so that the steel strip surface scales are thoroughly cleaned in a non-pickling condition, therefore the descaled steel strips have the characteristics of low roughness and good quality; and the production environment is safer.
Description
Technical field
The utility model belongs to the steel band production field, relates in particular to a kind of de-scaling equipment that steel strip surface oxide skin is firecoat of removing.
Background technology
The steel band cold rolling feeds can produce fine and close iron scale attached to steel strip surface in course of hot rolling, have a strong impact on the article phase of steel band, and the big frictional force that the simultaneous oxidation iron sheet produces shortens the roll life cycle of cold rolling usefulness of later stage, has improved production cost.Traditional descaling method is steel to be immersed in carry out the pickling de-scaling in the multiple acid solution; Also have burrock is set in descaling bath; Spout nozzles is set in burrock; Acid jetted to steel, carry out the pickling de-scaling, above acid washing method all is difficult to meet the requirements of the fineness of cleaning effect and steel surface.In acid cleaning process, also inevitably produce overpickling (i.e. the reaction of acid and steel itself generation) and steel hydrogen embrittlement, the steel loss is big.The acid mist that pickling produces causes very big injury to human body, and it is big that the spent acid after the pickling is handled investment, and occupation of land is many, contaminated environment, and acid solution is had relatively high expectations to production equipment simultaneously, and loss is bigger.For reducing the use of acid solution; The method of more existing mechanical descalings uses abrasive material that steel surface is carried out ball blast polishing de-scaling before pickling, sends into acid cleaning process again and carries out pickling; It like application number a kind of method of removing iron scale from surface of stainless steel of 200610012952.0; Some shot-blasting machines continuous operation are successively removed continuously, the steel sand of SM150 model is added to the feed bin of shot-blasting machine, remove the iron scale of stainless steel hot-rolling surface of steel plate with steel sand.The de-scaling of ball blast process is not thorough, and the steel article after the pickling differ, and can not avoid pickling to bring, and steel, equipment loss are big, problems such as environmental pollution.
The utility model content
The purpose of the utility model be provide for addressing the above problem that a kind of environmental protection, steel loss are few, de-scaling thoroughly, steel article phase steel band de-scaling preferably equipment.
The above-mentioned technical purpose of the utility model is achieved through following technical scheme:
Steel band de-scaling equipment comprises roll nobbling, the sand blasting unit that is used to wash away removal steel strip surface firecoat that is used for broken steel strip surface firecoat, the cleaning device that is used to throw the brush roll arrangement of brush steel band and is used to clean steel band.
As preferably, said roll nobbling comprises a plurality of row's rollers one, and said a plurality of row's rollers one are arranged on the both sides of steel band alternately.
Steel band is successively through staggered up and down row's roller one, and through repeatedly turning to bending, the pressure that tension force that the bending process produces and roller are applied on the steel band comes off the oxide layer fragmentation attached to steel strip surface.
As preferably, the roller of said row's roller one is a steel rider.
Row's roller one roller is provided with tooth.Tooth on the roller has strengthened steel band and has contacted the pressure when stressed with roller, and it is broken that firecoat more is prone to.
As preferably, said sand blasting unit comprises blasting cabinet, is provided with a plurality of nozzles in the said blasting cabinet; Said nozzle is distributed in the both sides of steel band.
Nozzle respectively is set up and down in the blasting cabinet, and the steel band that need not to overturn carries out the reverse side de-scaling, has reduced operation and equipment.
As preferably, said brush roll arrangement is the row's roller two that is arranged at said steel band both sides.
As preferably, said cleaning device comprises a casing, is positioned at steel band in the said casing and is evenly equipped with out sprinkler head in both sides up and down; Said water outlet shower nozzle axial direction and steel strip surface are the angle of 30-45 degree.
Shower nozzle is set and steel strip surface is angled, the firecoat break flour is rinsed out towards a direction with current, flushing surface is bigger, and the flushing scale removal effect is better.The shower nozzle that the certain angle current are difficult for falling back to the steel band bottom is set, causes obstruction, guarantee that upper and lower surfaces washes simultaneously, reduced equipment and operation.
As preferably, said sand blasting unit through said nozzle to steel band grit blasting, water under high pressure and high pressure gas; 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.
As preferably, said nozzle axial direction and steel strip surface are the angle of 40-50 degree.
Certain angle washes away the firecoat that comes off in the same direction, and the angle of setting had both guaranteed that steel sand, water under high pressure and high pressure gas were sprayed onto steel strip surface and produce enough pressure breakings towards removing firecoat, guaranteed the effect of washing away again.Make the steel band de-scaling thoroughly also reduce the break flour that adheres to.
Steel band behind roll nobbling, the most of firecoat in top layer is broken and comes off, and removes the residual firecoat of firm attachment in steel strip surface through sand blasting unit again; Relatively cleaner through the steel band top layer after the sand blasting unit de-scaling; But have certain roughness, and some steel sands of residual embedding, the brush steel strip surface thrown through brush roll arrangement again; Make steel strip surface smooth, simultaneously further de-scaling is also removed the minute quantity steel sand that possibly embed.Clean rolling through cleaning device again.Through the cooperation of above multiple working procedure, the steel band oxide layer after the processing is removed thoroughly, surface-brightening.
In sum, the present invention has following beneficial effect:
1, this equipment adopts the mode of full mechanical descaling, the environmental pollution of having avoided pickling to cause, Environmental Safety more;
2, the combination of multiple tracks mechanical descaling operation makes steel band under no pickling situation, thoroughly remove the firecoat of steel strip surface, and the steel band roughness is low, and quality is good;
3, technology is simple, and production efficiency is high, has increased product profit;
4, the recyclable utilization of oxide skin.
