Technical field
The utility model belongs to steel band de-scaling production field, and relating in particular to a kind of steel band mechanical removal of oxygen layer is the production equipment of squama.
Background technology
Domestic traditional descaling process generally adopts sulfuric acid, hydrochloric acid, hydrofluoric acid as medium; And spent acid and toxic emission meeting serious environment pollution; Methods such as the electrolysis de-scaling of existing research, laser de-scaling, grinding de-scaling, but in the big production of band steel, still adopt to combine the method for pickling to come de-scaling; Pickling line is to utilize the preliminary treatment of electrolysis as acid-washing stainless steel, to reduce the consumption of nitric acid, hydrofluoric acid.The existing processing method of utilizing electrolysis to replace pickling fully is 200510050164.6 " stainless steel strip and wire rod method for electrochemically removing scale " like application number, earlier with stainless steel material uncoiling and transmission; Again stainless steel material is placed on electrolysis in the de-scaling electrolysis unit.But scale removal effect is undesirable, and device security is poor, and the steel loss is big.
The utility model content
The purpose of the utility model be for addressing the above problem a kind of environmental protection is provided, the steel loss is few, process safety is high, the production equipment of steel scale removal effect steel band mechanical descaling preferably.
The above-mentioned technical purpose of the utility model is achieved through following technical scheme:
A kind of production equipment of steel band mechanical descaling, it comprises the roll nobbling that is used for broken steel strip surface firecoat that sets gradually, is used to brush the band brush device of steel band upper surface break flour and is used to remove the residual firecoat that adheres to of steel strip surface and wash away the sand blasting unit of steel band.
As preferably, said roll nobbling comprises a plurality of row's rollers.
As preferably, said a plurality of row's rollers are arranged on the both sides of steel band alternately.
As preferably, the roller of said row's roller is provided with tooth.
As preferably, the roller of said row's roller is a steel rider.
Steel band is successively through staggered up and down row's roller, 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.Tooth on the roller has strengthened steel band and has contacted the pressure when stressed with roller, and it is broken that oxide layer more is prone to.
As preferably, said band brush device comprise touch roll near the steel band setting, away from the live-roller of steel band and be installed in touch roll and live-roller on the brush band; The adjustable positions of said touch roll and live-roller.
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.
As preferably, the counter-rotation that said brush band transmits along steel band through said live-roller.
As preferably, said sand blasting unit through said nozzle to steel band grit blasting successively, 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.
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.
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 the residual firecoat that adheres to, and guaranteed the effect of washing away again.Make the steel band de-scaling thoroughly clean steel band simultaneously.
Steel band behind roll nobbling, the most of firecoat in top layer is broken and comes off, and removes the residual firecoat break flour of table on the steel band through the band brush device again, sends into the sand blasting unit removing more on a small quantity attached to the firecoat of steel strip surface, simultaneously steel band is washed.
In sum, the utlity model has following beneficial effect:
1, this equipment is adopted completely without sour de-scaling, and pollution-free, technology is simple, and production environment is safer;
2, clean through carrying out steel sand, water under high pressure and high pressure gas de-scaling behind the scale breading again, scale removal effect is good, and steel product quality is good;
3, de-scaling efficient is high, has accelerated the band manufacturing schedule;
4, maintenance of equipment rate is low, and loss is little, has reduced production cost.
