The above-mentioned technical purpose of the utility model is achieved through following technical scheme:
The production equipment of band steel mechanical descaling comprises the sand blasting unit that is used to remove the belt steel surface firecoat that sets gradually, the cleaning device that is used to brush the band brush device of the residual break flour of band steel upper surface and is used for the flushed zone steel.
As preferably, 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 of band steel.
As preferably, said band brush device comprise near the touch roll of band steel setting, away from the live-roller of band steel 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, the counter-rotation that said brush band transmits along the band steel through said live-roller.
As preferably, said cleaning device comprises a casing, is positioned at the band steel in the said casing and is evenly equipped with out sprinkler head in both sides up and down.
As preferably, said water outlet shower nozzle axial direction and belt steel surface are the angle of 45 degree.
Shower nozzle is set and belt steel 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 band steel 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 band steel grit blasting, water under high pressure and high pressure gas; The pressure of supply water of said water under high pressure is 8Mpa; The supply gas pressure of said high pressure gas is 0.7Mpa.
As preferably, said nozzle axial direction and belt steel surface are the angle of 50 degree.
The angle of nozzle setting had not only guaranteed that steel sand, water under high pressure and high pressure gas were sprayed onto belt steel surface and produce enough pressure breakings and dash the effect of removing firecoat but also guaranteeing to wash away.Make the de-scaling of band steel thoroughly also reduce the break flour that adheres to.
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 the band steel is sent into blasting cabinet, successively to band steel 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, need not upset band steel and carry out the reverse side de-scaling, reduced operation and equipment.
The band brush is used to brush a small amount of firecoat break flour and the steel sand that the band steel is left over or also adhered to through upper surface behind the sand blasting unit.
Remove the firecoat of firm attachment through sand blasting unit at belt steel surface; Relatively cleaner through the band steel top layer after the sand blasting unit de-scaling; Lower surface firecoat and steel sand etc. come off under self gravitation totally; Residual a small amount of break flour of upper surface and steel sand are sent into the band brush device and are brushed the residual break flour of band steel upper surface, steel sand and a small amount of firecoat.The removal that thoroughly comes off of firecoat through band steel upper and lower surfaces behind the band brush device.Clean rolling through cleaning device again.
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 belt steel surface grit blasting, water under high pressure and high pressure gas, improve the effect of de-scaling greatly.
2, production is pollution-free, and working environment is safer;
3, de-scaling efficient is high, the band steel article phase of production;
4, the also recyclable utilization of firecoat.
