Description
Technical field
The utility model relates to a kind of purging system, relates in particular to a kind of steel band and allowances for bark purging system.
Background technology
Because rolling technological parameter is subject to the impact of the factors such as cooling velocity, steel band composition and temperature, cause formed scale structure in course of hot rolling to present larger otherness.Because the generation of iron scale can cause metal consume; Iron scale can produce the mass defects such as pockmark and spot after being pressed into hot rolled strip surface.Analysis and research are removed the effective ways of iron scale and iron scale and are formed mechanism and have and do not allow the function and significance despised.
The tradition method of descaling is that steel are immersed in multiple acid solution and carry out pickling, and this acid washing method is difficult to meet the requirements of the fineness of cleaning effect and steel surface.In acid cleaning process, also inevitably produce overpickling and steel hydrogen embrittlement, steel loss is large.The acid mist that pickling produces causes very large injury to human body, and it is large that the spent acid after pickling is processed investment, and occupation of land is many, contaminated environment, and acid solution is had relatively high expectations to production equipment simultaneously, and loss is larger.
Utility model content
The utility model is mainly to solve the deficiencies in the prior art, and a kind of compact conformation is provided, and the feature of environmental protection is good, and steel loss is few, descales thoroughly, and the steel band of steel quality light is allowanced for bark purging system.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of steel band is allowanced for bark purging system, comprise the steel coil strip that is wound with steel band, described steel band passes through dejacketer successively, sand blasting unit, brush roll arrangement and cleaning device, steel coil strip is in wrap-up, described dejacketer comprises decortication row roller, middle decortication row's roller and lower decortication row roller, the side of described upper decortication row roller distributes with the side phase bending of middle decortication row roller, another side of described middle decortication row roller and the side phase bending of lower decortication row roller distribute, the outside of described upper decortication row roller is provided with location decortication row roller, described steel band is successively by upper decortication row roller, middle decortication row roller, lower decortication row's roller and upper location decortication row roller,
Described sand blasting unit comprises sand tank and nozzle, and described sand tank is connected with nozzle by blast tube, and one end of described nozzle is connected with air hose, the distribution corresponding with nozzle of described steel band;
Described brush roll arrangement is comprised of the nip rolls of continuous distributed, and described nip rolls is comprised of pinch upper roll and pinch under roll, and described steel band is by between pinch upper roll and pinch under roll.
As preferably, described upper decortication row roller, middle decortication row roller, lower decortication row's roller and upper location decortication row roller are respectively stainless steel rider.
In described dejacketer, respectively arrange the both sides that roller is arranged on steel band, through repeatedly turning to bending, the pressure that the stress that bending process produces and roller are applied on steel band comes off the oxide layer fragmentation that is attached to steel strip surface.
Each arranges roller is stainless steel rider.Row's roller one is provided with gear hobbing.The pressure when tooth on roller has strengthened steel band and roller contact, makes oxide skin more easily broken.
Sand blasting unit comprises a plurality of nozzles; Described nozzle is distributed in the both sides of steel band.Sand blasting unit is by nozzle to steel band grit blasting, water under high pressure and high pressure gas, and the pressure of supply water of water under high pressure is 10Mpa, and the supply gas pressure of high pressure gas is 0.8Mpa.Nozzle axial direction and steel strip surface are the angle of 30-60 degree.Certain angle washes away the oxide skin coming off in the same direction, the angle arranging had both guaranteed that steel sand, water under high pressure and high pressure gas were sprayed onto steel strip surface and produce enough pressure breaking punchings and descale, guarantee again scouring effect, steel band is descaled thoroughly and reduce the break flour adhering to.
Cleaning device comprises a casing, and casing is positioned at the upper and lower both sides of steel band, and is evenly equipped with water outlet nozzle; Water outlet nozzle axial direction and steel strip surface are the angle of 45 degree, and oxide skin break flour is rinsed out towards a direction with current, and flushing surface is larger, rinse the better effects if that descales; The angle of 45 degree is set, makes current be difficult for falling back to the nozzle of steel band bottom, prevent plug nozzle, assurance upper and lower surface is rinsed simultaneously.
Steel band after dejacketer, the most of oxide skin in top layer is rolled broken coming off, through sand blasting unit, remove the residual oxide skin that is attached to steel strip surface again, steel band top layer after descaling by sand blasting unit is cleaner, but there is certain roughness, and more residual steel sands, through brush roll arrangement, throw brush steel strip surface, make steel strip surface smooth, further remove oxide skin and a small amount of steel sand simultaneously.By cleaning device, clean again and wrap-up rolling.Through the cooperation of above multiple working procedure, the steel band oxide layer after processing is removed thoroughly, surface-brightening.
Therefore, steel band of the present utility model is allowanced for bark purging system, compact conformation, adopt the mode of full mechanical removing oxidized scale, the environmental pollution of having avoided pickling to cause, is used in conjunction with through multiple working procedure, steel band is thoroughly descaling in without pickling situation, surface-brightening, steady quality.
