Abstract

The utility model provides a steel strip surface descaling device which is pollution-free and good in descaling effect, and a steel strip processed through the steel strip surface descaling device has good surface quality. The steel strip surface descaling device comprises an abrasive blasting descaling device, a brush roll device and a low-pressure descaling device, which are arranged in sequence. Four to eight abrasive blasting nozzles are arranged inside the abrasive blasting descaling device and are evenly distributed at the two sides of the steel strip, and the angle between the abrasive blasting nozzles and the advancing direction of the steel strip is 45-60 degrees. Six to eight low-pressure nozzles are arranged inside the low-pressure descaling device and are located at the two sides of the steel strip, the angle between the axial direction of the low-pressure nozzles and the advancing direction of the steel strip is 30-45degrees, and in addition, the pressure of the water ejected by the low-pressure nozzles is 500-1000KPa.

Description

A kind of steel strip surface descaling device
Technical field
The utility model relates to a kind of descaling device, relates in particular to a kind of steel strip surface descaling device.
Background technology
Steel band is in heat treatment process, the ferro element generation oxidation reaction of the oxygen in the heating furnace, water and carbon dioxide and steel strip surface layer, form iron scale on the surface, it is firecoat, before steel band is rolled, must remove the iron scale of steel strip surface, the effect of de-scaling directly has influence on the final quality of product.
The normal method that adopts machinery and pickling to combine in the prior art, and when using abrasive material that steel surface is carried out Shot Blasting, large to the steel strip surface quality influence, and when using acid dip pickle, the acid mist pollution that produces in the production process is serious, and device is corroded seriously.
In addition, use high hydraulic pressure that steel band is carried out de-scaling in the existing apparatus, need to consume a large amount of water resources, and high-pressure water device need to be provided, cause production cost to improve, the device loss is large.
Summary of the invention
The purpose of this utility model be for address the above problem provide a kind of pollution-free, scale removal effect good, process the measured steel strip surface descaling device of rear surface matter.
The utility model is achieved by the following technical programs: a kind of steel strip surface descaling device comprises the Sand blasting descaling device, brush roll arrangement and the low pressure descaling device that set gradually.
Be provided with 4-8 sandblast nozzle in the described Sand blasting descaling device, and the sandblast nozzle is evenly distributed on the both sides of steel band, and the angle of steel band direction of advance is between 45-60 °.
Be provided with 6-8 low pressure shower nozzle in the described low pressure descaling device, and the low pressure shower nozzle is positioned at the steel band both sides, and the angle of low pressure shower nozzle axial direction and steel band direction of advance is between 30-45 °, and in addition, the hydraulic pressure of low pressure shower nozzle ejection is between 500-1000 kPa.
The angle of sandblast nozzle setting both can guarantee that steel sand was sprayed onto steel strip surface and can produces the punching of enough pressure breaking except firecoat in the Sand blasting descaling device, can guarantee again simultaneously to make the effect of washing away the steel band de-scaling thoroughly and reduce the break flour that adheres to.
From Sand blasting descaling device steel band out, because the Sand blasting descaling device has been removed the firecoat of firm attachment in steel strip surface, cleaner by the steel band top layer after the de-scaling of Sand blasting descaling device, but has certain roughness, and some steel sands of residual embedding, throw the brush steel strip surface through brush roll arrangement again, make steel strip surface smooth.
Use the reason of low pressure descaling device to be, because water jet makes the mechanism of steel strip surface oxide skin fragmentation much larger than water jet to the fuel factor of oxide skin cooling, therefore, replace high hydraulic pressure to have huge economic advantages with low hydraulic pressure, and can't affect the de-scaling quality.
In sum, the utlity model has following beneficial effect: 1, multiple de-scaling mode is combined, can increase substantially the effect of de-scaling; 2, throw the brush steel band through brush roll arrangement, the steel band quality is good, and reaches the effect of euphotic belt; 3, use low-pressure water to carry out de-scaling, can reduce the production cost of device, produce great economic benefit; 4, the environmental pollution of having avoided pickling to cause, more environmental protection.
