Description

Turnover mechanism and steel plate processing device with same

Technical Field

The utility model relates to the technical field of steel plate processing, in particular to a turnover mechanism and a steel plate processing device with the same.

Background

After the hot rolled strip steel leaves a factory, the steel coil is blanked and cut into steel plates according to actual requirements. FeO and Fe are adhered to the surface of the steel plate base material due to the hot rolling process of the strip steel₃O₄、Fe₂O₃And the like. In the downstream, when the strip steel is used for cold rolling, stamping, painting and other processes, a relatively smooth and clean strip steel surface is often needed to improve the performance of the product so as to meet the product requirements. Therefore, it is necessary to remove the scale on the surface of the steel sheet. The traditional method for removing the oxide scale from the plate steel is to use a dry shot blasting or acid washing process (hydrochloric acid, sulfuric acid, nitric acid and other strong acids).

In the conventional dry shot blasting, the steel shot or steel grit has large impact force on the surface of the steel plate, so that a surface hardening layer is generated on the surface of the steel plate, and the thin plate cannot be processed because the thin plate can be obviously deformed or damaged after large impact. Meanwhile, part of the oxide skin is remained in the impacted pit, so that the surface descaling effect of the steel plate is poor, the roughness is very high, and the requirements of part of customers on the fine surface of the steel plate after descaling can not be met. In the shot blasting process, a large amount of dust is generated, so that the environment is polluted, and health threats are generated to operating personnel. The traditional dry shot blasting and sand blasting machine has large damage to the equipment, so the later maintenance and use cost is very high.

In the traditional pickling process, due to the chemical reaction of strong acid, a large amount of pollutants such as waste acid and waste gas are discharged and treated, the cost is very high in the treatment of the waste acid and the solid waste at the present stage, so that the operation cost of a normal pickling line is high, and the local soil pickling line has very great damage to the environment due to the fact that the waste acid and the solid waste are not treated.
