Problems solved by technology

This device will not only leave acid and alkali residues on the surface of the steel strip after treatment, which will easily cause corrosion of the material; it will also produce a large amount of waste acid and pickling wastewater, causing serious environmental pollution; It must be treated by neutralization method or filter neutralization method before it can be discharged, which is not only difficult to treat, but also costly

Embodiment Construction

[0036] The steel strip surface treatment method and its device of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0037] as attached figure 1 Shown, a kind of steel strip surface treatment method comprises the following steps:

[0038] (1) The steel strip 9 is uncoiled and conveyed by the feeding roller 8;

[0039] (2) Mechanical descaling: the steel strip 9 is sent into the multi-roller descaling machine 3, and the surface oxide layer of the steel strip 9 is removed through a plurality of upper and lower descaling passive rollers arranged in a staggered manner;

[0040] (3) Leveling, the steel strip 9 after mechanical descaling by the multi-roller descaling machine 3 is sent to the leveling machine 4 for leveling;

[0041] (4) Shot blasting treatment and cleaning: the leveled steel strip 9 is sent to the shot blasting machine 5, projectiles are projected onto the surface of the steel strip 9 at high speed, and the sur...

Abstract

The invention relates to a method and a device for surface processing of a steel belt. The physical method instead of the chemical method adopted in the prior art processes the surface of the steel belt. The method mainly comprises the following steps of: uncoiling of the steel belt, mechanical scale removal, flattening, shot blasting and cleaning, coiling. Corresponding to the steps, the device comprises an uncoiling machine, a welding machine, a multi-roll type scale remover, a flattening machine, a shot blasting cleaning machine, a shearing machine and a coiling machine, which are arranged from front to back in sequence; and conveying rolls for conveying the steel belt are arranged between the uncoiling machine and the welding machine and between the shot blasting cleaning machine and the shearing machine respectively. The device has the advantages of simple structure, good surface processing effect, high cleaning efficiency, safety and environmental protection, low cost, small floor area, long service life of the steel belt and easy population.

Description

technical field [0001] The invention relates to a steel strip surface treatment method and its device, in particular to a steel strip surface treatment method and its device for physically treating the steel strip surface. Background technique [0002] Existing steel strip surface treatment devices all use pickling pools to chemically treat the steel strip surface to remove scale and oil stains attached to the steel strip surface. This device will not only leave acid and alkali residues on the surface of the steel strip after treatment, which will easily cause corrosion of the material; it will also produce a large amount of waste acid and pickling wastewater, causing serious environmental pollution; It is necessary to adopt the neutralization method or filter neutralization method for treatment before discharge, which is not only difficult to control, but also very costly. [0003] With the increasing call for improving the living environment of human beings, the rapid gro...
