Embodiment Construction

[0021] The present invention will be further explained below in conjunction with specific embodiments.

[0022] The present invention proposes a steel plate surface electrolytic descaling process, comprising the following steps:

[0023] S1: The steel strip will be uncoiled by the unwinding trolley, and the steel strip will be uncoiled and pulled by the pressure roller;

[0024] S2: After the uncoiler is uncoiled, the steel strip is sent into the sheller by the pinch roller and the side guide device to peel the steel strip and remove most of the scale on the steel strip. Specifically, the sheller uses five Roller sheller;

[0025] S3: Perform leveling treatment on the steel strip, using a leveling machine for leveling, specifically, the leveling machine uses a five-roller leveling machine;

[0026] S4: Flatten the ends of the steel plate, and use a shearing machine for flattening;

[0027] S5: After the flat end treatment, the steel strip is sent to the steel sand machine b...

Abstract

The invention relates to a steel plate surface electrolysis descaling process which has the advantages that the steel plate surface electrolysis descaling process is good in continuity, short in treatment time, environment-friendly in treatment process and free of wastewater, waste gas or waste liquid, the surface of a treated steel plate is bright, and quality requirements of a product can be completely met. The steel plate surface electrolysis descaling process comprises the following steps: conveying a steel strip to an uncoiler by a coil feeding trolley for uncoiling, and uncoiling and tracking the steel strip to a peeling machine by a pressing roller, peeling the steel strip, and treating most oxide skin on the steel strip; implementing leveling treatment on the steel strip; flattening the heads of two ends of a steel plate; polishing defects of the steel strip by steel grits; washing with clean water for a first time so as to remove stain left on the polished steel strip; feeding the steel strip into an electrolytic bath for corresponding electrolysis operation; after electrolysis, washing with clean water for a second time so as to remove stain left on the steel strip after electrolysis; after washing, drying the steel strip, tracking and conveying the steel strip to a coiler by a S-shaped tension roller, and coiling the steel strip by the coiler.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to an electrolytic descaling process on the surface of a steel plate. Background technique [0002] With the development of thinner steel plate, the descaling treatment area of ​​the steel plate is increasing, and in order to ensure the productivity of the steel plate, it is necessary to realize the high-speed descaling treatment. The current descaling method is outdated, and it takes a long time for descaling treatment. During the treatment process, a certain amount of waste water, waste gas, waste liquid, etc. will be brought, which brings environmental protection problems. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a steel plate surface electrolytic descaling process to solve the above technical problem. [0004] The steel plate surface electrolytic descaling process proposed by the present invention comprise...
