Steel plate derusting production line

Abstract

The invention relates to a steel plate derusting production line. The steel plate derusting production line comprises a plurality of steel plate surface derusting machines and a plurality of steel plate side surface derusting machines which are arranged in the moving direction of the production line and a trolley rail which is parallelly arranged on one side of the production line; at least one roller changing trolley which can slide along the rail back and forth along the rail is arranged on the trolley rail; a roller changing mechanism is arranged on the roller changing trolley; and when thetrolley moves to the front side surface of a steel plate surface derusting machine, the roller changing mechanism can extend into the steel plate surface derusting machine for roller changing operation. According to the steel plate derusting production line, a steel plate is subjected to surface derusting treatment by adopting a physical derusting mode; pollution is little; the derusting efficiency is high; the surface of the steel plate can be derusted seamlessly; meanwhile, a damaged roller in the steel plate surface derusting machines is automatically changed through the roller changing trolley, so that the automation level is high; and time and labor are saved.

Description

technical field [0001] The invention belongs to the technical field of metal surface treatment, in particular to a steel plate derusting production line. Background technique [0002] It often takes a period of time before the steel plate is produced to the actual use. During this period, due to various reasons, the surface of the steel plate will be rusted, which will affect the actual use. Therefore, it is necessary to derust the surface of the steel plate before using it. deal with. [0003] At present, the method for removing rust on the surface of steel plates is generally pickling and rust removal. The principle is to use the acid in the pickling solution to chemically react with the metal oxide to dissolve the metal oxide and remove the rust and dirt on the steel surface. However, after the steel plate is pickled and derusted, it must be cleaned with a large amount of water and passivated. The large amount of waste water, waste acid, and acid mist formed by it will ...

Problems solved by technology

[0004] Of course, there are also some physical rust removal methods. At present, the rust removal and polishing process on the steel plate surface in this technical field uses a disc brush or an abrasive belt rust removal mechanical device. Poor, the efficiency of rust removal is low and the surface of the steel plate cannot be fully cleaned; on the other hand, when the disc brush or the abrasive belt needs to be replaced due to wear and tear, it often requires manual operation for a long time, which is time-consuming and laborious
