Galvanized steel sheet surface pretreatment equipment and pretreatment process thereof

Abstract

The invention discloses galvanized steel sheet surface pretreatment equipment and a pretreatment process thereof, and belongs to the technical field of metal surface treatment. The galvanized steel sheet surface pretreatment equipment comprises a base, and the top of the base is fixedly connected with a first side plate seat. According to the equipment, through the mutual cooperation of the designed structures such as a first hydraulic cylinder, a second hydraulic cylinder, a first lifting seat, a second lifting seat, a buffer spring, a buffer plate, a descaling device, a movable sealing device, a microwave chamber, an air pump, a microwave generator, a first rotating shaft, a driving roller, a first motor and the like, greases on the surface of a steel sheet are evaporated. Other attachments are separated due to drying, the drainage effect of the air pump is assisted, so that the greases on the surface of the steel sheet and the other attachments can be effectively removed, the precision of subsequent polishing machining is guaranteed, the surface of the steel sheet is clamped and fixed in the polishing process, and the stability of the steel sheet is effectively guaranteed. The problem that the steel sheet deforms due to uneven stress in the polishing process, and consequently the polishing effect is poor is solved.

Description

technical field [0001] The invention belongs to the technical field of metal surface treatment, and in particular relates to a galvanized steel sheet surface pretreatment equipment and a pretreatment process thereof. Background technique [0002] Galvanized steel sheet is a welded steel sheet with a hot-dip galvanized or electro-galvanized layer on the surface. It is generally widely used in construction, home appliances, vehicles and ships, container manufacturing, and electromechanical industries. [0003] Before hot-dip galvanizing, the surface of the steel plate needs to be pre-processed to remove harmful substances such as scale, burrs, and oil stains on the surface of the steel plate. At present, the traditional steel plate pretreatment equipment mostly uses chemicals to remove oil stains. Washing, then cleaning with clean water, and finally drying treatment, the cost is high, and it is easy to generate a large amount of chemical wastewater, which is not good for envir...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the problem that traditional steel plate pretreatment equipment usually uses chemicals to wash off oil stains, then cleans them with clean water, and finally performs drying treatment, which has high cost and is prone to produce a large amount of oil. Chemical wastewater is unfavorable to environmental protection, and grinding is often used to remove scale and burrs on the surface. However, during the grinding process, vibrations easily occur between the steel plate and the grinding equipment, which in turn will affect the steel plate. The problem of surface levelness, and proposed a galvanized steel surface pretreatment equipment and its pretreatment process
