Introduction
JPG steel pre-treating shot blasting machine is also called steel sheet shot-blasting pre-treatment line. After surface shot blasting, the machine will paint a protective primer painting for the steel plate. This steel plate pretreatment line consists of lateral hydraulic pressure feeder and blanker, feeding and blanking roller bed, shot blast system, dust removing system and electrical control system.
Applications
JPG steel sheet shot-blasting pre-treatment line is applied to remove the rust, oxide scale and contamination on the steel surface so as to make the surface clean and bright but with certain coarseness. This steel plate pretreatment line can also make the paint film attach to the steel surface more firmly. Thus the surface quality and the anti-corrosion capacity of products will be improved.
Features
-
JPG steel sheet shot-blasting pre-treatment line, with a total length of 30 m, is designed and manufactured based on decades of experience in this field.
-
Steel descaled by this steel plate pretreatment line can prolong die life, improve burning, welding and machining operations, and provide the proper surface finish for the application of modern coatings.
-
In the electric central controlling room, there’s a LCD touch screen that can control the working status and indicate the error if there is warning.
-
The full steel sheet shot-blasting pre-treatment line is centrally controlled by Industrial Personal Computer (IPC).
-
This steel plate pretreatment line is mainly used in the field of shipbuilding, locomotive, antiseptic project and bridge construction industries.
