Pretreatment lines is a process making steel painted with
protective paint and dried after surface ball blast and rust
removal prior to the process of steel. It could improve the
erosion-resistant and fatigue-resistant performance of components
after the boards are processed by pretreatment lines.
Pretreatment line QXY is mainly composed of transportation system,
pre-heating device, ball blast cleaning, paint spraying, drying
system, dust removal and paint fog treatment system and electrical
control system etc. The process width is between 1m and 4m
according to different models. The pretreatment line has been
widely applied for lines such as vessel manufacturing, automobile,
elevator, chemical industry and motorcycle etc.
