This series is a kind of multifunctional steel pretreatment equipment for steel plate and profile steel. The blast wheel is multi-oriented and high-efficient adopting word- advanced unit serpentine curve blades, it could throw high-speed and dense shots, which hit on each position of steel plate in original state, to clean soiled and all-directionally, make rust layers, welding slag, roll scale and feculence on surface of steel plate shed quickly and obtain smooth surface with certain roughness, which will improve adhesive strength between the paint film and steel surface, promote fatigue strength and corrosion resistance improve the inherent quality of steel and prolong its use life.
Steel pretreatment line is mostly consisted of horizontal feed device, entry table, preheating chamber, shot blast machine, transient table, paint spraying machine, drying chamber, runoff table, horizontal cutting device, dust cleaning series, paint disposing system and electricity, etc.
1.Roll Table
3.Shot Blast:
4.Paint Spraying:
5.Drying
6.Paint Mist Treatment: this system has two treatment forms, that is, dry type and wet type and wet type. Gas after treatment is discharged to the high sky, the concentration of three benzene organic solvent discharged should be in accordance with national emission standards for environmental protection.
7,Electrcity: electric control system of the whole line adopts PLC programmable controller with manual and automatic controlling forms. In addition, the system has central control room, electric control room, operating tables, separate control table and separate control cabinet, the control table is installed with analog screen to reveal working state of the whole line, benefiting observation and control of the whole line and promotion of work efficiency.
