Plate conveying system
The whole plate conveying system is driven by frequency converter motors that carry out the stepless speed adjusting. Every working part can run synchronously as well as individually. The three rollers in the flame area inside the pre-heating cabinet are cooled by water. The rollers inside the blasting cabinet are protected by special protecting sleeves. The line equips with the heavy-duty apron chain conveyor. On one side of the inlet roller conveyor, the aligning column-rollers are installed.
Pre-heating cabinet
Equips with overheat protecting device and explosion-proof device.
Shot blasting cleaning
The plate detecting device is located in front of the
blasting cabinet, thus prevented the interference caused by abrasive and dust.
Abrasive sweeping
To completely clean the top surfaces of the steel plates, we adopt the two-stage sweeping and two-stage air blowing.
Primary sweeping: High strength Nylon rolling brush + abrasive collecting screw
Secondary sweeping: Side brush + Guide wheels
Primary air blowing: High-pressure ventilator blows inside the blasting cabinet
Secondary air blowing: Compressed air complementarily blows outside (or inside) the cabinet
Electric control system
The whole line is controlled by programmable logical controller (PLC), Distributed controlling desks are located at suitable positions. As an option, the system can be equipped with the software of
Steel plate pretreatment line, dynamic simulating and monitoring system (controlling center)
