Automatic Cooling Bed
Twin channel bar delivery system will be operated hydraulically. Rack will be operated by AC drives with speed control mechanism to suit the different rolling speed and also for proper cooling. Static grids will be made of cast iron. The rake profile is to be machined to close tolerance, movement of the racks will be through eccentric cam mechanism mounted on the drive shaft. Suitable gear box will be used for drive at suitable speed. Different section of the cooling bed will be synchronized by proper control system.
Rack type cooling bed design depends on bars cut previously to given lengths, to slow them down, to transport them crosswise over a cooling surface ensuring that the rolled bars in very wide range of lengths, are kept straight by aligning rollers, to collect the bars at the end of the cooling surface to predetermined packs matched to the requirements of the cold shear, and to discharge finally same onto a roller table which conveys the bar
