Descaler Pump Energy Savings | TMEIC

The high pressure water jets are used to remove scale from the steel bars before they enter the rolling mill. Normally high pressure water is bypassed to the water pit when no bar is present, wasting energy. If the roughing mill is reversing, there are descale nozzles on either side, using even more energy. The energy saving solution is to use a variable frequency drive on the pump motor to ...
