A New Approach to Cold Mill Drive Equipment Air Cooling

Dominion Foundries and Steel Limited (DOFASCO) of Hamilton, ON, commenced single-shift production on the new No. 2 Five-stand Cold Rolling Mill in July 1976. The mill employs a new integrated systems approach to the cooling of the mill drive motors, associated electrical control equipment, mill process and service areas, and buildings. The new approach represents an improvement in cold rolling mill electrical equipment cooling and ventilating methods. As described, the new approach results in cost and operating advantages over established methods.
