China Heavy Duty Steel Rolling Mill DC Motor, Find details about China DC Motor, Motor from Heavy Duty Steel Rolling Mill DC Motor - Shanghai Fortune Electric Co., Ltd.
The starting torque of DC shunt motor is doesn't high as DC series motor but its speed is nearly constant for no load and full load. Now, in rolling mills require high starting torque but the load may be sudden get off, in that case both DC series and DC shunt motor is not use.
The mill was driven by a 12 kW DC motor, through a four-speed gearbox. The top surface speed of the rolls was 1100 mm/s. The surfaces of the 150 mm diameter, 203 mm long tool steel rolls were sandblasted, creating random roughness of R a =0.3 μm.

Rolling mill DC motors are best at low speed, high torque applications, while AC motors typically need to run above 800rpm to be cost effective. Also the case for higher efficiency of AC motors is many times negated by the wasteful braking methods of some AC drive systems. All this being said, for motors below 200-300kW, or when new products ...
Steel Rolling Mill, Neural Network s, DC-Motor speed . control, and Multimachine contro l. Introduction . Steel production is still one of the major basic industries .
Rolling mills usually run around the clock, and DC motors may cause downtime and are expensive to maintain such as the continuous need to be machined, and of course, the brushes wear. However, the amount of maintenance on a DC motor, if maintained properly, can be infinitesimal. An advantage of an AC to DC drive or rectifier is the cost.
