1.5 inches in thickness. Rolling is most often, (particularly in the case of the conversion of an ingot or continuous casting), performed hot. At a rolling mill, blooms and slabs are further rolled down to intermediate parts such as plate, sheet, strip, coil, billets, bars and rods. Many of these products will be the starting material

It is mostly used in rolling mills, elevators, machine tools, etc. This method can be used in both direct current and alternating current and also in induction and synchronous motors. 6.2 Dynamic Braking system:

This method is best suited for steel rolling mills, paper machines, elevators, mine hoists, etc. This method is known as Ward Leonard System. Advantages of Armature Controlled DC Shunt Motor. Very fine speed control over whole range in both directions; Uniform acceleration is obtained; Good speed regulation; It has regenerative braking capacity

⇒ A compound motor is used in Presses, Shears, Conveyors, Elevators, Rolling Mills, Heavy Planners, etc. Why D.C motors are used? While some may claim that direct-current (DC) motors are no longer relevant, that is definitely not the case. DC motors and DC converters/drives are alive and well in the industry. D.C motors have some advantages like

Generally, A.C motors are preferred widely in industries. But when it comes to high starting torque or efficient speed control DC motors are the optimal choice. They are used in aluminum rolling mills, electric elevators, railroad locomotives, and …

Rolling mills; Elevators; Cranes; Paper mills; Diesel-electric locomotives; Mine hoists; Solid State Control or Static Ward Leonard System. Nowadays Static Ward Leonard system is mostly used. In this system, the rotating motor-generator (M-G) set is replaced by a solid-state converter to control the speed of the DC motor.

Rolling mills; Elevators; Frequently Asked Questions on DC Motor. Can a DC motor run on AC? Yes, the DC series motor runs on single-phase AC supply. This is because the torque, which varies as the product of the armature and field current, is always positive. Thus, a positive average torque causes the motor to rotate.
