speed regulator for reversing mill

DC Motor Speed Control - DCAClab Blog

Jan 3, 2021The output voltage of G is directly fed to the main motor M1. The voltage of the generator can be varied from zero up to its maximum value by means of its field regulator. By reversing the direction of the field current of G by means of the reversing switch RS, the generated voltage can be reversed and hence the direction of rotation of M1.

What is a Reversing Mill? - Definition from Corrosionpedia

The purpose of the reversing mill is to reduce the thickness of the steel to the customer's specifications. The hot roll band passes back and forth between the rolls until it reaches the specified thickness. Benefits of reversing mills include: Flexible, low-cost rolling of a wide range of products. Tight strip thickness and shape tolerances.
