Selecting roller table motors for the harshest applications
Roller tables used in modern steel mills tend to use individually driven rollers rather than a single group drive such as a chain or belt. Roller tables require special motors with a high dynamic constant, plus a robust overall design to withstand the extreme heat and dirt of a steel mill. Such motors are used throughout the rolling mill on general conveying duties, but on the reversing mill and associated approach tables, the operating duties are extreme with constant stop/starts and instant reversal of directions. Ananda Majumdar of Regal reviews the key points of this critical technology.
