During a hot‑rolling line, the moment a strip leaves the finishing stand, precise timing is required to keep the tension within safe limits and to synchronize the downstream straightening units. The Ditec WS controller provides the real‑time logic that governs the drive motors of the tension rollers, automatically adjusting speed as the strip accelerates or decelerates. By interfacing directly with the plant’s PLC network, it translates process commands into motion profiles, allowing the line to react within fractions of a second to variations in material thickness or temperature. Operators can program the controller to execute predefined start‑up and shut‑down sequences, reducing the risk of sudden load spikes that could damage the roll bearings. In practice, the controller is mounted in the drive cabinet of a continuous‑casting caster, where it coordinates the pull‑in rollers with the furnace feed system, guaranteeing a smooth feed into the rolling mill. This capability makes the WS controller indispensable for maintaining product quality and line availability in modern steel mills.
