Apparatus for controlling the temperature of rods in a continuous rolling mill

Abstract

An apparatus for controlling the temperature of a material being rolled into a rod in a rod rolling line having a continuous rolling mill with a first thermometer located at an inlet thereof, a plurality of water cooling units located at an outlet thereof and having an adjustable cooling water flow rate, and a laying head for winding the rod, the laying head having a second thermometer located at an outlet thereof. The apparatus comprises an arithmetic device for computing the rate of flow of cooling water based on a rolling schedule for the continuous rolling mill, an expected temperature at an inlet of the continuous rolling mill, and a target temperature at the laying head, and a control device responsive to a result of computation by the arithmetic device for controlling the rate of flow of cooling water.
