Abstract

PURPOSE:To obtain good quality rolled metal which is excellent in strength, tenacity, and weldability by controlling the cooling and sending of rolled metal so that the surface temperature of rolled metal when entering into rolling mill on the outlet side after cooling is a target temperature when its temperature is restored to a steady distribution. CONSTITUTION:The temperature on the outlet side of the inlet side rolling mill 1a is given by the actvally measured temperature or predicted temperature of the thermometer 6a, and required sending time to the cooler 3 is determined by the sending speed from the arithmetic command device 4 accoding to rolling pitch or the condition of the outlet side rolling mill 1b. The temperature when it is fed to the cooler 3, the temperature immediately after it is cooled, and the time of cooling are operated, and then according to the cooling time, the time required for the non- steady distribution of temperature produced by cooling to reach a steady distribution, or a heat restoration time, is operated. By comparing the heat restoration time with the required time to send from the cooler 3 to the outlet side rolling mill 1b, a cooling time is commanded to the cooler 3 and also a sending speed is commanded to the feeder 5 by the arithmetic command device 4.
