  • Control Of Metal Rolling (AREA)

Abstract

PURPOSE: To greatly extend the range of adjustable, controllable width of the strip, by installing the heater-conservator and the cooler in the strip-tension controlling zone on the process line.
CONSTITUTION: The multiple unit controller 16 produces previously set temperature control command signal 22, cooling temperature command signal 24 and tension command signal 21 correspondingly to the traveling speed 30, width and thickness, and the class of steel, of the material 1 passing through the rolling line. The strip is heated to and conserved at a specified temperature by the heater-conservators 4, 5. In this conservator 5, the measuring point for the intermediate sheet width is fixed and the width meter 7 is installed there. According to the temperature control command signal 22, the temperature of the strip in the heater-conservators 4, 5, is controlled to the command temperature by the heating controller 12. According to the cooling temperature command signal 24, the cooling controller 13 cools the strip following to the commanded cooling pattern by the cooler 6; at the same time, according to the cooling starting position command signal 23, the cooling controller 13 controls the cooling starting position.
