Abstract

PURPOSE:To prevent the undesirable temperature drop in the rolled material, and to shorten the required time for rolling work, by operating the mill at a fast speed until the tip of rolled material arrives at a specified position in the rolling line. CONSTITUTION:The material being fed to the continuous mill is subjected to a fast speed rolling work at a speed, for example, 1.5-2 times of the finish rolling speed, until the material runs out of the rough rolling 6; hereby, the material quickly arrives at the position P. When the tip of material passes over the position P, an electric signal, etc., is sent to the controlling unit CU, which then produces the slow-down command to respective drivers M1-M6 of the rolling rolls 1-6; hereafter, the material is rolled at a speed corresponding to the finish rolling speed. The intermediate rolling rolls 7-10 standing behind the position P are always operated at a speed equal or corresponding to the finish rolling speed. After the tail end of material passes over the position P, the rolling rolls 1-6 are again returned to the initial high speed preparing for receiving the next material.
