PURPOSE:To enable always averaged application of pressure even if the number of slabs changes and to stabilize continuous casting in guiding and pressing rolls in a continuous multi-slabs casting of a continuous casting machine by controlling separately on the right and left the pressure application of both bearings of the rolls. CONSTITUTION:If slabs are of the same number on the right and left of press rolls 6a, the hydraulic pressure of hydraulic cylinders 7a, 7b may be the same. If a slab S1 is only at one side, the pressure ratio between the cylinders 7a and 7b is determined at the ratio of the distances l2:l1 up to the center of the slab S1, by which average pressure can be applied on the slab. In such a case, the separate control of the pressure regulating valves of the cylinders 7a, 7b is performed. Since this method can deal immediately with the change in the number of slabs, productivity is improved and the maintenance of equipment is made easy. |
