摘要： PURPOSE:To reduce the initial setting error of the roll, and to make possible the improvement of the controlling accuracy while the rolling work, by arranging the separate hydraulic cylinders facing each other on both sides of the thrust bearing of the adhusting device. CONSTITUTION:The yoke 13 is opened by detaching the pins 14a, 14b, of the adjusting device, and the block consisting of cylinders 5, 5', and the thrust bearing 4 as one body is incorporated in the chock 2. The roll 1 is incorporated in the chock 2; then the roll 1 and the inner race 4a of the thrust bearing 4 are clamped by clamps 10, 11, tightly to leave no clearance. Suitable pressure is applied to cylinders 5, 5', for setting the roll 1 at the aim position. While the rolling work, cylinders 5, 5', are operated according to the output value of the detector 15, for controlling the position of the end of the roll 1 into constant. Further, the rolling thrust force is operated from the output value, etc., of cylinders 5, 5', and the controlled variable for the position of the roll caliber is operated from the result of above operation and the axial rigidity characteristic. According to this value and the output of the detector 15, the action of cylinders 5, 5', is controlled, for making possible the rolled product with accurate shape and dimension to be obtained.

摘要： PURPOSE:To exchange a coil rapidly by providing a coil terminal fitting/removing device and an automatic fitting/removing device of cooling system. CONSTITUTION:An induction heating coil 1 is mounted on a base 2 in register with a cent ring device 2', and easily detachably fastened with presser metals 3. A booth bar 4 for feeding power to the coil 1 is connected with a booth bar 6, which is wired to a power device 5, through an automatic fitting/removing device 7. The coil 1 is provided with a cooling system comprising a branch pipe 8, header 9, coupler 10, intermediate pipe 11, multi-coupler 12, branch pipe 13, and feed pipe 14; the cooling system can be easily fitted and removed through the use of the multi- coupler 12. The base 2 is mounted on a car track 15, and the truck 15 is run along a rail 19 through the function of a rod 20a and an oil cylinder 20. The position of the ruck 15 is adjusted by an elevating device 16.
