摘要： PURPOSE:To accurately control synchronously both opening degree at the rough rolling and to stably roll the stock to be rolled while exactly guiding by operating 2-series side guiding devices while being linked. CONSTITUTION:On the case of the rough rolling that the stock to be rolled is too thick to be wound up by the coiler, the feeding side guiding devices 6, 7 are set, 2 series together, to the opening degree of the stock to be rolled plus the prescribed value of dimension and the exit side guiding devices 6, 7 are set, 2 series together, to the opening degree of the width of the stock to be rolled plus the prescribed value of dimension. When the operation is shifted to the reverse pass after the one pass is finished, the opening degree is reversed and execute rolling. In such a way, the stock to be rolled is fed straightly to the rolling mill while being guided always with the feeding side guiding devices 6, 7 and is rolled.

摘要： PURPOSE:To easily change a 4-stage mill and a 5-stage mill to each other without any essential change of a mill by installing a spindle supporting device bringing a spindle not driving a roll during rolling in the 5-stage mill to be freely rotatable at a roll end of the non-driven roll. CONSTITUTION:As for roll change form a 4-stage mill to a 5-stage mill, a spindle supporting device 11 is connected to a non-driven side spindle 12 by inserting a connecting part 13b of an outside frame 13 into a connecting recessed part 12a of the spindle 12. As the result, the frame 13 is brought to be freely rotatable against a shaft end of a non-driven side roll 10 through bearings 14, 15. Therefore, a spindle coupling 12 is supported and rotated by the device 11 without transmitting power to the non-driven roll. As for change from the 5-stage mill to the 4-stage mill, the device 11 installed at a shaft end of the roll 10 is disconnected from the spindle coupling 12. Thus, roll change is performable without attaching and detaching the spindle 12 for roll changing from the 4-stage mill to the 5-stage mill and for reverse changing.

摘要： PURPOSE:To prevent slippages of height direction and pass direction of a driving side and an operating side housings by arranging a hydraulic cylinder to housing shoe or shifting side housing. CONSTITUTION:Block 14 is retreated by a cylinder 13 and by pushing wheels by a cylinder 13 arranged to the operating side housing 1, the operating side housing 1 is floated and the operating side housing 1 is shifted toward the driving side housing direction by a cylinder 5 held to a bracket fixing to the base by bolts and nuts. The wheels 16 are rotated on a liner 11 having high hardness and fixing on the upper face of the housing shoe 4. Further, as width of the wheel is less than one over several number of contacting width of the operating side housing 1 with the housing shoe 4, even if this width is weared, the fitting height of the operating side housing 1 is not changed.

摘要： PURPOSE:To easily and quickly charge interval between housings by pushing a flange of tension bar and also a spacer to be possible to fitting/detaching to the other housing by working a hydraulic cylinder and fixing to the other housing. CONSTITUTION:In the case of a narrowing interval between the housings, a solenoid valve 40 is turned to T side and a clamp cylinder 24 is retreated and the spacer 23 is made to open-state by working a cylinder. Next, by working a shift cylinder, the shifting side housing 1 is shifted to the fixed side housing 2. Successively, after the spacer 23 is closed by working the cylinder, the solenoid valve 40 is turned to P side and the clamp cylinder 24 is worked, and by pressing the flange part of the tension bar 19 and the spacer 23 to the fixed side housing, the tension bar 19 is fixed to the fixed side housing 2. In this way the shifting side housing 1 is safely fixed to the fixed side housing 2 through the tension bar 19 in a short time without any handworking or crane- operation.
