摘要： In a roll changing apparatus of a rolling mill, a stationary roll changing table is provided on a front surface of a work side of the rolling mill. Pull-out rails and upwardly and downwardly movable shift rails are provided on the roll changing table. Shift blocks are provided for detachably attaching to a work roll assembly which has been pulled out, to move the work roll assembly sideways in a shifting direction. Only the work roll assembly to be pulled out can be shifted easily, and replaced with a new work roll assembly without the use of an elaborate foundation structure. Thus, work rolls can be changed swiftly.

摘要： PURPOSE:To prevent any damage such as chipping and cracking from occurring in an angular part of a peripheral edge of a grinding wheel tip face by forming at least either side of both inner and outer circumferential surfaces of the grinding wheel into a tapered surface being tilted to a cylindrical surface in parallel with a shaft center so as to cause radial wall thickness to become smaller in proportion as going toward the grinding wheel tip face. CONSTITUTION:In such a state that a tip end face 18 of a cylindrical grinding wheel is pressed to an outer circumferential surface of a roll, sliding friction is produced in an interval between this roll outer circumferential surface and the grinding wheel, and the roll outer circumferential surface is ground with on-line. At this time, an outer circumferential surface 16 of a stone body 12 is formed into a tapered surface being tilted at an angle alpha (25-40 deg.) to a cylindrical surface in parallel with a shaft center so as to cause radial wall thickness of the stone body 12 to become smaller in proportion as going toward the tip end face 18 being pressed to the roll. In addition, this tip end face 18 is formed into a tapered surface being tilted at an angle theta (0.5-1 deg.) from a plane at a right angle with the shaft center in proportion as going toward the outer circumferential side. In consequence, impact resistance in an angular part 28 of the peripheral edge of this tip end face 18 is well enhanced.

摘要： PURPOSE:To reduce time and labor required to measure a roll profile by equipping a roll profile meter on a roll rearranging truck and by measuring the roll profile at a place adjacent to a rolling stand. CONSTITUTION:The roll rearranging truck 6 is disposed adjacent to the rolling stand, on a pair if rails 15a set on it, work rolls 2, 3 are drawn out. Then, through a roll profile meter supporting device 7 loaded on the other rails 15b, the roll profile meter 8 is set on said work rolls 2, 3. Thus, legs 18a, 18b fixed on a frame 18 of the roll profile meter 8 is abutted on the work rolls 2, 3 to position. In this state, by a displacement sensor 16 of contacting or non- contacting types and a surface thermometer 16a, the roll profile and a surface temp. of the roll are measured. In this way, the roll profile is measured quickly at the position adjacent to the rolling stand.

摘要： PURPOSE:To improve the mechanical property of a grinding wheel as well as prevent any damage such as chipping and cracking in an angular part of a tip face peripheral edge of the grinding wheel irrespective of vibration in a roll by mixing a short fiber in the stone uniformly. CONSTITUTION:In such a state that a tip face 12 of a grinding wheel 10 is pressed to an outer circumferential surface of a roll, sliding friction is produce din an interval between this roll outer circumferential surface and the grinding wheel 10, and the roll outer circumferential surface is ground by the grinding wheel 10 with on-line. At this time, short fibers is uniformly dispersed and mixed in the grinding wheel 10, and mechanical property of this grinding wheel 10 is enhanced. With this, any damage such as chipping (defective) and cracking or the like is prevented from occurring in an angular part of a tip face peripheral edge of the grinding wheel 10 irrespective of vibration in the roll, and a collision between irregularities existing on the roll outer circumferential surface and the grinding wheel 10.
