    摘要: A rolling method and machine provides for decreasing the rolling load of work rolls of a rolling mill for a given reduction ratio achieved thereby. A pair of pinch rolls upstream of the work rolls have projections that form a large number of recesses in one or both surfaces of a metal workpiece. A lubricating agent is forced into the recesses in the region of contact between the workpiece and the work rolls. As a result, when the workpiece is rolled by the work rolls the lubricating agent is retained in the recesses such that the recesses progressively are flattened, thereby causing the lubricating agent to form a boundary film between the portion of the workpiece being rolled and the work rolls. The recesses are controlled to regulate the dimension of the length of each recess in the direction of rolling of the workpiece, to regulate the inclination of front and rear walls of each recess, and to regulate the total area of the recesses relative to the total surface area of the workpiece.

    摘要: The known belt type continuous casting machine is improved in that a pair of guides for side dam block groups are disposed at opposite sides, in the widthwise direction, of a cast piece. Each of the guides includes guide beams disposed in two parallel rows displaced in direction of the thickness of the cast piece. Each of a pair of side dams which are movable in synchronism with feeding of the cast piece is formed of a side dam block group in one row. Each of the side dam block groups is divided into two sub-groups, each of which has a length longer than a contact length between the side dam block group and the cast piece and each of which is guided by a separate guide beam.

    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.
