    摘要: A surface cutting method for a hot-rolled steel product that includes a joint portion having a predetermined breaking strength includes a step of clamping the steel product between a pair of milling cutters that are arranged on top and bottom surfaces of the steel product, while the steel product is conveyed in a longitudinal running direction. The top and bottom surfaces of the steel product are subjected to cutting by rotating the milling cutters in a rotating direction. A cutting resistance applied to the milling cutters during the cutting is determined based on parameters including type of steel, width, thickness, surface temperature and conveying speed of the steel product, as well as circumferential speed and cutting depth of the milling cutters. The cutting resistance is controlled by adjusting the cutting depth of the milling cutters by actuators connected to the milling cutters, such that a tension lower than the breaking strength of the joint portion is applied to the steel product by the cutting resistance, so as to prevent breakage of the joint portion during the cutting.

    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: The invention provides a method for improving the luster of a metal sheet surface without deteriorating the productivity and also in reducing the difference in glossiness between the upper and lower surfaces of the metal sheet at the time of cold-rolling. By making the velocity, after rolling of the metal sheet, equal to or larger than the rotational circumferential velocity of the work rolls, and by rolling the metal sheet with upper and lower work rolls crossed with each other in such manner that an angle of slip scratches left on the metal sheet surfaces becomes 5 degrees or larger and shear deformation in the widthwise direction can be effectively given to the metal sheet just before rolling, thereby improving the surface luster of the metal sheet. In addition, in the case where luster of the metal sheet surface is improved by changing the cross angle between the upper and lower crossing work rolls, the sheet configuration is corrected by a configuration control actuator, depending upon the sheet configuration of the metal sheet after the cross angle is changed. Furthermore, the difference in glossiness between the upper and lower surfaces of the metal sheet is reduced by selecting the cross angles formed by the upper and lower crossing work rolls with respect to the direction at right angles to the rolling direction and also employing rolls having different surface roughness as the upper and lower work rolls.
