    摘要： In a tandem mill system, at least one first type rolling mill is arranged in the upstream side and at least one second type rolling mill is arranged in the downstream side. The first type rolling mill is of the so-called work roll crossing mill in which a pair of work rolls are inclined with respect to a pair of back-up rolls supporting the work rolls and simultaneously crossed each other in a horizontal plane to control transverse thickness distribution of a strip. The second type rolling mill is of the so-called HC mill which controls the strip crown and shape by a combination of axial movement of intermediate rolls and work roll bending. Such an arrangement makes it possible to increase a capability of controlling the strip crown and shape, particularly, a capability of correcting the quarter buckle, and eliminate a fear of causing scratches on the strip and roll surfaces, with the result of improved production efficiency. Plural lines of lubricant supply device are also provided to stop supply of a lubricant immediately before biting of the strip into the work roll crossing mill and start the supply again after the biting. A system of lubricating the work roll crossing mill is thereby improved.

    摘要： A steam turbine comprises a rotor with moving blades attached thereto; diaphragms which surround the rotor from an outer periphery side of the rotor; a casing which encloses the diaphragms and the rotor and has an upper half and a lower half clamped together through respective flanges; a displacement detector for measuring a difference d in thermal expansion in the rotor axis direction between the casing and the rotor; heating/cooling devices attached to the flanges respectively to heat and cool the flanges; and a controller which makes control so that the flanges are heated or cooled by the heating/cooling devices until a measured value obtained by the displacement detector reaches a preset value M or S in unsteady operation.

    摘要： A sealing structure in which free-cutting spacers on a sealing base plate and sealing fins on a rotor are opposed to each other is provided. The sealing base plate is disposed so as to be movable in an axial direction of the rotor. When a steam turbine increases in load, a pressure head moves in an axial steam-pressure loading direction of the rotor and the sealing base plate connected to the pressure head moves in the axial steam-pressure loading direction. Since the free-cutting spacers at positions opposed to those of the sealing fins existing after the movement of the sealing base plate are maintained in a non-contact state, clearances between the sealing fins and the free-cutting spacers are dimensionally minimized.

    摘要： To eliminate a vertically asymmetrical deflection, a rolling mill comprises a device for measuring horizontal deflections of upper and lower work rolls 2, 3 during rolling, a device for comparing values measured on the upper and lower sides and calculating the difference therebetween, and a horizontal deflection controller four determining whether the difference exceeds a predetermined range or not and imparting a horizontal bending to at least one of the work rolls. To eliminate a transversely asymmetrical deflection, a rolling mill comprises a device for measuring horizontal deflections of at least one of the work rolls at axially spaced positions during rolling, a device for comparing values measured on at the axially spaced positions and calculating the difference therebetween, and a horizontal deflection controller for determining whether the difference exceeds a predetermined range or not and imparting a horizontal bending to the one work roll at least one of the axially spaced positions. This prevents an adverse effect by the work rolls being horizontally deflected in a vertically or transversely asymmetrical way, reduces the diameter of the work rolls, and increases the allowable rolling load. Stable rolling of high-quality strips with good shape or flatness is thus achieved.
