摘要： A method of and an apparatus for controlling a molten metal surface in a mold that are effective to various disturbances are provided. The method and the apparatus for controlling a molten metal surface level in a mold according to the present invention perform the following operations of: measuring the molten metal surface level in the mold of a continuous-casting machine; changing a reference position of oscillation of the mold based on the difference between a molten metal surface setting value set in advance as a desired value of the molten metal surface and a measured value of the molten metal surface level; and making the reference position of oscillation follow molten metal surface fluctuations.

摘要： A rolling mill includes a roll pair, having first and second rolls, for rolling a bar steel, and first and second hydraulic cylinders for moving the first roll relative to the second roll, the first and second hydraulic cylinders being respectively connected to first and second supporting portions rotatably supporting the first roll at both ends thereof. A rolling area for rolling the bar steel, which is set as a partial continuous area in the longitudinal direction of the roll pair, is positioned so that distances from the rolling area to the supporting portions differ from each other, and the rolling mill includes: a distance sensor to measure a roll deflection in the rolling area of at least one of the rolls; and a controller to control the amount of depression of the hydraulic cylinders based on a detection value of the distance sensor.

摘要： A mold oscillator includes: a ball screw unit that has a ball screw 32having a threaded shaft 29 and a ball nut 30, and a nut-side shaft 31 fixed to the ball nut 30 coaxially with the threaded shaft 29, wherein the ball screw unit is positioned so that the central axis of the ball screw unit extends in the vertical direction; and a power transmitting mechanism that transmits rotation to the ball screw unit. Bearings rotatably support a first shaft. A second shaft that is the other of the threaded shaft and the nut-side shaft is connected to the mold side. An attachment portion to fix the mold oscillator at an installation position is provided so as to be immovable relative to the bearings in the vertical direction and is configured to be able to change the relative position between the bearings and the second shall in the vertical direction in a state where operation of the mold oscillator is stopped.

摘要： Provided is a spatter scattering prevention apparatus that eliminates the necessity to, for example, remove scattered spatters and thus makes it possible to facilitate maintenance work, and also provided is a flash butt welder including the spatter scattering prevention apparatus.
The spatter scattering prevention apparatus 1 according to the present invention is characterized by being configured to form a water screen in midair in the vicinity of a welding spot, at which welding is performed, wherein the water screen is for preventing spatters, generated during the welding, from scattering.
The spatter scattering prevention apparatus is also characterized by being configured to form the water screen on one side in a lateral direction of the welding spot and form the water screen on the other side, laterally opposite to the one side, of the welding spot.-
