To improve the productivity of the cold rolling facility by providing the cold rolling facility with a strip wiper free of dust and foreign matters suitable for high-speed rolling. The wiping ability was greatly improved by floating and supporting the wiper roll by the static pressure bearing of air of two-pocket type, and by variably adjusting the load range of the floating force in response to the plate width. At high-speed rolling exceeding 700 m/min which was incapable with the conventional roll wiper or tube wiper, the productivity of the cold rolling facility and the surface quality of the strip were greatly improved by applying to the cold rolling facility the wiping device whose wiping ability is equal to or better than the tube wiper at low speeds, and its effect is very large.
A strip wiper device to remove liquid from a strip surface which comprises:
A strip wiper device to remove liquid from a strip surface which comprises a first strip wiper and a second strip wiper which are arranged sequentially in the direction of strip advance, the second strip wiper being made up of:
A strip wiper device to remove liquid from a strip surface in cold rolling which comprises a first strip wiper for rough wiping and a second strip wiper for finishing which are arranged sequentially in the direction of strip advance, the second strip wiper being made up of:
A strip wiper device to remove liquid from a strip surface which comprises a first strip wiper and a second strip wiper which are arranged sequentially in the direction of strip advance, the first and second strip wipers each being made up of a wiper roll and a fluid bearing to support the wiper roll, with the fluid bearing having at least two fluid passages in the circumferential direction of the roll, and
A strip wiper device to remove liquid from a strip surface which comprises a first strip wiper and a second strip wiper which are arranged sequentially in the direction of strip advance, the second strip wiper being made up of a wiper roll and a fluid bearing to support the wiper roll;
A method of strip wiping to remove liquid from a strip surface which is characterized in that wiper rolls supported by fluid bearings are arranged above and below the strip surface, with the respective fluid bearings having at least two fluid passages in the circumferential direction of the roll, the fluid passages being supplied with a fluid so that the wiper roll is borne by the fluid and is pressed against the strip;
A method of strip wiping to remove liquid from a strip surface of a strip which is characterized in that a wiper roll for rough wiping removes liquid from the strip surface and wiper rolls supported by fluid bearings are arranged above and below the strip at the downstream side, with the fluid bearings having at least two fluid passages in the circumferential direction of the roll, the fluid passages being supplied with a fluid so that the wiper roll is borne by the fluid and is pressed against the strip;
A rolling facility which comprises a rolling mill and a strip wiper device to remove liquid from the strip surface at the exit of the rolling mill, said strip wiper device being made up of a wiper roll to remove liquid from the strip surface, a fluid bearing to support the wiper roll, with the fluid bearing having at least two fluid passages in the circumferential direction of the roll;
A rolling method to be applied to a rolling facility made up of a rolling mill and a strip wiper device to remove liquid from a strip surface at the exit of the rolling mill, said method being characterized in that wiper rolls supported by fluid bearings are arranged over and under the strip, the fluid bearings having at least two fluid passages in a circumferential direction of the roll and the passages are supplied with a fluid so that the wiper roll is borne by the fluid, and the wiper roll is pressed against the strip so that liquid is removed from the strip surface while rolling is carried out;
A rolling method to be applied to a rolling facility made up of a rolling mill and a strip wiper device to remove liquid from a strip surface at the exit of the rolling mill, said method being characterized in that a wiper roll for rough wiping removes most liquid from the strip surface, wiper rolls supported by fluid bearings are arranged over and under the strip, the fluid bearings having at least two fluid passages in a circumferential direction of the roll and the passages are supplied with a fluid so that the wiper roll is supported in two directions by pneumatic pressure, and the wiper roll is pressed against the strip so that liquid remaining unremoved by the wiper for rough wiping is removed from the strip surface while rolling is carried out;
A strip wiper device which comprises:
A strip wiper device which comprises:
A strip wiper device which comprises:
A method of making strip material comprising:
