摘要:
A method for removing loose scale and other foreign matter from the top and/or bottom face of a cast product with the aid of flowable media which are sprayed onto the cast product by a cleaning device having at least one spraying apparatus that is disposed above the cast product and at least one spraying apparatus that is arranged below the cast product. According to the method, the amount of media and/or the effective width and/or the pressure of the media is/are controlled separately and independently of time for each spraying apparatus.
摘要:
The invention concerns a method for producing metal strip (1) in an installation (2), in which a metal strand, especially a thin slab, is brought to a desired temperature and/or is maintained at a desired temperature in a furnace (3, 3a, 3b) and is subjected to a rolling process in a rolling train (4) downstream of the furnace (3, 3a, 3b) in the direction of conveyance (R) of the metal strand (1). In accordance with the invention, to prevent the formation of scale deposits in the downstream region of the furnace, provision is made for the metal strand (1) to be subjected to at least one descaling operation during its residence time in the region (5) of the furnace (3, 3a, 3b). In addition, the invention concerns an installation for producing metal strip.

Disclosed is a method for removing loose scale and other foreign matter from the top and/or bottom face of a cast product (3), such as a slab, thin slab, profiled element, or similar, with the aid of flowable media which are sprayed onto the cast product (3) by means of a cleaning device (5) comprising at least one spraying apparatus (8, 9) that is disposed above the cast product (3) and at least one spraying apparatus (8, 9) that is arranged below the cast product (3). According to said method, the amount of media and/or the effective width and/or the pressure of the media is/are controlled separately and independently of time for each spraying apparatus (8, 9). The invention also relates to a device for removing loose scale and other foreign matter from the top and/or bottom face of a cast product (3) with the aid of flowable media which are sprayed onto the cast product (3) by means of a cleaning device (5) comprising at least one spraying apparatus (8, 9) located above the cast product (3) and at least one spraying apparatus (8, 9) located below the cast product (3). The spraying apparatuses (8, 9) and/or the nozzles (13) that are placed on the spraying apparatuses (8, 9) are configured so as to respond via a controller/a guiding system.
摘要:
A strand pulling-off method for a metal strand, particularly a steel strip, cast in a curved continuous casting plant, wherein the metal strand is initially vertically pulled from a casting mold, wherein a curved shape is then imparted on the metal strand in a curved entry driver driven with an entry torque, and wherein, after reaching a horizontal strand travel direction, the metal strand is finally straightened in a curved exit driver driven with an exit torque. An entry speed is assigned to the curved entry driver and an exit speed is assigned to the curved exit driver, the entry torque and the exit torque are determined, and the exit speed is adjusted in such a way that the entry torque as well as the exit torque have a positive value.
