  • Patent number: 8151728
    Abstract: A gas wiping apparatus for use in coating a molten metal onto a steel strip. In the apparatus, a chamber, to which a high pressure gas is supplied, defines a multistage uniform pressure space. A lip support unit is associated with a front of the chamber to allow the high pressure gas to flow therethrough, the lip support unit supporting the apparatus against load. Upper and lower lips are associated with a front of the lip support unit to cooperatively define an outlet. The upper lip adjusts a gap of a gas outlet cooperatively with the lower lip, and can be easily installed in a lip support unit while adjusting the gap of the gas outlet stably. Also, edge over coating (EOC) of the steel strip can be prevented without an additional auxiliary nozzle.

  • Patent number: 6315029
    Abstract: A continuous casting method, and a device for use in the casting method, are disclosed. The flow state of the discharged molten metal is properly controlled, and thus, the amounts of residual non-metallic inclusions and gas bubbles within the molten metal are decreased, so that continuously cast slabs of a good quality can be produced. The continuous casting device includes a mould with a submerged nozzle installed therein, the submerged nozzle having a pair of discharge holes directed toward narrow faces of the mould. Further, an electromagnetic brake ruler is included for establishing a magnetic field within the mould. The electromagnetic brake ruler includes a base frame surrounding the mould, and iron cores projecting from near the wide faces of the mould, while the iron cores are wound with induction coils.
