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. It further includes a pair of electromagnetic transferring parts connected to the iron cores, and disposed immediately above the discharge holes of the submerged nozzle toward narrow faces of the mould and in parallel with a discharge direction of the molten metal. With the magnetic field applied within the mould, the separation capability for the non-metallic inclusions and gas bubbles is increased so as to greatly reduce the internal defects of the cast products.
