Abstract

A mould for continuous casting comprises: (i) a mould tube (14) for receiving molten metal (16); (ii) a cooling circuit surrounding the mould tube (14) for cooling it; (iii) an electromagnetic induction coil (32) for provoking a gyratory movement in the molten metal (16) in the mould tube (14) around its axis, this electromagnetic induction coil (32) being vertically displaceable w.r.t. the mould tube (14); and (iv) a cooling circuit (34, 36) for the electromagnetic induction coil (32). The electromagnetic induction coil (32) with its cooling circuit (34, 36) and the mould tube (14) with its cooling circuit form two separate units. The induction coil unit is mounted around the mould tube unit in a manner that enables it to slide axially as a block along the length of the mould tube (14). The method used to adjust the height of the induction coil unit is also claimed. A crane is used to slide the induction coil (32) unit in some vertical guidance shafts (50) along the length of the mould tube (14) and a mechanical system is used to support the induction coil (32) on the guidance shafts (50) in different predetermined vertical positions. A feature of this continuous casting mould is the use of a source of radiation for constant surveillance of the meniscus of the molten metal in the mould.
