Abstract
The invention provides an apparatus for the continuous casting of metal sheets and bands, including two rotatable roll-crystallizers having parallel axes located in the horizontal plane and defining between them a gap of adjustable width, and means for supplying metal melt to fill the gap; characterized by means for generating at least three substantially horizontal magnetic fields producing electromagnetic pressures adapted to act to contain at least one end face of the melt within the gap.
Claims15
An apparatus for the continuous casting of metal sheets and bands, comprising:
- two rotatable roll-crystallizers having parallel axes located in the horizontal plane and defining between them a gap of adjustable width, and
- means for supplying metal melt to fill said gap;
- characterized by means for generating at least three substantially horizontal magnetic fields producing electromagnetic pressures adapted to act to contain at least one end face of said melt within said gap.
A method for the continuous casting of metal sheets and bands, said method comprising the steps of:
- providing means for generating at least three horizontal magnetic fields, a first, low-frequency, alternating field of a frequency between 5 and 100 Hz, a second, high-frequency, alternating magnetic field of a frequency between 2.5 and 10 kHz, and a third, direct magnetic field;
- providing coolable, counter-rotating rolls defining between them an adjustable gap for determining the thickness of the cast sheets and means for delivering metal melt into said gap;
- coordinating the rate of delivery of said melt, the rate of rotation of said rolls, the rate of cooling of said rolls and the intensity of said magnetic fields;
- switching on said magnetic fields, and
- pouring said melt into said gap.
