Abstract
The method of casting near net-shape rectangular strands made of metal and the subsequent further processing the strands into metal strips includes applying pressure from above to the cast product (4) solidifying into the preliminary strip (5), preferably to its strip edges (6) by means of a pressure device (11) disposed at the end of the metal conveyor belt (7) and, additionally cooling of the bottom of the preliminary strip in a predetermined area directly behind the metal conveyor belt (7).
Claims7
A method of casting near-net-shape, rectangular strands from metal and a subsequent processing thereof into metal strips according to a DSC-method (direct strip casting) in a horizontal strip casting installation (1), wherein the metal melt is poured with a melt feeder (3′) on a horizontally circulating metal conveyor belt (7) with a cooled bottom, and a liquid cast product (4) is solidified to a pre-strip on the metal conveyor belt (7) during displacement thereof and which after leaving the metal conveyor belt (7) is fed, mechanically tensioned, to a driver (16) and wherein for establishing a maximum contact of the cast product (4) with the metal conveyor belt (7), a pressure device (11, 12, 13), which is arranged in a region of an end of the metal conveyor belt (7) located downstream in a casting direction, applies pressure to the cast product (4) solidifying into the pre-strip (5) from above,
- characterized in that,
- in order to prevent a possible backward arching of strip edges (6) that can begin in an outlet region of the caster and in order to average heat transfer to the cast product (4) during solidification thereof on the metal conveyor belt (7), a suddenly reduced cooling of a bottom of the pre-strip (5) upon the pre-strip leaving the conveyor belt is compensated, and to this end, in a region, immediately behind the metal conveyor belt (7), a bottom of the pre-strip (5) is additionally cooled.
