Estimating the term…
In the casting close-to-the final dimension of rectangular strands made of metal and the subsequent further processing thereof into metal strips according to the DSC method (direct strip casting) in a horizontal continuous casting installation the cast product (4) is deformed during the solidification thereof into the preliminary strip (5) due to uneven heat dissipation because the top of the strip is cooled only by convection of ambient air and by heat radiation, while the bottom of said strip is in direct contact with a cooled metal conveyor belt (7). In this manner, the initially complete contact between the cast product (4) and the metal conveyor belt (7) is lost and the strip edges of the cast product arch upwards. In order to ensure in a simple manner maximum contact of the cast product (4) with the metal conveyor belt (7), thus optimizing and equalizing the heat transfer of ht cast product (4) to the metal conveyor belt (7) across the entire casting width, the invention proposes that pressure be applied from above to the cast produce (4) solidifying into the preliminary strip (5), preferably to the strip edges (6) thereof by means of a pressure device (11) disposed at the end of the metal conveyor belt (7) and, in order to compensate for the suddenly reduced cooling of the bottom of the preliminary strip upon leaving the metal conveyor belt (7), that the bottom of the preliminary strip be additionally cooled in a predetermined area directly behind the metal conveyor belt (7).

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,
An apparatus for 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 cast 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 a pressure device (11, 12, 13) arranged above the cast product (4) in a region of a deflection roller (8) of the metal conveyor belt (7) located downstream in a casting direction, is so formed that it applies an adjustable pressure from above to the cast product (4) solidifying into the pre-strip (5),
