    • 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).
    • 在靠近由金属制成的矩形线的最终尺寸的铸造中,随后在水平连续铸造设备中根据DSC方法(直接带铸)将其进一步加工成金属条,铸造产品(4)在 由于钢带的顶部仅通过环境空气的对流和热辐射而被冷却,所以由于不均匀的散热而将其固化到预备条带(5)中,同时所述带材的底部与冷却的金属输送带直接接触 (7)。 以这种方式,铸造产品(4)和金属传送带(7)之间的初始完全接触就会消失,并且铸造产品的带材边缘向上拱起。 为了以简单的方式确保铸造产品(4)与金属输送带(7)的最大接触,从而优化和均衡铸造产品(4)对金属输送带(7)的热传递 本发明提出将压力从上方施加到铸造产品(4)上,通过设置在该铸造件上的压力装置(11)固化到预备条带(5)中,优选地施加到其条形边缘(6) 并且为了补偿离开金属输送带(7)时预备条带的底部突然减少的冷却,预备条带的底部被额外冷却到预定的条带 金属输送带(7)正后方的区域。
