    摘要： To suppress generation of scales on surfaces of a strip and to reduce the amount of non-oxidising gas consumed in the casting of strip in a twin roll caster there is provided downstream apparatus comprising pinch rolls 17a and 17b for pinching a strip 4 continuously cast by a pair of casting rolls 1a and 1b, a coiler 8 for coiling the strip 4 delivered from the pinch rolls 17a and 17b, an upstream chamber 19 for enclosing a travelling path of the strip 4 from the casting rolls 1a and 1b to the pinch rolls 17a and 17b, a downstream chamber 24 for enclosing a travelling path of the strip 4 from the pinch rolls 17a and 17b to a position before the coiler, a shutter on an end of the downstream chamber closer to the coiler and a gas supply source for supplying non-oxidising and reducing gases to the upstream and downstream chambers 19 and 24 and quenching means within the downstream chamber to cool the strip so that it leaves the chamber at a temperature of 300°C or below.

    摘要： A steel strip (12) is continuously cast from a pool (30) of molten metal that is supported on one or more chilled casting surfaces (22A). The casting surfaces (22A) are moved to produce a solidified strip (12) moving away from the casting pool (30) along a transit path (10). The formation of scale on the solidified strip (12) as it passes through the transit path (10) is controlled by confining the solidified strip within an enclosure (37) from which oxygen is extracted by oxidation of the strip and which is sealed to control ingress of oxygen containing atmosphere.
