<p>A duel roll casting machine capable of reducing the supply amount of inert gas for oxidation prevention, comprising an enclosing casing (5) surrounding a strip (3) between cooling rolls (1) and pinch rolls (4), a swing wall (13) disposed in the enclosing casing (5) and having a tip part moving close to and apart from one face of the strip (3), a seal roll (14) pivoted at the tip of the swing wall (13), a swing wall (15) disposed in the enclosing casing (5) and having a tip part moving close to and apart from the other face of the strip (3), a seal roll (16) pivoted at the tip of the swing wall (15), a seal member (54) installed between the peripheral edge parts of the swing walls (13) and (15) and the inner side face of the enclosing casing (5), and pipelines (74), (75), and (76) for feeding the inert gas (G) into the enclosing casing (5), wherein the swing walls (13) and (15) are rotated so that the seal rolls (14) and (16) are positioned near the strip (3) to suppress the flowing of the inert gas (G) from a space (72) into a space (71).</p> |
