DUAL ROLL CASTING MACHINE

摘要

A twin roll casting machine is provided which can reduce an amount of inert gas to be fed for prevention of oxidization. <??>It has an enclosure 5 enclosing a strip 3 in a range from chilled rolls 1 to pinch rolls 4, a swing wall 13 within the enclosure 5 and having a tip end movable toward and away from a surface of the strip 3, a sealing roll 14 rotatably supported by the tip end of the swing wall 13, a swing wall 15 within the enclosure 5 and having a tip end movable toward and away from the other surface of the strip 3, a sealing roll 16 rotatably supported by the tip end of the swing wall 15, sealing members 54 between peripheral edges of the swing walls 13 and 15 and an inner surface of the enclosure 5, and conduits 74, 75 and 76 for supplying inert gas G into the enclosure 5. The respective swing walls 13 and 15 are swung to bring the sealing rolls 14 and 16 close to the strip 3 to thereby suppress flow of the inert gas G from a space 72 to a space 71. <IMAGE>
