    Abstract: A casting roll moving apparatus for a twin roll type continuous strip casting process is disclosed. The casting roll moving apparatus is used with a twin roll type strip casting machine that produces a strip through a method in which, while high-temperature steel melt is supplied between twin rolls which rotate in opposite direction, a large amount of heat is dissipated through the rolls by contact between the steel melt and the rolls, so that the steel melt is rapidly solidified. Opposite ends of the rolls are automatically aligned, so that the recovery rate of the apparatus is increased, and a stable casting process is ensured. Because friction of the apparatus is markedly reduced so that an even rolling force is ensured, a gap between the rolls is maintained constant. Thus, the thickness of a cast strip is maintained constant, and the problem of the occurrence of an uneven surface pattern is solved.
