Abstract
Cut-out portions or horizontal passages in the form of an inverted T are provided to melt solidified shells grown at triple points at which side seal plates, colling rolls and molten metal are made contact with each other. Pouring holes or slits are provided for inside pouring. Length of the slit in the cast widthwise direction is preliminarily determined so as to maintain temperature distribution in molten bath uniformly. Start of a continuous casting operation is facilitated by movable baffer plates disposed at open ends of the horizontal passage.
Claims9
In a dual roll type continuous casting machine having cooling rolls disposed in parallel with each other, side seal plates disposed at opposite end faces of said cooling rolls to define together with said cooling rolls a molten bath and a core inserted and supported within said molten bath, an improvement comprising inside pouring passage means formed through said core for supplying a molten metal vertically into a gap between said cooling rolls and side pouring holes formed through longitudinally opposite ends of said core to open in opposed relationship with said side seal plates, each of said side pouring holes terminating in a cut-out portion to define together with the corresponding side seal plate a molten metal passage.
