Abstract

1332549 Continuous casting CONCAST AG 19 April 1971 [10 March 1970] 22993/71 Heading B3F Cooled plate-walls of an arcuate, vertical or inclined mould are supported in a surrounding frame 5, at least one of the side walls (2<SP>1</SP>) being movable, as by a piston-and-cylinder unit (6), to grip the end walls 3 between the side walls; the end walls are slidable in or out of the mould top, being supported in the mould by hook-shaped elements and held by drawn-in keys or magnetic clamps or, as shown, by T-blocks 13 on the frame 5 loaded by springs 15 to clamp guideways 8 backing the end walls 3 and each having a T- sectioned slot 12 slidable over a block 13, there being means such as spindles 16 operable from the top of the mould for releasing the clamps at each end. Raising of a screw spindle 16 in the frame 5 brings enlargements 17 to bear on studs 11 attached to a slide block 13 to compress springs 15 and release the guideway of an end wall 3 which may then be removed when worn or for replacement, e.g. by a wall 18 of different width and/or thickness to change the cavity breadth or width, or by a wall which changes the cavity taper. Each end wall consists of a copper plate 7 on a backing plate 8 and coolant water connections to the wall are made by the placement of the wall. Like the side wall 2, one of the end walls 3 may be fixed. There is also described a mould in which the end walls are secured as before but are each shiftable by two screw spindles (34) for adjusting the cavity size. A holder (42) for the end wall is secured to a yoke (41) slidable at its ends on the frame 5 and conveying water to the end wall, or the yoke is attached directly to the wall.
