1322191 Continuous casting VEREINIGTE OSTERREICHISCHE EISEN-UND STAHLWERKE AG 26 May 1970 [30 May 1969] 25287/70 Heading B3F A mould 1 for vertically casting continuous slabs is releasably connected, e.g. by bolt-andwedge fastenings 3-6, in a reciprocated watercooled frame 2 having vertical guide bars 37, 38 mounted at opposite ends, guided by rollers 41-50 mounted on a pouring platform (53) and adjustable to obtain play-free engagement with the guide bar at each end of the frame and maintain vertical guiding of the bars. The frame 2 is mounted (between the guides 37, 38 and mould 1) on rocking levers (19, 20) to reciprocate the frame 2 and mould. Guiding rollers 41-48 are arranged two at each side of a guide 37 or 38, one above the other. Lateral forces are absorbed by further rollers 49, 50 each contacting the outer side of a guide. The rollers are mounted in sheet metal housings connected to the pouring platform. Cooling water supplied to the frame 2 through ducts 7-10 flows from outlets 11, 12. There are spigot-and-bushing connections 13-16 between the fame 2 and mould 1 for flow to the mould and similar connections 17, 18 for the outflow to 11 and 12. Expansion differences are thus avoided. The frame is mounted on levers (19), 20 which rock about pivots 21, being driven by an adjustable rod 34 reciprocated by an eccentric 35 which rocks a spindle 31 about a shaft 29. The pivots 21 are on pivoted crank levers 24 having a spring anchorage 26. To lower the mould and minimize the stroke of the frame 2 and mould 1, a motor 32 rotates a spindle 31 so that a nut 31<SP>1</SP> bearing the top of the rod 34 travels along the spindle and moves the rod to position 34<SP>1</SP>.
