Abstract

1392472 Continuous casting SCHLOEMANN AG 14 July 1972 [17 July 1971] 33179/72 Heading B3F A mould 7 and a number of guide segments 19/20 of an arcuate guide apron are attached to a supporting frame 1 which is disposed at the inside of the arc and supported by basic structure of the plant at two bearing points, viz. at a main bearing 2 (such as a horizontal pin or, as shown, surface resting on a girder 3 to which the frame 1 is attached by a screw 4) vertically aligned with the centre of gravity of the assembly, and at a loose bearing 5 affording the assembly freedom of movement parallel with the longitudinal axis of the guide path 52 of the apron; the segments 19/20 are movable out of alignment with the apron in a direction away from the frame and a straightening and withdrawing machine 60 follows the apron. Each guide segment comprises an inner part 19 and an outer part 20 both slidable on columns 18 for relative adjustment by a cylinder 24 attached to the frame 1 and for transfer by the cylinder 24, when a stop 22 is removed, to a segment-changing carriage 27 which may serve a number of aprons of a multistrand installation. For insertion or removal of a dummy bar 36 into or from the casting machine, the outer part 20 of at least one guide segment is separately displaceable, to a position 35, by cylinders 30, 31 so that a magazine 40 for the bar 36, and contained in a casing 37, can be introduced into the opening so created. The mould 7 is suspended in a cradle having sideplates 8 attached to the frame 7 by links 9 and levers 10, each of the latter being oscillated by a cylinder 12. Suspended from a bracket 14 on the frame 1 the sideplates 8 is an initial guiding and cooling section 13. It has rollers 15 held between guide rails 16 on the inside of the sideplates 8.
