1,058,044. Continuous casting machines. KOPPERS CO. Inc. March 24, 1965 [March 26, 1964], No. 12581/65. Heading B3F. In a continuous casting machine means provided to guide and cool the cast slab 15, Fig. 1 (not shown), as it leaves the mould comprises two roller aprons 23 and 33 located one below the other and beneath the mould 17. Each apron is formed in two sections 24, 26 and 32, 34 respectively the sections being positioned one on each side of the cast slab 15. Roller apron 23 includes guide rolls 31 which contact the surface of the slab and are cooled by water spray. The sections 32 and 34 of the roller apron 33 are in the form of recirculatory endless chains of rollers 37 which are water cooled and supported on tracks 39. The movement of the cast slab imparts movement to the roller chains and rotation of the rollers due to friction contact between the slab and rollers. The speed of movement of the slab is controlled by the withdrawal rollers 21. Alternatively, the roller chains may be power driven so as to effect withdrawal of the slab as well as supporting it in which case withdrawal rollers are not required. In order to accommodate cast slabs of different thickness one of each pair of apron sections is adjustable, by hydraulic means, transversely to the passage of the slab 15. Bending and straightening rolls may be provided below the guide roller aprons to direct the strand into a horizontal path.
