Abstract: 686,322. Casting-machines. SANKEY & SONS, Ltd., J. March 7, 1951 [March 15, 1950], No. 6495/50. Class 83 (i)] A mould for continuous casting comprises four posts supporting vertically aligned side and end members defining a central rectangular mould. The members being spaced apart vertically to allow free expansion thereof and preferably having means for feeding lubricant into the spaces between the members to prevent the escape of metal. The four corner posts 11 are slotted to receive lugs 13a, Fig. 4, extending laterally from the upper end of side plates 13 and lugs 14a extending from end plates 14 which have vertical tongues 14b projecting between the side plates. Plates 13 are hollow and intended to be liquid cooled. As seen in Fig. 3, small expansion gaps 35 are left between the posts and the members 13, these gaps being covered by the said tongues 14b. Members 13 are held against outward movement by anchor plates 16 which are bolted to the posts 11 at 17 and overlap two adjacent members. Opposed plates 16 are also drawn together by bolts 20 and springs 21, Fig. 2. Similar plates 18 are bolted at 19 across the ends of the assembly. Each of the plates 16, 18 has a slot 23 or 25 aligned with the gaps between the adjacent side members 13 and end members 14 respectively and integral with a hopper and feed channel. The passage of the casting through the mould is facilitated and the escape of metal from the gaps between the members is prevented by lubricant which is fed into the gaps from the hoppers by means of plungers pressed forward by weights. Any suitable form of lubricant may be used. As shown, finely comminuted lubricant is fed through the side ports 23 and a lubricant in block form, such as graphite, through the end ports 25. The ports 23 are shorter than the full width of the plates 13, the ends of the gaps being filled by corner guides 30. Specifications 686,413 and 697,788 are referred to.
