Abstract

800,981. Continuous - casting machines. BABCOCK & WILCOX CO. June 21, 1956 [July 19, 1955], Class 83 (1). An upright open-ended fluid-cooled casting- mould comprises horizontally-spaced side-wall sections and associated end-wall sections including mould liner members, vertical edges of at least two of such liner-members abutting faces of adjoining liner-members, and each of the liner-members being supported and guided by separate structural support-plates serving also to define a coolant passageway along the exterior surface of said liner-members. The mould is formed of four sections A-D, Fig. 3. Each side-wall section A, C, comprises a sheetmetal liner 10, Fig. 1, which is supported by a brass skirt-plate 11 which extends to a position 12 intermediate the length of the liner. The liner is supported on the plate 11 by a series of longitudinally-extending keys 24, Fig. 5, which allow longitudinal and transverse thermal movements of the line, and so dimensioned as to leave coolant-passages 33, into which coolant flows from an inlet-chamber 14. The plate 11 is backed by a reinforcing-plate 13 which is supported by a bracket 38 on a surface 39, so that the side-wall may be adjusted for various sizes of ingots. Each end-wall B, D comprises a hollow member 40, Figs. 2 and 6, and a plate-member 56 which defines coolant passages 57 over part of the length of the member 40. The member 40 and plate 56 are bolted to a weir-plate 61, which is in turn secured to a structural member 62. When assembling the mould for the desired cross-sectional dimensions, the edges of the end-walls B, D, are coated with an initially plastic sealing material such as a mixture of graphite and cooked starch.
