<p>1,197,191. Continuous casting. A. WERTLI. 25 Oct., 1967 [26 Oct., 1966], No. 48557/67. Heading B3F. Cooling water flows at high speed (2-20 m.sec) in a film through a narrow gap 13 (0À5- 1 mm.) between surfaces 8, 10 of a cooling jacket 2, 9 at each broad side of a horizontal mould 1 permanently fixed to a furnace containing a melt, for continuously casting a metal strip 4. The strip is withdrawn continuously or intermittently in the direction of the arrow 5. The water passes from an inlet 11 and chamber 14 through to a collecting chamber 15 of diverging form to enhance cooling at the mould inlet. The upper and lower cooling jackets are identical, each comprising a cover 9 in a recess 7 in a part 2, and they are held together, on the broad sides of the mould 1 by screws (6) passing through their overhangs at the mould sides. There may be several recesses 7 side-by-side, extending along the mould, each with its own cover 9, to create several gaps 13 with differing quantities of water in them. The graphite mould 1 may consist of two parts, an upper and a lower, or of four parts, each of the narrow edge surfaces being formed by a separate part.</p> |
