Abstract
570,953. Moulds. SULZER FRERES SOC. ANON. Dec. 18, 1942, No. 17983. Convention date, Dec. 20, 1941. [Class 83 (i)] A sand mould for casting steel billets is formed internally with convex surfaces 8 so that the solidifying billet has, at first, a crust in the form of arches 18 which does not crack by reason of the pressure of the internal liquid 5 and the contraction, due to sintering, of the sand 2. The sand opposite the points 7 of the casting is not heated thereby to above its sintering temperature and therefore does not yield to radial pressure at these points. The surfaces 8 may run circumferentially, spirally, or radially instead of longitudinally, as shown.
