<p>The object of the invention is to provide a continuous metal casting machine in which dimensional changes of the mold during the casting operation are measured and regulated to achieve a desired result in the cast metal. The continuous casting machine includes a copper tubular or plate mold (22) into which molten metal (25) is poured for forming a strand (25b) of high melting point metal, such as steel. A plurality of spray nozzles (29) are spaced around the mold for directing sprays (30) of coolant fluid against the mold. In accordance with the invention, one or more measuring devices (32) are associated with the mold for measuring changes in dimension of the mold in a direction transverse to the longitudinal axis thereof, and controls (36) are connected with the coolant fluid to adjust the rate of heat extraction effected thereby to thus regulate the extent of dimensional change in the mold as molten metal is being cast therein. The method of monitoring and adjusting the extent of dimensional change in a mold of a continuous casting machine as molten metal is being cast therein is also disclosed.</p> |
