ABSTRACT:
An apparatus and method for cleaning the precipitate from the outside of a mold tube in a metal casting machine, includes spray nozzles positioned around the mold tube for spraying a chemical solution against the tube, in situ, to dissolve precipitate thereon, thus avoiding the necessity of removing the mold tube from the machine or otherwise shutting down the casting operation. In spray cooled machines, the water used to cool the mold tube can be used to rinse away the solution and dissolved precipitate.
