Abstract:
1. A continuous casting mold coolant wiper control process comprising the following: providing a continuous casting mold with a mold cavity configured to cast a castpart; providing a castpart wiper configured to conform around an outer surface of the castpart and thereby direct flow of coolant away from the outer surface of the castpart; positioning the castpart wiper at an initial startup position sufficiently below the castpart starting block to avoid mis-directing coolant during a startup phase of casting; initiating casting and providing coolant to the casting mold; rapidly moving the castpart wiper from the initial startup position to a position immediately at or near the mold cavity and above the position at which a core of the castpart becomes solid during a transition heat-up phase of casting; and then moving the castpart wiper away from the mold cavity during a second transitory stage of the casting at a rate determined to result in a predetermined castpart solidification effect and below a position at which the core of the castpart becomes solid.
