A cooling apparatus and related method for a continuous casting apparatus includes a series of spray nozzles for spraying a coolant against one surface of a moving chill substrate. The invention apparatus includes an enclosure having vacuum applied thereto for preventing migration of the sprayed coolant from the surface against which it is sprayed to the surface contacting the molten solidifying material. Any coolant having a tendency to escape along sealed edges of the enclosure is forced back into the enclosure by the pressure gradient. The edges are sealed by elongated plastic rods. Additionally, scrapers are provided for removing remanent coolant from the sprayed surface. The coolant is sprayed at a high velocity to increase its heat transferring efficiency.

Method and apparatus for cooling a moving chill substrate

A casting assembly has a casting nozzle for dispensing a melt puddle upon a casting surface of a continuously moving chilled substrate. A vibratory support contacts the chilled substrate opposite the casting nozzle and includes an ultrasonic transducer for exciting the substrate. The support applies ultrasonic vibrations through the substrate to the melt puddle prior to the critical period of solidification for enhancing wetting of the substrate and improving heat transfer between the melt puddle and the chilled substrate.

Heat transfer during casting between metallic alloys and a relatively

This invention relates to the production of large non-planar shapes of metallic glass fabricated from ribbon. The inventive method contemplates stacking the ribbon. The stacked ribbon is formed and held at temperatures of between 70 and 90% of the crystallization temperature for a time sufficient to facilitate permanent deformation of the stacked ribbons and to bond the ribbons.

Amorphous press formed sections

This invention relates to the production of large shapes of metallic glass fabricated from ribbon. The inventive method contemplates placing the ribbon and consolidating the alloy under a pressure or at least 1000 psi at a temperature of between 70% and 90% of the crystallization temperature for a time sufficient to facilitate bonding of the ribbons.
