  • System and method of forming a solid casting
    Patent number: 9434000
    Abstract: A method and a system for forming a solid casting. A material is fed into a mold having a retractable bottom. A first portion of the material at a first, lower position within the mold is allowed to solidify to thereby form a portion of the casting. The retractable bottom is withdrawn downwards at a withdrawal rate. A second portion of the material at a second, upper position within the mold is maintained in a liquid state by application of heat thereto, using a plasma arc generated by a plasma arc torch. A voltage of the plasma arc is measured, and the withdrawal rate of the retractable bottom is controlled based on the voltage of the plasma arc.
