Introduction

Charles J Petry is a notable inventor based in Colchester, Vermont, who has made significant contributions to the field of metal casting technology. With a total of 2 patents, his work focuses on improving the processes involved in feeding and continuously casting molten metal.

Latest Patents

Petry's latest patents include a method and apparatus for feeding and continuously casting molten metal. These innovations describe a process where inert gas is applied to the moving mold surfaces and the entering metal. This application serves to protect the molten metal surface within the mold cavity from oxygen and other harmful atmospheric gases. The shrouding of the molten metal is achieved through inert gas injected into the mold via a semi-sealing nosepiece or directed at the mold cavity, ensuring that the metal remains uncontaminated. The inert gas is circulated to cleanse the mold surfaces of undesired gases, such as atmospheric oxygen and water vapor, as they approach the mold region. The design also emphasizes a noiseless ejection of gas to avoid air entrainment, utilizing both heavier-than-air and lighter-than-air inert gases strategically.
