With a total of 2 patents to his name, his work has advanced the understanding and efficiency of metal processing.

Latest Patents

One of Sergei's latest patents is a "Method of gas-dynamic stirring of liquid molten metals and apparatus for." This invention involves a unique process where, directly prior to the supplying of the expelling pulse of compressed gas into the pump tube, the suction supply is cut off. This allows the withdrawn portion of metal to be expelled into the molten metal body under the action of its own weight and the compressed-gas pulse. To ensure precise timing of the suction cut-off moment and the gas pulse supply, the pump cover is equipped with rod valves that cooperate with a floating sleeve actuated by the molten metal. Additionally, at least one electric contact probe is wired into the circuit controlling the supply of compressed gas pulses.

Another significant patent is the "Method and apparatus for stirring molten metal." In this process, a portion of molten metal is alternately withdrawn from beneath the surface and expelled into the lower part of a metal holding means through a gas-dynamic pump. The pump pipe is designed for axial reciprocation and angular swinging, enabling effective stirring of the melt body throughout the bottom area. The stepwise reciprocation of the pump pipe is achieved through a pneumatic positioning device, with the frequency of the metal-withdrawing and expelling cycles alternated by a preset time relay.
