Introduction
Curtis J McMinn is a notable inventor based in Florence, Alabama, recognized for his contributions to the field of aluminum reduction technology. With a total of four patents to his name, McMinn has made significant advancements that enhance the efficiency and effectiveness of aluminum production processes.
Latest Patents
One of McMinn's latest patents is the "Aluminum reduction cell carbon anode power connector." This invention discloses an electrical connector designed for use in an aluminum reduction cell. The connector's portion that extends into the carbon anode block is made from a steel alloy containing at least 0.8% by weight chromium, which exhibits electrical resistivity characteristics similar to mild steel at the operating temperatures of the block.
Another significant patent is for "Cathodes for alumina reduction cells." This invention focuses on drained cathodes that provide a refractory surface for contacting molten aluminum on the cell floor. The cathodes consist of a carbonaceous bed, preferably a graphite bed, and a composite tile. The tile features a layer of refractory hard metal (RHM) material bonded to a base layer of graphitic material. The RHM layer is created by hot pressing a mixture of titanium diboride and aluminum nitride powders directly against the graphitic base layer, ensuring a strong bond. This innovative design enhances the performance of alumina reduction cells.
