With a total of seven patents to his name, Williams has developed innovative methods and devices that enhance the production of metal strips, showcasing a blend of creativity and technical expertise.

Latest Patents

Among his latest patents is the "Method of continuously casting electrical steel strip with controlled spray cooling." This inventive method enables the continuous casting of grain-oriented electrical steel by utilizing a controlled rapid cooling step, such as a water spray. This approach not only ensures the appropriate grain orientation of the finished product but also enhances its physical properties, reducing instances of cracking. The process involves initial secondary cooling of the cast strip to temperatures between 1150 and 1250 °C, followed by rapid cooling at a rate of 65 °C to 150 °C per second, effectively bringing the temperature down to no greater than 950 °C.

Another notable invention by Williams is the "Segmented roll for casting metal strip." This patented design features a segmented roll system for casting molten metal into a continuous strip. It includes a tundish for containing the melt and horizontally disposed, water-cooled composite casting rolls. Each casting roll is composed of multiple annular segments, which are equipped with coolant openings and alignment features to maintain structural integrity. The innovative design facilitates efficient metal casting while optimizing cooling processes through flexible conduits for coolant water supply and removal.
