Title: William M Marrison: Innovator in Thin Gauge Roll Casting
Introduction
William M Marrison is a notable inventor based in McKenzie, TN (US). He has made significant contributions to the field of metal casting, particularly through his innovative methods for producing thin gauge sheet metal. With a total of 2 patents, Marrison's work exemplifies the intersection of engineering and manufacturing efficiency.
Latest Patents
Marrison's latest patent is the "Thin Gauge Roll Casting Method." This method involves the operation of a twin roll casting apparatus designed to produce thin gauge sheet metal at high production rates. The process includes the simultaneous adjustment of various operating parameters, such as roll speed, tip position, roll gap, molten metal input temperature, and exit strip tension. In an iterative fashion, the strip gauge is reduced in steps while increasing the speed of the rolls and pulling the tip back out of the roll bite. Additionally, the temperature of the molten metal input to the feed tip is gradually reduced to ensure proper solidification at higher speeds. A set of pinch rolls closes on the exit strip at a certain gauge thickness to apply a drag to the strip, ensuring proper coil wind-up tension.
