Title: Nelson H. Kehl: Innovator in Molten Metal Stirring Technology

Introduction

Nelson H. Kehl is a notable inventor based in Hinsdale, IL (US). He has made significant contributions to the field of molten metal stirring technology. His innovative approach has led to the development of a unique patent that enhances the efficiency of stirring molten metals.

Latest Patents

Kehl holds a patent for a "Lance for stirring molten metal and method of making the same." This invention involves a steel tubular member that is coated interiorly with wax. A refractory material plug is cast within the member, extending from one end while leaving a clear space near the other end. Melting the wax creates a thin gas passageway around the plug. The capped end is connected to a gas feed pipe, which is surrounded by a stiffener member covered with a refractory material protective sheath. The refractory material in the tubular member erodes slightly during each use, ensuring that the gas discharge gap remains clear. This innovative design allows for more effective stirring of molten metals.
