METHOD FOR MINIMIZING EROSION OF REFRACTORY METAL VESSELS IN A GLASS MAKING SYSTEM
摘要
<p>A method of reducing metal loss from the refractory metal of a stirring apparatus for stirring molten glass, and the apparatus therefore are disclosed. The method includes stirring a molten glass with a stirrer comprising a layer containing at least about 50% iridium. An apparatus comprising an iridium-containing layer is also presented. The apparatus may have surfaces adapted to reduce a flow of molten glass over the surface, thereby forming a layer of stagnant, or quasi-stagnant glass on the surface of the stirrer. Adaptations may include grooves in a surface of the stirrer impeller blades, or holes through the stirrer impeller blades.</p>
