MOLTEN GLASS CONVEYING EQUIPMENT ELEMENT, METHOD FOR MANUFACTURING MOLTEN GLASS CONVEYING EQUIPMENT ELEMENT, GLASS MANUFACTURING APPARATUS COMPRISING MOLTEN GLASS CONVEYING EQUIPMENT ELEMENT AND METHOD FOR MANUFACTURING GLASS PRODUCT

摘要

The present invention provides a molten glass conveying equipment element which has a ceramic structure that achieves prevention of crack generation in a conduit caused by thermal expansion during heating or contraction during cooling as well as prevention of conduit deformation caused by inflation pressure applied by molten glass, and that is not susceptible to erosion even if the molten glass leaks for some reason. The present invention also provides a method for manufacturing the molten glass conveying equipment element and a glass manufacturing apparatus comprising the molten glass conveying equipment element.
