摘要： PROBLEM TO BE SOLVED: To provide a glass float process which is easy to carry out and can prevent the undesirable devitrifications in the edge regions to an extent such that neither do increased strains appear in a glass ribbon nor is a glass broken in an annealing oven even in the floating of glasses prone to crystallization (namely green glasses for production of glass ceramic plates).
SOLUTION: The process for producing a flat glass comprises pouring a liquid glass being a precursor of glass ceramics into a metal bath which is in an inlet zone and forms the glass into a ribbon having a prescribed width and thickness so that the glass flow in the inlet zone abuts on at least one heating boundary wall, heating at least one heating boundary wall to a temperature equal to or higher than the upper devitrification limit (UDL), and indirectly heating at least one heating boundary wall.

摘要翻译：要解决的问题：提供一种易于实施的玻璃浮法，可以防止边缘区域中不希望的失透，使得玻璃带中不会出现增加的应变，也不会在玻璃带中破裂甚至在玻璃漂浮的退火炉容易结晶（即生产玻璃陶瓷板的绿色玻璃）。解决方案：制造平板玻璃的方法包括将作为玻璃陶瓷的前体的液态玻璃倒入到入口区域的金属浴中，并将玻璃形成具有规定宽度和厚度的带状物，使得玻璃入口区中的流动与至少一个加热边界壁邻接，将至少一个加热边界壁加热到等于或高于上部失透极限（UDL）的温度，并间接加热至少一个加热边界壁。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a glass float process which is easy to carry out and which can prevent the undesirable devitrifications in the edge regions even in the floating of glasses prone to crystallization.
SOLUTION: The process for producing a flat glass prone to crystallization includes a step of pouring a liquid glass in a glass flow form on a metal in an inlet zone on which the liquid glass is formed into a glass ribbon having desired width and thickness to thereby bring the glass flow in the inlet zone into contact with a wetback tile and/or restrictor tile. By forming a liquid film comprising a float bath metal between the wetback and/or restrictor tiles in the inlet zone and the glass flow, the liquid film prevents a direct contact of the liquid glass with the wetback and/or restrictor tiles.
