| description | PROBLEM TO BE SOLVED: To provide a molding method of plate glass that improves wavy deformation of a glass ribbon.SOLUTION: A molding method of plate glass includes a step for suppressing shrinkage in the width direction of a belt-like glass ribbon G. A support roll 40 is installed to support the glass ribbon G in a viscosity range A of 10dPa s-10dPa s. The support roll 40 has at the tip a rotary member 50 that contacts the glass ribbon G, the rotary member 50 being made of ceramic without a refrigerant flow passage therein. At least part of the rotary member 50 that contacts the glass ribbon is made of sintered silicon nitride ceramic containing 0.1 mass% or less of Al, 0.7 mass% or less of Mg, 0.9 mass% or less of Ti, 3.5 mass% or less of Zr, and 0.5-10 mass% of Y.SELECTED DRAWING: Figure 1
【課題】ガラスリボンの波状の変形が改善された板ガラスの成形方法を提供する。【解決手段】帯板状のガラスリボンＧの幅方向の収縮を抑制する工程を有する板ガラスの成形方法であって、前記ガラスリボンが１０６．７ｄＰａ・ｓ〜１０７．６５ｄＰａ・ｓの粘度範囲の領域Ａで前記ガラスリボンＧを支持する支持ロール４０が設けられ、該支持ロール４０は、前記ガラスリボンＧと接触する回転部材５０を先端部に有し、該回転部材５０が、内部に冷媒流路を有しておらず、セラミックスで形成されている。前記回転部材５０のうち少なくともガラスリボンと接触する部分が窒化ケイ素質セラミックスであり、Ａｌ：０．１質量％以下，Ｍｇ：０．７質量％以下，Ｔｉ：０．９質量％以下であり、Ｚｒ：３．５質量％以下、Ｙ：０．５〜１０質量％含有する焼結体の窒化ケイ素質セラミックスである。【選択図】図１ |
