Abstract

The invention discloses a novel process of a flat glass substep combined molding floating method. The novel process is characterized in that by taking a low-melting point liquid tin tank as final floating method molding equipment of flat glass, a molding mode of the flat glass is divided into a two-step molding method and a three-step molding method, primary molding of the two-step molding method is implemented by using a lead-up flat drawing molding method or a high-melting point liquid metal tank floating method, and a high-temperature plastic glass strip is manufactured firstly, and is further led into the low-melting point liquid tin tank to be finally molded; primary molding of the three-step molding method is implemented by using the lead-up flat drawing molding method, middle molding is implemented by using the high-melting point liquid metal tank floating method, the high-temperature plastic glass strip is manufactured firstly, and is further led into the liquid tin tank to be finally molded. According to the novel process of the flat glass substep combined molding floating method, the high-temperature plastic glass strip of which the width is equal to that of a liquid tin surface or is approximate to that of the liquid tin surface and is uniform in thickness is led into the liquid tin tank, instead of molten glass which spreads and is flattened through self weight thereof in a conventional floating process.
一种平板玻璃分步联合成型浮法新工艺,其特征是:将低熔点液态锡槽作为平板玻璃的最终浮法成型设备,将平板玻璃的成型方式分为二步成型法或三步成型法,其中二步成型法的初步成型采用引上平拉成型法或高熔点液态金属槽浮法,首先制造出高温塑性玻璃带,再将其引入到低熔点液态锡槽中最终成型;而三步成型法的初步成型采用引上平拉成型法,中步成型采用高熔点液态金属槽浮法,首先制造高温塑性玻璃带,再将其引入到液态锡槽中最终成型;在这种平板玻璃分步联合成型浮法新工艺中,被引入液态锡槽的是与其锡液面宽度等宽或接近等宽且厚度均匀的高温塑性玻璃带,而非传统浮法工艺中有待依赖其自重和粘度摊开、摊平的玻璃液。
