Embodiment

[0017] Such as figure 1 Shown, a kind of glass fusion manufacturing process is characterized in that, described process step is:

[0018] (1) Evenly coat the inner wall of the mold with diaphragm paint to complete the diaphragm treatment;

[0019] (2) glass workpiece is packed in the mold in step (1);

[0020] (3) the mold that described glass workpiece is housed is placed on the transmission mesh belt that advances at a constant speed;

[0021] (4) The transmission mesh belt sends the mold equipped with the glass workpiece into the preheating zone, the heating temperature is 10°C-500°C, and the mold and the glass workpiece in the mold are evenly heated by adopting a uniform heating method from top to bottom;

[0022] (5) The transmission mesh belt sends the mold processed in step (4) and the glass workpiece in the mold to the high-temperature heating zone. The heating temperature is 500°C-1713°C, and the method of uniform heating up and down is adopted until the glass workp...

Abstract

The invention provides a manufacturing process of glass melting. The process comprises the following steps: firstly, coating diaphragms on moulds, and then continuously carrying out the processes of pre-heating, high-temperature heating, main cooling, auxiliary cooling, unloading and the like on the moulds equipped with glass workpieces in sequence to manufacture glass plates and other profiles. By adoption of the manufacturing process, glass is molten and molded completely, the produced glass workpieces have no bubbles or less bubbles, no scars, no watermarks, good uniform consistency, difficulty in breaking and high cost ratios, the molten glass is not bonded with the moulds, and the moulds are durable in use, so that the production cost can be greatly reduced, and qualified large-sized glass workpieces can be produced.

Description

technical field [0001] The invention belongs to the field of glass manufacturing, in particular to a glass melting manufacturing process. Background technique [0002] At present, the continuous degree of glass manufacturing process is low, resulting in a high rate of glass breakage, and it is impossible to ensure the integrity of glass fusion and other product quality. Specifically, the temperature change control during the glass shaping process is insufficient, especially the precision of glass heating and cooling cannot be guaranteed, and it is not convenient to adjust the process parameters, resulting in the impact of various indicators of the glass shaping process and product quality. Therefore, there is an urgent need for a glass fusion manufacturing process with high product quality. Contents of the invention [0003] The invention proposes a glass fusion manufacturing process, which solves the problems in the prior art of low process continuity, high glass breakag...
