Five stages of glass melting

Hello, what are the five stages of glass melting? In the glass melting process, it can be divided into the following five stages:

1, glass raw material batching: At this stage, the glass batching is evenly mixed according to a certain proportion to ensure the accuracy of the glass composition and batching ratio produced in the melting process.

2. Melting of glass raw materials: put the mixed glass raw materials into a glass kiln, heat and melt until the melting point of glass is reached, and form a continuous, uniform, bubble-free and transparent liquid glass melt.

3. Adjusting the glass composition: In the kiln, different glass compositions can be achieved by adding appropriate components (such as increasing the content of SiO2 _ 2 and controlling the content of Na2O) to the glass melt.

4. Modeling: The glass melt can be modeled, and glass products with different shapes, such as glass and glass plates, can be completed by injection molding, extrusion and other processes.

5. Cooling: the glass product is rapidly cooled and quenched, so that it changes from the molten state of glass to the solid state of glass, that is, the forming and cooling process of the product is completed. The above five stages are the main processes in the glass melting process, and each stage has an important influence on the quality and performance of the finished product.
