1. Brief introduction
Glass is a special amorphous inorganic nonmetallic material. The main component is silicate, a non-crystalline solid with an irregular structure.
Glass melting is the most important process in glass production, it is a forming process where the batched materials form a qualified liquid evenly with no bubbles under high temperature heating.
At present, most of the tube glass production line mainly adopts horizontal stretching Danner process and Vello process.
2. Forming process
The glass liquid flows out from the furnace through the throat, goes into the rotating cylinder, the glass liquid will form a tubular type under a rotating speed of the cylinder. The tubular shape will be stretched and form a glass tube via graphite guide roller by Danner machine.
The glass liquid flows out from the throat, and goes into a heat-resistance alloy pipe, the glass liquid will form into a tube under the function of compressed air.
