Clear Big Size 380V Tube Glass Production Line Making Machine

Clear Glass Tube, Glass Processing Plant, Big Size Tube Making Process


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.


Physicochemical changes in each glass melting stage:
  • Silicate forming
In this stage, the components of batched materials will produce a physicochemical solid phase reaction during heating process, in which the gaseous products will be released from the batched materials and produce a new opacity sinter ultimately, which is formed by silicate and SiO2.
  • Glass liquid forming
In this stage, the sinter will be melting and the silicate and SiO2 in sinter will change to flint glass liquid with a plenty of bubbles. However, its chemical components and character are not even.
  • Clearing
The glass liquid is continuously heated, and its viscosity is reduced with plenty of gaseous sundries released, which should eliminate the visible bubbles with the pool of liquid.
  • Homogenization
The glass liquid is kept at high temperature for a long time, the ripple eliminates by diffused function and homogenizes as a whole. The temperature of homogenization can be lower than the clearing stage.

2. Forming process


  • Danner 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.


  • Vello process

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.
