High Capacity Glass Melting Furnace with Stable Temperature Control for Raw Material Melting Processes

High Capacity Glass Melting Furnace with Stable Temperature Control for Raw Material Melting Processes

1. Brief Description

Glass melting furnace refers to the thermal equipment used in glass manufacturing to melt glass mixtures. Mix the powder prepared according to the glass composition and the added clinker (broken glass) at high temperature in the kiln to melt, clarify, and form a glass liquid that meets the forming requirements. Glass manufacturing has a history of 5000 years, and the manufacturing method of using firewood as fuel and melting glass materials in clay jars has continued for a long time. In 1867, the Siemens brothers in Germany built a continuous coal-fired tank furnace. After 1945, glass melting furnaces developed rapidly.

2. Melting process stages:

The melting process is divided into five stages as following, each section has its inner connection, affecting each other. If one stage has imperfect performance, it will influence the next stage, and ultimately affect the quality of glass.

         Silicate forming

The mixture is converted into a sintered material composed of silicates and silica.

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.

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.

         Cooling

Adjust the viscosity to be suitable for forming.

 3. Furnace melting technology system

Furnace melting technology includes temperature, pressure, bubbling, glass liquid level, fuel, reversing system etc.
