Melting Capacity 60TPD Industry Melting Furnace Construction Service
1. Brief Description
Glass is a special amorphous inorganic nonmetallic material. The main component is silicate, a non-crystalline solid with an irregular structure.
Glass furnace is a melting device, which is the most necessary and important equipment for the glass industry.
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.
Physicochemical changes in each glass melting stage:
1.1 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.
1.2. 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.
1.3. 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.
1.4. 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. Type of Furnace
2.1. Capacity
| Item | Description |
| Small scale furnace | Daily furnace capacity: below 50tons |
| Medium scale furnace | Daily furnace capacity: 50tons~150tons |
| Large scale furnace | Daily furnace capacity: 150tons plus |
2.2. Heating source
| Item | Description |
| Fired furnace | The combustion fuel can be natural gas, heavy oil, diesel oil…… for this kind of furnace. |
| Electric furnace | Electricity is the fuel for this kind of furnace. |
| Fired-electric furnace | This kind of furnace is mainly using combustion fuel, electricity is used as a supplementary heating source. |
3. Furnace melting technology system
The temperature must be strictly controlled, it affects the glass melting speed, glass liquid convection situation, glass forming condition, fuel combustion, furnace campaign, etc.
