Glass is transformed into tempered glass through heating and processing in a tempering furnace. The primary method of heating is full electrical radiant heating, although a drawback is the potential for heat waste. However, heat waste can be reduced through various methods.

1. Utilizing multi-position heating technology within the glass steel tempering furnace.

Utilizing multi-position heating technology not only yields significant energy savings but also greatly reduces the occurrence of glass tempering furnace explosions. A glass tempering furnace's position refers to the same-sized glass panels moving back and forth within designated areas along the furnace's length, completing a preset time in each area. After the glass reaches the required heating, it moves to the next position.

Although the manufacturing processes and structures of various tempering furnace models differ, the temperatures required for glass heating and cooling are quite similar. For multi-station tempering furnaces, they can significantly reduce temperature differences within the automotive glass tempering furnace, prevent glass from cracking inside the furnace, minimize heat loss, and greatly promote energy conservation and emission reduction.

2. Employing variable frequency technology.

The variable frequency technology in the tempering furnace is commonly used in fan blowing and ceramic roller conveyance, offering significant energy-saving effects. Blowers equipped with variable frequency technology can quickly meet the requirements for air volume in the cooling zone during the glass tempering process, while also generating sufficient wind pressure. This rapid cooling with automatic pressure and air volume regulation greatly saves electricity and reduces energy loss. The optimized matching of fan air volume, wind pressure, and ceramic roller speed also enhances the quality of glass tempering.
