What are the advantages of a two heating chamber glass tempering furnace?

Two heating chamber glass tempering furnace mainly consists of:

Loading table

Preheating oven

Heating oven

Quenching section

Unloading table

Control system

Blower system

The temperature of the preheating section (low temperature section) is generally between 450-500 degrees, and the temperature of the high temperature section (heating section) is generally around 700 degrees. This glass tempering furnace is mainly used for processing LOW-E glass and high grade glass.

The radiation heat transfer efficiency of glass is relatively low in the low temperature range, and LOW-E glass has a strong reflection to radiation heat, which means that the efficiency of using radiation heating in the low temperature range will be lower. However, adopting forced convection heating system can solve this problem, greatly improving heat transfer efficiency and effectively shortening heating time;

The furnace temperature in the high temperature section is relatively high, and the effect of radiation heat transfer is obvious. However, the reflection of radiation heat by LOW-E glass can not be ignored. In order to further improve the uniformity and effectiveness of high-temperature heating for ordinary glass, it is still recommended to use forced convection heating system in the high temperature section, so as to strengthen the equipment configuration and significantly improve the quality of tempered glass.

The double chamber glass tempering furnace can shorten the heating time. The main problem that occurs when glass is heated for a long time in the furnace is that the possibility of scratches on the lower surface of the glass increases, and the waviness of the glass also tends to increase. At the same time, the surface quality and optical properties are affected, so the quality of tempered glass will decrease. The two heating chamber glass tempering furnace can effectively solve this problem, greatly reducing the probability of defects in the glass during the heating process. By increasing production, the quality of tempered glass can be greatly improved.
