How to set the heating time of the glass tempering furnace？

Glass tempering furnace is a common glass heat treatment equipment, which is essential for many glass processing plants.

The quality of tempered glass depends on many factors, especially how to set the correct processing parameters.

Heating time is a very important parameter among these, and it plays a crucial role in the quality of tempered glass.

In the actual operation process, operators need to adjust the heating time based on factors such as glass thickness, the area of a single piece of glass, and the number of pieces placed in a single load to ensure the stability and consistency of the tempering effect.

In addition, it is necessary to pay attention to the balance between heating temperature and heating time during the heating process to avoid excessive or insufficient heating, which may cause problems with the glass.

In summary, for the operator of the tempering furnace, setting the heating time reasonably is the key to ensuring the quality of tempered glass.

PS: Heating time refers to the residence time inside the glass heating furnace

Taking the radiation glass tempering furnace as an example:

For normal clear float glass:

The heating time is about 40-50 seconds per millimeter

For example, the heating time for 6mm clear float glass is: 6x40 seconds=240 seconds

Attention:

The heating time setting for glass may vary depending on the actual situation: such as, If the area of a single piece of glass is different and the number of pieces placed in a single load is different, it will have a significant impact on the heating time. Therefore, appropriate adjustments need to be made according to the actual situation during operation.

The heating time of glass tempering furnace with forced convection system is shorter than that of normal radiation glass tempering furnace

And the force convection type glass tempering furnace is very suitable for processing Low-e glass, especially the soft Low-e glass (off-line Low-e glass), so now, for most market, force convection type glass tempering furnace is more and more popular. But the cost of this type glass tempering furnace is also higher than normal radiation glass tempering furnace.
