The causes and preventive measures of self explosion of tempered glass furnace

Self explosion of tempered  glass furnace refers to the phenomenon of sudden glass bursting during the tempering furnace processing. This situation may lead to serious personal injury and equipment damage. Therefore, it is important to understand the causes and preventive measures of self explosion. Here, we will briefly introduce:

1. The reasons for self explosion of tempered glass furnace

1.1. Defects on the glass surface

During the glass production process, if there are any defects or damages, such as scratches, collisions, damage, or thermal stress, the glass surface may produce areas of concentrated tension. These areas may experience stress concentration during the heating process, leading to glass self explosion.

1.2. Uneven temperature

Uneven heating temperature in the tempering furnace can also lead to glass self explosion. If the surface temperature of the glass is too high and the internal temperature is too low, the tension generated on the surface and inside is inconsistent, leading to glass self explosion.

1.3. Improper operation during the processing

During the operation of the tempering furnace, improper processing, such as bending or twisting glass, can also lead to glass self explosion.

1.4. Equipment aging

Long term use of tempering furnaces, equipment aging and wear can also lead to glass self explosion. For example, aging of heating elements can cause temperature instability, leading to glass self explosion.

2. Preventive measures for self explosion of tempered furnace glass

2.1. Optimize production process

During the production process, it is advisable to avoid introducing any defects or damage to the glass surface as much as possible. In addition, when heating in a tempering furnace, the temperature should be controlled to ensure that the temperature on the surface and inside of the glass is as uniform as possible.

2.2. Improve operational skills

For operators of tempering furnaces, their operational skills and awareness should be improved. Operators should follow the correct operating procedures to avoid twisting or bending the glass during the processing, in order to reduce the accumulation of stress.

2.3. Regular maintenance of equipment

The tempering furnace should be regularly inspected and maintained to ensure the stability and reliability of its equipment. The aging of heating elements and control systems should be replaced in a timely manner to avoid glass self explosion caused by equipment aging.

2.4. Strengthen quality inspection

During the production process, regular quality inspections should be conducted on glass, as well as inspections of tempered glass. Defective glass should be promptly eliminated and recorded to analyze the cause and prevent similar situations from occurring.

In summary, the self explosion of tempered furnace glass is caused by various factors, so multiple preventive measures need to be taken during the production process. By optimizing production processes, improving operational skills, regularly inspecting equipment, and strengthening quality inspections, the risk of glass self explosion can be reduced, ensuring the safety of production and employees.
