What should we do when power shut down power off for glass tempering furnace and its hazards?

With the continuous development of the glass industry, glass tempering furnaces, as one of the key equipment, play an important role in glass processing. However, a sudden power outage in the glass tempering furnace may bring a series of hazards, and urgent measures need to be taken to ensure the safety and effectiveness of the production process.

1. The hazards of sudden power outage in glass tempering furnaces

1.1. Glass loss

The sudden power outage caused the glass to cool too quickly, resulting in a sharp increase in temperature difference and a stress difference between the surface and interior of the partially heated glass. This temperature difference shock may cause cracks inside the glass, and in severe cases, even lead to the shattering of tempered glass. This situation will lead to glass loss, not only increasing production costs, but also wasting raw material resources, which will have an impact on the economic benefits and production efficiency of the enterprise.

1.2. Equipment damage

A sudden power outage in the glass tempering furnace may cause the cooling system of the equipment to fail, making it difficult to effectively control high-temperature equipment. Excessive temperature will pose a threat to the furnace body and related equipment, which may cause damage, burning, or deformation of the equipment. This not only increases the cost of repairing and replacing equipment, but also causes production interruptions, affecting the normal operation of the enterprise. Equipment damage not only directly affects production efficiency, but may also have an impact on the production plan and delivery time of the enterprise, increasing economic and time costs.

1.3. Reduce product quality

Sudden power outage leads to a sudden drop in temperature during glass processing, causing uneven shrinkage inside the glass and affecting product quality. The product may have surface unevenness, internal cracks, and other issues, which reduce the physical and optical properties of the glass, affecting customer use and corporate reputation.

1.4. Safety hazards

The sudden power outage of the glass tempering furnace caused the equipment and production line to suddenly stop running, and the operator may face unfinished high-temperature equipment, increasing the safety hazards at the work site. In addition, sudden power outages may also render emergency stop devices ineffective, increasing the probability of accidents and posing a potential threat to the personal safety of operators.

2. Emergency response measures for sudden power outage of tempering furnace

2.1. Protective glass: For glass that has been placed in a tempering furnace, it should be transferred to a cooling room or other relatively mild environment as soon as possible to reduce the stress caused by temperature difference and reduce the risk of glass fracture.

2.2. Equipment cooling: The internal equipment of the tempering furnace needs to undergo rapid and orderly cooling. The cooling system can be manually operated or backup cooling equipment can be used to lower the furnace temperature and reduce the possibility of equipment damage.

2.3. Backup power supply startup: In the event of a sudden power outage, start the backup power supply or backup power equipment as soon as possible to ensure the operation of the cooling system and other critical equipment, and reduce the time of production interruption.

2.4. Check the equipment status: Once the power is restored, the operating status of the internal and external equipment of the tempering furnace should be carefully checked. For components that may be damaged, timely maintenance or replacement is necessary to ensure the long-term stable operation of the equipment.

2.5. Data recording and analysis: After a sudden power outage, record and analyze key data such as temperature and equipment status before and after the outage, in order to further improve equipment operation strategies and reduce the probability of similar accidents.

In short, a sudden power outage in the tempering furnace may cause serious harm to glass processing production, so it is necessary to establish comprehensive emergency response measures and plans. By taking timely and effective measures, losses can be reduced to a greater extent, ensuring the smooth progress of the production process.
