glass tempering furnace is a specialized piece of equipment used in the glass manufacturing industry to temper glass, making it stronger and safer than untreated glass through a specific process. The core of the tempering process lies in heating the glass to a high temperature close to the softening point and then cooling it rapidly, thus creating a pre-stress within the glass, which can significantly improve the strength and durability of the glass. The technical parameters of the glass tempering furnace, like the scales on a precision instrument, directly determine the final quality of the tempered glass, and they are inextricably linked.
To this end, we will be from five key dimensions, the glass tempering furnace technical parameters for in-depth analysis:

1.temperature setting:

Temperature control during the tempering process is critical. Heating temperature needs to be set precisely to ensure that the glass can be uniformly heated to close to the softening point. At the same time, the temperature stage is also critical, it helps to eliminate the temperature gradient within the glass, to ensure uniformity of the tempering effect. The cooling temperature determines the cooling rate, which in turn affects the size and distribution of the prestress. Different types of glass require different temperature settings due to differences in composition, thickness and thermal conductivity. Therefore, in practice, the temperature parameters need to be flexibly adjusted according to the specific type and specification of the glass.

2. time settings:

Time parameters also have an important impact on the tempering effect. Heating time needs to be long enough to ensure that the glass can be fully heated; heat time should be determined according to the thickness of the glass and the heating rate to ensure a uniform distribution of temperature; cooling time needs to be rapid and stable to ensure that the pre-stress can be correctly formed. Different types of glass require different time settings due to their different thermal response characteristics. Therefore, in practice, the heating, heating and cooling times need to be accurately controlled to obtain the best tempering effect.

3.Furnace chamber pressure and fuel-air ratio setting:

Furnace chamber pressure has a direct impact on the heating efficiency and quality of glass. Appropriate chamber pressure helps to speed up the heating rate and improve the heating efficiency. At the same time, the furnace chamber pressure also needs to be matched with the cooling system to ensure that the glass in the cooling process can quickly cool down, the formation of a stable pre-stress. Fuel-air ratio is related to the completeness of combustion and the efficiency of energy utilization. Reasonable fuel-air ratio helps to reduce the pollutants produced by combustion and improve the efficiency of energy utilization. In practice, the furnace chamber pressure and fuel-air ratio need to be flexibly adjusted according to the type of glass, specifications and production requirements.
Furnace pressure is generally set to 0.2-0.6MPa, in order to ensure that the heating rate and heating efficiency of the balance; fuel – air ratio is usually set to 1.05-1.2, in order to meet the needs of the complete combustion; combustion air volume is generally 16,000-32,000Nm³/h, in order to ensure that the stability of the gas flow in the furnace chamber and uniformity.

glass tempering furnace is a specialized machine used to strengthen glass by heating and rapid cooling, creating tempered glass that is more durable and safer than regular annealed glass. The process involves precise control of temperature and cooling to induce compressive stresses on the glass surface. Here’s how it works:

1. Pre-Processing

Before entering the tempering furnace:

Cutting and Edging:

Glass sheets are cut to the desired size and edges are smoothed to prevent breakage during tempering.

Washing:

Glass is thoroughly cleaned to remove dirt and contaminants that might affect the heating and cooling process.

Inspection:

Glass is checked for defects like chips or cracks that could cause failure during tempering.

2. Heating Stage

Loading:

Glass sheets are loaded onto a conveyor system or rollers that transport them through the furnace.

Heating Chamber:

Glass is heated to a temperature of approximately 620–700°C (1148–1292°F), depending on the type and thickness of the glass.

Uniform Heating:

Electric or gas-fired heaters provide consistent and uniform heat.

Convection and/or radiant heating ensures the glass reaches its softening point without deforming.

Temperature Control:

Sensors monitor the glass temperature to avoid overheating or uneven heating.

3. Soaking Period

Thermal Equalization:

Glass is held at the target temperature for a short period to ensure the entire sheet is uniformly heated.

Proper soaking prevents stress imbalances during the cooling phase.

4. Rapid Cooling (Quenching)

Cooling System:

The heated glass exits the furnace into the quenching section, where high-velocity air jets cool it rapidly.

Air Nozzles:

Jets of cool air are blown onto both surfaces of the glass simultaneously.

Stress Induction:

The rapid cooling causes the outer surfaces of the glass to contract quickly, creating a layer of compressive stress.

The interior cools more slowly, resulting in tensile stress at the core.

Controlled Cooling:

The process is carefully controlled to avoid cracking or deformation.

5. Unloading and Inspection

The glass tempering process is a method used to strengthen glass, making it much more resistant to impact, thermal stress, and breakage. The process involves heating the glass to a high temperature and then rapidly cooling it to create internal stress, which increases the glass’s strength.

Steps in the Glass Tempering Process

Glass tempering furnace

Cutting and Shaping

The glass is first cut and shaped to the desired dimensions. It’s important that all edges are smooth because sharp edges can result in weaknesses during the tempering process.

Heating

The glass is heated to a temperature between 600°C (1112°F) and 650°C (1202°F). At this stage, the glass becomes soft and malleable, but it doesn’t melt.

Quenching (Rapid Cooling)

After the glass reaches the desired temperature, it is quickly cooled using high-pressure air jets. The cooling happens very quickly, typically within 1 to 2 minutes.

Outer Surface Cooling: The outer surfaces of the glass cool down rapidly, solidifying quickly.

Inner Core: The inner part of the glass cools more slowly, creating a compression layer on the outer surface and tension inside the glass.

Strengthening

This combination of compressed outer layers and tension inside gives tempered glass its characteristic strength. The compressive stress makes the glass much more resistant to cracks and breakage.

Edge Inspection and Quality Control

After tempering, the glass is checked for quality. If the glass has any defects, it may need to be discarded or reprocessed. Additionally, tempered glass cannot be cut or altered after tempering without compromising its strength, so this inspection step is important before final installation.

Characteristics of Tempered Glass

Glass tempering furnace

Strength: Tempered glass is approximately 4 to 5 times stronger than regular, annealed glass of the same thickness.

Safety: When tempered glass breaks, it fractures into small, blunt pieces instead of sharp shards, reducing the risk of injury.

Thermal Resistance: Tempered glass is more resistant to thermal stress and can withstand temperature differences up to about 200°F (93°C) without breaking.
