What is the correct use of tempering furnace convection?

Tempering furnace convection is an important heating and cooling method in glass tempering furnaces. It mainly transfers heat through the flow of liquid or gas to achieve rapid heating and uniform cooling of glass, thereby improving the strength and durability of glass. The correct use of tempering furnace convection is crucial to ensure the quality and performance of tempered glass.

Tempering furnace convection

Tempering furnace

1. Tempering furnace convection form

In glass tempering furnaces, there are two main forms of convection: natural convection and forced convection:

Natural convection: Natural convection refers to the phenomenon of spontaneous flow of liquid or gas formed due to temperature difference inside the glass tempering furnace. Hot liquid or gas becomes lighter due to heating and rises to the colder area, while cold liquid or gas sinks to the heated area, forming a circulating flow. This form of convection is relatively common in glass tempering furnaces, especially during the heating and cooling stages. Through natural convection, the temperature distribution on the surface and inside of the glass is more uniform, which helps to reduce the internal stress of the glass and improve the tempering effect.

Forced convection: Forced convection is a form of convection achieved by forcing flow through external equipment such as fans, circulating water pumps, etc. In glass tempering furnaces, forced convection is usually used in the heating stage, and the air in the furnace is forced to circulate through the fan, so that the glass is heated more evenly. This helps to reduce temperature differences, improve the heating efficiency of the glass, and ensure that the entire glass surface obtains a uniform temperature distribution. Forced convection also speeds up the cooling process, increasing the strength and impact resistance of the glass.

2. The role of convection in tempering furnaces

Promote uniform temperature distribution: Heating and cooling by convection can make the temperature inside the glass evenly distributed, avoid overheating or local low temperature, and thus ensure the quality and performance of the glass.

Improve heating efficiency: Forced convection can speed up the heating speed of the glass surface, so that the glass can reach the required temperature in a short time, and improve production efficiency.

Enhance the tempering effect: Uniform temperature distribution and rapid cooling process help to create a uniform pressure difference on the surface and inside of the glass, thereby increasing the strength and durability of the glass.

Glass Tempering Furnace Guide: Working Principle, Applications, Tempered Glass Types

The glass tempering furnace is an industrial heating equipment, also known as a glass tempering unit, tempering furnace, tempering equipment or tempering unit, etc. It mainly forms a compressive stress layer on the surface of the glass and a tensile stress layer inside by physical or chemical methods, thereby improving the strength and safety of the glass. The following is a detailed introduction to the glass tempering furnace:

Glass Tempering Furnace Introduction

Glass Tempering Furnace

1. Working principle

The working principle of the glass tempering furnace mainly includes the following steps:

Heating: In the tempering furnace, the glass is placed in the heating chamber. The heating element gradually increases the temperature in the furnace through resistance heating or other means, so that the surface and inside of the glass reach the tempering temperature (usually about 650℃).

Wind quenching cooling: Once the glass reaches the tempering temperature, the wind quenching device will quickly blow cooling air to the surface of the glass, so that the surface cools rapidly, while the inside remains at a high temperature. This creates a temperature difference between the surface and the inside, thereby generating compressive stress on the surface of the glass and tensile stress inside.

Internal cooling and stress balance: After wind quenching cooling, the temperature inside the glass begins to slowly drop and gradually become uniform. In this process, tensile stress is formed inside the glass, which is balanced with the compressive stress on the surface to form a strong overall structure.

2. Main features

High efficiency: The glass tempering furnace has a fast processing speed, which can greatly shorten the production cycle and improve production efficiency.

Good stability: It has the characteristics of high temperature control accuracy and stable processing quality, which can ensure that the products processed by glass are of higher quality.

Large processing range: It is suitable for the processing of a variety of glass products, such as architectural glass, furniture glass, automotive glass, etc.
