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
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.
