Quartz Infrared Heating Element For Glass Heat Treatment Process

Sep 14,2022

As glass application trends go bigger and bolder, heat treating has never been more important. So high efficient and stable infrared heating is widely used for heat-strengthened glass and annealed glass.

Annealing is a heat treatment process for materials, which refers to slowly heating the material to a certain temperature, keeping it for a sufficient time, and then cooling it at a suitable speed. The material includes metal materials and non-metal materials.

As its heated, the glass expands. Glass is cooled with air, the cooler outer layer contracts faster than the warmer interior. This creates tension that persists as the glass cools completely. That’s removing glass stress.

Annealed glass can be cut in different pieces, heat treated glass can be laminated, can be bent, can be handled in many ways.

Different types of glass have different annealing processes, and the annealing temperature ranges from hundreds to thousand degrees C. Our quartz infrared heating lamps can be customized according to the size of the drying tunnel, and the heating power can be customized to achieve different annealing temperatures. Since glass easily absorbs 2-4 micron infrared lamp medium wave, medium wave twin tube infrared heating lamp is our recommended heating lamp with high efficiency, energy saving and no pollution.
