The effect of the passing section of the glass tempering furnace on glass tempering

The glass tempering furnace is a key equipment for converting ordinary flat glass into high-strength and high safety tempered glass. Among them, the "through section" (usually referring to the quenching or cooling section) plays a crucial role in the tempering process. This article will explore the role of glass tempering furnaces in improving glass performance through stages.
