What are the characteristics of LandGlass combined(double chamber) glass tempering furnaces?

Source: LandGlass  Attention: 24  Published: 2023-01-18

LandGlass combined(double chamber) glass tempering furnace has two heating sections, in which the glass goes through two different heating stages.

In LandGlass combined(Double chamber) glass tempering furnace, the glass is first preheated in the pre-heating section to avoid the abrupt temperature change. In a relatively low-temperature environment, the temperature is uniform and easy to control, allowing for even and effective heating of the glass. it will reduce quality defects such as optical distortion, spherical bending, hot spots, white haze, etc.

After being preheated in the pre-heating section, the glass enters the heating furnace; the heating furnace is usually set at about 700°C. Similarly, due to the small temperature difference, the temperature in the furnace is relatively stable. The glass enters a stable temperature environment. At this time, the glass heat absorbing efficiency,compared with the first heating stage,is weakened, which stabilizes the shape of the glass and reduces the possibility of deformation.

LandGlass combined(double chamber) glass tempering furnace  has greatly improved the yield and quality of glass, and is often used in the production of high-quality flat tempered glass for construction.
