Container Glass Temperature Measurement Solutions for Quality and Efficiency

Container Glass Temperature Measurement is a key factor in ensuring quality, consistency, and efficiency throughout the glass manufacturing process. The raw materials are fed into the furnace, where they are melted at a temperature of around 1500°C. The molten glass is then transported to the tin bath through a canal. The glass floats on the tin surface like a ribbon. As the glass flows through the tin bath, its temperature drops from approximately 1100°C to 600°C.

Once the glass exits the tin bath, it enters the annealing lehr, where it is gradually cooled to relieve internal stresses. This ensures the glass is resistant to strain, does not crack, and—most importantly—can be cleanly and accurately cut. Once properly annealed, the glass exits the lehr, is cut by machines, and transported for further processing.

Crucial zones for accurate temperature monitoring in the float glass manufacturing process include the working tank, canal, tin bath, and annealing lehr.
