Glass Industry

The raw materials are fed into the furnace where it is 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 1100°C till 600°C. Once the glass passes out of the Tin bath it passes into the Annealing Lehr where it is subjected to cooling so that glass becomes resistant to strain, doesn’t crack, and most importantly cut ability of the glass will be good. Once the glass is properly annealed it exits the Lehr and then the glass is cut by machines and transported. The regions within the float glass manufacturing process where temperature measurement is crucial are Working tank, Canal, Tin bath and Annealing lehr.
