Glass Industry

Container Glass

The raw materials are fed into the furnace where its 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.

1. Application: Working Tank

2. Application: Feeder / Forehearth

Recommended Product: AST 450G2

The AST 450G2 is the right solution for the monitoring of temperature in the Fore hearth. The fast response time is useful in monitoring changes in temperature range. Pyrometer contains small optical head which makes it easier To reach the harsh locations and the Fiber Optic Cable can withstand ambient temperature up to 250°C very easily. The accessory such as air purge unit helps in purging and keeps the optical lens clean and the mounting system provides proper support to the pyrometer.

450-G2 Pyrometer

3. Application: Glass Gob

Recommended Product: AST A450C FO/PL

Efficient temperature control helps in achieving the desired container wall thickness. An infrared pyrometer achieves the correct gob temperature before entering the next stage. This application demands fast-acting infrared pyrometers. The two-color pyrometer provides a response time of 20 ms. A pyrometer with a water cooling jacket is recommended for this application.
