In-Line Oxygen Sensors for the Glass Melt and the Float Bath

Abstract:

In-line oxygen sensors have been developed for the glass melt and for the float bath. Glass melt oxygen sensors are used for the continuous monitoring of the oxidation state (or redox) of the glass melt and are very important for the control of many glass melt and glass product properties such as radiative heat transfer, fining, foaming, forming and optical characteristics. Too high oxygen levels in the float bath can be prevented by using both oxygen sensors in the tin melt and the atmosphere above it. Oxygen related defects on the glass sheet surface such as dross, tin pick-up, bloom and tin drips are reduced or even prevented. Moreover, expensive hydrogen gas can be saved by a more effective dosage.
