Glass tank reinforcements

Abstract

Compared with refractory bricks, molybdenum is far more corrosion resistant to most glass types. Therefore, cladding bricks with molybdenum sheets can protect the critieal areas (e.g. doghouse, throat channel, crosswall) of glass tanks against wear. Maintaining the form of the bricks helps to improve the glass quality and signifieantly extends the service life (campaign) of the glass tank. In order to install molybdenum parts in a cold glass tank and to protect them against oxidation during the up-tempering phase, PLANSEE developed the SIBOR® coating - the only coating which guarantees 100% oxidation protection during the heat-up (initial tempering) of the tank until the shielding is completely immersed in the molten glass.
