SCL offers following refractories for hot-repair of the furnace:

Fused Silica Refractory and Patching Mass

• Fused Silica refractory has excellent thermal shock resistance and is used for hot repair of silica roof. Silica patching mass provides complete sealing of silica roof by developing ceramic bond. The sealing of roof prevents further soda deposition and corrosion of refractory by preventing escape of hot gases from the roof.

Alumina-Chrome Refractory

• Alumina-chrome tiles are used for hot patching of AZS blocks at glass level. These tiles can be installed without undergoing any thermal spalling. This refractory has excellent corrosion resistance and lasts for a very long time without needing further repairs. This does not cause any coloration.

Zircon and Zirmul Patching Material

• These are monolithic materials required for patching various areas of the furnace and are required mostly in the second-half of furnace life.
