TRL Krosaki Refractories manufactures a wide range of basic bricks for the Steel, Copper, Glass and Lime industry.
- For Steel plants, we supply and apply basic bricks in EAF, Ladle, Convertor etc.
- For the Copper industry, our supplies are mainly for flash smelting furnace, PS Convertor, Anode Furnace, Isa Furnace and Reverbatory Furnace, Trough Furnace
- For Limekilns, we supply alumina and zirconia spinel bonded basic bricks in the burning zone of the kilns.
Major raw materials used are Magnesia, different types of High Purity Chrome, Fused mag Chrome, Graphite and Resin
Post-sintering treatment gives the material high room temperature strength and reduces permea-bility. Further, the absence of free magnesia makes it resistant to sulphate attack.
The microstructure is stabilized by a post firing treatment and remains unaffected during application at 1,200°C - 1,300°C. This also helps secondary spinel formation during use.
