Hot Corrosion Resistance of Aluminosilicate Refractories – Comparative Tests in the Secondary Combustion Chamber of a Hazardous Waste Incinerator

This paper presents the alkali and sulphur vapour corrosion resistance of aluminosilicate refractories under industrial conditions. Aluminosilicate refractory samples with Al2O3 contents ranging 42–90 mass‑% were exposed for 8 months to the corrosive atmosphere in the secondary combustion chamber (gas temperature approx. 950 °C) of a hazardous waste incineration facility.

Development and Application of Andalusite-Based Bricks for the Rotary Hearth Furnace of a Wheel and Axle Plant

High alumina bricks with superior RUL (refractoriness under load), high thermal shock resistance and high volume stability have been developed as an alternate refractory material to imported semi-silica bricks to use in sprung arch type roof of rotary hearth furnace of the wheel and axle plant of Durgapur Steel Plant/IN.
