High Alumina Bricks For Carbon Roasting Furnaces

Description

High alumina bricks for carbon roasting furnaces are aluminum silicate refractory bricks with Al₂O₃ content greater than 48%. The production process is similar to clay refractory bricks. According to different grades of bauxite clinker, different quality requirements, and formula binders The selection and distribution of appropriate proportions are formed by pressing bricks and then calcined.

Features

High refractoriness
Anti-acid
Anti-alkaline slag
Anti-corrosion and oxidation of molten metal, reduction reactivity, good thermal stability
