PHOSPHATE BONDED MONOLITHIC REFRACTORY MATERIALS WITH IMPROVED MECHANICAL AND CHEMICAL RESISTANCE FOR APPLICATIONS IN THE ALUMINUM INDUSTRY

摘要

Phosphate bonded bricks have long been used in the aluminum industry because of their high impact resistance, non-wetting properties, alkali resistance and relatively high tensile strengths. Although cement bonded monolithic refractory products have replaced bricks in many applications due to the faster and more efficient installation time, some equipment owners are still reluctant to replace phosphate bonded brick linings in applications with severe physical and chemical wear. In this paper a new type of phosphate bonded monolithic material with the potential to replace phosphate bonded bricks will be presented and the differences to conventional cement bonded monolithic materials will be explained.
