Chrome corundum series, made of Al2O3 mixing with CrO2 or ZrO2 in a certain proportion, is commonly produced with an adoption of special refractory production process.
According to the ingredients, it is usually divided into:
Chrome corundum products;
Chrome-zirconium corundum products;
Sometimes, it is made into composite products with corundum or clayey materials;
It is widely used in parts of wear resistant and wash-out resistant in metallurgy, glass, petrochemical and other industries.
The series has advantages of high refractoriness, high strength, excellent thermal shock stability, strong erosion resistance. During furnace working, it also has good abilities of resistant to washing out, abrasion, erosion and spalling.
