Special Acid-proof refractory bricks/ Used for fluidized bed/High refractoriness under load, good wear resistance
Product description:
The special acid-proof refractory bricks are developed for the special working condition of fluidized bed chlorination reactor for producing titanium dioxide. It is made by using compound materials of fused mullite,andalusite and sillimanite from Linzhou as main raw materials and adding special additives,through pressing and firing at high temperature.
Features:
The product has excellent features of acid resistance,low water absorption, high refractoriness under load, good wear resistance and thermal shock resistance,etc
