Product Description

High-grade Magnesia Aluminum Spinel Refractory Brick For cement rotary kiln

 

Material and Technique

 

It takes good quality fused magnesite and fused mgo clinker as raw material, formed under high pressure,burned in high
temperature. It has character of corrosion resistance.Main using for cement rotary kiln.

 

In order to form direct bonded, the SiO2 content in raw materials is best to low, and that the sintering temperature must be raised to about 1700ºC.
