Product Description
Product Description of Rongsheng Good Quality High Alumina Checker Firebrick for Steel Furnace and Cement Rotary Kiln
High alumina checker firebrick is a type of refractory material that is used in a variety of high-temperature applications. It is made of a high percentage of alumina (Al2O3), which gives it its high refractoriness and strength. High alumina checker firebrick is also resistant to corrosion and abrasion.
High Alumina Checker Firebrick Features & Advantages
1. High refractoriness.
2. Good spalling resistance and wear resistance.
3. Good corrosion resistance.
4. Good thermal shock resistance.
5. High mechanical strength.
6. High-temperature creep rate is low
