Product Description
Specifications
1. few impurity content2. high firing temperature
3.high direct-bonding rate of high -temperature mineral facies
The direct-bonded magnesia-chrome brick, belonging to burned product that takes top-grade magnesia and chromium concentration as raw materials, features with few impurity content, high firing temperature and high direct-bonding rate of high -temperature mineral facies. Because of its high strength, strong resistance to etching, fine thermal expansion, stability of temperature shock and high temperature property and easy to combine with hang kiln coat well, the product is widely used for the burning zone of large-size dry-process cement rotary kiln .
