Features:
Magnesite-ferrum spinel brick and synthetic
magnesite-ferrum-alumina spinel brick are made of high purified
magnesite clinker and ferrum-alumina spinel clinker at strictly
controlled temperature and sintered atmosphere,which enables the
product to have good flexibility and temperature vibration. The
performances of attaching kiln wall and corrosion resistance are
better good quality magnesite chrome brick.the product is update
product for lining of large dry cement rotary kilns.
