MAGNESIA HERSYNITE BRICK

It is made from high purity magnesia clinker and hersynite as main raw material, it has good toughness and thermal shock resistance, depending on the strict control of firing temperature and firing atmosphere. It has better performance than good quality MgO chrome brick because of its good adhering to kiln coating and good corrosion resistance. It is the replacement product for burning zone of large scale dry process rotary cement kiln lining. The service life reaches more than one year.
