the magnesia hercynite brick was prepared with hercynite as raw materials. The application results showed that the kiln coating formed rapidly and stability when using magnesia-hercynite brick. The magnesia-hercynite brick had low thermal conductivity and long service life, and its overall performance was better than magnesia-chrome brick. The magnesia-hercynite brick could satisfy the chrome free requirement of burning zone of large-scale rotary kiln.
