      Magnesium-iron spinel brick (MTJ) is the main raw material of high purity magnesium sand and aluminum spinel, strictly controlling the temperature and atmosphere of sintering, so that the product has good flexibility and thermal shock stability. The performance and corrosion resistance of hanging kilns exceed the high quality magnesium-chrome brick. This product is a replacement for the lining of large dry cement rotary kiln.
