Application:
Raw materials for breathable bricks, seat bricks, spray guns, impact plates, etc. Those prefabrications produce by tabular alumina are not only part of the refractory lining of the ladle, but also play a very important role in the steelmaking process itself. Adopting tabular alumina will increase the wear resistance and corrosion resistance of those products.
