Refractory bricks for Electrical Furance

Compared with other firebricks,MgO-c bricks have high rfracorinessgood slag- erosion resistance andspalling resistance,and are widely lined in wall of electrical furnace and ladle with severe conditions.For permanent ining MgO firebrick is usually used to save cost.
