low porosity clay brick
Features
It is slight acid refractory with certain anti-erosion ability for acid furnace slag,and acidity will be strengthened as the improving of Sio2content.generally,it’s soften temperature under load is above1300~1400℃，compact organization,high strength and good thermal shock stability.
Application
It was widely used in industrial furnaces like coke furnace,hot stove, lime furnace,pellet shaft furnace,submerged arc furnace,carbon furnace and roasting furnace.
