Magnesia Alumina Zircon Brick
Introduction:
Magesia alumina zircon bricks are produced on the basis of low thermal magnesia alumina brick by adding ZiO2. Meawhile, Zircon easily reacted with CaO forming calcium zirconat with high melting point in application.
Features:
◆ The micro-porestructure inside the products improves theirs thermal shock resistance.
◆ Improves the corrosion resistance of the products and adhesion of the material in the kiln.
Application:
Calcining zone of large NSP cement kiln.
Modified Magnesia Alumina Chrome Brick
Introduction:
Modified magnesia alumina chrome bricks are manufactured on the basis of low thermal magnesia alumina bricks by adding Cr2O3.
Features:
◆ The resistance to thermal shock, corrosion and spalling, and good coating of the linning surface in the kiln.
Application:
Calcining zone of large NSP cement kiln.
