Good Thermal Shock Resistance Magnesia Spinel Bricks Pleonaste Brick for Cement Kiln
Introduction:
Pleonaste brick is used in cement kiln firing zone with periclase spinel brick, over-spinel brick, lithium battery three-way catalysis sag high resistance in alkaline environment; The general spinel is used for corundum spinel castable in ladle, breathable brick, nozzle, furnace lid and other parts; The aluminum-rich spinel, with good alkaline residue and good anti-permeability, is mainly used for high-performance aluminum spinel castable, and the demanding parts that RH spinel brick instead of magnesia-chrome brick.
