The JX special corundum composite multifunctional hanging assembly (JXSN-A006) for cement kiln hoods is our company's newest functional product. Using composite masonry technology and dedicated installation equipment, it solves the fatal defects of refractory castables and silica-mullite bricks — alkali cracking, expansion cracking, collapse and air leakage — at high temperature. It has a dense structure, low thermal expansion, high overall strength, resistance to erosion and corrosion, good insulation and energy saving, convenient replacement and long service life.
