High aluminum hook brick
High aluminum hook brick
Product advantages: low temperature creep, strong corrosion resistance, good thermal shock stability
incazelo yomkhiqizo
High-aluminum hook bricks with alumina content above 48% are neutral refractory materials. It is formed and calcined from bauxite or other raw materials with high alumina content. High-aluminum hook bricks have high thermal stability, and their refractoriness is above 1770℃. The slag resistance is better.
Inqubo yokukhiqizwa kwezitini eziphakeme ze-alumina nezitini zobumba ezinama-multi-clinker ziyefana. Umehluko ukuthi inani le-clinker ezithako liphezulu, elingaba phezulu ngama-90-95%. I-clinker idinga ukuhlelwa futhi isuswe ukuze kususwe i-iron ngaphambi kokuchobozwa, futhi izinga lokushisa lokudubula Okuphakeme, njenge-Ⅰ, Ⅱ izitini eziphakeme ze-alumina ngokuvamile ziba yi-1500 ～ 1600 ℃ lapho zidutshulwa kuhhonela lomhubhe.
