High aluminum hook brick
High aluminum hook brick
Product advantages: low temperature creep, strong corrosion resistance, good thermal shock stability
deskripsi produk
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.
Proses produksi bata alumina sing dhuwur lan bata lempung multi-klinker padha. Bedane yaiku proporsi klinker ing bahan sing luwih dhuwur, sing bisa nganti 90-95%. Klinker kudu diurutake lan ayak kanggo mbusak zat besi sadurunge remuk, lan suhu tembakan sing luwih dhuwur, kayata Ⅰ, icks bata alumina sing umume umume 1500 ～ 1600 ℃ nalika dipecat ing tungku trowongan.
