High aluminum hook brick
High aluminum hook brick
Product advantages: low temperature creep, strong corrosion resistance, good thermal shock stability
Panjelasan 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.
Prosés produksi bata alumina tinggi sareng bata liat multi-klinker sami. Bédana nyaéta proporsi klinker dina bahan langkung luhur, anu tiasa saluhur 90-95%. Klinker kedah diurut sareng disaring kanggo miceun beusi sateuacan ditumbuk, sareng suhu némbakan langkung Luhur, sapertos Ⅰ, icks bata alumina tinggi biasana 1500 ~ 1600 ℃ nalika dipecat dina tungku terowongan.
