鋁礬土采用優(yōu)質(zhì)高鋁礦石，經(jīng)煅燒、水洗、人工篩選、破碎、等工序精制而成，耐火度高達(dá)1780℃，常用粒度100-325目，其特點(diǎn)：膨脹系數(shù)小，耐火度高，高溫性質(zhì)穩(wěn)定，使用環(huán)保，無(wú)有害氣體排出，可替代其他非環(huán)保型價(jià)格昂貴的鑄造材料。
煅燒鋁礬土主要用途：
1.鋁工業(yè)。
2.精密鑄造。
3.耐火材料行業(yè)。
4.硅酸鋁火纖維。
5.與氧化鎂混合，是一種很好的粘接劑，特別是用于澆鑄整個(gè)鋼包鋼包襯里。
6.制造鋁土礦水泥，研磨磨料，陶瓷工業(yè)和化學(xué)工業(yè)，用于制造鋁化合物。
Bauxite is made of high-quality High Alumina Ore by calcination, water washing, artificial screening, crushing and other processes. Its fire resistance is as high as 1780 ℃, and the commonly used particle size is 100-325 mesh. Its characteristics are small expansion coefficient, high fire resistance, stable high temperature property, environmental protection and no harmful gas emission. It can replace other non environmental protection and expensive casting materials.
Calcined Bauxite Applications:
1.Aluminum industry.
2.Precision casting.
3.Refractory industry.
4.Silicic acid aluminum firefibre.
5.Mixed with magnesium oxide,it can be an nice bonding agent,especially for pouring entire steel teeming ladle lining.
6.Manufacture bauxite cement,grinding abrasives.ceramic industry,and chemical industry for making aluminum compounds.
