铝矾土

铝矾土经过高温煅烧而生成高铝矾土,用途非常广泛:

(1)炼铝工业:用于国防、航空、汽车、电器、化工、日常生活用品等。

(2)精密铸造:翻土熟料加工成细粉做成铸模后精铸。用于军工、航天、通讯、仪表、机械及医疗器械部门。

(3)用于耐火制品:高铝矾土熟料耐火度高达1780。C,化学稳定性强、物理性能良好。

(4)硅酸铝耐火纤维:具有重量轻,耐高温,热稳定性好,导热率低,热容小和耐机械震动等优点,用于钢铁、有色冶金、电子、石油、化工、宇航、原子能、国防等多种工业。

High-grade bauxite is made from bauxite which is sintered by high temperature, it has widely using:

1)Aluminum metallurgy industry: for the national defense, aerospace, automobile, electrical, chemical and other daily necessities.

2)Casting: from clinker to powder, then casting to mold and go on casting to better. It can be used in military, aerospace, communications, instrumentation, machinery and medical equipment sectors.

3)For refractory products: the refractoriness of high-grade bauxite reaches to 1780℃,. It has high chemical stability and physical performance.

4)Aluminum silicate refractory fiber has many advantage such as light weight,high temperature resistance,good thermo stability,low thermal conductivity,low heat capacity,mechanical shock-resistant and so on. It can be used in varied industries such as steel industry,non-ferrous metallurgy,electronic industry,oil industry,chemical industry,astronautics industry,atomic energy,national defense,etc.
