Introduction of high alumina brick:
high alumina brick is a kind of refractory material,its main
composition is Aluminum oxide (Al2O3), which containing is more
than 48%.
Application:
It is mainly used in blast furnace, hot blast stove, baking
furnace, carbon calciner, coking furnace, teeming ladle, casting
system, boiler, cement kiln, glass furnace and all kinds of kiln
linings and thermal equipment. It is applied in metallurgy,
machinery, construction, casting, ceramics, electricity, petroleum,
chemical industry, etc.

Quality Assurance:
The process from raw to product are strictly tested by equipment.
1. Inspection and Control of incoming raw materials: according to
the chemical content,raw materials are classified into different
levels to ensure quality of brick first.
2. Inspection and control of the process: during the
production,every brick will be weighed twice strictly to reduce the
error of weight .
3. Quality audit by quality management: inspection of product
standardization of quality of each product by process control and
experimentation, taking corrective measures timely whenever
deviations are noted.
4. Before delivery, the inspectors will inspect the
size,appearance, physical and chemical properties of brick again in
factory.
