Export high alumina brick T3 is a kind of refractory material, the main composition of this refractory brick is Al2O3.
If Al2O3 content is above 90%, it is called corundum brick. Due to different resources, national standards are not completely consistent. For example, European countries have set the Al2O3 content lower limit of 42% for high aluminum refractory materials. In China, according to the high alumina bricks are usually divided into three classes: Al2O3 content in Ⅰ etc. ─ ─ the Al2O3 content > 75%. Such as Ⅱ ─ ─ Al2O3 content is 60 ~ 75%; Such as Ⅲ ─ ─ for 48 ~ 60% Al2O3 content.
According to different resource conditions and product requirements, the following types of raw materials can be used: high bauxite mainly composed of hydrous alumina minerals (bauxite, bauxite, etc.); Sillianite group minerals (including bluestone, andalusite, sillianite, etc.); Synthetic raw materials, such as industrial alumina, synthetic mullite, fused corundum, etc. China's high-alumina vanadium soil is rich in resources and of good quality, and its origin is mainly distributed in shanxi, henan, hebei, guizhou, shandong and other places. The high-alumina vanadium soil produced is mainly a mixture of two minerals, monohydrate (-al2o3 ·H2O) and kaolinite.
