Hign Alumina Bricks high quality

Product Description:

In aqueous alumina minerals (monohydrate diaspore, sanshui diaspore, etc.) as the main composition of high bauxite;

The family of sillimanite minerals (including kyanite, andalusite, sillimanite, etc.);Synthetic raw materials, such as industrial alumina, synthetic mullite, fused corundum and so on.China high alumina bauxite resources, quality is good, producing area are mainly distributed in shanxi, henan, hebei, guizhou,

shandong and other places.Produced by high aluminium vanadium and soil, mainly diaspore monohydrate (alpha Al2O3 · H2O) and kaolinite and the mixture of two kinds of minerals.\ n high bauxite with rotary kiln and vertical kiln calcination, sintering temperature of 1500 ~ 1700 ℃.

Sintered bauxite, bibulous rate is in commonly 4 to 7%。

3 oxidation 2 aluminium (Al2O3) content higher than 48% of the silicate aluminum refractory products.Such as Al2O3 content higher than 90%,

called corundum brick.Due to different resources, the national standard is not entirely consistent.Such as European countries for high aluminum

refractory Al2O3 content lower limit is 42%.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.
The raw material According to the resource conditions and different requirements for products, can use the following categories of the material: with water alumina minerals (monohydrate diaspore, sanshui diaspore, etc.) as the main composition of high bauxite;The family of sillimanite minerals (including kyanite, andalusite, sillimanite, etc.);Synthetic raw materials, such as industrial alumina, synthetic mullite, fused corundum and so on.China high alumina bauxite resources, quality is good, producing area are mainly distributed in shanxi, henan, hebei, guizhou, shandong and other places.Produced by high aluminium vanadium and soil, mainly diaspore monohydrate (alpha Al2O3 · H2O) and kaolinite and the mixture of two kinds of minerals.
High bauxite with rotary kiln and vertical kiln calcination, sintering temperature of 1500 ~ 1700 ℃.Sintered bauxite, bibulous rate is in commonly 4 to 7%.
