Bauxite Raw Ore of Alumina Silicate Refractory Used as Materials for Refractory Products and Casting Material

1. Product Introduction

Bauxite (aluminous soil; bauxite),one of raw materials of alumina silicate refractory, also known as alumina or bauxite, hydrated alumina containing impurities, main component is its composition of alumina is extremely complex, a variety of geological sources vary the floorboard of the hydrous alumina ore.As water soft diaspore, monohydrate hard diaspore and sanshui diaspore (Al2O3 · 3 H2O);Have a plenty of diaspore and kaolinite (2 sio2, Al2O3, 2 h2o) company;Some is given priority to with kaolinite, and with higher content of kaolinite, the form for general bauxite or kaolinite clay.Bauxite is generally formed by the chemical weathering or exogenous, there are few pure mineral, mineral always contains some impurities, more or less contain clay minerals, iron ore, titanium minerals and clastic heavy minerals, etc.

2. Product Applications:

a. Aluminium metallurgy

b. Precision casting / Investment casting: bauxite grog fines can be made into mold for precision casting.

c. Refractory: high alumina bauxite’s refractoriness can reach 1780°C.It is charactered by good chemical stability and mechanical performance. (Al2O3 ≥48% with low Fe2O3)

d. Aluminium silicate refractory fiber: The high alumina bauxite grog can melt under 2000°C-2200°c in the electric arc furnace.After a series of processing, it can become aluminium silicate refractory fiber, which can be made into fiber blanket, plate,cloth.

e. Mixing magnesia and bauxite grog with binders to pour the molten steel ladle for better overall lining performance.

f. Producing bauxite cement

g. Abrasives

h. Ceramics industry

i. Chemistry industry for all kinds of aluminium compound.

The Highlight of Our Mine Company

5. The package

Our mine company established in 2003,and its trade company ,Qingdao Jinjunxuan International Trade Co.,Ltd,founded in 2018, relying on the group's logistics advantages and rubber trade experience, Jinjunxuan international has been shouldering the responsibility of group logistics business development and model transformation since its establishment.

In 2019,  In view of the fierce competition in the raw material market, we pay more attention to the quality of products and firmly believe in the concept of "quality-oriented, honest operation". We also rely on  mine company technical advantage to develop customized products.

Using our product, the casting is easy to be shelled, not deformed, not easy to shrink, with good finish and high yield. After that, remind the customer not to be greedy for cheap choice of cheap sand so as not to affect the casting finished products.

It is recommended to choose the products of regular mullite manufacturers with reasonable price, quality and more guarantee. We hope that through our efforts and careful service, we can provide customers with cost-effective products and contribute to the development of the investment casting industry.
