Mullite Sand of Flint Clay Used for Casting Sand Especially Precision Casting with Low Thermal Expansion

1. Description:

Mullite is made of kaolin by high temperature sintering.

The chemical components of mullite are all chemical substances with strong fire resistance, and their properties are relatively stable.

It mainly includes: alumina, silica, etc., the content of alumina is between 42% and 46%, and the content of silica is between 51-53%. In addition, there are less substances: iron oxide, sodium superoxide, potassium superoxide, titanium oxide, magnesium oxide, etc

2. Application:

Refractory sand is widely used in investment casting, gypsum filling V method and vacuum suction casting, as well as large, medium and small steel casting, copper casting, furnace lining refractories, as well as water glass, refractory products, concrete materials, etc. Widely used in machinery, aviation, weapons, metallurgy, petroleum, heat preservation, sintering, construction and other industries

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.
