16-30 Mesh Precision Investment Casting Sands with High-alumina Low Thermal Expansion Coefficient

 

 

Our company:


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". Our company is mainly engaged in 16-30 mesh, 30-60 mesh, 200 mesh,high-quality mullite and mullite powder, and we can produce the required specifications according to customers' requirements, professional factories, quality assurance, reasonable price, perfect service, welcome new and old customers to inquire.
 

1.  Product Description:

 a. Our casting sands are made from mullite or kaolin.

 

 b. The density of mullite or kaolin raw ore is generally greater than 2.5g/m3, the true specific gravity is 2.6g/cm3, the water content is less than 0.03%, and the fire resistance is greater than 1750 ℃. Under the condition of high temperature burning, its weight will be reduced by 0.3% and not more than 0.4%, which shows the stability of mullite's chemical properties. Its pH value is between 7 and 9, and the hardness of the shell is greater than 8 MPa.

 

c. The casting sand is made of kaolin by high temperature sintering. The chemical components  are all chemical substances with strong fire resistance, and their properties are relatively stable.The content of alumina in the casting sand is between 43% and 46%, and the content of silica is between 51-53%,which make the casting sand can keep low thermal expansion and keep a good model shape.

 

 d. The grain size of casting sand is also different for different purposes. Generally, we use "mesh" to measure the grain size of mullite, including16 to 30 mesh, 30 to 60 mesh,;mullite powder mainly includes 200 mesh and 300 mesh.We also can produce the special casting sands for your order.

 

e. Our product high-alumina investment casting sands  is a series of mullite sand and powder with high aluminum content, low iron content, low coefficient of thermal expansion, high refractoriness and stable thermochemical proprities, which are made of hard clay mineral resources through high-temperature roasting, crushing, screening, Raymond, iron removal and other machining processes.

2. Product Application:

 

The products are mainly used in investment casting,especially in reinforcement layer, gypsum filling V method molding and vacuum suction casting, as well as refractories for large, medium and small steel castings, widely used in machinery, aviation, weapons, metallurgy, petroleum and other industries.

 

In investment casting field,the casting sands are different for different purpose.

16-30 mesh precision Investment Casting Sands with High-alumina Low Thermal Expansion Coefficient is needed in the reinforcing layer.

 

Please choose the right mesh product for your purpose.
