Spherical Ceramic Foundry Sand

Product Description

Ceramic Foundry sand used in the foundry industry with High finish,good permeability,High refractoriness/Casting materia

 

Product description:
 

Ceramic Foundry sand is made of high quality bauxite, which has been remelted and then blown into ball shape. Ceramic Foundry sand is a new casting material with high surface finish and good air permeability. Ceramic foundry sand is made of high quality bauxite, through the process of electrofusion, granulation, screening and so on, which is made of very ball-like refractory particles.

 

The performance characteristics:

1. Fire resistance; Composition is stable, not easy to produce chemical changes, it can reach 1900 ℃ refractoriness.

2. Liquidity; For spherical particles, its mobility is very good, modeling easy compact, and can maintain good air permeability.

3. Air permeability; The permeability of molding sand mainly depends on the size, size distribution, size and type of binder.

4. Thermal expansion coefficient; Orb of sand small thermal expansion coefficient, thermal expansion rate: 0.13% (1000 ℃ heat for 10 minutes).There is almost no expansion in the pouring process, which greatly improves the precision of the casting and its performance is comparable to that of zirconium sand.

5. Angular coefficient; Spherical ceramic foundry sand has excellent angular coefficient, so the molding sand concentration, high compactness, saving more than 60% of the cost of molding sand.

6. Reuse performance; By reducing the amount of waste sand and increasing the amount of effective recycled sand, the loss of molding sand is greatly reduced.

 

Advantage:

Spherical grain, low thermal expansion, good anti-breakness, well refractory, low density, neutral materials

1. Ceramic Foundry sand is widely used in resin sand (furan resin, phenolic resin), water glass sand (organic fat, CO2 hardening), and coated sand.

2, Ceramic Foundry sand is suitable for all kinds of metal castings such as: carbon steel, alloy steel (high manganese steel, high chromium iron), cast iron, cast copper.

3, Ceramic Foundry sand is a non-quartz type of artificial sand, suitable for various casting methods such as: V method, VRH, lost foam mold, investment mold, general sand mold (clay sand, sodium silicate +CO2 hardening), resin sand.

4, orb sand are suitable for all kinds of adhesive, all kinds of metal materials of casting production, not only can greatly improve the quality of castings, easy and deoxidization, with sand process easy and convenient.

5. Ceramic Foundry sand is suitable for polishing and cleaning of lost foam mold, coated sand, sodium silicate sand, resin sand, precision casting machine copper and aluminum castings, and the cost is quite cheap.
