Foundry Mullite Sand 16-30mesh For Investment Casting And Refractories With Good Finishing

 

1. Mullite Sand Introduction

 

Natural mullite crystals and needles are radially elongated clusters. Mullite quarry is used to produce high temperature refractory material.The density of mullite 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.

5. Mullite Sand Applications

 

The product can be used for complex casting of carbon steel, stainless steel, heat-resistant steel.
1.Grain shape of the foundry sand is close to the true round with smooth surface, good fluidity and fillibility, easy to be filled ,it can get good formability and strength of mold.
2.Foundry sand has a good collapsibility, easy to carry out the sand cleaning operation. The usage amount of binder is more less than other types of sand.
3.Compounding moulding sand with foundry sand, casting will not have defects of expansion cause it has low thermal expansion rate.
4.Producing castings with foundry sand will have high accuracy ,less fracture and surface defects, what's more it can also improve the yield of casting.
5.Foundry sand has good crushing resistance and high strength, it's rarely broken even if reuse.
6.The foundry sand with good reproducibility can reduce dust pollution in the production process and industrial waste emissions,is conducive to environmental protection.
