Cost-effective Mullite Foundry Sands to Partial Replace of Zircon Sand for Precision Investment Casting
1. Brief introduction of 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". We also cooperate with mining companies 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.
2. Product description
a. The refractory foundry sands are made of flint clay.Flint clay is a kind of high quality hard refractory clay produced in Zibo area, Shandong Province, China. The Al2O3 content of the standard raw ore is 38%, the Al2O3 content after calcination is about 44%, Fe2O3 < 2%. It has stable composition, uniform texture, compact structure, shell shaped section and white color, and is used to produce high-quality clay refractories. The technical term is first-class hard clay clinker, the main chemical composition is Al2O3 and SiO2, with a small amount of Fe2O3 and a small amount of Na2O and K2O, and the main mineral is kaolin.
Flint clay
b. Main properties of foundry sands of Zirconium substituted sand:
① the refractoriness is above 1800 ℃, which is much higher than that of enstatite sand. The chemical stability at high temperature is much better than that of silica sand. It can be used for cast steel, cast iron and various non-ferrous alloys.
② it is a kind of electric melting material with compact texture and better durability than sintered ceramsite.
③ after heating, the expansion rate is about 1 / 5 of that of silica sand, which is roughly the same as that of zircon sand, slightly lower than that of chromite sand. As a molding material, it can effectively prevent expansion defects of castings.
| Specific gravity | Hardness | Stacking density | Melting point | LOI index | Thermostabilty | Particle size | |
| 4.6-4.8 | 7.0-7.5 | 2600-2800kg/m3 | 2100-2300℃ | <0.3% | 1700℃ | 110 mesh |
