Ceramic Nice Foundry Sand
Ceramic Foundry Snad, also known as Nice Foundry Sand (NFS), Baozhusha in Chinese Pronunciation, which means pearl sand. It is a kind of artificial foundry sand with granular shape, high heat-resistant, low heat dilating rate. NFS is the senior substitute of silica sand which is mainly made of Al2
, and treat through high temperature calcined, fused, prilling and selecting. NFS has advantage of lower cost and better performance than Chromite sand and zircon sand.
Ceramic foundry sand provide the effective ways to improve the quality of the foundry with less damage to the environment.
1.Main Chemical Element:
≥75% , Fe2
5%-20%, Else: slight.
2. Shape: granular
3. Angle Factor: ≤ 1.1, very close to ball shape.
4. Bulk Density: 1.95-2.05 (g/cm3
5. Refractoriness: ≥1790℃
6.Thermal Conductivity: 5.27W/M•K(1200℃)；
7.Thermal Expansion : 0.13%（10 minutes at 1000℃）
Advantages of NFS Ceramsite:
1. Less thermal expansion, so it makes the foundry more precisely, less cracking and high output. Improving foundry quality.
2. The shape of ceramic foundry sand is spherical with smooth surface and lower specific surface area so that can make the adhesive covered uniform. It has very good air permeability, good liquidity and good filling ability that can make the surface of foundry castings perfect when founded.
3. Ceramic foundry can flow very easily and easy to clean. Reducing usage amount of adhesive.
4. Ceramic foundry sand is a neutral material, so acid, alkali binder can be used.
5. Lower cleavage breakage rate: ceramic foundry sand has high density, very low cleavage breakage rate.,easily reclaimed and these makes it more environmently friendly.
6. High refractoriness and service temperature can reach 1900°C, much higher than Chromite Sand.
7. Recycle and regeneration use, cost-effective, cheaper than Chromite Sand.
