Product Descpription:
“Nice Foundry Sand” serial Foundry material products are high-quality aux foundry materials that can improve quality as well as cut down the energy-consuming and environmental pollution. Its major characteristics are as follows:
Ⅰ.Major parameter of the Nice Foundry Sand (NFS):
1.Main Chemical element: AL2O3≥75% Fe2O3≤5% Tio2：2.5%-3.5% SiO2：8-12% else: tittle.
2.Shape: Ball Shape
3. Shape Coefficient：≤1.1, very close to ball
4. Density: 1.95-2.05 (g/cm3)
5.Fire-retardant temperature: ≥1820℃
6.Heat dilating rate: 0.13%（Heated up for 10 Minutes at 1000℃）
Ⅱ. Excellence of NFS:
1.Very good shape. Shape Coefficient≤1.1, very close to ball, can decrease by 40% of the usage of felted dosage, strengthen the fluidity, increase the recycling using, cut down the wasting.
2.High Fire-retardant temperature: Fire-retardant temperature ≥1820℃, avoiding greatly the adhibiting of the sand, improving the quality of the foundry wares’ quality, while decreasing the cleaning works of foundry at the same time.
3.High anti-pressure character and stable volume: NFS need to mould through electronic furnace, and its anti-pressure can reach 80GPa, line dilating Coefficient is 0.156×10-6. It can efficiently guarantee the size of the foundry wares, cut down the disfigurement, and hard to put into powder that help to keep away the pollution.
