Olivine Sand

Application of olivine sand:

1.High quality olivine sand EBT for refractory
2.EBT-Electrical Arc Furnace Tapping Hole Filler
3.Abrasive blast cleaning,
4.foundry sand,
5.refractory,
6.abrasive in water jet cutting industry,
7.welding electrodes,
8.facade cleaning

Features:
1. Compared with Zircon sand, brown sapphire, quartzes, olivine foundry sand product has no phase transition from room temperature to the 1900 melting point, olivine sand has stable thermal property, good fragility, strong adhesive force, olivine sand can produce a smoother surface.
2. Olivine for foundry sand product has no radiation or damage of free SiO2 powder, so it can eliminate the possibility of anthracosis, olivine sand is environmental friendly.

3. The coating has good density and permiability, the casting will not adhere to the sand, olivine sand is easy to clean up afterwards, so labor cost will be reduced.
