Product Details
We are offering Olivine Sand.
Olivine Sand, as a foundry and refractory aggregate, olivine is noted for its high fusion point, low uniform thermal expansion, and its remarkable ability to resist fracture from thermal shock. Olivine has been famous for years in producing excellent non-ferrous castings, monolithic and basic Refractories and a key raw material for Manganese Steel Castings. Today, more foundry men are realizing that olivine works equally well in Cast Iron and Stainless Steel.
Applications
- Refractory sand, manufacturing manganese steel castings and to form alloys.
- Refractory industry uses Olivine Sand for forming bricks and shapes, as it has high melting point, moderate thermal expansion and stable crystalline structure.
- Temperature- loadable molding and facing sand in foundry.
- Replacement of Garnet Sand for shot blasting.
- As EBT tape hole filler in steel plants for Electric Arc Furnace.
