一.Features:
As a foundry aggregate, olivine isnoted for its high fusion point, low uniform thermal expansion, andits remarkable ability to resist fracture from thermal shock. Olivinehas been famous for years in producing excellent non-ferrouscastings. Today, more foundrymen are realizing that olivine worksequally well in iron, manganese and stainless steel.
二. Application:
Facing Sand in Cores and Moulds, to manufacture manganese steel castings, and to form alloys. Refractory Industry uses Olivine Sand for forming bricks and shapes, as it has a high melting point, moderate thermal expansion, and stable crystalline structure.Temperature-loadable moulding sand in foundry.
For Sand Blasting.
