Olivine Sand

Introduction-

Olivine sand also known as Dunite in India, as a foundry and refractory aggregate, it 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 and alloy castings. Olivine Sand is widely consumed in Refractory industries for producing basic refractory products along with dead burnt magnesite, steel plant operating with electric arc furnace. Olivine sand is used as Taphole Filling material.
