Olivine and olivine-chrome products
Olivine and olivine-chrome products are made on the basis of calcination of pure olivine. According to different chemical composition and heat treatment, it can be divided into calcined olivine, non calcined and calcined olivine-chrome products, which are used for laying heat accumulator’ nozzles, walls, vaults and sediment chambers of steel-making furnaces and other heat equipment (GB 14832-96).
