| Our SPINEL grains are produced from high purity raw materials in electric arc-furnaces to obtain maximum amount of spinel crystals. The molten material undergoes cooling, crushing, grinding, sieving, classifying and, of course, various quality checkings before it is packed for delivery. As a final product, we distinguish between grades of FS-10, FS-27 and FS-33 in accordance with the MgO percentage these products contain. |
| FS-10: We recommend our FUSED SPINEL FS-10 for the production of refractory materials for: the sinter and transit zones of rotary furnaces in the cement industry, the arches of electric arc-furnaces, the refractory lining of high frequency furnaces, the refractory lining of torpedos and ladles in steel works. | FS-27: We recommend our FUSED SPINEL FS-27 for the production of refractory materials for: the sinter and transit zones of rotary furnaces in the cement industry, the arches of electric arc-furnaces, the refractory lining of high frequency furnaces, the refractory lining of torpedos and ladles in steel works, the refractory lining of Aluminium refining furnaces, the crowns of glass melting furnaces. | FS-33: We recommend our FUSED SPINEL FS-33 for the production of refractory materials for: the sinter and transit zones of rotary furnaces in the cement industry, as component for the refractory materials in the steel industry, refractory lining in waste burners. |
