Ferrotungsten is smelted in an electric furnace. Due to its high melting point, it cannot be released in liquid form, so it is produced by the agglomeration method or the iron extraction method. Before the 1930s, small (100-500 kVA) single-phase electric arc furnaces were generally used for agglomeration smelting. Later, three-phase electric furnaces were switched to and the iron extraction method was developed.
Tungsten is a silver-gray metal. The atomic weight is 183.85. Electronic structure 4f145d46s2. Density (20℃) 19.3g/cm3. Melting point 3400℃. Boiling point 5555℃. Tungsten forms a solid solution with iron and two intermetallic compounds Fe2W and Fe3W2 or Fe7W6, but they are unstable at high temperatures. The melting temperature of ferrotungsten containing 75%~85% W is higher than 2500°C, so it cannot be discharged from the furnace and can only be produced by the accumulation method or the iron extraction method. The density of industrial ferrotungsten is about 15.3g/cm.
