• Packaging: Bag/Drum
• Supply Ability: 8000kg
• Certificate: ISO9001

Iron tungsten is smelted by electric furnace. Due to its high melting point, it cannot be released in liquid state, so it is produced by agglomeration method or iron extraction method. Before the 1930s, small (100-500 kVA) single-phase electric arc furnaces were generally used for agglomeration smelting. Later,...

Tungsten is a non-ferrous metal and an important strategic metal. Tungsten ore was called "heavy stone" in ancient times. In 1781, the Swedish chemist Karl William Scheler discovered scheelite, and extracted a new element acid, tungstic acid. Tungsten powder was obtained by reducing tungsten trioxide with carbon for...
