Iron Alloy Ferrotungsten

Ferromolybdenum, an amorphous metal additive in the production process, has several excellent properties that are transferred to new alloys. One of the main benefits of ferromolybdenum alloy is its hardenability, which makes the steel extremely weldable, and ferromolybdenum is one of the top 5 high melting point metals in the country. In addition, adding alloys to ferromolybdenum can improve corrosion resistance. The characteristics of ferromolybdenum make it an additional protective film on...

Ferro-tungsten iron alloy series (tungsten content: 70%-80%) is an alloy composed of tungsten and iron, which is used as an alloy additive for steelmaking. Commonly used ferrotungsten contains 70% tungsten and 80% tungsten. Ferrotungsten is prepared from wolframite by carbon reduction in an electric furnace. Mainly used as alloying element additive for tungsten-containing alloy steel (such as high-speed steel). There are three varieties of ferrotungsten produced in my country, including W701,...

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, a small (100-500 kVA) single-phase electric arc furnace was generally used for agglomeration smelting. Later, a three-phase electric furnace was used, and the iron extraction method was developed. There are a large number of tungsten ore in Jiangxi, Hunan and Guangdong in China, and the reserves...

Tungsten is a silver-gray metal. The atomic weight is 183.85. Electronic structure 4f145d46s2. Density (20°C) 19.3g/cm3. Melting point 3400 ℃. Boiling point 5555℃. Tungsten forms solid solution with iron and two intermetallic compounds Fe2W and Fe3W2 or Fe7W6, but both are unstable at high temperature. The melting temperature of ferrotungsten containing W75% to 85% 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 alloys mainly composed of tungsten and iron. It also contains impurities such as manganese, silicon, carbon, phosphorus, sulfur, copper, and tin, and is an alloying agent for steelmaking. According to the different tungsten content, ferrotungsten is divided into: FeW75 (including W70%～80%, C≤0.20%, P≤0.04%, S≤0.08%, Si≤0.5%, Mn≤0.25%) and FeW80 (including W75.0%～85.0%, C≤0.20%, P≤0.04%, S≤0.08%, Si≤0.7% and Mn≤0.25%).

In addition to certain requirements for the impurity content of tungsten powder, the oxygen content should be controlled within a certain range. The particle size of commonly used tungsten powder is generally 2-10 μm in Fisher’s average particle size. The tungsten powder is in the shape of polygonal particles. In addition, the specific surface, bulk density and tap density of tungsten powder also vary within a certain range. The performance of tungsten powder has a direct impact on the...

Tungsten bars include tungsten rods, tungsten steel rods, sintered tungsten rods, mainly used for forging into material components, knives and warheads, light bulb tungsten wires, electrical contacts and thermal conductors, crankshafts and cylinder tungsten wire barrels, heat-resistant steel Various ingredients. Doped tungsten strips are used to produce filaments or tube filaments, which guarantee a significant resistance to high temperatures. Pure tungsten is a natural metal mined from the...

Tungsten powder is the main raw material for processing powder metallurgy tungsten products and tungsten alloys. Pure tungsten powder can be made into wire, rod, tube, plate and other processed materials and certain shaped products. Tungsten powder mixed with other metal powders can be made into various tungsten alloys, such as tungsten-molybdenum alloy, tungsten-rhenium alloy, tungsten-copper alloy and high-density tungsten alloy. Another important application of tungsten powder is to make...
