ZhenAn Ferro Molybdenum
Ferromolybdenum can be used in any smelting process, adding molybdenum to all types of steel, and is available in a variety of sizes for addition to furnaces or ladles. If used correctly, the recovery rate should be essentially 100%. For optimal recovery from ladle addition, ferromolybdenum should be added after the molten metal covers the bottom of the ladle but before it is three-quarters full.
Ferromolybdenum Alloy
Ferromolybdenum is mainly used in:
1.Alloy steel
It consumes the largest amount of molybdenum, accounting for 44% of the world's total molybdenum consumption and more than half of the amount of molybdenum added to steel. Among them, structural steel (or general molybdenum steel) contains about 0.1%~0.2% of molybdenum and is widely used in skyscrapers. , bridges and other large steel components, it can improve the hardness, strength and toughness of steel and extend the life of these large facilities. Molybdenum steel containing 0.3% molybdenum is often used in load-bearing parts and transmission parts in transportation and automotive manufacturing.
2.Stainless steel
It accounts for about 22% of the total molybdenum consumption, and the usual amount of molybdenum added is 4% to 5%. It is often used in places to prevent erosion and corrosion. Such as petroleum refining, gas wells and severely corroded places in oil wells, aircraft engines, marine equipment, chemical equipment, etc.

3. High speed steel and tool steel
It accounts for approximately 8% of total molybdenum consumption. High-speed steel usually contains 3.75%~9.5% molybdenum, with an average of 4.8%, and metals such as tungsten, vanadium, and chromium are often added at the same time. 90% of the high-speed steel currently used in the world contains molybdenum. About 6,000 tons of molybdenum are used in the production of high-speed steel around the world every year. The molybdenum content of tool steel is usually 0.6%~2.95%, and the molybdenum used in tool steel around the world is 2000~2500t every year.
4. Cast iron and rolls
Their consumption accounts for 6% of the total molybdenum consumption. When 0.3%~1.0% molybdenum is added to cast iron, the tensile, bending and fatigue resistance will be greatly improved, and the uniformity of the casting structure will also be improved. This is especially important for large castings, which are widely used in automobile manufacturing. , pressure pipes and molds, etc.
