Wire cutting you must have heard of it, it belongs to the electrical machining of machine tools, mainly used in the processing of mold, complex shape or micro structure and other products, the tool used in the cutting process is a thin line, relying on the discharge of several thousand degrees Celsius high temperature to melt metal. When wire cutting processing, the hair-like fine line is a kind of consumable material made by molybdenum and other precious metals. Wire cutting also divides fast moving wire (with molybdenum wire) and slow moving wire (with copper wire). Molybdenum wire can not only process all kinds of metals, but also widely used in winding core wire, lead wire, heating element, etc. Molybdenum wire has high precision requirements, low wire breaking rate, fast processing speed, and can achieve stable and long-term continuous processing. Molybdenum wire is the main component of molybdenum (Mo), the content of more than 99%, molybdenum in nature mainly exists in molybdenite (MoS2). Molybdenite in very long period of time are treated as graphite, this soft gray mineral, in the 18th century by schere molybdenite itself is not a kind of graphite, but some metal ore, he is also trying to restore the pure metal molybdenum, but did not reach the required temperature of the furnace, by sea gill's success after years of produce the silver metal molybdenum.
Ammonium paramolybdate or Calcined MoO3 is the material for making molybdenum powder. In industrial production, pure ammonium paramolybdate can be directly restored to molybdenum powder in the furnace, or it can be calcined into MoO3 at 550 ~ 650℃, and then restored to molybdenum powder. In the production of molybdenum products by powder metallurgy, high purity molybdenum powder, low oxygen content, fine particle size and uniform powder are required. Molybdenum powder is produced by the secondary restoration of MoO3 or ammonium paramolybdate to MoO2 in a round tube or muff tube electric furnace, and the second restoration is the restoration of MoO2 to molybdenum powder at a higher temperature. In order to ensure the quality of molybdenum powder, in addition to the recovery temperature, the flow rate and humidity, the thickness and pushing speed of the material layer, and the particle size of the material are all factors affecting the particle size of molybdenum powder. Generally, H2 flow is large and dew point is low, and the powder is fine, whereas the powder is coarse. Therefore, it is necessary to strictly control these elements in the production process to obtain qualified powder.
