The production process mainly includes the following steps: material selection, cutting, straightening, processing thread, twisting, annealing treatment, drawing, surface treatment and testing and packaging.
Specifically, the molybdenum wire is wrapped tightly, smoothed and straightened by mechanical or manual methods, and then the twisted wire hook is rotated for a certain number of turns by mechanical power, and finally the molybdenum twisted wire with twisted twist is made. Molybdenum twisted wire has different specifications such as large twisted wire, small twisted wire and long twisted wire.
Wire cutting molybdenum wire is a kind of consumables made of precious metals such as molybdenum, which has high inter-layer peel strength. This kind of molybdenum wire plays an important role in the wire cutting process. It is used as the electrode wire to continuously move under the high voltage electric field to carry out pulse spark discharge erosion on the workpiece and cut metal forming.
Molybdenum wire ring is a tool that can measure surface roundness and straightness. It uses the elasticity of molybdenum wire to detect surface deviation. By reading the scale on the molybdenum wire ring, the deviation of the measured surface can be judged. Molybdenum wire rings are often used to measure the deviation of the inner diameter of the cylinder block.
Molybdenum rods have high melting point, good thermal conductivity and low thermal expansion properties. At high temperatures, it can resist oxidation and have high strength.
Molybdenum rods and molybdenum rods are manufactured, and different lengths can be provided according to customer needs. In addition, there are three different surface treatments depending on the end use of the molybdenum rod.
CTOMS produces pure molybdenum rods and lanthanum-doped molybdenum rods. Doped lanthanum-molybdenum rods have a smaller cross-section after recrystallization and can maintain ductility at higher temperatures.
High temperature molybdenum rod
High temperature molybdenum rod, also known as molybdenum lanthanum alloy rod, is a kind of metal material with excellent high temperature performance. Its main component is molybdenum, and contains a certain proportion of lanthanum element (usually 0.4~1.2), the rest is the balance except for impurities. High temperature molybdenum rods have high melting point, good thermal conductivity, low thermal expansion and excellent oxidation resistance.
Molybdenum electrode is a transition metal molybdenum as the main raw material of the electrode, English name for molybdenum electrode, molybdenum content of more than 99.95%, with pure metal molybdenum is extremely similar to the physical and chemical properties, the diameter is generally between 20mm-152.4mm, the length can reach 1500mm. It is worth mentioning that there is a big difference between molybdenum electrode and tungsten electrode in terms of shape and use.
