The importance of choosing the right raw material for wire-cutting molybdenum wire

Wire cutting molybdenum wire is the main deep processing product of molybdenum metal, which has a wide range of applications in metal cutting. In terms of quality, the current domestic market wire cutting molybdenum wire product quality is mixed, can ensure stable product quality, excellent performance of the production enterprises are not many, which brings confusion to the wire cutting molybdenum wire market.

Wire cutting molybdenum wire processing pulling process is relatively long, to commonly used φ0.18mm oil-doped high temperature wire cutting molybdenum wire production, for example, from 17mm molybdenum rods to the finished wire cutting molybdenum wire needs to go through the pulling system of about 40 times. Because the process is long, so there are many intermediate factors that affect the quality of wire-cut molybdenum wire. When the finished molybdenum wire in the drawing process or wire cutting finished quality problems, if you can not start from some of the key influencing factors, it is often difficult to accurately find out where the problem lies. So it is necessary to target from certain key points to start, strengthen process control, to avoid the pulling process is not smooth and product quality problems.

According to the summary of the production practice, the important control of the key links are: the nature of raw materials, tandem spin forging process and intermediate annealing process.

Selection of suitable wire cutting molybdenum wire raw materials is the basis for the production of high-quality wire cutting molybdenum wire, different types and different manufacturers of raw materials are more different. The trend is that rolled rods, which are smoother in the drawing process, less labor-intensive, more consistent and more efficient, have a clear advantage as a raw material for WEDM wires. Controlling the furnace temperature of the tandem rotary forging is a necessary condition for the production of high-performance WEDM wires. As a wire-cutting molybdenum company, you need to determine this process parameter according to your own reality. Molybdenum wire intermediate annealing is the production of high-performance wire cutting key link. Producers must combine their own annealing furnace and intermediate material specifications to accurately determine the annealing time and charging volume parameters, fine determination of the intermediate material annealing temperature parameters.
