The Main Processing Method Of Rare Earth Tungsten Electrode

Apr 13, 2020

The main processing method of rare earth tungsten electrode is powder metallurgy process. Sintering is the most important process in the production of rare earth tungsten electrode, which plays a decisive role in the performance of rare earth tungsten electrode.

In tungsten electrode industry, vertical sintering is mainly used. Due to its sintering process characteristics, the temperature gradient of tungsten slab is large and the consistency of sintering density is poor. High consumption of electricity and hydrogen, high cost of sintering, and the vertical melt strip should be cut off the chuck at both ends (about 4%), the rate of finished products is reduced and other shortcomings.

The temperature of intermediate frequency induction sintering is lower than that of vertical sintering, and the temperature field is uniform, so the structure and properties of the products can be improved. And high yield, low energy consumption, high economic benefits.
