Problems solved by technology

However, the technical equipment is relatively complicated, and it needs to be equipped with devices such as medium and high-frequency electromagnetic field generators. During the drawing process, protective gas needs to be continuously introduced, and the production cost is relatively high.
In addition, due to the extremely fast heating speed of the electromagnetic induction method, a sensitive temperature feedback device is required, and ordinary temperature measurement methods such as Hall element temperature measurement and thermocouple temperature measurement are difficult to meet its requirements
