Problems solved by technology
Amorphous alloy magnetic strips have strict requirements on the preparation conditions, and the cooling rate must reach more than 100,000 degrees Celsius per second. If the cooling efficiency is insufficient or the thickness of the amorphous alloy magnetic strip is too large, it is easy to cause the amorphous alloy magnetic strip to Insufficient cooling rate reduces the amorphous structure inside the alloy magnetic strip, which affects the performance of the alloy magnetic strip; limited by the thickness of the amorphous alloy magnetic strip, some amorphous alloy materials with high magnetic properties are difficult to Preparation of continuous magnetic strips
