非晶合金铁心介绍

Introduction of amorphous alloy core

（1）、非晶合金在成材过程中急速冷却、卷绕铁心时会产生应力，而非晶合金铁心材料对机械应力非常敏感，无论是张引力还是弯曲应力都会影响其磁性能，为了获得良好的损耗特性，非晶合金铁心成型后必须在一定的磁场条件下进行退火处理。而其退火工艺比较复杂，要求较高。

(1), fast cooling, amorphous alloy in the process of being wound core will produce stress, rather than material of amorphous alloy core is very sensitive to mechanical stress, or whether it is a gravity bending stress will affect the magnetic properties, in order to obtain good loss characteristics, forming an amorphous alloy core must be annealed in a magnetic field under certain conditions. And its annealing process is more complex and requires higher requirements.

（2）、由于非晶合金铁心芯的损耗会随着压力的增大而增加，在对非晶合金铁心进行退火处理的同时，还需要我们在器身结构设计时给予充分考虑，采取合适、有效的措施。

(2) because the loss of amorphous core will increase with the increase of pressure. During the annealing process of amorphous alloy core, we need to give full consideration to the design of the body structure and take appropriate and effective measures.

（3）、非晶合金铁心材料退火之后使材料变的非常脆，易产生碎屑，需要我们在生产过程采取一定的工艺措施。

(3) after annealing of amorphous alloy iron core material, the material becomes very brittle and easy to produce detritus, so we need to take some technical measures in the process of production.

（4）、非晶合金铁心片厚度极薄，仅0.025mm，不到常用硅钢片的1/10；非晶合金铁心叠片系数较低，只有0.86。

(4) the thickness of amorphous alloy core is very thin, only 0.025mm, not 1/10 of the common silicon steel sheet; the superposition coefficient of amorphous alloy core is low, only 0.86.

（5）、非晶合金的饱和磁通密度较低（约1.5T），所以非晶合金铁心的额定磁通密度（1.3—1.4T）比冷轧硅钢片（1.6—1.7T）低。因此，产品设计受到材料的限制。

(5) the saturation magnetic flux density of amorphous alloy is low (about 1.5T), so the rated magnetic flux density of amorphous alloy core is 1.3 to 1.4T, which is lower than that of cold rolled silicon steel sheet (1.6 1.7T). Therefore, the design of the product is limited by the material.
