Super Core 超级铁芯 

Super Core is manufactured using an innovative process that is completely different from that for conventional silicon steel sheets. These are the highest grade, non-oriented magnetic steel sheets available.
Conventional silicon steel sheets have a Si (silicon) content of 3.5% or less. It has long been known that the magnetic characteristics of a silicon steel sheet improve as the Si content increases, peaking at 6.5%.
However, it has been impractical to produce thin steel sheets with a Si content of over 3.5% because the steel tends to harden and become brittle. In 1993 JFE Steel solved this production problem through the adoption of a process called the CVD process, and successfully introduced the first 6.5% Si steel sheets (JNEX-Core) to the world. In order to meet new demands, this technology has continued to be developed, leading to the commercial production of gradient high-silicon steel sheets with superior high-frequency characteristics (JNHF-Core).
以往的硅钢片最多添加3.5%的Si(硅)。众所周知,若增加硅含量,其磁性能会得到相应提高,当Si的添加量达到6.5%时,磁性最高。但Si含量超过3.5%时,会使钢变硬变脆,从而无法轧制成薄钢板。
1993年,JFE钢铁采用CVD工艺法,解决了这个制造难题。 6.5%的硅钢片(JNEX铁芯)的工业化也首次在世界上取得了成功。 此外,为了满足新的需求,进一步发展此技术,高频率特性的卓越梯度高硅钢片(JNHF铁芯)也实现了商业化批量生产。

充分发挥此特点,可用于屏蔽用途或电流转换器等。
Stable Quality
质量稳定
The high-temperature processing provides thermal stability. Since there is minimal deterioration of the properties due to machining, so stress-relieving anneals are not required.
由于作了高温处理,所以具备热稳定性。
且加工导致的特性劣化程度低,
所以不需要做消除应力退火处理。
Non-oriented
无取向性
There is virtually no difference in the characteristics between the rolling direction (Ldirection) and the transverse (C-direction). Therefore, this can be used in a wide range of applications, from stationary machines to rolling machines.
产品的轧制方向(L方向)和宽度方向(C方向)的特性几乎没有差别。
因此,可广泛应用于从静止器到旋转机等各种领域。
