电力工业的发展与软磁材料的生产有关。在1963年一次磁性材料的学术会议上,英国Wells谈到大型的蒸气发电机,200兆瓦,蒸汽为2350磅/吨吋~2,在1050°F(565℃)温度下工作,需要高质量的钢片。现在电机制造厂又接受了两个375兆瓦,蒸汽为3500磅/吨吋~2,温度1100°F(约595℃)的订货。由于透平发电机采用如氢气冷和静子绕阻用液体冷却等的进展,要求大型的变压器。最近十年硅钢片由热轧改变为冷轧,需要时行新厂的建立与费用甚多的装配。取向硅钢片能用于高磁感,使变压器重量大为减小。制造取向钢片需要连续式退火炉,这些设备只适于产量高的单位。目前对小型马达提出采用含硅1%的硅钢片。制造变
The development of the power industry is related to the production of soft magnetic materials. At a conference on magnetic materials in 1963, Wells talked about large steam generators, 200 MW, and steam at 2350 psi, operating at 1050 ° F (565 ° C), requiring high quality Steel. Now, the motor manufacturer has accepted two orders of 375 MW with steam of 3500 lb / ton-2 and a temperature of 1100 ° F (about 595 ° C). Due to the use of turbogenerators, such as hydrogen cooled stator and stator winding with liquid cooling progress, require large transformers. In the last ten years, silicon steel sheets have been changed from hot rolled to cold rolled, and new plants have to be set up and costly to assemble as needed. Oriented silicon steel can be used for high magnetic induction, the transformer weight is greatly reduced. The production of oriented steel requires a continuous annealing furnace, these devices only suitable for high yield units. Currently proposed for small motors using silicon 1% silicon steel.
