| History and Recent Development of Non-Oriented
Electrical Steel in Kawasaki Steel Atsuhito Honda, Yoshio Obata, Susumu Okamura. |
| Synopsis: Since the first production of cold rolled non-oriented steel strip in 1954, Kawasaki Steel has developed various kinds of electrical steels, and has established mass production techniques, facilities and systems for producing non-oriented electrical steels having not only excellent magnetic properties but also good punchability, weldability, strict gauge accuracy and appropriate mechanical properties. Recently, new products such as 50RM230 of the lowest iron loss, RP series of high permeability, and RMA series of low iron loss, secured after SRA (stress relief annealing), were developed. These are expected to meet customers' requirements from the viewpoint of energy saving and efficiency improvement of motors for home appliances of late years. |
