Abstract

Abstract:

The mechanical tensile test, microstructure observation and texture analysis for 50W600 non oriented silicon steel produced by two different hot rolling processes (CSP and 2250 mm semi continuous rolling) were carried out to study the difference of microstructure and comprehensive properties between the two processes. The results show that the microstructure of the non oriented silicon steel 50W600 produced by CSP process is more uniform, the average grain size is larger than that of produced by 2250 mm hot rolling process, and the mechanical properties of the hot rolled plate are slightly lower. The unfavorable texture of 50W600 non-oriented silicon steel produced by short-process CSP after acid rolling and continuous annealing is relatively less, and the magnetic properties are better than that of produced by 2250 mm hot rolling process.

Key words: non-oriented silicon steel 50W600, CSP short process, 2250 mm rolling process, microstructure, magnetic properties
