Abstract
The paper studies the influence of CO2 laser continuous-wave radiation on domain structure of grains of anisotropic electrical-sheet steel having ideal Goss orientation. Fragmentation of 180$DEG domains under laser beam action has been experimentally revealed. It has been shown that high-speed processing of the surface of anisotropic electrical-sheet steel with continuous-wave laser radiation makes it possible to improve the domain structure and to reduce the losses by magnetic reversal P17/50 without substantial lowering of magnetic induction B100. To carry out the technological process, an automated laser technological system (ALTS) has been developed and produced for processing iron circuit plates of 400x1200 mm size with speeds up to 100 m/s.
