Abstract

Abstract: Decarburization annealing process test was carried out on high magnetic induction oriented silicon steel 27QG090 in the laboratory by means of independently developed heat treatment test device. The microstructure and macroscopic texture of the specimens after decarburization annealing were analyzed by means of Zeiss microscope and X-ray diffractometer. The results show that the microstructure of the 27QG090 high magnetic induction oriented silicon steel after decarburization annealing is ferrite and its average grain size is 30-40 μm. The main types of macroscopic textures are α texture and α^* texture ({114}〈481〉、{113}〈361〉), together with some weak Gaussian texture{110}〈001〉. The best process selected through laboratory research is decarburization annealing at 850 ℃ for 7 min. The macroscopic texture of the industrial production line after decarburization annealing is the same as that of the decarburization annealed one in laboratory. When the average grain size is about 30 μm after decarburization annealing, the lowest iron loss is 0.80 W/kg, and the magnetic induction intensity reach 1.93 T.
