Based on the hardness and microstructure of the primary cold-rolled sheet of oriented silicon steel 27Q110 recrystallization temperature annealing test

the optimal annealing temperature of decarburization annealing (primary recrystallization) of oriented silicon is determined to be 850 °C. The microstructure and texture of the oriented silicon steel 27Q110 produced at cold rolling works after decarburization annealing are detected and analyzed. Be results show that the optimum annealing temperature of decarburization of oriented silicon steel 27Q110 is 850°C

and the main γ texture is the strongest at {111}<112> .
