Normalizing process for improving inhibition capability of high-magnetic-induction oriented silicon steel inhibitor

The invention relates to the field of iron and steel smelting, discloses a normalizing process for improving the inhibiting capacity of a high-magnetic-induction oriented silicon steel inhibitor, and aims to solve the problem that the inhibiting capacity of the high-magnetic-induction oriented silicon steel inhibitor in the prior art is low, the normalizing process comprises the following five stages: stage 1, heating to 1100-1150 DEG C, and carrying out heating and heat preservation; stage II, reducing the temperature to 850-900 DEG C, and preserving heat; stage 3, raising the temperature to 940-960 DEG C and preserving heat; stage IV, reducing the temperature to 800-850 DEG C, and preserving heat; stage 5; and rapidly cooling to 100 DEG C or below at a cooling rate of 30-60 DEG C/s. The design purpose of the invention is to utilize the characteristic of high-temperature precipitation of manganese sulfide, disperse fine precipitation of manganese sulfide is realized through rapid cooling, and then part of pr
