摘要/Abstract

摘要： 研究了高温退火二次升温阶段的退火温度及露点温度对HiB取向硅钢表面硅酸镁底层的影响。结果表明,高温退火二次升温阶段的最终温度在1100~1170 ℃范围内时生成的硅酸镁底层质量较好;当退火气氛中存在水蒸气时,会降低硅酸镁底层的质量,且水蒸气含量越高,即露点温度越高,硅酸镁底层的厚度越薄,质量越差。

Abstract: Effects of annealing temperature and dew point temperature in the secondary heating stage of high temperature annealing process on formation of magnesium silicate on surface of the HiB oriented silicon steel were studied. The results show that the quality of the forsterite film is better when the final temperature of the secondary heating stage of high temperature annealing is in the range of 1100-1170 ℃, but when water vapor remains in the annealing atmosphere during the secondary heating stage of the high temperature annealing, the quality of the forsterite film on the surface of the HiB oriented silicon steel is poor, and the higher the water vapor content is (meaning the higher the dew point temperature is), the thinner the thickness of the forsterite film, and the worse the quality of the forsterite film is.

Key words: forsterite film, HiB steel, high temperature annealing process, annealing parameter
