提高热轧变压器硅钢片的磁性能,除受冶炼化学成份影响外,在很大程度上取决于最后的成品退火工艺。近几年来,我国在硅钢片的退火工艺上,已开始采用真空和氢气作为保护气氛的退火方法,并且取得了一定的效果。本文仅就我厂一年多来,对热轧变压器硅钢片采用氢气退火工艺中的一些问题,提出初步的探讨意见。 Improve the magnetic properties of hot-rolled transformer silicon steel sheet, in addition to smelting chemical composition, largely depends on the final product annealing process. In recent years, our country in the silicon steel annealing process, has begun to use vacuum and hydrogen as a protective atmosphere annealing method, and achieved some results. This article only my plant more than a year, the hot-rolled transformer silicon steel using hydrogen annealing process some of the issues put forward preliminary discussion.
