退火是矽钢片生产过程中十分关键的一个工艺环节,实践证明,退火工艺的执行情况直接影响到矽钢片的电磁性能(牌号)和翘曲度质量。上海矽钢片厂是利用电热罩式炉来进行退火生产的,退火炉的结构如图(1)所示
Annealing is a key process in the production of silicon steel. Practice has proved that the implementation of the annealing process directly affects the electromagnetic performance (grade) and the warpage quality of the silicon steel. Shanghai silicon steel sheet plant is the use of electric hood furnace for annealing production, annealing furnace structure shown in Figure (1) below
