摘要： A method of producing a grain oriented silicon steel sheet is adapted to lower the iron loss. A silicon steel slab, containing about 2.0 to 4.0 weight % of Si and an inhibitor-forming amount of S, or Se, or both, is hot rolled. After the hot rolled steel sheet is annealed when necessary, the steel sheet is cold rolled into a cold rolled steel sheet having a final thickness by performing cold rolling either one time or a plurality of times with intermediate annealing therebetween, the cold rolled steel sheet then being subjected to decarburization, coating of the surface of the steel sheet with an annealing separation agent mainly comprising MgO, secondary recrystallization annealing, and purification annealing. In the cold rolling step, an oxide layer exists on the surface of the steel sheet. Specifically, in the cold rolling step, rolling oil is supplied only at the entrance of the rolling mill used, and an oxide layer having a thickness of about 0.05 to 5 .mu.m is generated. Or, an outer oxide layer of an oxide layer structure generated on the surface of the steel sheet after hot rolling or intermediate annealing, is removed, and an inner oxide layer of a thickness of about 0.05 to 5 .mu.m is maintained on the surface, the resultant steel sheet then being subjected to cold rolling.
摘要翻译：一种生产晶粒取向硅钢片的方法适用于降低铁损。将含有约2.0〜4.0重量％的Si和抑制剂形成量的S或Se或两者的硅钢板热轧。在必要时对热轧钢板进行退火后，通过进行一次或多次冷轧，中间退火，将钢板冷轧成具有最终厚度的冷轧钢板，然后将冷轧钢板用主要包含MgO的退火分离剂，二次再结晶退火和纯化退火对钢板表面进行脱碳，涂覆。在冷轧工序中，在钢板表面存在氧化层。具体而言，在冷轧工序中，仅在所使用的轧机的入口处供给轧制油，生成厚度为0.05〜5μm左右的氧化物层。或者，除去在热轧或中间退火之后在钢板表面产生的氧化物层结构的外部氧化物层，并且在表面上保持约0.05〜5μm的厚度的内部氧化物层，然后将所得的钢板进行冷轧。
