METHOD OF COLD-ROLLING FOR PRODUCING GRAIN-ORIENTED ELECTRICAL STEEL SHEET HAVING SPECIAL QUALITIES |
| 摘要 |
<p>A cold rolling method for producing a high magnetic flux density grain oriented electrical steel sheet or strip having remarkably excellent B8 characteristics, comprising subjecting a hot rolled steel sheet or strip a combination of heavy cold rolling with annealing during which the steel sheet or strip is held at a temperature between 100 DEG and 350 DEG C at an interim sheet thickness stage during the heavy cold rolling.</p> |
