1. During the first several rolling passes, fully considering the formability of material and yielding rates to roll as much as possible;
2. Rolling reduction rate of the last process will be controlled within 40%-50% to improve the shape quality and thickness precision;
3. Rolling rates of middle passes shall be almost the same and we need to adopt the highest rolling speed to keep the sheet/coil temperature with in90-120℃;
4. The rolling rates of the last two passes shall be controlled at 40% to adjust the shape;
5. The highest rolling pressure shall not exceed the nominal ones while we have to lower the rolling passes.
