Description
加工ラインの前記のタイプの溶融めっきに続いて、指定ストリップEN10111−DD11を生産する冷間減厚のための熱間圧延された軟鋼が、ほぼ6.5%の制御された減厚を受けた。この加工プロセスでは、降伏点(イールドポイント)(Rp0.2)が80N/mm2まで増加し、引張強度(Rm)が30N/mm2まで増加し、それに対してスチールストリップの伸張(A80,一様な伸張)は10%減少、すなわち30%から20%に減少した。
実施例1が繰り返されたが、制御された減厚に代えて1%のテンパーパス圧延が実行された。実施例1のように、ホットストリップコイルのストリップ長さに沿う厚さが記録された。
