板厚偏差の制御が難しいのがアルミ箱圧延の特性です. 厚みの違いは 3% プレートとストリップの製造における制御は難しくありません, しかし、アルミ箔の製造では制御がより困難です。.
アルミボックスの厚みが薄くなるにつれて, 微条件が影響する可能性があります, 温度など, 油膜, and oil and gas concentration. A roll of aluminum foil can be rolled up to hundreds of thousands of meters, and the rolling time is as long as about 10 hours, and the error of thickness measurement is easy to form with time.
The only way to adjust the thickness of aluminum foil is tension and speed.
These factors have caused difficulties in thickness control of aluminum foil rolling.
したがって, to truly control the thickness difference of the aluminum box within 3%, many conditions are needed to ensure: use the aluminum foil blank of the qualified thickness; adjust and control the reduction and roll shape during rolling, and the roll is ground according to the specified parameters ; Stabilize the rolling process; frequently measure the thickness of the aluminum box during the rolling process, so as not to be undetected when the side thickness system fails.
