Ieu mangrupakeun karakteristik kotak aluminium rolling yén simpangan ketebalan hese ngadalikeun. Beda ketebalan tina 3% teu hese ngadalikeun dina produksi piring jeung strip, tapi leuwih hese ngadalikeun dina produksi aluminium foil.
Salaku ketebalan tina kotak aluminium janten thinner, kaayaan mikro na tiasa mangaruhanana, sapertos suhu, pilem minyak, 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.
Ku kituna, 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.
