Katika tasnia ya karatasi ya alumini, kuna uainishaji wengi wa karatasi za alumini, ambayo inaweza kugawanywa katika cold rolling aluminum plate na hot rolling aluminum plate according to the different production processes. Tofauti kati ya karatasi ya alumini iliyovingirishwa kwa baridi na karatasi ya alumini iliyovingirwa moto ni kama ifuatavyo.
1, mchakato wa uzalishaji ni tofauti: cold-rolled is a casting machine processing into casting roll (8mm unene) after cold rolling machine processing, and hot-rolled is an aluminum ingot (400-500mm unene) heating, in high temperature by the hot rolling mill rolling;
2, the raw material supply is different: the difference between the two in the billet supply is not the same, hot-rolled billet is cast aluminum ingot - heating - rolled into a volume for cold rolling, cold-rolled billet is cast rolled volume - cold rolling rolling;
3, different performance: hot-rolled aluminum surface quality, while mechanical properties and ductility, athari ya oxidation ni nzuri, while processing aluminum discs are generally processed from the aluminum plate, naturally also affected by the performance of the aluminum plate;
4, the use of different: cold-rolled aluminum plate is mostly used in the mold class, aluminum plate hot rolling suitable for stamping and drawing aspects.
