[0002] Cold rolling is made of hot-rolled coils as raw materials and is rolled below the recrystallization temperature at room temperature. Cold-rolled steel plates are steel plates produced through the cold rolling process, referred to as cold plates. The thickness and width of cold-rolled plates are determined according to the equipment capacity of each factory and market demand. In the subsequent processing of cold-rolled steel plates, cutting equipment is required to cut them into small pieces for processing and use.
