Process: hot rolled steel plate is called hot plate and cold rolled steel plate is called cold plate.
Appearance: hot plate is rough blue and black, cold plate is smooth and silvery white
Mechanical properties: hot plate tensile strength and elongation are not as good as cold plate
Price: hot plate is cheap and cold plate is expensive
1. Characteristics of the heating plate: low surface toughness and smoothness, low price.
2. Cold plate characteristics: good stretchability and toughness, but the price is more expensive.
1. Hot plate production process: heated by bai in a mobile heating furnace, high pressure water softening enters du rough laminator, and rough rolled material enters finishing laminator through head and glue, and then lamination is performed by computer controlled. After finishing winding, it is wound by laminar flow cooling (computer controlled cooling speed) and wound to form straight hair spirals.
2. Cold plate production process: Ordinary carbon structural steel hot rolled steel strips are cold rolled to obtain steel plates with a thickness of less than 4mm.
