Production Flow of cold rolled steel coil
Brief introduction of main equipment of cold rolled steel coil
(1) Pickling lines
The Raw material is hot rolled steel coil (HR), HR coil weight is always more than 20T. The thickness of HR is always more than 2.5mm thickness.
The purpose of the pickling lines is to remove the metal surface oxide.
(2) Cold rolling mill
The cold rolling mill is to roll the coil to required thin thickness, such as roll from 3.5mm to 0.5mm, 1.0mm.
Five stand tandem CRM
(2) Annealing Line
There are two different kinds anneal:
A: Continuous annealing Line: thickness: 0.4mm to 2.0mm
B: Annealing Furnace: thickness: 0.3mm to 2.0mm
