Plate and strip rolling surface processing, there are three basic they are through the village of plate and belt production process.
不。
1: after hot rolling, annealing, pickling and descaling.
After processing of the surface of the steel plate is a dull surface, a bit rough.
不。
The 2 d: N0.
1 good surface finish and dull surface.
After cold rolling, annealing, descaling, finally with light hair side roller mill.
不。
2 b: this is the most commonly used in the application of construction, in addition to using polishing roll after annealing and descaling finally a mild cold rolling, the other process is the same as 2 d, slightly light-emitting surface, polishing processing.
不。
2 b bright annealing: this is a reflective surface, after polishing roller rolling and final annealing in a controlled atmosphere.
Bright annealing still maintain its reflecting surface, and does not produce scale.
As bright annealing does not occur in the process of oxidation reaction, therefore, do not need to pickling and passivation.
