Brief description of the process

The qualified billet was transported to rolling plant by roller bed, and was heated by the pusher-type furnace to 1050 ~ 1150 ℃, pushed out by discharging machine. Then the billet was fed to roughing rolling millφ550 group by furnace delivery table, after roll 5 passes, cutting by 1# flying shear, then enter into intermediate rolling mill group φ420 mm×8, after sheared by 2# flying shear, then enter into the φ320 mm intermediate mill group(6 stands), after water treatment，enter into conveyor roller bed, and then sheared by dividing shear, enter into rolling piece conveyor roller bed, then enter into cooling bed, cutting by cut-to-length shear, then banded, then delivery or enter into storage. The production process is as follows:

The Composition of rolling mills

The whole production line will be equipped with 20 rolling passes all together, among which, φ550mm 41 rougher mill is the shuttle rolling type mill, and after taking off ends and the semi-finished materials will enter other 20 intermediate(φ420mm×6+φ320mm×6 +φ285×4) finishing rolling mills, which are all the continuous rolling type (DC controlled).
