Digital steel plate
There are traditional wide and thick plate rolling mills and hot continuous rolling+heat treatment production methods for wide and thick plates, with higher requirements for flatness and convexity. PDA supports 5000 plate shape measurement curves horizontally, as shown in the above figure, which can be locally enlarged. The complete set of equipment for the medium and thick plate production line mainly includes: vertical roller rolling mill, four roller rolling mill, straightening machine, fixed length shear, double-sided shear and splitting shear, fast cooling speed device, etc. The basic production process is as follows: continuous casting billet → feeding → heating furnace → descaling → (rough rolling) → precision rolling (controlled rolling) → (rapid cooling) → hot straightening → cooling bed → inspection and grinding → cutting head, tail, sample, length and edge → surface inspection and cleaning → marking → collection → warehousing → shipment.
