Hot rolled strip

 

Strip is widely used in the production of welded steel pipe, cold-formed steel billet, manufacturing bicycle frames, rims, clamps, washers, springs, saw blades, metal products and blades

Cold-rolled strip steel production process is generally: pickling → rolling → process lubrication → annealing → smoothing → cutting → packaging.

 

Cold-rolled strip process: Pickling - Rolling - Annealing - Rolling Synchronous lubrication - Antirust oil - Flat length - Polishing - Packaging

 

Hot-rolled strip process: Heating furnace - Phosphorus removal machine - Roughing mill - Phosphorus removal machine - Finishing mill - Surface quality inspection instrument - Layer cold - Coiler - Balers - Pen Machine - roll library slab

 

Hot-rolled strip production process: First, the temperature in the heating furnace to the desired rolling temperature, and then through the roller into the roughing phosphorus removal of the slab produced by the oxide scale, and then into the rough rolling mill The strip width and thickness of the rolling, and then by the roller conveyor to the finishing mill dephosphorization of the surface of the strip produced by the oxide scale, into the finishing rolling unit of the strip thickness and width of more For the precision rolling, strip by the roller through the cold on the surface temperature before the coiling of the strict control before entering the coiler to become the last bunch of coil, spray into the coil storage package. .
