Rolling method for strip and corresponding rolling line
Rolling method for the production of flat products with low productivity, which includes a continuous casting step at a speed between 3.5 m/min and 6 m/min of a thin slab with a thickness between 25 and 50 mm. It also includes a roughing step to reduce the thickness in at least one roughing stand to a value between 6 mm and 40 mm, and suitable for winding, a rapid heating step by means of induction in order to at least restore the temperature lost in the segment downstream of casting and in the roughing step, a winding/unwinding step in a winding/unwinding device with two mandrels. The method also includes a rolling step in a rolling unit that consists of a single reversing stand of the Steckel type to roll the product unwound by the winding/unwinding device.
Reversing rolling mill and operating method for a reversing rolling mill
Operating method for a reversing rolling mill having at least one reversing rolling stand (2) for rolling a rolled metal stock (5), wherein the stock (5) passes the at least one reversing rolling stand (2) in a sequence of alternating direction passes (7) and after each pass, the stock is wound up by a reversing reel (3, 4), wherein only rolling oil, without water as a carrier medium, is applied to the stock (5) by rolling-oil applicator (6), between the at least one reversing rolling stand (2) and the winding-up reel (31, 41).
Shape-correcting and rolling method and shape-correcting device for high-strength steel
There are provided a shape-correcting and rolling method and a shape-correcting device for effectively correcting the shape of high-strength steel. The shape-correcting and rolling method includes: transferring a hot-rolled coil to a pay-off reel after cooling the hot-rolled coil or directly through a hot rolling to skin pass mill direct transfer process; unwinding the coil from the pay-off reel; correcting a shape of a strip unwound from the coil by using a heat pipe roller; and rewinding the strip as a coil.
Rapid discharge forming process for amorphous metal
Embodiments herein relate processes for bulk solidifying amorphous metal alloys by rapid capacitor discharge.
Method and device for cooling a leader or band of a metal strand in a hot-rolling mill
A method and device for cooling a preliminary strip of metal in a hot rolling mill including work rolls by spraying a cooling agent on to the preliminary strip, screening the preliminary strip in an edge area of the strip from influence of the cooling agent, and deflecting the cooling agent in the area of the strip edges of the preliminary strip, wherein the cooling agent is deflected from the strip edges in an area of an inlet guide of a work a work roll.
