A five-pass Steckel mill rolling was physically simulated using a torsion testing machine, and dynamically formed, and retransformed ferrite were quantified. The results can be used to assess and estimate the amount of DT ferrite after each pass during the hot rolling of a X70 steel grade for more control of the manufacturing process and ...

Plate Mills are quite literally the most powerful metal-working tools on earth, but they are precision tools too. Precise control of dimensions is critical, and so is imparting mechanical properties to the rolled product. The plate rolling process affords great flexibility in terms of how mechanical properties are achieved, through a ...

The concept of Plate/Steckel mills provides a middle ground in plate rolling by producing discreet plate (up to 50mm) and coil plate (4.5 to 25mm) in one line. Pure Steckel Mills are also beginning to emerge as major contenders where a low cost start in the market is sort by an investor. These produces both carbon steel, stainless
