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 ...

A Steckel mill is a type of tandem rolling mill. This means that the mill is composed of a series of different, connected rollers that the metal passes through. Instead of having to pass the metal through one set of rollers several times, the same finish can be achieved with just one pass through a Steckel mill, though multiple passes through ...

Steckel mill Last updated January 16, 2020. A Steckel mill, also known as a reversible finishing mill, [citation needed] is similar to a reversing rolling mill except two coilers are used to feed the material through the mill. One coiler is on the entrance side and the other on the exit side. The coilers pull the material through the mill, therefore the process is more similar to drawing than ...

Abstract. The microstructural evolution in AISI304 austenitic stainless steel during Steckel mill rolling has been investigated. Particular emphasis is placed on the microstructural behaviour of the strip ends relative to the strip bulk. Good correlation between the development of hard ends that arise in the final strip and strip temperature ...

The development of Steckel mills is reviewed, along with their advantages and disadvantages. In recent years, mills with heated coiling units have been widely adopted for the production of an extensive range of hot-rolled sheet and strip. New mechanical and organizational approaches are considered. Steckel mills are found to be expedient for use in mini mills and in casting and rolling systems.
