Shearing Process and Shears. Shearing is a simple process used for the cutting of metals. It is basically a metal fabrication process and is being used in rolling mills at several places for hot as well as for cold cutting of the steel material. Shears can be used to cut steel and other materials of any size or shape.

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 hotrolled 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.

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 ...

21, 39, 40]. In Steckel mill lines, during the hot rolling process, the strips are driven by the roller table in the rolling direction. However, the rolling procedure is susceptible to impel the strips perpendicularly to this direction, which could induce misalignment. For instance, the unaligned strips are prone to collide Aline de Faria Lemos
