Tandem Rolling Process :: Total Materia Article

The processing of steel in cold rolling mills differs considerably from the production in hot rolling mills. The raw material is first descaled (usually pickled, sometimes shot blasted and pickled), then cold rolled and heat treated. Further treatment .

Cascade Steel

The steel manufacturing process at our McMinnville, OR facility begins when ferrous scrap metal arrives by rail car or truck and is unloaded by large overhead cranes. Scrap metal is loaded into a "charge bucket" and brought into the melt shop where it will go through our twostep melting process. Continue to next page Return to about us page

TMT Steel bar Manufacturing Process | Shyam Steel

Now molten steel from EAF (Electric Arc Furnace) is transferred to a ladle and it transferred to the continuous casting machine. Liquid steel flows out of the ladle into the casting ladle and then into water cooled mold. Solidifiion begins in the mold. Continuous Billets coming out from the CCM is sized according to the length required.

Rolling Mill

Rolling is a bulk deformation process in which the thickness of the work is reduced by compressive forces exerted by two opposing rolls. The rolls rotate to pull and simultaneously squeeze the work between them. 3 Introduction to Rolling The basic process shown in the previous figure is Flat Rolling, used to reduce the thickness of a

Glossary of Steel Industry Terms

Using hydraulic roll force systems, steelmakers have the ability to control precisely their steel sheet's gauge (thickness) while it is traveling at more than 50 miles per hour through the cold mill. Using feedback or feedforward systems, a computer's gap sensor adjusts the distance between the reduction rolls of the mill 50–60 times per second.

Steckel mill

The Steckel mill allows the rolling of a large slab by providing heated reels on both sides of the mill to store the increased length produced during rolling. These drums allow for additional heat retention and thermal consistency in the rolled piece, which in turn produces improved uniformity throughout the rolled product.
