Through the process of cold rolled steel reduction Alliance Steel has the ability on site to reduce the gauge down on your material to hold +/-.0015. Cold reduction is a process of re-working material through a series of work rolls to create a uniform gauge throughout the material.
Cold rolling is used to reduce the temperature of the material being worked with while also increase how hard and strong the material gets during the rolling mill process. During this process, the overall finish and granule structure of the material is is made more pure and workable.
In fact, the combination of cold reduction and annealing lead to a refinement of the steel that provides very desirable and unique forming properties for subsequent use by the customer. The hot-rolled, pickled coils incoming to the cold reduction mill have to have excellent quality attributes.

Feb 14, 2019· It consists of a two-stand UCM and is designed to perform double-cold reduction as well as one-stand temper rolling. In the DCR process, the annealed strip, after reduction in a tandem cold mill, is reduce rolled on the No. 1 stand and temper rolled on the No. 2 stand. This process imparts the strip with its prescribed mechanical strength.

A reversing, single-stand, cold reduction mill can be considered similar to the first stand of a tandem mill. Without instrumental control a great deal of skill is required to achieve uniform lateral and longitudinal thickness using a combination of screw-down on the reducing rollers and tension between the reducing rollers and the wind-on reel.
That explains why we design our cold rolling mills to be just as versatile. What's important to you are not only high flexibility and product quality, but also sustained, cost-effective operation of your plants. Opting for our efficient plant designs means you can rely on achieving the precise strip reduction and high surface qualities you want.

Rolled Steel Products Offers Over 70 Years of Family Tradition. Rolled Steel Products Corp., Los Angeles, was founded in 1951.It was purchased in 1973 by Robert Alperson (retired), Rolled Steel's majority owner and Chairman.It has been located at its present site since 1980.
Cold-roll steel sheet. After hot-rolled sheet is pickled, leveled, and edge-trimmed, our cold-rolling mill is capable of reducing the steel's thickness to as thin as 0.013 inches and as thick as .085 inches. Coated steel sheet. We galvanize hot-roll and cold …
A temper mill is a finishing facility that processes steel in the form of sheet and plate in order to give it added strength and uniform flatness to the surface. The metal forming method at a temper mill involves rolling the sheets of steel through what is known as a cold reducing process or temper pass. This increases the density of the steel ...
The Yoder W-15-S Cold Reducing Tube Mill System welds a tube up to 1.25″ (31.8 mm) diameter and can produce finished diameter down to 3/16″ (4.76 mm) diameter.
