The science behind the temper mill involves compression, or rolling, the stainless through what is known as a cold reducing process, temper pass. This increases the density of the steel by reducing its overall thickness by around 1.5% to 2%, consequently, not allowing the steel to expand under pressure.

Modern, efficient cold rolling mills can roll pickled sheets or strips at speeds of up to 4 m/s and tandem mills that are continuously working can produce up to 2.5 million tons of cold rolled steel annually. The advantages of cold rolling. Cold rolled products have the following advantages over hot rolled: greater dimensional accuracy

The 4-high mill is equipped with positive and negative work roll bending in order to influence the shape and the flatness of the strip. Either the work roll or the back-up roll is driven, depending on customer requirements. The diameter of the 4-high work rolls amounts to approximately 1:4 in relation to the barrel length.

Ma et al. found that in the cold tandem rolling and the reversible rolling, or using the advanced universal crown mill with work roll shifting (UCMW) and the taper work roll contour technology, the quarter buckle is likely to occur, and the local modification of the contour can reduce this high-order wave.

The reversing cold rolling mill is the all-rounder among the cold rolling mills: Here, thin strips, thick strips, soft grades, high-strength and ultra-high-strength strips can be rolled in succession on one and the same plant. The RCM is mainly used for low carbon steels, but is also a good solution for modern grades such as silicon steels. ...

A Temper Mill installed in line with a conventional coil leveling line is the perfect solution to the market's demand for this type of material. DELTA's Temper Mill allows our clients to cold reduce the steel, thus affecting a majority of the cross-section and eliminating any spring-back that may result from subsequent processes.
