The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.

The process of plastically deforming metal by passing it between rolls. • Rolling is the most widely used forming process, which provides high production and close control of final product. • The metal is subjected to high compressive stresses as a result of the friction between the rolls and the metal surface. 3.

Raw Materials As we meet the increasing demand for more raw material sizes, the flat wire rolling mill operation in our plant continues to grow. Years ago, Smalley began a vertical integration that evolved into the production of hundreds of material cross-sections in a wide variety of alloys. In most cases, we can deliver retaining rings, snap rings and wave springs to …

However, in hot-rolling mills, water used for descaling and cooling steel (process water) and water used for cooling rolls and bearings (cooling water) were reported together. Inasmuch as the steel indus­ try generally considers all water used in rolling mills as cooling water, it is reported as such in this report.

9 17 Rolling Mills Equipment is massive and expensive Rolling mill configurations: – Two-high: two opposing rolls – Three-high: work passes through rolls in both directions – Four-high: backing rolls support smaller work rolls – Cluster mill: multiple backing rolls on smaller rolls – Tandem rolling mill: sequence of two-high mills 18 Various configurations of rolling mills: (a) 2 ...

rolling at one point in their manufacture. Metal rolling is often the first step in creating raw metal forms. The ingotor continuous castingis hot rolled into a bloom or a slab, these are the basic structures for the creation of a wide range of manufactured Blooms typically have a square cross section of greater than 6x6 inches.

Wherever you look, seamless steel tubes are an integral part of modern life. Today, the oil and gas industry, the construction and mechanical engineering industries, and automotive manufacturers demand ever better tubes made of higher steel grades, with closer tolerances and new dimensions.

In the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change in its cross-sectional area.. The types of rolls used in rolling mills are depended upon the shape, size and the gap between the rolls and their contour. Because of workability and limitations in …
