They are used to roll steel in the rolling mill and their performance depend on many factors which include the materials used and the loads to which they are subjected to during service. The roll design is influenced by the limitations applied by the rolling load, the roll strength and the torque available for rolling.

So far, you are probably feeling that, in dealing with mild steels, cold rolled steel is clearly the better stuff to have if you can afford it. Well, yes, usually, but---- since the hot rolled steel IS rolled while hot, it has a chance to normalize after the last rollers, so it is pretty much stress free when you get it.

The hot-rolled sheet steel is normally cleaned or pickled in a bath of sulphuric or hydrochloric acid to remove surface oxide (scale) formed during hot rolling. A modern pickler operates continuously. When one coil of steel is almost cleaned, its end is sheared square and welded to the start of a new coil. In the pickler, a temper mill helps ...
Cold rolled stainless steel profiles and special shapes find use in various applications. These include mechanical engineering and construction as well as aesthetic applications.

As for width, it can roll anything from 900 to 1,950 millimeters," he explained. When speaking about the impact of the rolling mill and its output on the North American market, Jiménez highlighted that currently in both Mexico and the U.S., a significant amount of steel is currently imported from other continents.
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.
Two-high mill 2. Two-high reversing mill 3. Three-high mill 4. Four-high mill 5. 5 A large decrease in the power required for rolling can be achieved by the use of small-diameter rolls. 5. Cluster mill 6. Planetary mill 7. Four stand continuous mill 6. 6 The initial breakdown of ingots into blooms & billets is generally done by hot-rolling.

Steel Rolling. Rolling is an indirect compression process. Normally the only force or stress applied is the radial pressure from the rolls. This deforms the metal and pulls it through the roll gap. The process can be compared to compression or forging but differs in two respects in that compression takes place between a pair of platens at ...
Now it only makes sense we talk about cold rolled. Cold rolled is the next step along the line of flat-rolled steel products. The process starts with hot rolled P&O. Hot rolled is processed to a final thickness that is heavier than most sheet products. A cold-reducing process is used, which results in a thinner thickness.

In simple terms, cold rolling is the process of strengthening steel by changing its shape without using heat. Cold rolling, unlike hot rolling such as with hot rolled steel, can only occur when a metal is below its re-crystallization temperature. Where hot rolling is performed using high temperatures, cold rolling is performed at room temperature.
For decades we've helped hot rolling mills around the world improve steel quality, reduce downtime and operating costs, and use less water.
