The ingot scalpers are installed upstream of the hot rolling mill. They remove the oxide skin as well as any metallurgical impurities from the surface of the ingots. Scalping the edges reduces the amount of trimming scrap generated in the subsequent hot rolling process and keeps the work rolls clean.

Most primary rolling is done in either a two high reversing mill or a three-high continuous rolling mill. Final products from hot rolling include plates, strips and a wide variety of bars and sections. Plates and strips are normally rolled between two plain cylindrical rolls, or on four-high mills. a.

Hot rolled products are made by a hot rolling process. In that process, the process is done at a very high temperature like over 1,700 Degree Fahrenheit. For most of the metals, this temperature is re-crystallization temperature. Such Hot Rolled products are as follows: Rods Rails Plates Sheets and strip, Structural Bars, etc.

Hot Rolled Steel. Hot rolling is a mill process which involves rolling the steel at a high temperature (typically at a temperature over 1700° F), which is above the steel's recrystallization temperature. When steel is above the recrystallization temperature, it can be shaped and formed easily, and the steel can be made in much larger sizes. ...

A continuous hot-rolling mill may have a conveyor that is several thousand feet long. The steel slab exits from a slab reheating furnace onto the beginning of the conveyor. Surface scale is removed from the heated slab, which then becomes thinner and longer as it is squeezed by horizontal rolls at each mill, usually called roughing stands.

Hot rolling mills typically produce sections of steel at various dimensions from billets of steel. The manufactoring process involves passing bars of steel at high temperatures. This happens through rotating rolls to reduce the thickness and shape the sections.

Hot mills generally need more cooling and it is an advantage to have exit sprays as well as entry sprays. However, the exit sprays have more effect because the roll surface temperature is higher on the exit side. As a rule of thumb, the exit side cooling flow rate should be in the range of 2/3 of the total mill flow rate -figure 5.

The rolling process is a metalworking operation in which metal strips pass through a set of rollers to reduce sheet thickness and achieve uniform thickness throughout the sheet. The sheet is deformed along the linear axis. Typically after the rolling, metal sheets go through annealing which is done under a closed environment of nitrogen.
