The completed billets are used as the feedstock for our rolling mill or sold on the world market for use by other mills. The hot rolling process begins by reheating the previously created billets in our reheat furnace until they turn into a "plastic" state. In this photo, the billets are entering the reheat furnace.

Steel factory hot rolling mill problem definition. The function of the hot rolling mill is based upon the simple mechanism of using rolls to press steel slabs and reduce their thickness, as illustrated in Fig. 3. Before slabs can be rolled into hot rolling mills, slabs should be heated to the deformation temperature using reheating furnaces.

Rolling is the most important metal forming process. More than 95% of ferrous and nonferrous metals and alloys are processed to their usable shapes by rolling. Usable shapes of rolled metals are plate, sheet, strip, foil, different sections like rail, beam, channel, angle, bar, rod, and seamless pipe, etc., as shown in Fig. and Fig.

Coupled thermoelastoplastic behavior can be considered for modeling, and it allows evaluation of the effect of roll geometry strip profile, temperature, friction between the work rolls and the slab, thickness reduction, and speed of rotation of the work rolls in the process [ 1 ]. Simulating a complete hot rolling mill is a challenge.

In the process of copper alloy hot continuous rolling, the problem of copper sticking to the roller seriously affects the surface quality, performance, and service life of the copper products. Roll sticking occurs as the adhesion energy of Cu is lower than that of Fe and the FeCu interface, and the severe surface deformation which forces the copper into direct contact with the roll during the ...

Montanstahl's hot rolling mill forms profiles from rods having twenty to sixty millimeter diameter rather than the typical billetbased steel. The internally developed system operates using up to six small stands which has reduced tooling costs as a consequence. So we can produce maller batches: a minimum run for a carbon steel section is 15 ...

Steckel mill, also known as a reversible finishing mill is like a reversing rolling mill except two coilers are used to feed the material through the mill. One coiler is on the entrance side and the other on the exit side. The coilers pull the material through the mill; therefore, the process is more like drawing than rolling.

In the case of valuable coldrolled Cu/Al clad plates, billet surface treatment before rolling is a significant process that can affect the bonding efficiency and quality. While the current studies primarily focus on the influence of rolling parameters, insufficient attention has been paid to surface treatment. In this study, the effects of mechanical surface treatment on the bonding mechanism ...

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.
