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 ...

A rolling mill cooling bed is used for the uniform air cooling of the rolled materials (bars or profiles usually referred as 'bars') and transport it in a phased manner from the entry side of the cooling bed to its discharge side. It transfers the bars one by one to the roller table, on which they are transported to the finishing section.

Each rolling stand consists of a top and a bottom roll, driven through a gearbox by an electric motor. The rolls of the stands have contours or "grooves" machined into the rolls, so that the hot billet passing between the grooves is reduced in size and shaped by each subsequent stand. Typical motor sizes for modern mills is 600kW to 1200kW ...

Steel Hot Rolling, Alloying, Tempering: The rolling of hot strip begins with a slab, which is inspected and, if necessary, surface cleaned either manually or by scarfing machines with oxyacetylene torches. The slabs are then pushed, or walked on their broadside, through gasfired furnaces that have a hearth dimension of about 13 metres by 30 metres. In a pushertype furnace, the slabs slide ...

If the mill heats the aluminum, this process is called hot working. The specific temperature range for hot working varies by alloy. For example, 3003 aluminum is hot worked at between 260 to 510°C (500 to 950°F), according to AZoM. Hot rolling prevents most or all work hardening and allows the aluminum to remain ductile.
