The Hot Rolling Process - California Steel Industries

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 Differences Between Hot and Cold Rolled Steel rolling of steel in hot strip millNOTE Hot-rolling and cold-rolling should not be mistaken for different grades of steel. Steels of different grades can be produced as hot-rolled or cold-rolled. HOT-ROLLED STEEL. Hot-rolling refers to a mill process in which you roll the steel at a temperature above its recrystallization temperature; a heat that typically exceeds 1000° F.

Steel - Hot strip Britannica

Steel - Steel - Hot strip 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 gas-fired furnaces that have a hearth dimension of about 13 metres by 30 metres. In a pusher-type furnace, the slabs slide on water-cooled rolling of steel in hot strip millScale formation and its removal in Hot Rolling processDuring hot rolling of steel, its surface is exposed to air which leads to oxidation, resulting in scale formation. The scale formation is affected by the temperature, steel grade, surrounding atmosphere and the exposure time. There are two kinds of scales relevant in rolling mills sticky and dry scales.

Hot Rolling is employed for rolling of steel slabs to hot strips in hot strip mills. Like any other hot rolling operations, rolling of hot strip is also a plastic deformation of the material of the slab caused by compressive force rolling of steel in hot strip millROLLING - Primetals TechnologiesBy default, the strip width in a hot-strip mill is deter-mined by edging and rolling the strip in the roughing mill. The width deviation after the finishing mill arises from the width deviation in front of the finishing mill and from width-spread anomaly occurring inside the finish-ing mill. The behavior of width spread in a finishing mill
