SMS group Hot strip rolling mills 4 X-Roll® hot strip mills from the SMS group are all-round plants for the manufacture of hot strip. Their product range extends from thin strips with a mini-mum 1.2 millimeters final gauge to high-strength tube steels with a thickness of 25.4 millimeters, along with stainless steel grades. A large number of
Strip tracking in hot strip mills. In the finishing mill, steel strip is rolled from thick slabs through pairs of rollers housed in a continuous train of seven roll stands. As the strip is rolled, unwanted lateral movement, known as strip tracking, can cause the strip to collide with the edge of the mill. Strip tracking control is currently a ...
The production of hot strip is a key element of steel production. Since close to half of all steel produced is hot-rolled to strip, mills require maximum throughput and availability combined with geometrical precision and the ability to create …
The results show that the amount of steel rolling increased by 57%, the amount of heavy rolling decreased by 23%, and the energy consumption also decreased by 10%; the synthetic lubricant used by qudian steel in 1422mm hot strip mill and the first four stands of finishing mill reduced the roll wear by 50%.
ThyssenKrupp Steel Europe spent a quarter of a million euros on renovating its hot-strip rolling mill in Duisburg. The animation shows how it all works.
Running a hot strip production facility these days places high demands on the future viability of the equipment. Our hot rolling mills are capable of producing flat steel from thin gauges of 1.2 mm to high-strength steels up to 25.4 mm thick, including stainless steel.
During hot rolling, steel is deformed at roll bite at temperature ranging typically from 850 to 1150 °C. Under severe cyclic mechanical and thermal loads and in presence of abrasive scale, wear of rolls is inevitable. The paper reviews adverse effect of roll wear on performance of the HSM. Factors responsible for higher wear rate of rolls have ...
Based on a model of microstructure evolution, an appropriate rolling schedule has been worked out to produce ultrafine grained steel (2 to 5 μm) on the hot strip mill.
The Hot Strip Mill Production Scheduling Problem: A Tabu. sultant strip is then sent to the finishing mill, where there are several rolling stands to progressively re- duce the thickness of the steel strip to a required final gauge (from 1.39 to 6.19 mm). the thin strip, thousands of feet in length, goes to the toiler to form the final product, the steel coil. to warm up the rolls (break-in ...
