You''ll appreciate XRoll ® hot strip mills from SMS group as allround plants for highquality hot strip. They are designed to produce flat steel from thin strip with a minimum final gauge of millimeters to highstrength pipe steels up to millimeters thick, including stainless steel grades.
The Hot Strip Mill represents the most productive solution for flat rolled products. It provides the highest level of productivity together with a large product mix and outstanding quality. Yearly productivity of Hot Strip Mills can vary from 2 to 6 Mtpy, depending on the configuration that is selected.
The strip mill was a major innovation in steelmaking, with the first being erected at Ashland, Kentucky in 1923. This provided a continuous process, cutting out the need to pass the plates over the rolls and to double them, as in a pack the end the strip was cut with a guillotine shear or rolled into a coil. Early (hot rolling) strip mills did not produce strip suitable for tinplate ...

Hot strip mill process (HSMP) is an extremely complex process in steel manufacturing industry. Due to the increasing quality requirements of the steel products over the worldwide market, thickness, width or flatness, diagnosis of the hot strip mill process could bring significant economic and social benefits and thus becomes one of the major interesting topics in steel manufacturing industry.
HOT STRIP MILL — HIGHEST PERFORMANCE FOR NEW AND EXISTING STEEL MILLS The demand for hot rolled strip is growing in multiple ways. To remain competitive, new and existing mills must meet this challenge in the best possible way. The production of hot strip is a .
The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semifinished 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.

At the 80" hot strip mill alone, equipment checks are being performed on 7,500 points every week. "Utilizing the MTA and RCM methods with our skilled craft personnel, operators, supervisors and engineers to detect and address issues before failure is a high priority for us," said Brian Warnock, division manager, 80" hot strip mill.
Infrared sensors measure strip and sheet temperature so that rolling mill stands can be efficiently set to match the steel''s temperature. Sensors can be used to detect the presence of hot metal and accurately time the roll stand operation. Pyrometers can be used to measure the roll temperature as water cools the roll during the quenching process.
Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semifinished casting products, such as slabs, blooms, and billets.
SMS DEMAG Hot Strip Mills 10 The drumtype shear installed between the roughing and finishing mills of a hot strip mill crops the transfer bar at its head and tail. In special applications, the drumtype shear also serves to divide transfer bars and finished plates. Based on the experience gained from more than 60 drumtype shears built so far,
Hot rolling. This process stretches a slab into a strip. The slab is reheated to approximately 1250°C and rolled in hot conditions. The resultant strip steel is wound into a roll like toilet paper (hot coil). Chains for lifting; Toughrollers; Conveyor chains for conveying semifinished products

Hot strip mill. Around a third of the products we send out to our customers, are hot rolled. In the hot strip mill (Ghent), slabs coming from the continuous caster are rolled out to steel plates with a thickness of around to 13mm
COLD AND HOTROLLED STRIP PRODUCTION CONTINUOUS MEASUREMENT AND QUALITY CONTROL. The mill stand requirements for producing steel pipes are high. Pipe diameters of up to 1,800 mm are continually subjected to measurement and quality control during the production process.
Why Skin Pass Mill is necessary for Hot Strip Mill ? Lots of necessary functions 1. To get good shape (flatness) 2. To prevent coil break 3. To get smooth surface 4. To adjust coil tonnage to customer''s demand 5. To discard the scrap and secondary portion 6. To inspect coil surface Generally there isnot a hot strip mill without a skin pass mill.
