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
1. lubriion, roll cooling, inter stand and skin cooling, 2. bending, shifting, prediction of roll forces and looper tension. The first set of tools are there for the surface quality. Actually, the ir goal is to avoid fini shing mill rolled in scale. In case the scale is not able to deform to the same extent as the steel, it .

Hot rolling mill thus helps in reducing the size of a metal thereby molding it into the desired form and shape. Rolling mills perform the function to reform the metal pieces such as billet and ingot whilst maintaining its well equipped micro structure into bar, wire, sheet, strip, and plate. Hot rolled products are frequently egorized

In the metals industry, tandem hot strip rolling mills are used for rolling out thick semi nished products,, slabs, to thinner at products. The product, which is often referred to as strip, is clamped in each mill stand of the rolling mill train (cf. Fig. 1). As longitudinal tensile stresses in the strip have a signi cant in uence on the
• a mill stall due to a "slab sticker", Hard and Soft Spots: • rolling accidents such as strip welding, wrong These surface and/or subsurface defects preset of the roll gap etc. appear as circular or semicircular, white or grey spots http: // (C)International Journal of Engineering Sciences Research Technology [151159 ...
JSW Steel manufactures Hot Rolled (HR) coils at its stateoftheart Hot Strip Mills (HSM), at Vijayanagar (Karnataka) and Dolvi (Maharashtra). Vijayanagar HSMI and HSM2 with commissioned capacities of MTPA and 5 MPTA respectively are equipped with sizing presses and an automatic line inspection facility which makes this facility the widest Hot Strip Mill in India.
controlling strip temperature and applying high pressure water jets. Suitable roll cooling system which washes scales from rolling surface is helpful in minimizing Secondary scale pickup from work rolls to rolled strip. Mechanism of scale removal from hot surface by high pressure water jet is quite complex.
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.
04/09/2015 · Hot rolling is an essential process in steel strip production. Rolls are key components in hot strip mill (HSM). Work and backup rolls have to withstand adverse service conditions in hotrolling process, such as high thermal stress, heavy mechanical stress, and long service periods, resulting in serious wear and fatigue on roll surface.
The benefits of intermediate induction heating can also be seen in the rear area of compact hot rolling mills. In the endless rolling process for very thin strip grades or silicon steels, compact integrated induction units compensate for the temperature drop between finishing stands and maintain the right temperature level up to the end of the ...
25/02/2019 · The vibration demolding of the crystallizer leads to slab thickness deviation in continuous casting processes. Therefore, in this paper, the dynamic model of the hot strip rolling mill vibration resulting from entry thickness deviation is proposed and its dynamic characteristics are studied. First, the dynamic model of vertical vibration in the hot strip rolling mill is established based on ...

in hot strip mills, slabs of 1 50 to 250 mm thick are rolled to strip to 12 mm thick. Conventional hot strip mills consist of roughing and finishing stands. The configuration of the roughing mills varies widely. A mill with one reversing stand is called a semicontinuous mill. A mill with one reversing stand
Temperature Monitoring. Temperature Control in Hot Rolling Mills. Hot Rolling Mills are used to reheat shapes of steel to soften them enough so that they can be rolled thinner and longer through a series of rolling stands. The finished product can be either a strip.
30/03/2005 · These developed models have been integrated into the HotStrip Mill Model (HSMM), which simulates the hot strip rolling mills and predicts the mechanical properties of hotrolled products. The HSMM model has been developed by the University of British ColumbiaCanada as a part of project on the microstructural engineering in hotstrip mills.
23/03/2016 · Hot Strip Mill at Hazira celebrates 21 years of successful operations. The primary function of the Hot Strip Mill (HSM) is to reheat semifinished steel slabs nearly to their melting point and then roll them thinner and longer through successive rolling mill stands that are driven by motors.
