HSS rolls, often installed in the earlier stands of hot strip mills, provide improved wear resistance along with a better surface roughing resistance. However, HSS are rolls more sensitive during operation and require a higher grade of attention with regard to roll cooling than High-Cr rolls. HSS rolls need an adequate mill operating environment
Aug 15, 2021 The case study on the 1580 mm hot rolling line in WISCO plant demonstrates a successful dedusting efficiency of 93.50% on the R2 rough rolling mill. The spray pressure of 0.5 MPa and the nozzle diameter of 1.4 mm are appropriate to generating the proper water droplets with the diameter of 71.1 m in order to capture the dust particles with the mean diameter of
Sep 30, 2020 Hot rolling is a metalworking process in which metal is heated above the recrystallization temperature to plastically deform it in the working or rolling operation. This process is used to create shapes with the desired geometrical dimensions and material properties while maintaining the same volume of metal. The hot metal is passed between two rolls to

Site Challenges in Hot Rolling Mill. The temperature of hot rolling is around 1000C to 1300C. The hot rolling mill having a challenging environment for making any kind of temperature measurements like high temperature and the movement of the metal, make thermocouples and other contact temperature sensors impractical.
Hot rolling begins with heating the billet or blooms to a high temperature of around 1100 degrees Celsius. The temperature is of particular importance. Hot rolling and hot extruding drawing involves working above the recrystallization point of the steel. The mill passes the heated material through a variable number of stands.

In rolling mills, intermediate steel products are given their final shape and dimension in a series of shaping and finishing operations. Most of the slabs are heated in reheating furnaces and rolled into final shape in hot or coldrolling or finishing mills. While some products (e.g. reinforcement bars, steel plates) only require hot-rolling, some others may require both hot and cold ...
Dec 03, 2015 Rolling of steel in Hot Strip Mill. Hot strip mills in these days are either conventional hot strip mills or strip mills for rolling thin slabs.

Regular use of Hot Rolling Oil A at the six finishing stand of Hot Strip Mill has demonstrated achievement of following benefits (a) Reduction in roll force and power by around 6-10%, helping in rolling of steels in critical sizes.
Cold rolling is a process that occurs after hot rolling in order to reduce the thickness, increase the yield and tensile strength and pliability of metal. It is a relatively expensive and labour-intensive process, but the improved mechanical properties increase the value of the finished product, whether that is a sheet, strip, or coil.
