Application of Hot Rolling Lubrication on a Reversing Coil. 2017-11-7 began to apply the roll lubrication technology. Past studies reveal that roll lubrication can reduce the mill separating forcetorque5 and the tertiary scale thickness.6 For a 4-high hot rolling mill, roll lubrication occurs in two zones, i.e., the contact zone between the work roll and backup roll and the deforming zone in ...
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.

Jun 10, 2021 Hot Rolling Mill temperature Measurement. The Hot Rolling Mill is 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 concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled.
Difference Between Hot and Cold Rolled Steel Metal . Sep 11, 2014 Hot rolling is a mill process which involves rolling the steel at a high temperature typically at a temperature over 1700 F, which is above the steels recrystallization temperature When steel is above the recrystallization temperature, it can be shaped and formed easily, and the steel can be made in much larger sizes

In this paper, a real application of opti- mal control of a hot rolling mill is presented. It is used the state space model formulation in the minimization of the strip thickness variations. It is presented the simulation results of the control model, which is com- pared with industrial real data from process controled by traditional techniques.
Dec 03, 2015 The rolling speed is set to allow the last stand to perform the final reduction at the finishing temperature, between 820 deg C to 900 deg C, so as to achieve certain mechanical properties in the hot rolled strip. The finishing mills roll the transfer bar in tandem, meaning each bar is rolled through all the finishing stands at once.
HOT ROLLING MILLS. In a hot rolling mill process, the steel gets heated at extremely high temperature, which is generally above 1100 C. BLH Nobel can provide sensors and complete measurement systems that are highly durable and withstand the extremely harsh environment in the steel industry production sites.
Site Challenges in Hot Rolling Mill. The temperature of hot rolling is around 1000 C to 1300 C. 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.
