Easy replacement of segment roll for maintenance Power cooling (Enhanced strip cooling system) Hot strip mills often reach their limits in terms of power and flexibility for production of advanced high strength steel grades (AHSS) such as API X80/X100, dual-phase, martensitic and complex-phase grades.

2021-1-18 Examples are suitable roll cooling and lubricationsystems to fully utilize the advantages of HSS rolls in hot strip mills, and selective roll cooling systems as a method to control the flatness of the strip in cold rolling mills. Cooling and lubricating is furthermore essential …

5.4.1 Hot rolling of steel. Hot rolling of a 50 mm thick C-Mn steel slab, reduced by 25% in one pass, is presented below. The slab is heated to a uniform temperature of 1050 C and cooled for 15 seconds in air. The process parameters are: roll radius 340 mm, roll velocity 22 rpm, and the friction coefficient is 0.25.

MILL LOAD - Roll Force, Torque, Power The Mill Load application is specifically developed for mill design/operation engineers to calculate roll separating force, rolling torque and power, etc. Typically, load calculation is needed for an existing mill when a new rolling process is applied either with higher reduction or in lower temperature or higher speed, or for a stronger material.

the rolls and re-feeding it into the nip until all the ingredients are added. Mills are used not only for blending of compound (open mill mixing) but also warming of pre-mixed compound (known as warming or cracker m ills), or for cooling compound mixed in an internal mixer (known as dump mills).

A low-carbon steel slab with the chemical composition of 0.08% C, 0.35% Mn, and 0.05% Si (wt%) was hot rolled with initial temperature of 1280 C and initial thickness of 204 mm, width of 1053 mm, and length of 9680 mm where work-roll diameters in R1 and R2 stands are 1093 and 1160 mm, respectively, and work-roll diameters in finishing mills ...

The use of roll gap lubrication system in combination with work roll cooling and antipeeling systems in hot rolling mills is discussed. The roll gap lubrication is used to reduce rolling loads and ...

Roll forging In this process, the bar stock is reduced in cross-section or ... for a T die for a T-shaped extrusion made of hot-work ... Pattern obtained at high friction or with cooling of the outer regions of the billet in the chamber. This type of pattern, observed in metals whose strength increases rapidly with

Nov 30, 2002 In the metalworking rolling process in hot and cold rolling mills, heat is generated by friction and deformation in the mechanical forming of the rolling stock. As a result, efficient cooling of the rolls as well as the surrounding roll area is essential for the forming process in order to ensure stable roll temperatures and effective heat conversion or removal.

Dec 01, 2008 A computer model is developed for work roll cooling system in hot strip mill. Using the finite difference method under unsteady conditions the energy equations for the work roll with variable boundary conditions are solved. The model has been verified with the experimental data from Mobarakeh Steel Complex (MSC).
