the Flex Mill. It consists of a thin-slab caster, a tunnel furnace, and a rolling mill with six stands and one downcoiler. Caster The cast slab thicknesses range from 55 to 85 mm (2.17 to 3.35 inches) and allow the mill to "flex" between heavy and light gauges, as well as meet reduction ratios required in producing demanding steel grades.
A precision rolling mill, built in 2003, with 140 mm roll diameter of the Prymetall company was used for the experiments. During the rolling of the OF-Cu bars the rolling force was measured. There were no forward and backward tensions applied on the copper bars and rolling speed was reduced to …

A low-carbon steel plate is 300 mm wide and 25 mm thick. It is reduced in one pass in a two high rolling mill to a thickness of 20 mm. Roll radius = 600 mm, and roll speed = 30 m min. Strength coefficient = 500 MPa, and strain hardening exponent = 0.25. Determine: Roll force Roll torque.
A Hille-100 rolling mill with rolls of 225 mm diameter and 254 mm length, driven by a variable speed DC motor of 75 horse power, was used. The maximum rolling force, torque and speed are 1500kN, 13kN-m and 70 rpm respectively. The sensor roll nitrided surface hardness is 65 to 70 HRC.
Consider the hot rolling of a low-carbon steel strip in a single stand roughing mill. Let the entry thickness of the slab be 20 mm and its width to be 2000 mm. Its resistance to deformation is taken to be 150 MPa. It is reduced by 30% using work rolls of 800 mm diameter, rotating at 50 rpm.
A 300 mm wide strip 25 mm thick is fed through a rolling mill with two powered rolls each of diameter = 500 mm. The work-piece thickness is to be reduced to 22 mm in one pass at a roll speed of 50 rev/min. The work material has a flow curve defined by K = 275 MPa and n = 0.15.

The OD of the work rolls is between 208 to 225 mm or 145 to 155 mm, while the backup roll may be 575 to 610 mm. The length of both rolls are 700 mm, hence it can accommodate coils having width upto 630 mm. The mill is reversible and rolling takes place at speeds of 300 to 350 m/sec. 6. The work rolls for primary rolling have a rough finish.

A two-high rolling mill is assumed to be used with rolls of 250 mm diameter. The elastic modulus of the roll material is taken to be 210 000 MPa and its Poisson's ratio is 0.3. The model, developed by Roychoudhury and Lenard (1984), reviewed above, is used in the computations. As implied above, different models predict different magnitudes of ...
Hot-rolled coils (HRC) are a type of sheet product resembling a wound steel strip and are produced at hot-rolling mills. These products are widely used for construction, the machine industry, car manufacturing, the production of general-purpose, construction, oil and gas and special-purpose pipes, and as a work-piece for the further production of cold-rolled products.

4.2.3.1.1 Roll Mills. The roll mill is the simplest batch mixing equipment. The principal design consists of two horizontal rolls, usually of equal size, arranged side by side and rotating toward each other at different speeds. The ratio of the peripheral speeds of the rolls, known as friction ratio, ranges from 1 to 2 but is usually around 1.2.
An annealed copper strip 228 mm wide and 25 mm thick is rolled to a thickness of 20 mm in one pass. The roll radius is 300 mm, and the rolls rotate at 100 rpm. Calculate the roll force and the power required. For annealed copper, it has a true stress of about 80 Mpa in the unstrained condition and at a true strain of 0.223, true stress is 280 Mpa.
