The rolling process is shown in Fig. : Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product.

Compact in design, CSP ® produces highquality hot strip in a single manufacturing line that combines casting, heating, and rolling. Our proven CSP ® caster with its patented funnelshaped mold casts thin slabs in thicknesses ranging from 50 to 90 mm. Next, the slabs go into the CSP ® furnace for temperature equalization. Straight after that, the CSP ® mill rolls them to final strip thickness.

Existing method of runout table drive control on the hot strip mill ensures the required strip tension by setting a difference between speeds of the delivered strip and roller bodies. Such difference results in a higher wear rate of roller bodies and their more frequent replacement, entailing high expenses. Thus, a currently important objective is to increase efficiency of runout table ...

The slab is rolled into hot strip (thickness ranging from mm to around 16 mm and width ranging from 800 mm to 1880 mm) as it passes through the finishing mill of 5, 6 or even 7 stands. The hot strip after rolling enters the run out table (ROT) where it undergoes laminar cooling to the coiling temperature. It is then coiled to room temperature.
