· In the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change in its crosssectional area.. The types of rolls used in rolling mills are depended upon the shape, size and the gap between the rolls and their contour. Because of workability and limitations in equipment, rolling is done in the ...

NKMZ rolling mill rolls are made with alloy forged steel with Chromium content of 2%, 3% and 5%. They are used in different types of rolling mills such as conventional hot strip mills, steckel mills, heavy section mills, 4Hi and 6Hi cold rolling mills, and are advantageous for the rolling of steel and stainless steel, aluminum and other nonferrous alloys.
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.

Most steel mills have rolling mill divisions that convert the semifinished casting products into finished products. There are many types of rolling processes, including ring rolling, roll bending, roll forming, profile rolling, and controlled rolling.
Continuous casting, also called strand casting, is the process whereby molten metal is solidified into a "semifinished" billet, bloom, or slab for subsequent rolling in the finishing mills. Prior to the introduction of continuous casting in the 1950s, steel was poured into stationary molds to form then, "continuous casting" has evolved to achieve improved yield, quality ...
