The slab (210 mm thick and weighing over 10 tonnes) is then transferred into the reversing rougher mill and is reduced in thickness with each pass. The steel is rolled down to about 25 mm when it is coiled in the coil box (to retain heat). It then passes through the finishing mills to achieve its final thickness.
Sometimes, a product cannot be contaminated from the iron of the steel balls.

The prime role of the Hot Rolling mills is to produce cross-sections of steel and stainless steel at different dimensions using billets of steel. The entire process of manufacturing usually involves using steel that passes through the rolling mills at elevated temperature. The rotating rolls actually roll on to decrease the thickness of the ...
HSS rolls, often installed in the earlier stands of hot strip mills, provide improved wear resistance along with a better surface roughing resistance. However, HSS are rolls more sensitive during operation and require a higher grade of attention with regard to roll cooling than High-Cr rolls. HSS rolls need an adequate mill operating environment
