Hot Strip Mill - an overview ScienceDirect Topics

In hot rolling mills the roll surface is also influenced by changing temperatures during each rotation, which may create fire-cracks, influencing friction and wear. A third factor of the impact on wear is roll/strip cooling. Cooling agents may be water or a water/emulsion mixture.

Steel Rolling Mill Machine: Hot Rolling Roll

2021-4-13  Semi-steel roll is most suitable for heavy work billet mill, large section mill, medium mill, universal section mill, hot continuous roughing mill, and hot continuous finishing mill (front section). Because its hardness is lower than that of chilled cast iron roll, and it is easy to expand when heated, it is generally not used in the finishing mill

The Hot Rolling Process - California Steel

CSI’s Hot Strip Mill includes six finishing mills, which reduce the thickness of the transfer bar down to the gauge required by the customer or the next process. The rolling speed is set to allow the last stand to perform the final reduction at the finishing temperature, between 1500° to 1650°F, specified to reach certain mechanical properties.
