Steel factory hot rolling mill problem definition. The function of the hot rolling mill is based upon the simple mechanism of using rolls to press steel slabs and reduce their thickness, as illustrated in Fig. 3. Before slabs can be rolled into hot rolling mills, slabs should be heated to the deformation temperature using reheating furnaces.

Additionally, the possible development until 2050 is analysed. The results show the high impact of continuous reheating furnaces in steel hot rolling mills on the total CO 2emissions of downstream steel processing. Furthermore, the massive increase in electrical energy consumption of the whole steel production process is highlighted.

Manual mills are gear driven, making them easier to turn than directdrive rolling mills. Their rollers have grooves so you can form square and halfround wire in addition to sheets. Electric mills do not require hand cranking, so they provide the power you need to complete high volumes of work. They have flat rollers for creating uniform sheets.
