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 its cross-sectional area.. The types of rolls used in rolling mills depend upon the shape, size, and gap between the rolls and their contour. Because of workability and limitations in …
The second high-speed finishing mill unit of the Wire Rod Division adopts a 10-pass 45-degree twist-free rolling mill model, and uses rolling guides when the oval rolled piece enters the round pass. The function of the rolling guide is to ensure the smooth bite of the rolled piece and the smooth progress of rolling during the rolling process.
Two roll pass sequences were developed by analytical methods and then optimized using 2.5D Finite Element Method (FEM). The first one is a classical oval-round roll pass design.

Sprinkle with sugar-cinnamon mixture, raisins and nuts. Beginning at a 15-inch side, roll dough up tightly. Pinch edge of dough into the roll to seal edge. Stretch and shape roll until even and is 15 inches long. Using a sharp serrated knife or length of dental floss, cut roll into 15 (1-inch) slices. Place slices slightly apart in the pan.
element-finite approach in the design of the pass. Cao [13] established a three-dimensional model of the roll superposi-tion and found that the uneven surface of the roll had a major impact on the declination of the steel edge. Lambiase [14] combined genetic algorithm and artificial network to study and verify the pass optimization of rolling ...
2.1 Multi-pass rolling-extrusion process of TWSTILR. The schematic diagram of the multi-pass rolling-extrusion process is shown in Fig. 2.And Fig. 3 shows the detailed dimensions of the mandrel. In the rolling-extrusion process of TWSTILR, the mandrel acts as a driving module to drive the initial blank movement; while the rollers act …

The rolling is a crucial plastic processing practice, through which it is possible to manufacture long products with different cross-sectional profiles and sizes [].Huang [] suggested that the roll pass design had been studied for centuries; a large amount of various data, as well as the accumulation of the design and operational …
fi guration of the rolls' working profi le. The dimensions of the rolls are related to the dimensions of the semifi nished product at the exit of the fi nal special pass in the slitting operation. Thus, the main dimensions of the rolls are also related to the di-mensions of the fi nal (third) special pass in that operation (Fig. 5).
