Usually after pass design is done, power and force calculation should be performed to check whether the mill (roll, motor, transmission system, etc.) is strong enough to roll the product(s). For this purpose Metal Pass has developed a set of programs for mill power and force calculation, as follows:
ROLL PASS DESIGN FreeForm Series This is the FreeForm series of our roll design systems. It provides full freedom of trialanderror design for the pass and groove parameters. For every trial, the system calculates spread, forward slip, roll RPM, and all other critical parameters.
Produce a Bend Progression or "Flower.". Layout and design the Roll Forming Tooling around the flower. Incorporate fixtures, guides, side rolls, and straightening devices where applicable. After the crosssection has been finalized, and before the rolls can be designed, the proper number of passes and rolling mill must be determined.
Rolling is a continuous or noncontinuous pressure forming process with one or more rotating rollers. Additional tools can be used, such as plugs, mandrels etc. Molding occurs either through motorized rollers or by pulling rollers. Rolling is one of the most diverse forming processe in the forming technology.
In this work, a rolling simulation system for the hot rolling of steel is elaborated. The system is capable of simulating rolling of slabs and blooms, as well as round or square billets, in different symmetric or asymmetric forms in continuous, reversing, or combined rolling. Groove geometries are userdefined and an arbitrary number of rolling stands and distances between them may be used.
The input parameters used for the simulation is given in Table typical pass schedule for eight number of passes followed in the rolling simulation study is shown in Table the present study, the initial bloom has 320×400 mm 2 cross section. The bloom was rolled with initial temperature of 1235 ° this case about overall degree of deformation and reduction ratio of was ...

The production of 100 mm grinding balls using rolls with doublethreaded pass design and a discretely variable pitch is characterized by increased roll wear, which leads to characteristic surface defects on the balls. A new roll pass was designed, rolls were made, and pilot 100 mm grinding balls were rolled using new doublethreaded rolls. The results of simulating the process of rolling balls ...
Alloy steel round bar is designed to be rolled by the initial six passes of a continuous rolling process with alternatively arranged horizontal (H) mill and vertical (V) mill. The roll diameter for the first pass (H1) and second pass (V2) is 700mm and the other four passes (H3,V4,H5,V6) have the roll diameter of 610 mm.
Roll pass design is a set of methods for determining the dimensions, shape, number, and type of arrangement of rolling mill passes. Roll pass design also includes the calculation of pressing forces and their distribution on the roll passes.
WICON is a software that can be used in all levels of the company for this type of analyzes. With WICON software you can: Optimize setup of the rolling mill. Calculate process parameters.

Before you can design the rolls, you must determine the proper number of passes and the rolling mill. After calculating the estimated strip width, you can develop the flower by using the arc and straight lengths. On a typical C channel, the return leg (bend No. 2) is the first forming to be done (see Figure 2). Some designers prefer to form ...
Roll Pass Design is the most significant factor in rolling of different profiles. Rolls with stand heavy loads and °C temperature. With latest CAD and Simulation software, we formulate roll pass designs of all profiles to get stable rolling, best quality and high production rate with reduced energy consumption. Roll Pass Design
The roll pass design proposal takes into consideration the lower plasticity of certain steels. Another special requirement was the shortest possible work length of the rolls. The standard odd number of passes was used because of the presumption that the roll pass design is a preparatory sequence of the laboratory rolling mill.
The pass design of the duo coldmill refers to three aspects: the determination of the pass opening in the reduction segment, the top profile design, and the design of the pass curve of the mandrel. According to different theoretical bases, pass design can be divided into two methods.
