The complex design of the duo coldmill, especially the pass. Aiming at this challenge, a parametric mathematical model of the pass is established in the present study. The cold rolling process of 50 pairs of tubes with reasonable actual rolling quality is simulated to obtain the change law of the rolling force. In the trial rolling test, it is found that there is a small part, which does not ...

Hot rolling is among the most widely used manufacturing techniques. However, rolling mills are major resource consumers; thus, urgent rationalisation is required in the relevant industrial systems. Roll pass design (RPD) is a principal factor that determines process efficiency, product quality and resource consumption. Therefore, it is important to optimise RPD including the selection of roll ...

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.

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. A ...

The relative difference amounted to, respectively, +% for the roll pass design used presently and +% for the new roll pass design. The verification of the results of theoretical studies on the wear of the slitting passes designed within the new pass design was performed during rolling 12 mmdiameter ribbed bars in a Bar Rolling Mill.

If the mill rolls 800,000 tons per year, it runs at an average production rate of tons/hour. If the utilization can be improved by 1 %, the available rolling hours is 365 x 24 x =, creating extra rolling hours. At tons/hour that is an additional 10,000 tons can be rolled.

For the same reasons, nobody can become an expert roll designer solely by reading this or any other book on roll pass design. This book, taken by itself, will never make a good roll designer of a stenographer or a store room clerk. What the book is intended to do and can do is to help a roll designer to do his work better and more intelligently.
