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 ...

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.

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 ...

Typical Challenges when Rolling. Rolling mill operators commonly use analytical calculation programs to compute pass schedules or pass is a multitude of different solutions in this area, but all have the common problem that they only take into account some aspects of theschedule or sequence, which are then often based on simplifications and idealizations of the process.
