Development of a rational roll pass design for a rolling mill

2013/01/01A new technique is developed to analyze the roll pass design of a section rolling mill. Metal forming nonuniformity and efficiency coefficients, which determine the degree of working of a metal microstructure in rolling of section bars, are used as performance criteria. The system of roll passes intended for the production of a round bar 28 mm in diameter is used as Get price

Rolling

Rolling mill operators commonly use analytical calculation programs to compute pass schedules or pass sequences. There 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.Get price

Design and optimization of rolling mills pass based on

2020/11/24The complex design of the duo cold-mill, 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 Get price
