Mathematical Simulation in Optimisation of Roll Pass Progression

Original language description

The results concern roll pass design for rolling a round bar of a 20mm diameter from a 50mm input. Concerning materials, this roll pass design must cover a wide range of steels, from low-carbon micro-alloyed steels to stainless steels. The roll pass design proposal takes into consideration lower plasticity of certain steels. The comparison was enabled by suggesting two roll pass designs. The classical roll pass design oval-round, where the maximum extension coefficient is set to 1.55 in oval and 1.22 inround grooves. The second roll pass design uses a combination of smooth part of the roll (curves) and round roll passes. Distribution of the extension coefficient in individual passes is similar to that of oval-round series. The paper also compares values of energy-force parameters calculated analytically using the method of finite elements. If we compare the distribution of temperature, stress and size of the grain, it is proved that the oval-round roll pass designs are the best as far
