In this paper, nano-TiO2lubricating fluid was chosen as an advanced rolling lubricant to investigate its effect on the hot rolled surface and metallographic structure of SS41 steel strips. The tribological performances of nano-TiO2 lubricating fluid were measured by a four-ball tribotester. The hot rolling experiments under different lubrication conditions were carried out by a four-high rollin...

This article deals with the issue of computer vision on a rolling mill. The main goal this is to describe designed and implemented algorithm for automatic identification character string billets allows conversion image information from front billet, which enters process, into characters, further used control technological process. purpose prevent input pieces being confused because different pa...

This work is devoted to the study of possibility recycling bar scrap stainless metals using radial-shear rolling. In course studies on deformation in form pins made 12X18N9T austenitic steel a rolling mill, resulting was obtained microstructure two different types: periphery an equiaxed ultrafine-grained structure with grain size 0.4–0.6 microns formed; axial zone anoriented, banded texture obt...

The mathematical modeling of the rolling process involves several parameters that may lead to non-linear equations of difficult analytical solution. Such is the case of Alexander's model (Alexander 1972), considered one of the most complete in the rolling theory. This model requires excessive computational time, which prevents its application in on-line control and supervision systems. In this ...

It has great significance to research the dynamical reliability probability of rolling mill rolls system for improving its stochastic dynamical reliability and products quality rolled. The fifth-octave vertical vibration stochastic dynamical model of rolls system was established, and the pseudo-excitation method was used to obtain the power spectral density and the variance variation characteri...
