Due to the inaccuracy of preset rolling force cold rolling, there is a severe thickness defect in strip head after due flying gauge change (FGC), which affects yield strip. This paper establishes model (RFPM) by combining optimization (RFOM) and deviation prediction (RFDPM). The RFOM used genetic algorithm (GA) optimize deformation resistance friction coefficient models. RFDPM constructed using...

In order to solve the equilibrium problem related compaction degree, structural integrity of skid resistance, and resistance asphalt wearing layer on a concrete bridge deck, influence rolling mode performance was analyzed according curve characteristics, image processing technology, laser method from mechanism temperature control equipment. The results showed that degree times an SMA-13 course ...

In this paper, an analytical model based on Modified Slab Method is presented for rolling of clad sheet or double-layers in which the two layers are bounded prior to rolling. This model considers the general case of asymmetrical rolling due to unequal &#10surface speed, different contact friction, roll diameters, flow stress, and thickness ratios of the two layers. Using this model, rolling par...

Cold rolling process of a major transformation in the form of sheet metal and a wide range of steel products are produced in this way. Elastic deformation during cold rolling working rollers and the inevitable increase in the rolling force. In this study, the effect of elastic deformation during cold rolling mill rollers working on the reciprocating back and forth in tandem with the presence of...

Here, we have utilized Lateral Force Microscopy (LFM) based mechanical pushing of micro/nano-objects to study adhesion and friction characterization at the micro/nanoscale. Continuum micro/nano-friction models for particle rolling, spinning and sliding cases are discussed for general particle-substrate interfaces. A rolling resistance model using the Double-Hertz model is devoloped for such gen...

in this study, the effect of cold rolling process on the microstructure and texture evolution in 1wt. % si non-orientedelectrical steel was investigated. for this purpose, all samples were processed through single-stage hot rolling at1100 ° c and two-stage cold rolling (cross rolling and unidirectional rolling) with intermediate annealing at 650 °cfor 35 seconds. finally, all of them were fully...

Tire rolling resistance has a significant influence on fuel consumption in cars and trucks CO2 emissions. Rolling depends the tire construction, pavement texture stiffness, as well environmental traffic conditions. This article presents pilot study impact of passenger car tires. Reasons why Mean Profile Depth is not good descriptor characteristics from point view are presented, an experimental ...

We investigated the role of neutrophil microvilli in interactions with E-selectin and P-selectin in hydrodynamic shear flow by disruption with cytochalasin B, hypotonic swelling, and chilling. Cytochalasin B only marginally reduced microvilli numbers (from 30 +/- 6 to 16 +/- 6 per cell perimeter, p < 0.005) as shown by electron microscopy, completely disrupted tethering in shear flow to E-selec...
