In the production process of strip tandem cold rolling mills, flatness control system is important for improving quality. The efficiency actuators a pivotal factor affecting accuracy. At present, data-driven methods to intelligently identify have become research hotspot. this paper, wavelet transform longitudinal denoising method, combined with genetic algorithm (GA-WT), proposed handle big noi...

Micromagnetic NDT techniques like the measurement of the magnetic Barkhausen noise, the incremental permeability and the harmonic analysis of the tangential magnetic field allow deriving inspection procedures to online monitoring and control machinery parts and components in production processes in order to characterize mechanical properties like hardness, hardening depth, yield and tensile str...

To reduce logistics scheduling costs and energy consumption, this paper studies the slab allocation hot-rolling integrated optimization problem that arises in practical iron steel enterprises. In problem, slabs are first allocated to orders then sent heating furnaces for heating; then, they a mill rolling. A 0–1 integer programming model is established minimize attribute difference cost between...

Abstract. The technological process of manufacturing cold-rolled strip with a thickness 0.5-1.5 mm from high-strength steel grades on cold rolling mills can consist 2 or even 3 operating cycles "cold - intermediate annealing". This is due to significant hardening such steels during and, as result, limitations the maximum allowable forces. Each additional cycle annealing" significantly increases...

A new principle of on-line crook measurement for long size rolling stock while running is devised, instead of customary off line static measurement. Rolled steel beams and plates aretransferred on roller tables generally accompanied with the motion of traverse and rotation. Therefore, the following three measuring methodes are described. (1) For the case of both traverse and rotation are neglig...

There is a general agreement between researchers that particle size of poultry feed should be between the size ranges of 600-900 µm. This study investigated the particle size of poultry feed produced in the Dormaa Municipality of Ghana. A survey was conducted on various feed mills which were made up of nine on-farm mills and five community-based commercial mills. Feed samples were collected fro...

Purpose. Experimental study on microstructure, mechanical properties of pipe diversity a new type cold rolling pipe, which has the ability to perform different modes supply and rotation. Methodology. Research method is an experimental one modern industrial equipment using devices. The was conducted when pipes made steel 08Cr18Mn10Ti CRP 6-20 mills. Rolling route often 25 × 2.5 mm ® 16 1.5 mm, u...

In this paper we investigate the interaction between a granular layer and an elastic foundation using a coupled Discrete Element Method-Finite Element Method (DEM–FEM) computational model. We use this dynamics code to simulate quasi-static bending of the granular layer and we observe the changes taking place in the structure of the force chains for two cases: with and without rolling resistance...
