This paper analyzes the control of Al2O3 inclusions in high strength IF steel containing phosphorus. The inclusion statistics and two-dimensional morphology samples with slab thickness 1/8, 1/2 7/8, hot rolling, cold rolling continuous annealing processes were observed compared by ASPEX SEM. In addition, three-dimensional extracted from electrolysis original process compared. results show that:...

Based on the stochastic rolling force data from aluminum hot strip tandem mill, the ARMA time series model and the stochastic excitation power spectral density (PSD) model are established, and the stochastic rolling forces excitation model is established by utilizing Levenberg-Marquardt combined with generalized global planning algorithm. A two dimensional stochastic nonlinear dynamical model o...

A key determinant of the quality of hot-rolled strip is mechanical properties lying within the tolerance range. Traditionally, this is done by testing samples which is costly, time-consuming and ties up stock awaiting test results. An alternative is given by MicroStructureMonitor, a computer model-based system which calculates the required quality parameters rather than measuring them and addit...

Abstract The looper control of hot strip finishing mill is one the most critical items in rolling process. It a highly complex nonlinear system, with strong states coupling and uncertainty that present difficult challenge. Loopers are placed between stands not only to mass flow two but also generate constant specific tension during rolling, independent actual stock which influences width strip....

The continuous roll casting process (CRC), consisting of continuous strip casting between rolls, is now well known. It was introduced by the SCAL Company (Pechiney Ugine Kuhlmann Group) 60 years ago 1 . The process consists of solidifying aluminum or aluminum alloys between the water-cooled rolls of a duo rolling mill. From the moment when solidification is completed to the moment when the stri...
