To solve the edge crack problem of AZ31B magnesium alloy cold rolling, a strong pulsed electric current was introduced to rolling process. The influence intensity, frequency, width and other parameters on cracking plate analyzed based principle single variable. According experimental results, assistance cut down inhibition effect increased obviously with larger parameters. When reached 4800 A, ...

Textures of AZ31 Mg alloy sheets were evaluated by using neutron diffraction method in this study. The AZ31 sheets were fabricated either by conventional casting and subsequent hot rolling or strip casting. The effect of warm rolling was investigated using the AZ31 Mg alloy sheet produced by conventional casting. Warm rolling of 30% thickness reduction per pass was possible without any side-cra...

Raftery, Kárnỳ, and Ettler (2010) introduce an estimation technique called Dynamic Model Averaging (DMA). In their application, DMA is used to the problem of predicting the output strip thickness for a cold rolling mill, where the output is measured with a time delay. Recently, DMA has also shown to be very useful in macroeconomic and financial applications. In this paper, we present the eDMA p...

In this paper, the wear of work roll in hot plate rolling is introduced and the parameters affecting wear mechanisms in hot strip mill are investigated. In addition, different wear mechanisms in hot rolling and the differences between these mechanisms in different stands are explained. Using the finite element method and the rolling equations, a work roll wear model is proposed. Wear is modeled...
