The application of an edge heater in the hot strip milling process will compensate the heat loss at the edge of the strip and thus reduces bead defect and improves the over-all quality of the strip. In this paper, we provide a 3-D model of both the edge heater and the strip, and corresponding numerical results based on the finite-element analysis. The result validates the effectiveness and efficiency...
The temperature drop, especially in the edge of the rolled steel in the hot rolling cooling has a catastrophic effect on the steel quality. Induction heating technology is thus used in the edge of intermediate billets to compensate the temperature drop. In this paper, the three-dimensional (3D) Finite Element method is employed to study the coupled eddy current-thermal field of the C-type edge induction...
To study the treatment of the slaughter wastewater treatment, application of ABR/contact oxidation process of a lab scale was carried out, taking pig excrement as the inoculation source. Research results showed that COD removal rate lied from 72.2 ∼ 94.8% of the entire process, and the anaerobic VFA levels were lower than 400mg/L0 when the water quality fluctuated, the outflow remained stable, which...
