Simulation of Reheating Furnace for Steel Billets by a Meshless Method

A simulation of reheating furnace in a steel production line where the billets are heated from room temperature up to 1200 ˚C, is carried out using novel meshless solution procedure. The before continuous hot-rolling process should be employed dissolve alloying elements as much possible and redistribute carbon. In this work, governing equations solved by local radial basis function collocation method (LRBFCM) strong form with explicit time-stepping. diffusion for carbon concentration fields formulated on twodimensional slice. equation strongly coupled through temperature-dependent coefficient. includes these two equations. field considering position radiative convective heat fluxes boundaries. Ray tracing procedure determine flux. calculated without decarbonisation at initial macrosegregation provided casting model. comprehensive sensitivity study influence distance between total time billet performed. relation energy consumption product quality simulations. This allows automatic optimisation furnace's productivity coupling described model artificial intelligence. For first time, LRBFCM successfully demonstrated solving such complex industrial problem.
