Description
Summary:The clad teeming process can reduce the production cost of stainless steel clad plates. Nonetheless, many practical problems have not been resolved for industrialization. For the purpose, the ProCAST software is used to simulate the clad teeming process in the paper. An inverse algorithms is used to calculate the interface heat transfer coefficient based on the measured temperature curves. The temperature field and shrinkage cavity of clad ingot were simulated at different process parameters. A clad teeming experiment was carried out to prepare the clad ingots based on the simulated results. The interfacial morphologies, solidification structures and shear strength were examined. The temperature changes, shrinkage cavity, element diffusion and interfacial microstructures were analysized. The results show that the variation pattern of shrinkage cavities is in good agreement with the simulation results. The interface is well bonded with an excellent metallurgical bonding and the interfacial shear strength is up to 247 MPa in clad ingot under the experimental conditions. The diffusion of alloy elements leads to a chromized zone and a decarburized zone at the side of carbon steel and a carbonization zone at the side of stainless steel.
