Effect of an external magnetic field on improved electroslag remelting cladding process
文献摘要：
Obtaining a uniform interface temperature field plays a crucial role in the interface bonding quality of bimetal compound rolls. Therefore, this study proposes an improved electroslag remelting cladding (ESRC) process using an external magnetic field to improve the uni-formity of the interface temperature of compound rolls. The improved ESRC comprises a conventional ESRC circuit and an external coil cir-cuit. A comprehensive 3D model, including multi-physics fields, is proposed to study the effect of external magnetic fields on the multi-phys-ics fields and interface temperature uniformity. The simulated results demonstrate that the non-uniform Joule heat and flow fields cause a non-uniform interface temperature in the conventional ESRC. As for the improved ESRC, the magnetic flux density (Bcoil) along the z-axis is pro-duced by an anticlockwise current of the external coil. The rotating Lorentz force is generated from the interaction between the radial current and axial Bcoil. Therefore, the slag pool flows clockwise, which enhances circumferential effective thermal conductivity. As a result, the uni-formity of the temperature field and interface temperature improve. In addition, the magnetic flux density and rotational speed of the simulated results are in good agreement with those of the experimental results, which verifies the accuracy of the improved ESRC model. Therefore, an improved ESRC is efficient for industrial production of the compound roll with a uniform interface bonding quality.
