This study established a coupled fluid-electromagnetic numerical model to systematically analyze the effects of molten steel flow, inclusion transport, and temperature gradients on refractory erosion behavior within an induction-heated tundish. The results demonstrate that increased induction heating power significantly exacerbates both flow-induced erosion and magneto-thermal corrosion of the refractory lining in the channel region. The erosion rate exhibits a linear increase with power (Eave=0.01151+3.735×10−6P), while the wear coefficient follows a power-law relationship (Wave=7.966×10-5P0.33676). Concurrently, a higher power level (800 kW) intensifies the inclusion collision source term by a factor of ten, substantially promoting inclusion collision, growth, and removal (increasing the removal rate by 14.86%). However, this also leads to a 51.3% reduction in the outlet inclusion particle size. This research provides a quantitative basis for balancing metallurgical benefits (temperature control and improved steel cleanliness) with the longevity-oriented design of refractory linings.
