Flow and Heat Transfer on the Surface of Molten Steel Slag Layer in Continuous Casting Mold

Protective slag is coated on the surface of molten steel during continuous casting, flow and heat transfer state protective a decisive factor affecting inflow consumption liquid also an important prerequisite for stabilizing improving quality casting billets. Based Navier Stokes fluid momentum conservation equation energy equation, two-dimensional longitudinal numerical model describing flow/heat established. The data comes from equipment parameters process arc shaped slab machine in domestic plant. field temperature distribution are calculated analyzed, effects factors such as layer thickness shear speed status discussed. When bottom velocity increases 0.005 m/s to 0.2 m/s, maximum nozzle narrow center area 0.0012 0.0617 average near 0.0627 m/s. research results provide reference investigating complex metallurgical behavior slag.
