Abstract:A water model for simulation of 1050 mm mold is established to investigate the effects of SEN structure, casting speed, immersion depth and other parameters on the fluctuation of the liquid level in the mold, the impact depth of the steel stream and entrapping of the flux, and compare the influence of different structure parameters and operating parameters on the flowing field in the mold in order to find out the best suitable compromise between the structure parameters and the operating parameters and then use them as the theoretical basis for SEN design. Actual results in Anyang Steel Works show that the rejected product rate has cut down to 0.6 % from 1.5 % since installation of the optimized SEN in the continuous slab caster in the Steel Works.
Keywords:water model  mold  SEN
