Abstract:Under the symmetrical cooling mode of single point non-equilibrium pouring, the surface temperature of ultra-thin beam blank BB2 (750 mm×370 mm×90 mm) section in a steel plant is uneven and the growth of billet shell is inconsistent during continuous casting. In order to improve these problems, the raw water meter was optimized by numerical simulation method. The optimized results show that the temperature difference along the drawing direction on both sides of center at narrow surface decreases from 25-110 K to 10-50 K, which decreases over 50% than before. The thickness difference of the shell along drawing direction at both sides of center at narrow surface decreases from the original 3.3-7.4 mm to 0.4-3.8 mm after leaving the mold, which is about 50% less, and the improvement effect is obvious.
