针对某板坯连铸机,采用1∶1的水模型,研究了不同浸入式水口的侧孔倾角、不同拉速和浸入深度对自由液面波动、冲击深度和平均停留时间的影响。研究结果表明:板坯尺寸为1 750 mm×230 mm时,建议采用的最优工艺参数为浸入式水口的倾角为向下15°,拉速为1.2～1.4 m/min,浸入式水口的浸入深度为200～250 mm。 For a slab caster, a 1: 1 water model was used to study the effect of different hole penetration angles, different pull rates and immersion depths on free surface fluctuation, impact depth and average residence time. The results show that when the slab size is 1 750 mm × 230 mm, the optimum technological parameters are recommended for the submerged entry nozzle to have an inclination of 15 ° and a pulling speed of 1.2 to 1.4 m / min. The immersion of the submerged entry nozzle Depth of 200 ~ 250 mm.
