摘要 采用1:2.4缩小动态物理模型,对南钢辊径1 200 mm、辊宽380 mm、液面深度460 mm的双辊2- 3 mm薄带连铸机熔池布流进行模拟和水口结构进行了评估。并采用正交设计试验,对水口结构尺寸进行了优化。结果表明,水口上下倾角为0、左右偏角60°、侧孔面积为18 mm×11 mm时,水口的综合性能最佳,能满足熔池布流的要求。 Simulation of liquid steel feeding system of pool in a twin roll 2- 3 mm thin strip concaster with roll diameter 1 200 mm, wide 380 mm and pool depth 460 mm at Nanchang Steel and evaluation of nozzle structure has been carried out by using 1 : 2.4 ratio dynamic physical model. The nozzle size structure was optimized by orthogonal experiment. The results showed that as nozzle up and down inclination is 0, both sides deviation angle 60° and side hole dimension 18 mm× 11 mm, the comprehensive properties of nozzle were optimum and can meet the requirement of feeding liquid steel into bath.
