| 摘 要： | 为优化200 mm×1 300 mm立式板坯连铸结晶器浸入式水口,采用1:1水模型模拟研究水口结构参数(侧孔断面-40 mm×80 mm,40 mm×40 mm和侧孔角度+15°和-15°)以及工艺参数(浸入深度-100～130 mm,拉速0.45～0.65 m/min)对液面波动的影响。结果表明:水口结构参数对液面波动的影响较明显;侧孔断面40 mm×40 mm,侧孔角度+15°的2#水口的使用性能相对较好;浸入深度对液面波动量的影响不大;拉速对液面波动的影响与水口结构有关,对拉速变化的敏感程度由大到小的次序是2#水口(40 mm×40 mm,+15°),4#水口(40 mm×40mm,-15°),3#水口(40 mm×80 mm,-15°),1#水口(40 mm×80 mm,+15°)。

| Abstract: | In order to optimize the submerged entry nozzle (SEN) for 200 mm x 1 300 mm vertical slab casting mold, the effect of parameters of nozzle structure (cross section dimension of side port- 40 mm x40 mm and 40 mm x80 mm, and angle of port- + 15° and - 15°) and process parameters ( submerged depth 100 ~ 130 mm and casting speed 0. 45 ~ 0. 65 m/min) on fluctuation of liquid level has been simulated and studied by 1 ： 1 water model. Results show that the effect of nozzle structure parameters on fluctuation of liquid level is more obvious and the structure of 2# nozzle with side port dimension 40 mm x40 mm and angle of port +15° has better service performance； the effect of submerged depth on fluctuation of liquid level isn' t appreciable ； and the effect of casting speed on fluctuation of liquid level relates to nozzle structure, and the descending order of sensitivity of nozzle structure to casting speed is nozzle 2#(40 mm x40 mm, +15°), nozzle 4#(40 mm x40 mm, - 15°) , nozzle 3# (40 mm x 80 mm, - 15°) and nozzle 1#(40 mm x 80 mm, + 15°). |
