摘　　要：连铸坯的表面和内部缺陷与结晶器内钢液的流动及夹杂物运动密切相关,因此本文以浇铸截面230mm×1 800 mm的双孔型水口板坯结晶器为研究对象,采用了数学模拟的方法研究了在4种不同拉速下板坯结晶器内钢液流动以及夹杂物运动的影响。结果表明:在双孔型水口结构条件下,最优拉速为0.7 m/min,有10.77%永久夹杂去除率。Casting billet surface and internal defects and the flow of the molten steel in the mold and the inclusion movement is closely related, therefore this article in the casting section 230 mm 1800 mm double pass groove slab crystallizer as the research object, using the mathematical simulation method is studied in four different drawing speed the flow of molten steel in slab crystallizer and the influence of inclusion movement. The results show that the double groove under the condition of nozzle structure, the optimal results for drawing speed 0.7 m/min 10.77% permanent removal rate of inclusions.
