以水平连铸圆坯连铸生产工艺为研究对象,采用F luent数值模拟软件凝固传热模型并结合射钉试验共同研究了管坯在不同拉坯工艺条件下,结晶器内的温度场分布与凝固传热过程,并对不同拉坯参数下铸坯试样进行了检测分析。研究发现:水平连铸拉坯工艺参数:拉速V=2.13m/m in,浇注温度T=1544℃,中间包过热度ΔT=40℃的拉坯参数下,结晶器内的温度场分布均匀稳定,铸坯质量好,产量高。研究表明,采用F luent数值模拟软件凝固传热模型并结合射钉试验可以有效分析在不同拉坯工艺条件下水平连铸结晶器内的温度场分布及凝固传热过程,并进一步制定合理的拉坯工艺参数,降低管坯质量缺陷的发生,提高铸坯质量。
The casting process of horizontal continuous casting billet was taken as the research object. F luent numerical simulation software was used to simulate the heat transfer model and nailing test to study the relationship between temperature distribution in the mold and The process of solidification and heat transfer was carried out, and the slab samples under different drawing parameters were tested and analyzed. The results show that the temperature distribution in the mold is uniform under the parameters of drawing process of horizontal continuous casting, such as drawing speed V = 2.13m / min, pouring temperature T = 1544 ℃, tundish superheat ΔT = 40 ℃ Stable, slab quality, high yield. The results show that using F luent numerical simulation software to simulate the heat transfer model combined with nailing test can effectively analyze the temperature field distribution and heat transfer in the continuous casting mold under different casting conditions and further develop a reasonable pull Billet process parameters to reduce the occurrence of defects in tube quality and improve the quality of billet.
