| 摘 要： | 锭型对钢锭凝固过程中的疏松、缩孔等缺陷有一定影响。对本体高度1 885 mm矮粗型（A）和2075mm细长型（B）两种7 t钢锭,通过铸造模拟分析温度场、凝固分数、凝固时间以及中心疏松缩孔情况进行分析对比, 7t（B）细长型钢锭本体中心长970 mm的封闭高温液相区,并且本体中心疏松率超过20%的疏松区域大约为180 cm3, 7t（A）矮粗型钢锭只有保温帽处有少量轻微疏松,本体基本没有。综合各项考虑,建议7 t钢锭采用7 t（A）矮粗型的钢锭设计。

| Abstract: | The ingot shape has certain influence on the defects such as porosity and shrinkage in the solidification process of ingot. Based on body height 2 075 mm long and slim shape (B) and 1 885 mm short and thick shape ( A) two kinds of 7 t ingot, by casting simulation analysis of temperature field, solidification fraction, analyses the effect o£ solidification time and center loose shrinkage cavity, 7 t (B) center is 970 mm long and slim ingot ontology high temperature liquid phase, closed area, and the body center loose loose rate more than 20% of the area is about 180 cm3, 7 t (A) short thick steel ingot only had A few minor loose insulation cap, basic no ontology. In this paper, 7 t steel ingots are recommended to be designed with 7 t(A). |
