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 cm

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 cm

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).
