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).
