摘要

绝热板、发热剂等帽部传热条件对钢锭的内部缩松、缩孔有决定性作用。采用Anycasting软件建立了某厂3.1t钢锭凝固过程的数学模型

模拟了绝热板导热系数、发热剂加入时间和发热剂加入量对3.1t钢锭内部缩松、缩孔的影响

并进行了生产试验。结果表明

绝热板导热系数不大于0.17 W·m-2·K-1时

可以很好地抑制3.1t钢锭本体内的缩松缺陷;发热剂应在浇注完成后及时加入

加入量为0.67

.33kg。

Abstract

The insulating board and heating agent play a decisive role in the quality of ingot.On the basis of Anycasting software

a mathematical model for the solidification field of 3.1tingot was established to predict effects of thermal conductivity of insulation board

heating agent adding time and addition on the shrinkage porosity in 3.1tingot

meanwhile

production verification was carried out.The results show that with thermal conductivity of insulation board less than 0.17 W ·m-2·K-1

appearance of the shrinkage porosity can be inhibited well.The heating agent should be added in time after mold casting or even earlier

and heat agent addition can be controlled in 0.67
