摘要

用差热分析法(DTA)测定了含0.000 9%~0.003 0%Ca的0.14%~0.76%C-0.48%~1.48%Mn钢及不含Ca的0.15%~0.63%C-0.56%~1.32%Mn钢的液相线温度。通过比较分析测定值和计算值

得到钙元素对钢液相线温度的影响系数A值的平均数为-0.142 5

并对传统液相线温度计算公式进行了修正

提高钙处理钢水浇铸时过热度控制的精度。

Abstract

The liquidus temperature of steel 0

14% ~ 0.76% C

0.48% - 1.48% Mn containing 0.0009% ~ 0

003 0%Ca and steel 0

15% ~ 0.63%C

0.56%~1.32%Mnfree Ca has been measured by differential thermal analysis method (DTA)

With comparison between analysis value and calculation value

it is obtained that the average influence coefficient A value of calcium element on liquidus temperature of steel is - 0.142 5

and the accuracy of overheat control during casting calcium treated molten steel is improved by amending conventional steel liquidus temperature formula.
