摘要

为了在冷却通道内插入泡沫铜强化冷却高温铸造模具

建立了模拟高温铸造模具冷却的实验系统

研究了不同流量下泡沫铜通道和空通道的模具冷却情况。结果表明

当冷却水体积流量分别为0.1、0.2、0.3和0.4 m

/h时

使用泡沫铜通道冷却80 s后

模具同一位置的温度比空通道冷却分别低16.2、19.3、23.5和29.4 ℃

冷却排出热流量较空通道分别高414、581、659和660 W; 随着流量增加

使用泡沫铜通道的模具同一位置温度降低、局部温度梯度和热流密度增大

说明冷却通道内插入泡沫铜能够实现铸造模具的快速冷却

并可望用于顺序凝固温度控制。

Abstract

To enhance cooling of high temperature casting mold by porous copper foam inserted in cooling channel

an experimental system simulating the cooling process of high temperature casting mold was constructed

where porous copper foam was inserted into the cooling channel. Taking four flow rates

0.1

0.2

0.3 and 0.4 m

/h of cooling water

after 80 s of cooling time

the temperature at the same position of mold with insert gets 16.2

19.3

23.5 and 29.4 ℃ lower than that of mold without insert

and the heat flow rate is 414

581

659 and 660 W higher

respectively. When the flow rate increases

the temperature at the same position of the mold with insert decreases while the local temperature gradient and the heat flux increase. It is shown that the copper foam inserted in cooling channel of casting mold facilitates rapid cooling

and sequential solidification temperature controlling.
