Abstract

In the process of fabricating semi-solid slurry by strong cooling

thermal energy of the alloy melt transferring to the cooling water is controlled mainly by heat conduction

such as the materials and size of cooling pipe

the temperature and flow velocity of alloy melt as well as the flow rate and temperature of cooling water.The experimental results show that at the fixed other conditions

when the pouring temperature is increased from 620 ℃ to 630 ℃

the transfer thermal energy is increased by 1.03 times

and the flow rate of cooling water is increased from 3L/min to 4L/min

it is increased by 1.2times

while steel tube is substituted for copper tube

it is increased by 7times.
