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
