Description

  Semi-solid casting techniques can offer high mechanical properties and low porosity. Many commercial semi-solid processes have therefore been developed over the past three decades in order to manufacture high quality castings. The quick semi-solid slurry production method (Cup-cast method), which can prepare semi-solid slurry quickly by pouring melt into a metallic cup without the need for any expensive facilities, is one such novel semi-solid process. With this technique, pouring conditions and cup design affect temperature distribution in semi-solid slurry. The aim of this study was to investigate the effects of stirring melt at the pouring stage and cup materials on inhomogeneous temperature distribution in JIS-AC4CH aluminum alloy semi-solid slurry. Temperature measurement experiments and numerical simulations were conducted with different sizes and materials of cylindrical metallic pipes. The experimental results showed that the temperature of the semi-solid slurry at the top was lower than that at the bottom for carbon steel and cast iron pipes at 60 seconds after the start of pouring, while opposite temperature distribution was obtained when copper pipes were used. It was found that the semi-solid slurry temperature at the top decreased with increasing thermal diffusivity of pipe material and with increasing degree of stirring.
