The results show that the temperature of the alloy gradually decreases from the casting mouth to the exit in the roll-shoe gap, and the isothermal line deviates from the shoe side to the roll side.

结果表明：辊靴型腔内合金的温度从入口至出口逐渐降低，合金等温线向工作辊偏移；随着浇注温度的降低，辊靴型腔内半固态区间逐渐增大；为了获得优良的半固态金属浆料，确定浇注温度为710~770 ℃；合金在辊靴型腔内层流运动时，越靠近工作辊内表面，合金的运动速度越快；随着挤压模具扩展角的增大，挤压模具出口型材宽度上中心与两侧边部合金的温度差减小；半固态合金进入模具后呈辐射状逐层向前推进填充模具扩展腔，最后再逐渐向模具出口合拢；为了改善模腔内金属流动速度的不均匀性，扩展角以45为宜。
