【摘要】：运用倾转浇注法制备了半固态浆料,采用AnyCasting模拟软件确定了临界倾转速度,研究了浇注温度、料筒材料和料筒壁厚对合金液与料筒间的热平衡的影响,最后通过半固态浆料制备试验进行了验证。结果表明,当倾转速度≥18(°)/s时,合金熔体流动速度0.5m/s并存在涌动波;当倾转速度≤6(°)/s时,合金熔体流动速度0.5m/s,未产生涌动波。料筒材料、料筒壁厚和浇注温度严重影响着倾转混合过程中合金液的冷却曲线。料筒壁厚的影响最大,浇注温度的影响次之,料筒材料的影响最小。
[Abstract]:The semi-solid slurry was prepared by tilting casting method. The critical tilting velocity was determined by AnyCasting software. The effects of pouring temperature, material and wall thickness on the heat balance between alloy liquid and cylinder were studied. Finally, a semi-solid slurry preparation experiment was carried out. The results show that when the tilting velocity is 鈮，
