单管强冷法制坯工艺对A356合金半固态坯料组织的影响
摘要
研究了管式分散强冷技术中单管强冷制坯工艺对A356铝合金坯料组织的影响。结果表明
当冷却水流量为180L/h
浇注温度为640~650℃时
所得坯料的晶粒形状接近于球状
晶粒也较细小
满足半固态成形技术对坯料晶粒组织的要求。
Abstract
Effects of technological parameters in strong cooling with single-tube on microstructure of A356 alloy semi-solid billets were described.The results show that fine grain in prepared billets is approximately spherical structure with pouring at 640
6
50℃ and cooling at 180L/h
meeting the requirements of semi-solid forming for billets.
