Gas Recycling Process of Magnesium Alloy Scrap

真空精馏对镁合金的气体回收进行了考察，在精馏时间2-5h内，原料温度为600℃，冷凝温度为310-350℃，在此冷凝温度范围内无明显差异。挤压负荷增大，使我考察了挤压温度350-400℃的挤压，挤压比R8-16作为真空精馏中提供的气体回收材料，挤压温度低或挤压比大的生产条件。原料Mg-Al-Zn合金比原料Mg-Al-Mn合金硬度大，而镁气回收挤压后的硬度大，强度来的有较大的强度。抗腐蚀性能良好，挤压温度对其影响无明显差异。

Gas recycling of the magnesium alloy by the vacuum distillation examined in distillation time 2-5h for raw materials temperature 600℃, condense temperature310-350℃, and there was not the clear difference in this condense temperature range. The extrusion load grew big so that I examined the production condition of extrusion temperature 350-400 ℃ of the extrusion, extrusion ratio R8-16 as gas recycling materials provided in vacuum distillation, and extrusion temperature was low or so that the extrusion ratio was big. Raw materials Mg-Al-Zn alloy was harder than raw materials Mg-Al-Mn alloy, and the hardness of magnesium gas recycling extrusions, the strength came to have a big strength. The corrosion resistance was good, and the influence of the extrusion temperature did not have the clear difference.
