研究了镁合金半固态流变成形技术及装备。结果表明 :多功能螺纹元件组合的双螺杆制浆装置制备的浆料晶粒细小 (10～ 5 0 μm) ,固相率可在 5 %～ 5 0 %范围内调整 ;封闭式加热保温、快开快关控制的浆料存储与输送装置 ,较好地解决了浆料连续制备与间歇压铸的配套 ;生产的半固态压铸件 ,强度提高了 2 0 %以上
The semi-solid magnesium alloy rheological forming technology and equipment were studied. The results show that the twin-screw pulping device with multi-function screw elements can make the slurry grains fine (10 ~ 50 μm) and the solid fraction can be adjusted within the range of 5% ~ 50% Open the fast shut-off control of the slurry storage and delivery device, a better solution to the continuous slurry preparation and intermittent die-casting supporting; production of semi-solid die-casting, strength increased by 20% or more
