用玻璃纤维过滤网作铝合金铸件易割冒口片取得了较好的效果.经试验和生产验证,对于直径中φ90mm的冒口,采用补缩通道为φ15~40mm的玻璃纤维过滤网作易割冒口片,生产的铝合金铸件(30~40kg重),冒口容易除掉,冒口根无任何缺陷,成品合格率100%.不仅减轻了劳动强度,改善了工作环境,而且省去了锯冒口设备.
With glass fiber filter for aluminum alloy castings easy to harvest riser achieved good results.According to the test and production verification, for the diameter of φ90mm riser, the use of filler channel φ15 ~ 40mm for the glass fiber filter for easy Risers, the production of aluminum alloy castings (30 ~ 40kg weight), riser easy to get rid of riser root without any defects, the finished product pass rate of 100%. Not only reduced the labor intensity and improve the working environment, and save Saw saw riser equipment.
