結果表明：保溫塗料及一定的塗層厚度有利於提高鋁液的充型速度；澆注溫度越高、直澆道空心面積率越大，鋁液充型速度越快；模樣厚度太厚或太薄，均會使鋁液充型速度降低；一定的直澆道長度及直澆道面積有利於提高鋁液的充型速度；施加負壓會使鋁液的充型速度大大提高，但負壓過大會增大鑄造缺陷。The results show that, composite could be fabricated on the complicated surface by means of sodium silicate sand mold combination with vacuum infiltration process. when the substrate was 10 mm, composite layers reached 3 mm to 5 mm in thickness with high strength interface and less casting defect. microstructures of grey cast iron and low chromium cast iron matrix composites with various volume fraction has been analyzed
結果表明：用水玻璃砂型（芯）加負壓鑄滲的工藝能夠實現復雜表面（曲面）顆粒增強復合材料的制備，澆注方式簡單可靠，基材厚度在10mm時，復合層厚度能達到3 5mm ，且復合層鑄造缺陷少，復合效果好，界面緻密而且結合強度高。By close study on the average temperature rise, temperature distribution, and tune constant of the class f resin dry type power transformer ' s high voltage and low voltage winding under self - cooling and wind - cooling mode, we find out the connection between the variation of the load and the items, mentioned above. the results of the experiments can be reference to both thermal design optimization of dry type power transformer and the revision of current standards. meanwhile, we develop the software, which can predict the overload ability of the dry type power transformer
本文對f級樹脂澆注式乾式變壓器的高、低線圈的平均溫升，內部溫度分佈和時間常數在自冷和風冷，兩種冷卻方式下隨負載變化的規律進行了研究，得出了平均溫升、熱點溫升和時間常數隨負載變化的相互關系和有關計算用參數和公式，試驗結果可作為改進乾式電力變壓器的熱設計的依據和對現行標準進行修改的參考。The resul ts indicated that there exists obvious gas gap in molten iron flowing front, and the pressure in gas gap with eps pattern during vacuum pouring is less than 1 a tm
試驗結果表明，鑄鐵件流動前沿不僅存在明顯的氣隙，而且採用聚苯乙烯模樣材料，負壓下澆注時，其氣隙壓力低於1個大氣壓。分享友人
