The results show that the heat preservation coating and its proper thickness are favorable to the enhancement of filling mold speed of aluminium alloy ; the higher the pouring temperature is and the larger the ratio of hollow areas of vertical pouring is, the faster the speed of filling mold of aluminium alloy is ; if the mold is too thick or too thin, it may decrease the speed of filling mold ; the proper length and the area of vertical pouring are favorable to the enhancement of the speed of filling mold ; although negatire - pressure may improve filling the speed, too high negatire - pressure may enlarge the flaw in casting
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
