介紹了電石爐短網銅管與軟纜接線板之間的一種新型連接技術? ?澆鑄熔焊技術.經過10多年的運行，實踐證明短網銅管與鑄銅軟纜接線板的澆鑄熔焊連接，與傳統工藝採用的圓錐面接觸連接相比較，具有加工工藝簡單、運行可靠性高、經濟效益好等優點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 computer simulation results showed that the effects of ingate dimension and ingate location on the rheo - diecasting were relatively small, and the casting process - design was easily to be done ; under the same condition, the semi - solid rheo - diecasting decreased the air entrapment during the mould filling process, and high quality metal castings could be obtained through semi - solid forming technology
結果表明：半固態流變壓鑄成形在不同的內澆口尺寸與位置條件下都可以獲得平穩的充型流動場，其工藝參數設計靈活；同等條件下，半固態流變壓鑄成形的型腔充填過程平穩，成形鑄件的質量優于液態壓鑄成形。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。Abstract : some important principles in the design of split box molding are discussed concerning the selection of mold joint ， the methods of location and the design of gating system. it has been proved in production that the principles discussed had great effects on the cost and quality of castings
