The experimental study of twelve push - out specimens with different hole molds and different materials filled in holes and two composite steel - fdpcp ( full - depth precast concrete panels ) beams of a full shear connection and different hole mold, as well as a composite steel - fdpcp beams of a partial shear connection and square holes was conducted in this paper, the authors gain following results : three composite steel - fdpcp beams all have good composite action and perfect work behaviors as a whole and the composite steel - fdpcp beams is a new - style structure which should get further research and development
摘要對12個不同預留孔形、孔內不同填充材料的推出試件及2根不同預留孔形的完全剪力連接與1根部分剪力連接的鋼混凝土預制板組合梁進行了試驗，結果表明，只要預留孔形設計合理，灌孔混凝土強度得當，鋼混凝土預制板組合梁就具有良好的組合效應和整體工作性能，是一種有發展前途和廣泛應用領域的新型組合結構。 -
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。 -
Liquid - solid extrusion of composite material is a new kind of metal forming process, which has been developed in recent years with a promising practical application prospect for its simple working procedure, low cost and good workpiece performance. through a lot of experiments, the optimization and chosing method of key process parameters ( pouring temperature, mold warm - up temperature, impregnating pressure, impregnating time ) has been mastered. under the precondition of appropriate chosing these parameters, the effective control of extrusion velocity is the key of mading good workpiece. but the control of extrusion velocity remains a handwork, and it is heavily affected by such uncertainties as a handler ' s knowledge and skill about the process. in order to solve the problem, the automatic control of the extrusion velocity is studied, and a computer control system is also designed under existing condition
通過大量實驗，已掌握了關鍵工藝參數（熔液澆注溫度、擠壓模預熱溫度、浸漬時間、浸漬力）的優化選取方法。在合理選取關鍵工藝參數的前提下，擠壓速度的控制是成形出質量良好製件的關鍵。但是，目前對于擠壓速度的控制仍停留在手動控制階段，利用該工藝制備管、棒材製件的成功與否受操作者對該工藝及其設備的經驗及熟練程度等不確定因素影響很大。 -
The study on salc includes : 1 ) the study on the harmonization between aeration rate and melts thickly rate ; 2 ) the study and application of the new multi - function composite additive ( nmca ) ; 3 ) the study on the durability of salc ; 4 ) the designation of the structure of new multi - functional unbearing compound wall and fast equipment mold, etc. the results show : the additive can improve the harmonization of the workability and mechanics characteristic of salc to a certain extent ; improve the volume stability of salc under different environment by enhancing the resistance to the freeze and thaw, dry and wet circle and drying shrinkage
在salc的研究方面，主要包括發氣速度和稠化速度的協調性研究、新型多功能復合外加劑的研製、耐久性能的研究以及新型多功能非承重復合墻體結構及其澆注成型的快速組裝模具設計等內容；結果表明：科學合理的引入輔助外加劑在一定程度上使salc材料的工作性及相應物理力學性能得以最佳匹配，增強了salc材料對凍融循環、干濕循環及乾燥收縮的抵抗能力，使salc在不同的環境下均具有較好的體積穩定性。
