        摘要：The influence of rotating electromagnetic field on the structure of ZA 27 alloy has been studied by means of electromagnetic stirring. An approach to the rheological structure forming mechanism has been made. In addition, the influence of the variation of the technological conditions such as alternating the rotating direction of electromagnetic field and adding alloy elements to ZA 27 alloy on the rheological structure of ZA 27 alloy has been experimentally studied.

        摘要：This paper presents a point of view and a method which is to use temperature gradient in die wall and boundary layer as estimation of quantity of heat flow of dies. Through pratical measurement and calculation, the influence of die wall temperature, metal released heat, dies wall increased heat by different cooling conditions have been researched. The heat resistance of computer solidification process numerical value simulation is 2.6 cm 2·K·s/J in the die system.

        摘要：The investigation was carried out into the technological properties of microwave silicate sand, molding and core making, casting pouring, used sand reclamation and its properties. The results showed that high strength can be obtained with less sodium silicate for microwave silicate sand,its collapsibiliy is close to that of resin sand, and the used sand is reclaimed easliy. At last in this paper the application prospect of microwave silicate sand has been forecasted.

        摘要：The structure and property of squeeze cast ZA 27 alloy were studied. The porosity defect was remarkablly reduced, the soundness increased, the structure refined and improved and the dendritic segregation reduced for ZA 27 alloy with solidification under pressure so that the ductility increased obviously. The α,β phases decomposition suppression, especially the supersaturated β phase, is the main reason for strength improvement. In addition, α,β phases decomposition also effects on ductility and toughness of this alloy.

        摘要：Using the ion probe mass spectrometer, this paper presents the carbon and hydrogen content in the steel casting produced by Evaporative Pattern Casting（EPC）. Not only carbon pick up, but also hydrogen pick up were discovered on the surface of steel casting. When the mold was made up of polystyrene foam plastics, this defect worsens the machining properties and downs the palsticity and toughness.

        摘要：The composition of Water based Coating for EPC process has been studied by controling the characteristics of coating. The effects of the composition on these properties are investigated. The results show that the foamer in coating enhances permeability effectively, improves adhesive state of powder particle and increases wear resistance. The coating property is improved because the addition of acetone makes the surface of EPS pattern mild dissolved and coarsened.

        摘要：The Cu Cr alloy with a chromium content of 0.4%￣1.0% processes a good electric and heat conductivity. Strengthened by heat treatment its casting will show a favorable complex mechanical properties. As a new material, the alloy has found its extensive use in electronics industry and electrical equipment in recent years for the electric contact plate, contact ring, clamping part etc. The Cu Cr alloy tends to be oxidized and gas absorbent etc, with a narrow range of solidification and is liable to form shrinkage cavities due to the large shrinkage. All these will bring us the trouble for the production of a superior Cu Cr alloy casting. The authors will discuss the melting and casting technology to produce Cu Cr alloy casting, employing usual melting equipment and molding materials. The electric contact plate withstanding high voltage and current will serve as an example.

        摘要：The mew fluxes for magnesium alloy are developed. Composed of some chlorides and fluorides of alkali metals and a few other inorganic substances, these fluxes show a very good comprehensive performance in relation to the melting point, density, viscosity, slag forming capacity and so on. Compared with the traditional fluxes, these new fluxes have better spreading performance, longer holding capacity, better parting ability with the melt, lower amount of harmful gases release. The five year’s application has demonstrated that they can effectively keep the Mg alloy melt from oxidization, improve its metallurgical quality, and have great significance in the environment protection.
