      摘要:ZA43 wear resistant zinc based cast alloy related in the paper belongs to a substitute matetial for Snbronze. The most remarkable chaxacter-istics of the alloy are that the zinc substitutes for copper and that the alloy is fcee fcom the rare and expensive Sn. Foe the addition of a great quantity of Al and other elements, the alloy has not only a little density, but also a good machanical. physical and processing properties. Resonable structures improve the weaxability of the alloy qreatly. The alloy is suitable for making wear resistant parts such as bush, axle sleeve and worm wheel etc. undor the conditions of high and middle load at the middle and low speed. The cast of the alloy is only a half of the Sn beonze.

      摘要:In this paper, the cup is considered as feeding resource which provides the feeding melten metal, a new method of designing the gating system for the investment steel castings has been developed. After the verification of production, the result shows that the gating system yield can increase up to 70 % by use of this method.

      摘要:The fundamental principle to develop a foundry coating is to promote the sintering of refractory particles which are burned on the casting surface, then to establish suitable conditions on which the burn-on layer could convert into ready strippable one. A clean casting surface is obtained.When this theory was applied to the development of the foundry coating for copper alloy casting , a very effective and low-cast coating was developed and also the potentiality of wide application in copper alloy casting is shown.

      摘要:A series of experiments and inspection for the using CaCl2 as a kind of hardening agent have been made in this paper through orthogonal experiments and regression analysis. Subsquently with the optimum condition, comparing experments with NH4C1 are made in production field. Results show that, not only the green bond and high temperature bond of the shell mould are higher than that of NH4C1, but also some of the shortcomings in using NH4C1 are overcomed. Meanwhile, the surface quality of the castings can be perfectly compared with.
