Optimization of casting process involves the adjustment of parameters as well as the improvement of process schemes and measures. This paper proposes a new method based on the Theory of Inventive Problem Solving (TRIZ) for casting process optimization, and realizes the Idea of applying TRIZ to optimize the casting process of a magnesium alloy intake manifold. By this method, the casting process is optimized so as to remove the shrinkage pores. The successful optimization of casting process demonstrates the feasibility of the proposed method.

By using of thermal-gravimetry (TG), the effects of oxidants on resin sand were researched. The results show that the phenolic resin begins to decompose at about 400°C; when different amounts of KNO 3 and KMnO 4 are added into resin, the initial decomposition temperature of resin decreases with different extent, and the rate of weight loss increases obviously; the collapsibility of resin is improved; the oxidizability of different oxidants has a significant influence on the initial decomposition temperature of phenolic resin; besides, the amount of oxidant has a direct proportion with the weight loss caused by the decomposition of resin.

The recent foundry technology, technological level and detection techniques of cast iron cylinder block were presented and analyzed in details in the paper. Besides, rapid development technology of cylinder block was also introduced briefly. The cast iron melting technique, the raw material control and the design of molding line and core-making machine were the primary technical gaps between China and abroad in production of cylinder block. Adopting high strength cast iron, using water cooled hot blast cupola with dust removing system as well as applying rapid development technique widely were the development trends of cast iron cylinder block. With the increased competitiveness and enhanced pro-environment consciousness, the rapid development technique and green casting technology will be developed greatly.
