The steel has good hardenability, good room temperature and low temperature mechanical properties, corrosion fatigue strength and static and dynamic fracture toughness, good casting, fing, welding and machining process performance and excellent service performance (such as anticavitation abrasion resistance, low temperature performance). It has been widely used in the field of hydropower, thermal power, nuclear power industry. In this paper, we designed the technology and equipment of the Shang guan castings that the material for ZG06Cr13Ni4Mo (martensitic cast stainless steel). I used UG software to draw threedimensional shape, then used AnyCasting software to process simulation, analysised the simulation results, modifyed the process, arrived at the most reasonable process design finally. Shang guan castings required that the high strength, good wear and corrosion resistance, and not allowed to have trachoma, shrinkage. We used the furan resin sand to Modeling, the alkaline electric arc furnace return method to Melting. To ensure the quality of castings, gating system using the top note, sprue using a cylindrical, and placing the filter at the gate Cup, the cold iron in the hot junction. In the method ,we can improve casting yield,and the quality of the castings greatly. Key words: casting, casting alloy, Modification, gating system design, technology and equipment design 目錄 III — — 目 錄 摘 要 .................................................................................................................................
