Abstract: This paper describes the characteristics and shortcomings of several formulas about determining the smallest cross-sectional area in current production of nodular iron casting. Proposed a new calculate formula about minimum cross-sectional area of nodular iron casting. It is indicated being good reliability, scientific and applicability through many successful examples in production.

Abstract: The determination of pouring time is the important content in the casting process design. Pouring time to determine the design of the casting process is very important content. Appropriate pouring time can avoid many defects such as misrun, cold lap, entrapped slag, distortion, blowhole, swell, cope raise and so on. This paper analyzes the characteristics and shortcomings of determining several kinds of pouring time in current production of gray iron castings. The writer proposed a new calculate formula of pouring time about gray iron casting. By comparing the successful production instances, it is proved that it is good reliability, scientific and suitability.

Abstract: This paper described an industrial scale experience of melting as-cast high-ductility nodular iron. We discussed the rationale of selection of chemical compositions and the practice of speroidising and inoculation processes. The experimental results show that nodular iron castings with consistent quality at cast state can be produced using cupola melting technique. The castings of two heavy truck components–brake shoes and brake plates produced meet the technical requirements set in China standard GB/T1348-2009.
