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.
