英文摘要：

To calculate the carbon emission of sand casting processes and to realize the targeted energy-saving and e- mission-reduction, a modeling method for carbon emission of sand casting based on process carbon sources was pro- posed, With analyzing the feature of sand casting production processes, the process feature elements were built to describe the basic state of processing procedure. Five basic process carbon sources were constructed to compute the process carbon emission. The feasitaility of proposed method was verified through the casting production process of large box and the process carbon emission was calculated.
