Six Sigma Approach

This research focused on defects reduction in spheroidal graphite iron casting process of a jackscrew manufacturer in which graphite nodularity was lower than a given specification (75%). This situation could lead to serious issues and accident to end-users. The Six Sigma approach of DMAIC was employed to identify and eliminate the problems. The result obtained after implementing the Six Sigma showed that the process capability was improved from-0.47 to 2.04, and the average per cent graphite nodularity was increased significantly from 61.49% to 86.43%.

Time Aware

That iron could be melted and cast in moulds like other metals appears to have been known to the ancient Greeks, and it is not improbable that other nations of antiquity also became from time to time aware of the property; especially if it is the fact that primitive furnaces were sometimes constructed on exposed hillsides where the winds of heaven performed the function of bellows. Philosophers in all ages must have suspected, if indeed they did not absolutely know, that iron obeyed the universal law, melting as other metals do, but under a more intense heat. The absence of iron-casting in medieval times may be ascribed to the primitive hearths in general use, which were incapable of heating the ore to the melting point, while, no real demand existing, the iron-masters were never stimulated to furnish a supply.

Production Practices

The content of magnesium in various parts of a nodular iron casting is measured by using spectrum analyzer. The results show that the skin of castings has an enrichment of magnesium, and the inner has a gradient distribution of magnesium, not an average distribution. Discussions on the results indicate that bubbles in the liquid metal would not move upward under the action of buoyancy, but migrate toward all directions and the bubble stranded below the surface of the liquid metal form blowholes, because these bubbles can not migrate with the obstruction of oxide films and dendrites. The results of production practices show that increasing carbon equivalent in the liquid metal is helpful to avoid blowhole defects.

The article presents a detailed analysis of technical and organizational problems of modernization of a phosphoric cast iron casting process. The paper indicates the need to optimize the process of phosphoric cast iron casting, and the analysis carried out in the article about the possibility of optimization of the casting process allowed us to determine the main direction of modernization of the process, oriented on a significant increase in the quality of the cast iron, as well as in the direction of a significant increase in the efficiency of the cast iron production process.
