| Abstract: | The recent progress of high strength gray cast iron production technique was introduced in the aspects of optimizing chemical composition, increasing iron melt purity, intensifying inoculation effect, etc. By summarizing the literatures reports, it was considered that main development direction of the gray cast iron production technique is to adopt high CE, high strength, high Si/C ratio, reduce stress and improve machinability; and the main difficulty of high quality gray cast iron production is how to obtain high temperature, composition-stable and high purity iron melt and how to intensify inoculation. |
