Research and Development of Third-generation High Manganese Steel Composite Frog
A new generation Ⅲ high manganese steel frog with high quality,long service life,low maintenance cost,and convenient maintenance was designed and developed to address the issues of casting defects and low service life in ordinary whole cast high manganese steel frogs.By optimizing the smelting process,the bottleneck of traditional casting technology has been broken through,and the mechanical properties of cast steel billets have been greatly improved.The introduction of the concept of composite frog manufacturing has innovated the structure of cast frog products,improved their service life,and also met the demand for online replacement.The verification results show that the maintenance and repair costs of the third-generation high manganese steel composite frog are reduced by more than 50％compared to the previous generation products,and the maximum service life(through total weight)reaches 800 million tons,which is more than 2～3 times higher.
