Ecodesign for wear resistant ductile cast iron with medium manganese content

Abstract

Based on the reuse and recycling of manganese resource from disposed high manganese steel scraps, the wear resistant ductile cast iron of low carbon and medium manganese content was designed for grinding balls. High manganese steel scraps were used as the main charge in the melting process to replace a large fraction of pig iron, and the ferromanganese alloy was saved. The processing technology, the wear properties and the environmental impacts of the new material were studied by comparing with the traditional material KmTQMn6. The results of the experiments show that the new material has better abrasive wear resistance and lower environmental impacts. Therefore, it can be developed to a type of environmentally conscious wear resistant cast iron.
