Latest Patents
Sakaguchi's latest patents include a finish heat treatment method and apparatus for iron powder. This innovative apparatus allows raw iron powder to be placed on a continuous moving hearth and continuously charged into the system. In the pretreatment zone, the raw iron powder undergoes heating in an atmosphere of hydrogen gas and/or inert gas at temperatures ranging from 450 to 1100°C. The pretreated iron powder is then subjected to multiple treatments of decarburization, deoxidation, and denitrification. The design ensures that the ambient gases flow in the same direction as the moving hearth, optimizing the treatment process.
