摘要:
A process for decarburizing ferrous metals and in particular electrical steels such as motor and transformer laminations wherein metal articles are treated at temperature under a furnace atmosphere generated by injecting N.sub.2 --CO.sub.2 --H.sub.2 mixtures or N.sub.2 -methanol-CO.sub.2 mixtures into the furnace.
