Abstract

Procedimento d'indurimento d'anelli d'acciaio per filatoi ed anelli trattati mediante tale procedimento. Il procedimento consiste nell'applicazione di uno dei trattamenti termici tipici degli acciai a basso contenuto di carbonio, come ad esempio la cementazione, ad anelli di filatura in acciaio ad alto contenuto di carbonio, ad esempio all'1% di carbonio.Hardening process for steel rings for spinning frames and rings treated by this process. The process consists in the application of one of the typical heat treatments of low carbon steel, such as for example case hardening, to high carbon steel spinning rings, for example 1% carbon.
