Abstract

Ved en fremgangsmåte for fremstilling av et hjertestykke for skinnepenser og penskrysninger med en hjertestykkespiss av karbonstål og forbindelsesskinner, blir hjertestykkespissen valset og underkastet en varmebehandling ved hvilken hjertestykkespissen over hele sitt tverrsnitt blir omvandlet til en finperlit-tisk struktur, deretter anløpes hjertestykkespissen og blir i det minste i hjuloverløpsområdet underkastet en materialfjernende behandling for fjernelse av den hjulsonestruktur som er forskjellig fra den finperlit-tiske, og i tilslutning til dette blir hjertestykkespissen sveiset sammen med forbindelsesskinner, hvorved fremstillingen av et hjertestykke forenkles og en varmebehandling i konvensjonelle anordninger gjøres mulig.
