Abstract
A method for producing a tire rasp blade for mounting on a rasp hub is described. The tire rasp blade has a blade body and blade teeth. A main part of the tire rasp blade is austenitized by heating the main part to an austenitization temperature. The tire rasp blade is then tempered. The austenitizing process is performed by induction heating the tire rasp blade until the austenitization temperature is reached. The austenitizing process is followed by a quenching process, wherein the quenching is started before austenitization temperature is reached, whereby the quenching process briefly overlaps the induction heating. A tire rasp blade is also described.
