Note d'application


The new cylindrical cutter module of the HS-F 1000 milling machine allows the production of special chips from steel and iron samples. The chips show a smooth granular morphology and are particularly suited for thermal evolution methods. In the present study we examined the effect of the circumferential scale layer of production samples on the C and S content as determined by combustion analysis. For this purpose, we analyzed chips which were obtained from conical steel sample before and after removal of the scale layer. Statistical evaluation revealed no significant differences of the C and S content in chips with and without scale layer. The results demonstrate that the scale layer does not interfere significantly with the combustion analysis of production samples.
