Abstract

L'invenzione concerne un procedimento per essiccare la superficie esterna di corpi cavi metallici, in particolare di tubi in acciaio, per una successiva pulitura della superficie con sabbiatura con sabbia, graniglia d'acciaio o granuli di filo d'acciaio, i corpi cavi essendo portati attraverso un induttore ad HF raffreddato e vengono portati da correnti alternate indotte ad una temperatura aumentata. Per tenere più basso possibile l'impiego di energia, si propone che i corpi cavi, mentre essi vengono portati attraverso l'induttore ad HF, vengono investiti con un flusso di un gas, il quale prima è stato riscaldato con utilizzazione del calore perduto risultante dal raffreddamento dell'induttore.
