UNA FINITURA OTTIMALE
FILI PER MODIFICA COLATA PER L’AFFINAZIONE DI COLATE IN GHISA E ACCIAIO Con l’ausilio di fili per modifica colata elementi di lega possono essere integrati in modo particolarmente accurato e ecologico nelle colate di ghisa e acciaio. Con MODIFILCORD® e MODIFILREX® la DRAHTZUG STEIN offre due fili animati di alta qualità per la finitura efficiente ed accurata delle colate in ghisa e acciaio: Infatti viene garantita un’aggiunta sicura e controllata di sostanze di difficile gestione come calcio, magnesio e titanio, senza pregiudicare in alcun modo la qualità.
Nella produzione dei fili per modifica colata DRAHTZUG STEIN gli elementi di lega più diversi vengono attentamente selezionati in base a granulometria, risultati delle analisi e purezza. I nostri marchi MODIFILCORD® e MODIFILREX® vengono impiegati per l’affinazione delle colate in ghisa e acciaio da grandi e rinomati produttori di acciaio e fonderie in tutto il mondo.
ADVANTAGES OF MODIFILCORD® AND MODIFILREX® FLUX-CORED WIRES
- Cored wire can be used with every wire feeding unit
- Cored wire can be delivered with all types of fill on customers’ request
- Constant sheath stiffness enables exact wire transportation
- Safe and controllable addition of substances that are reactive or difficult to handle such as calcium, magnesium or titanium
- Uniform filling ratio, the result of a well-controlled filling process during production
- Steel sheath thickness coordinated with the particular processes leads to optimum success in metal treatment
- High packing density of fill prevents powder seeping out of the cored wire
- Increased output relative to other processes
- Exact adaptation to all metallurgical conditions and each process
- Consistent reproducibility on each treatment
- Reduced treatment times and consequently, less temperature losses
