FAQ

What type of equipment modification would be required to adapt standard steelmaking in an induction furnace to low phosphorous steel?

No additional investments are required. The NORPHOS solution allows customers to switch their production to low phosphorous steel by adding NORPHOS F 150 flux during melting operations.

Experienced installation teams are on hand help, guide or directly manage a dephosphorization stage during any operation.

What type of flux and refractory lining mix are recommended?

NORPHOS F 150 flux facilitates dephosphorization in induction furnaces by capturing the excess of phosphorous contained in steel, even at high temperatures of 1,550°C - 1,600°C.

NORPHOS works well in combination with the NORVIBE A 150 and/or NORVIBE A 1248 LG refractory linings, extending furnace campaign life while avoiding high reactivity due to chemical reactions common throughout the dephosphorization process.
