Abstract

The effect of ingredient of pentary slag (/% : 50~65CaF

6 ~ 15CaO

18 ~ 30Al

4 ~ 10SiO

1 ~ 7MgO) and melting slag temperature (1330-1463 ℃ ) on its surface tension has been studied. Results show that with increasing melting slag temperature

its surface tension decreases

and the surface tension of pentary slag at 1 463 ℃ is 0.372-0.418 N/m. The surface tension of slag 60CaF

-15CaO-6SiO

-18Al

-5MgO has lower surface tension (0.375 N/ m)

better fluidity and lower viscosity value. The results of commercial production of nickel base alloys Inconel 600 and 625 by 3 t ESR

unit show that the elements content in ESR ingot are uniform

the gas content [O

the average power consumption decreases to 1 326 kWh/t from original 1933 kWh/t by remelting with slag ANF-6.
