Abstract: The 6.2 t 200 mm x 1250 mm slab ingot of 2205 dual-phase stainless steel (/% : 0.015-0.016C, 0.15-0.16Si, 1.35-1.39Mn, 0.005-0.006S, 0.023-0.024P, 22.78-22.95Cr, 5.40Ni, 3.15-3.17Mo, 0.193-0.194N) is produced by a 20 t duplex electrode series drawing ingot elector-slag remelting unit. With the process measures including using 50CaF2-19Al2O3-19CaO-6MgO-6SiO2 liquid slag series, controlling ingot drawing speed 12 mm/min and electrode melting rate 1100-1200 kg/h, the surface quality of slag ingot is better, the surface grinding amount is ≤3 mm to meet the requirement for rolling.
