5MgO) on metallurgical quality of electro-slag ingot of S-Pb-Te free cutting stainless steel (/% : 19 -21Cr
1.5 -2. 5Mo
0. 1 -0. 3Pb
0. 25 -0. 40S
0. 03 -0. 10Te) has been tested and studied by 500 kg shielding atmosphere electro-slag remelting ( ESR) furnace. Results show that the yield of S in steel remelting by quaternary slag and quinary slag is higher than that by ternary slag ; the yield of Pb
remelting by ternary slag is relative higher; the yield of Te remelting by three kind of slag series is no-obvious difference; with SiO
2
content in steel remelting by quinary slag is 25. 0% the deviation of S
Pb and Te content in S-Pb-Te free cutting stainless steel ESR ingot from top to bottom is minimum
that are respectively AS 0. 03%
APb 0. 02% and ATe 0. 028%
and the surface quality of electro-slag ingot is best.
