20SiO

5CaO) and quinary slag (/% : 45CaF

20Al

25SiO

5CaO

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

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.
