Abstract
Free cutting steel Y15 (0. 10~0. 15C
1.00~1.20Mn
0.30S) is produced by 25t EAF-LF-657 kg ingot flow sheet at Xinin Special Steel. Test results indicated that with controlling arc furnace oxidizing end [C

Mn/S=2.77 and 0/S=0.059 in steel
most inclusions in steel were (Mn
Fe)S and sulfide wrapped up oxide
and a small number of inclusions was MnS to enable the steel having excellent cutting property.
