摘要

西宁特钢Y15易切削钢(%:0.10～0.15C、1.00～1.20Mn、0.30S)由25 t EAF-LF-657 kg铸锭流程生产。试验结果表明

通过控制电弧炉氧化终点[C

控制钢中Mn/S=2.77、O/S=0.059时

钢中夹杂物大多数为(Mn

Fe)S和硫化物包裹氧化物

少数为MnS

使钢具有良好的切削性能。

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

0.06%~ 0. 10% and in deoxidation process to control [0

(150~250) ×10

-6

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.
