  • In order to explore the influence of Mg treatment on inclusions in free-cutting steel, 1144 high-sulfur free-cutting steel was used as experimental steel, and the influence of Mg composite treatment on the shape, size distribution and inclusion composition of free-cutting steel 1144 was studied by means of metallography and energy spectrometer. Experimental results show that in the free-cutting steel slab, due to Mg treatment sulfide inclusion changes from class Ⅱ into class Ⅲ and class Ⅰ, and becomes more uniform distribution, at the same time the amount of composite MnS inclusion increases. During rolling the inclusion becomes spheroidization, and its size and distribution of manganese sulfide inclusions has been improved. It is concluded that Mg treatment can effectively improve the machining performance of studied free cutting steel.
