introduction： Inclusions can be divided into two types according to their sources: endogenous inclusions and external inclusions。 The common endogenous inclusions are mainly sulfide、silicate、oxide。Their number and composition in the steel are related to the composition of the steel、Smelting quality、The pouring process and the deoxidation method are related。Endogenous inclusions with high melting point，Solidification precedes the base metal，Crystallization is unhindered，It appears as a regular angular shape；Endogenous inclusions with low melting point，Due to the limitation of solidified metal，The shape is mostly ball or strip、Dendrites are distributed along grain boundaries。Sulfides and silicate components with good plasticity，When the ingot is deformed by forging，Along the main deformation direction
