对TiN生成的影响。结果表明

试验钢TiN夹杂有两类：(1)单独TiN； (2)CaS为核心的复合TiN。20CrMoH钢中TiN夹杂较少

60Si2MnA钢中TiN占夹杂总量的50% ~60%。随铸坯中S含量的增加

) steel 20CrMoH and steel 60Si2MnA have been studied. Results showed that there were two kinds of TiN inclusion: (1) individual TiN and (2) compound TiN with core of CaS； TiN was minor in inclusions in steel 20CrMoH

but TiN accounted fbr 50% - 60% of total inclusions in steel 60Si2MnA； with increasing S content in cast billet the TiN content increased；as [Ti

the TiN number decreased from 4.4 -6.1 per cm

to 0.4 - 1

and as [S

there was no CaS-TiN compound inclusion precipitated in steel.
