Evolution of inclusions in ultra-high strength steel for cable sheathed steel wire
To study types and size changes of inclusions in ingot and wire of ultra-high strength steel for cable sheathed steel wire,inclusions deformability was calculated.Results show that there were many kinds of inclusions in ingot,and average length and deformability index of MnS inclusions were 4.8 μm and 1.4 respectively.In addition,the types of inclusions in steel wire were significantly reduced,and average length and deformability index of MnS inclusions were 4.2 pm and 1.9 respectively.It was recommended that forging temperature of steel ingot was 960 ℃～1 200 ℃,mass fraction of SiO2 and CaO in inclusions should be appropriately increased.
