| Abstract: | The anchor chain steels SBC690 was produced by 90t electric are furnace - LF （VD） refining - 250mm ×280mm billet concasting - continuous rolling process at Beiman Special Steel . With VD treatment and whole period shield casting practice the N] was 89 ×10^ -6 ,the rating of non - metallic inclusions in steel was 0 -2, no hair crack was detected and the grain size, structure and hardenability of steel all the requirement of standard. |
