| Abstract: | Trial production of JGH60 high strength steel for engineering mechanism purpose is described in the present paper. The cleanliness of the steel has been improved by adoption of such a few processes as Nb-V-Ti micro alloying, controlled rolling and accelerated cooling as well as adjustment of micro alloy elements and argon bubbling, and the morphology of sulphide changed by Ca treatment; and segregation of elements in steel reduced and the toughness of the steel raised by implementation of appropriate continuous casting process. |
