Process route of Blast Furnace LD Steel making – Ladle Refining – Continous Casting of billets ensures the right and desired quality with minimum tramp elements and sulphur and phosphorus content of 0.005 0.035%, Cast billets are hot rolled in state-of-the-art MORGAN and DANIELI rolling mill, which ensures uniform dimensions and properties in each bar.Sur face finish of each bar is excellent as the mill employs tungsten carbide rolls against conventional rolls. Each bar is thermomechanically treated. After leaving the last stand of the rolling mill, the bars are quenched O(rapid cooling) in water from final rolling temperature of about 1050C. The quenching is partial, only until outer surface layer has been transformed from austenite to martensite. Because of partial quenching, a part of the original heat remains in the core of the steel and on the cooling bed, this migrates towards the surface and results in an automatic self tempering process where the surface layer of martensite is tempered. The resulting tempered – martensite shows improved deformability as compared to quenched martensite.On atmospheric cooling on cooling bed. austenitic core is transformed into ductile ferrite-pearlite. The core of the heat treated bars consists of ferrite and pearlite while strong outer layer consists of martensite.
