| Abstract: | Based on the composition requirements of ZG13Cr9Mo2Co1NiVNbNB steel,Shanghai Electric Heavy Casting & Forging Co.Ltd.formulated the trial production process of the steel.Trial production results showed that the mass fraction of N in molten steel was not more than 160 × 10-6 in LF process and the content of B was successfully controlled into the range of internal control for just once alloying of B,through the process of using the ferrochrome baked to 350 ℃ and adding 0.2 kg Ti-Fe and 0.5 kg Re2O3 per ton steel before B alloying.The trial steel accorded with its internal control in composition and its required properties. |
