| Abstract: | By adopting the reasonable ingredients and following processes during smelting,such as strictly desulfurization,dephosphorization and smelting ferroalloy in primary smelting furnace,retaining the molten steel and the steel slag during steel tapping,increasing temperature to smelt the slag in LF,diffusible deoxidation and finely adjusting alloy elements contents,vacuum degassing,ZG13Cr9Mo1VNbN ultra-pure molten steel used for high pressure inner cylinder of supercritical steam turbine has been smelted successfully. |
