Abstract：The article analyses main technology of the 100t AC UHP Finger Shaft Furnace (FSF) which products efficiently with feeding cold material. The active power is raised 55~60MW, the second charge is released 2～5 minutes, the structure of cold material is improved, the foamy slag and liquid heel technology are used. Therefore, the questions such as furnace refractory ,dephosphorisation and shorting delay times are also noticed.The production of 44 minutes cycle per heat and 270 kWh electrical energy consumption per ton steel is reached.
