Such effective measures as adopting optimum parameters of power transmission,forming refining white slag with microfoam as early as possible,optimizing modes of bottom blowing,accurate temperature control as well as optimizing dust removal control and electrode wrench are taken through experiments of multiple heats aiming at such phenomena as oxi-dation,melting loss,thermal vibration and drop out of electrode easily occurred during the heating process of ladle furnace. As a result,the consumption of electrode for ladle furnace is decreased from 0. 544 kg/t in 2021 to current 0. 347 kg/t so that stable and trouble-free operations of smelting for ladle furnace is ensured as well as cost decreasing and benefit in-creasing and high efficiency continuous casting are achieved.
