针对底吹氧气和天然气的复吹转炉,建立了适合该气源的熔池搅拌能计算式;同时还探讨了影响搅拌能大小的主要因素和搅拌强度随吹炼过程的变化规律。 Aiming at the compound blowing converter of bottom blowing oxygen and natural gas, the calculation formula of mixing energy of the melting pool for the gas source is established. The main factors influencing the mixing energy and the changing rules of mixing intensity with blowing process are also discussed.
