【Abstract】 The residence time of powder is a basic transport dynamic parameter of hot metal dephosphorization pretreatment by powder injection in torpedo.Using water model,the mean residence time were analyzed theoretically and experimentally investigated.The factors which influence the mean residence time were measured experimentally. The curve and formula of the residence time distribution were then obtained.更多还原
