Technical Features of Truck-based"One-ladle HM Transportation System"in Handan Steel New Area
This paper expounds the application of the truck-based"one-ladle HM transportation"technology in Handan Steel New Area from the aspects of transportation mode,transportation vehicle,interface arrangement,transportation process,management of number of transported ladles,support of new technologies and safety control.The operation practice reveals that when the daily output of No.1 BF is 8600t/d,9 on-line HM transportation vehicles and 10-12HM ladles are involved,the turnover rate of the ladles is about 6.0 times/d averagely,and the HM temperature drop is reduced to about 95 ℃;If the HM loading deviation of the transportation vehicles is controlled within±0.5t,the direct charging ratio to steelmaking vessel hits 99.5％,and the average HM charge temperature to the steelmaking vessel is increased by 60-70 ℃.It is believed that the truck-based"one-ladle HM transportation"technology is characterized by compact layout,low investment,high produc-tion efficiency,high turnover rate of HM ladles,small HM temperature drop,energy saving and environmental protection,etc.,and it will have bright future.
