Embodiment Construction
[0025] This embodiment is a method for heat recovery and recycling of waste hot steel slag empty ladle from continuous casting and rolling (CSP). see figure 1 , the process is carried out in turn as follows:
[0026] a. Pour waste heat steel slag into the empty ladle: After the CSP pouring is completed, hoist the steel ladle 8 containing the waste heat steel slag to the ladle crossing car 10 with a crane, and then drive the cross car 10 to the ladle to prepare for crossing , and then hoist the steel ladle 8 to the empty steel ladle 3 that is about to be tapped with a crane, and pour the residual hot steel slag poured from CSP in the steel ladle 8 into the empty steel ladle 3; Realize converter tapping.
[0027] b. Tapping: drive the ladle car carrying the ladle 3 of poured waste heat slag to the converter 1, and tap the ladle filled with poured waste heat slag; at the initial stage of tapping, the amount of bottom blowing argon is relatively large, and then the bottom blowin...
