Process Practice of a 90 t Ladle Wire Feeding
The process practice of silicon-calcium wire(φ13 mm)feeding and aluminum wire feeding with feeding speed 2.4~3.0 m/min in a 90 t ladle for stcel 20,34Mn6 and steel BTN/1 produced by LD-LF(WF)-CC flow sheet has been summarized. The practice showed that as calcium feeding amount was up to 200×10<su...

| description | The process practice of silicon-calcium wire(φ13 mm)feeding and aluminum wire feeding with feeding speed 2.4~3.0 m/min in a 90 t ladle for stcel 20,34Mn6 and steel BTN/1 produced by LD-LF(WF)-CC flow sheet has been summarized. The practice showed that as calcium feeding amount was up to 200×10<sup>-6</sup>the residual calcium content in steel was up to maximum value -35×10<sup>-6</sup>with calcium treatment the molten steel average deoxidizing ratio was 25%, the inclusion amount in steel decreased and inclusion morphology modifed obviously; and as feeding aluminium wire,with feeding wire speed increased from 1.5 m/s to 3.0 m/s,the aluminium yield increased from 25% to 70%.The yield of aluminium normally was 60%～70% and the yield of CaSi was 15%~20%. |
