Step 6, cooling: carry titanium residue and be transported to the cooling of slow cooling district by chassis of slagging tap (14), enter after crushing at deep processing Reason；Alloy is transported to the cooling of slow cooling district by going out alloy chassis (16), enters deep processing after crushing and processes；
Step 7: promote graphite electrode, promote and water cooled cover of outwarding winding (7), with body of heater moving trolley (5) by electric furnace body (3) It is transported to slag station, enters next round operation.
8. the method for hot charging Ti-containing slag melting and reducing Titanium Antaciron as claimed in claim 7, it is characterised in that: electricity Furnace body (3) is when slag station, and its fire door is overlapped with slag chute (2), and slag ladle and carriage (1) is toppled over hot Ti-containing slag and entered Entering slag chute (2), hot Ti-containing slag is in slag chute (2) flows into electric furnace body (3).
9. the method for hot charging Ti-containing slag melting and reducing Titanium Antaciron as claimed in claim 7 or 8, it is characterised in that: Water cooled cover (7) upper stage is fixed with threads feeding apparatus (11), and water cooled cover (7) has suitable hello silk hole；Water The charging aperture of black furnace lid (7) is equipped with material blanking tube；In the smelting process described in step 3, the reducing agent in additive is by feeding Silk device (11) adds in electric furnace body (3) through feeding silk hole, and other adjuvant in additive adds electric furnace body by material blanking tube (3) in.
10. the method for hot charging Ti-containing slag melting and reducing Titanium Antaciron as claimed in claim 7 or 8, its feature exists In: step one loads TiO in the hot Ti-containing slag in electric furnace body (3)2Content is 15%～55%.
