Summary: | The invention relates iron melt improving vanadium content and controlling calcium content cooling agent and the technology, specially relates the cooling agent of adjusting the proportion of cooling agent to stabilize calcium content in vanadium slag and the technology. The technology comprises the 56-60wt% iron scale, 30-40wt% iron concentrate powder containing vanadium, and 5-10wt% anchoring agent. The method stabilizes the calcium content and iron content in vanadium slag, and effectively solves the problems of great fluctuation of vanadium slag composition and superstandard calcium and iron. By controlling the thermoregulation material to meet the requirements of the improving vanadium temperature and calcium oxide content, the method improves the vanadium slag grade and extraction rate. The invention possesses the following characteristics: 1 shortening the converting time; 2 improving the vanadium slag grade and extraction rate, and stabilizing the calcium oxide content; 3 reducing the iron loss. |
