摘　　要：通过生产性试验 ,提出了铬渣作水泥矿化剂的最佳工艺技术条件为 :立窑法水泥生产 ,投加量为 2 % ,炉温控制在 130 0～ 140 0℃。按此工艺条件可以使水泥强度提高 6 %～ 10 % ,并使Cr6+ 还原率达 96 .2 %。The best technical conditions of chromium containing residue acting as cement mineralizer are obtained in pilot production. The proper additive ratio of chromium containing residue in producing cement in a vertical furnace is 2%; and the temperature should be controlled at 1 300 ℃ to 1 400 ℃. With this technique, the cement strength is improved by 6% to 10%, and the reduction ratio of Cr 6+ is 96.2%.
