【摘要】 对转炉钒渣进行了物理化学分析，并根据转炉钒渣和多膛炉的特点，在实验室进行了系统的实验。根据小试结果，对多膛炉的焙烧工艺进行了改进，使多膛炉焙烧转炉钒渣的转化率达86．6％，浸出残渣的TV下降到1．2％左右．更多还原

【Abstract】 The physicochemical analysis was conducted of the vanadium slag produced in converter.A series of laboratory experiments were carried out according to the characteristics of the slag and multi-hearth roaster. Based on the experimental results,the roasting process in multi-hearth roaster was improved. The recovery of vanadium in the slag roasted in multi-hearth roaster reaches 86.6%. The total vanadium in the residual slag after leaching decreases to about 1. 2%.更多还原
