攀钢脱硫铁水撇渣工艺的改进
IMPROVED SKIMMING TECHNOLOGY FOR DESULPHURIZED HOT METAL AT PANGANG
-
摘要: 针对攀钢铁水条件及预处理工序的实际情况，通过对撇渣工艺的一系列试验研究，提出了切实可行的改进措施。试验结果表明，采用二合一砖撇渣器在技术上是可行的。撇渣效率达到97.6％，铁水流量为14.9t／min，满足了后序提钒工艺的要求，使钒渣中CaO含量下降到1.28％。Abstract: Based on the actual state of hot metal and pretreatment processess at pangang.the measures are proposed to improve skimming method through a series of experiments,The experimental results show the use of two in one brick for skimming is feasible. The skimming efficiency and flow rate of hot metal are 97.6% and 14. 9t/min respectively so as to meet the reguirements of vanadium recovery from hot metal. The content of calcium oxide in vanadium slag decreases to 1.28%.
