摘要
以含铁尘泥中的碳作为还原剂,配制成具有自还原特性的尘泥团块,利用钢厂现有生产工艺和设备使其中的铁氧化物及锌氧化物实现自还原回收而不影响钢铁冶炼生产。在使用过程中发现罐衬有侵蚀现象,针对尘泥团块对鱼雷罐罐衬侵蚀问题,在罐龄、渣物化性质、渣侵蚀等方面进行了研究。研究发现尘泥团块对鱼雷罐罐衬并无明显侵蚀作用,渣流和铁流对罐的冲刷和侵蚀协同作用是影响罐衬寿命的主要原因。建议增加鱼雷罐翻渣工艺,减少罐内结渣,降低渣与罐衬接触面积和时间,同时又能够增加容铁量,减少自重。
Dust-mud briquettes were confected with carbon reducer in dust and mud containing iron, which could self-deoxidize. Ferric and zinc oxide were self-deoxidized in existing equipments, which would not affect steel-making. During the process, the torpedo lining corrosion were found. The research based on the problem of corrosion on torpedo lining caused by dust-mud briquettes were carried out. The main reason for influencing the torpedo service life was the interaction of slag flow and hot water flow. Now the original process was changed by adding a turning slag process. After that the slags in torpedo will be decreased, the contact time and area between slags and torpedo lining will also be reduced. And the capacity of the torpedoes will be increased at the meantime.
