How to improve the lifespan of the oxygen lance in lead smelting using bottom-blown furnaces?
Thread Content
The oxygen lance in lead bottom-blown furnaces is protected by nitrogen and cooling water; what measures can be taken to increase the lifespan of the oxygen lance? Please share your opinions, experts
In my opinion, during the production process, stabilizing the materials and the oxygen-to-material ratio can help increase the usage time of the oxygen lance. If you want to achieve breakthrough progress, you need to consider the materials and design; it’s best to consult an industrial manufacturing engineer.
At present, there is no oxygen lance material with better cost-performance. The proper control of the oxygen-to-nitrogen ratio and the amount of cooling water, along with the furnace temperature and the level of the lead slag, all have an impact on the lifespan of the oxygen lance.
Is a straight shape more suitable or an axe-shaped one for the oxygen lance brick sleeves (7 pieces)? What are the specifications?
