| 摘 要： | Corex是一种使用非炼焦煤及纯氧代替焦炭和空气的熔融还原炼铁新工艺。与高炉工艺相比,Corex风口区域的温度更高,风口的使用寿命是一项重大挑战。在JSW公司,更换烧坏的风口所造成的休风几乎占工厂休风时间的15%。详细分析了风口破损及生产操作参数对破损的影响,以了解破损机理和根源。所有形式的风口破损不可能用一种普遍的原因来解释,但主要的原因集中在:入炉煤粉(6.3mm)过多、煤的平均粒度偏小、渣铁倒灌、关闭风口、结瘤脱落及滑料等。

| Abstract: | Corex is an alternative smelting reduction ironmaking process where non-coking coal and pure oxygen is used instead of coke and air.The temperature of the tuyere region is much higher than in a blast furnace,and sustainability of tuyeres is a major challenge.At JSW Steel Ltd,almost 15% of the total shutdown is due to burnt tuyere replacement.A detailed analysis of tuyere failure and process parameters effecting tuyere burning was conducted to understand the failure mechanism and the root causes.A common rea... |
