高炉炉缸整体浇注修复技术 |
|
高炉炉缸整体浇注修复技术是一种快速重构高炉炉缸陶瓷杯与安全传热结构的新技术。高炉炉缸使用后期,初始陶瓷杯消失,炭砖层因溶蚀、磨损、侵蚀而变薄,炉缸散热热流强度变大,且炭砖直接与铁水接触,存在炭砖持续溶蚀变薄而渗铁漏铁的隐患。本技术直接在变薄的炉缸炭砖层上浇注一层耐高温、抗渣侵蚀、不溶于铁水的整体无缝陶瓷杯,阻隔炭砖与铁水直接接触,既阻止炭溶解,也降低炉缸散热热流强度,并形成一个新的、稳定有效的炉缸传热系统,同时1150℃铁水凝固等温线离开炭砖表面向炉内偏移至新浇注的整体陶瓷杯内表面,从而实现炉缸安全长寿。
技术经济优势: 1、修复后的炉缸为薄壁炭砖+陶瓷杯结构,炉缸传热系统更加合理有效;
