Description

一种快硬型高炉炉缸修复料
【技术领域】
本发明涉及耐火材料制造的技术领域，特别是一种快硬型高炉炉缸修复料的技术领域。
【背景技术】
高炉铁口在长期的冶炼生产中，由于长期承受冲刷和侵蚀，出铁口炉缸侧壁变薄，形成局部异常侵蚀，铁口附近炉缸水温差、热流强度及温度较易出现偏高于正常点，导致炉缸侧壁温度升高。由于高炉炉前铁口煤气火大的现象始终没有得到有效的控制，而且随着时间的推移，四个铁口的煤气火都普遍增大。尽管高炉实施了定期的定修，有时采用喷补修复，进行铁口保护砖更换，制作永久砖压板和铁口脖子压浆作业等各种手段，以维持炉前正常生产。但经过多种技术措施处理后，铁口煤气火问题仍然没有得到有效的解决，炉前做泥套等作业仍存在困难。
【发明内容】
本发明的目的就是解决现有技术中的问题，提出一种快硬型高炉炉缸修复料，能够使修复料具有耐冲刷、耐侵蚀和抗氧化性好的特点，同时浇注后能够迅速硬化成型，以利于快速脱模，有效降低铁口区域炉缸温度，保护铁口区域炉缸砖衬。
