Description

一种矿热炉用环保无水炮泥
【技术领域】
本发明涉及耐火材料制造的技术领域，特别是一种矿热炉用环保无水炮泥的技术领域。
【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。炮泥除了堵出铁口和稳定出铁的作用之外，还被赋予保护炉缸、延长高炉底部侧砖寿命的功能。无水炮泥一般以刚玉、碳化硅结合氮化硅、焦粉、结合粘土等为主要原料，同时配加不同的外加剂，用蒽油、洗油或焦油作结合剂，耐压强度和抗折强度较差，同时其抗氧化性和抗渣、铁侵蚀性也较差，同时也容易受热过程中放出有害气体，污染环境。
【发明内容】
本发明的目的就是解决现有技术中的问题，提出一种矿热炉用环保无水炮泥，能够使炮泥有很好的耐侵蚀性和耐冲刷性，结构强度高，使用寿命长，烘烤过程中不会产生有害气体，节能环保，利于推广。
