Description
【技术领域】
本发明涉及耐火浇注料的技术领域，特别是一种长寿命铁沟浇注料的技术领域。
【背景技术】
铁沟是炼钢高炉引出高温铁水和熔渣的通道。在使用过程中，铁沟内衬承受着流动的高温铁水和熔渣的剧烈冲刷作用，高炉熔渣的化学侵蚀作用，铁水的渗透作用，间歇式出铁、出渣的温度急变对内衬造成的冷热震作用等。因此，一般要求铁沟内衬材料具有耐高温熔体的冲刷性要好，优良的高温耐磨性，耐高温熔渣的侵蚀，热震稳定性好，重烧体积变化小，抗氧化能力强。由于现代高炉均朝着大型、高效、自动化和高寿命方向发展，并采用精料、高风温、高压炉顶、富氧、喷煤和计算机控制等新技术以强化冶炼，因此，铁沟的工作条件随之日益苛刻，相应地对铁沟耐火材料及其施工和铁沟的通铁量提出了更高的要求。
目前，国内外铁沟所用的材料主要是A12O3-SiC-C质耐火材料，其中A12O3-SiC-C质浇注料用于铁沟的整体浇注，A12O3-SiC-C质捣打料和喷补料用于铁沟的修补。由于高炉出铁沟各部位工作环境各不相同，特别是离出铁口距离2～5m范围内的冲击区，由于受到铁水、熔渣的直接冲刷，基熔损更快。为了达到各部位使用寿命的同步，往往在铁沟使用中途高炉休风时要将铁沟冲击区进行修补，但以上各种耐火材料作为铁沟的修补料都有缺点：A12O3-SiC-C质浇注料混合物中的防爆剂不合理，该产品防暴裂性能差，不能进行快速烘烤， 否则，该产品在烘烤过程中开裂，A12O3-SiC-C质捣打料施工不方便，浪费材料多，并且施工体的各种性能、使用寿命没有浇注料好：A12O3-SiC-C质喷补料施工方便，但其施工体的各种性能、使用寿命更差。
