Description

碳复合高炉铁沟浇注料
技术领域
本发明涉及耐火材料,尤其是涉及一种碳复合高炉铁沟浇注料。
背景技术
炼铁高炉是钢铁冶炼所用的重要设备之一,而高炉出铁沟则是高炉炉前的重要设施,其功能是实现液态渣和铁的分离。因为出铁沟长期储留高温铁水,其内衬长期受到渣铁的冲刷和侵蚀,工作条件非常恶劣。
随着我国大型高炉数量日趋增长,对高炉出铁沟所用耐火浇注料的要求也越来越苛刻。目前大型高炉(指2000m3以上高炉)所用的铁沟浇注料主要以Al2O3-SiC-C为主要成分,其中C是抗渣侵蚀性比较好的材料,但是容易氧化。铁沟浇注料在使用过程中,由于温度会反复的发生变化,产生的热应力会造成耐火浇注料产生裂纹甚至剥落,加上材料的氧化,造成铁沟浇注料的使用寿命较短,出铁时间一般低于100天,出铁量少(18万吨以下)。如何在高强度作业的环境下能提高铁沟浇注料的稳定性和使用寿命,是行业内技术人员的研究方向。
发明内容
本发明的目的在于提供一种碳复合高炉铁沟浇注料,该浇注料抗氧化效果好,强度高、稳定性好,使用寿命长。
为实现上述目的,本发明可采取下述技术方案:
本发明所述的碳复合高炉铁沟浇注料,是由原料电熔棕刚玉、电熔致密刚玉、碳化硅、纯铝酸钙水泥、硅微粉、双峰活性氧化铝微粉、球状沥青、碳黑粉、碳树脂粉、抗氧化剂、有机纤维、防爆剂和高效减水剂按下述重量份配比配制而成:
粒度1~8mm的电熔棕刚玉50~60份;
电熔致密刚玉8~13份,其中粒度0~1mm的颗粒料5~8份,325目的粉料3~5份;
碳化硅16~24份,其中粒度0~1mm的颗粒料8~12份,200目的粉料8~12份;
纯铝酸钙水泥1.5~2份;
粒度1μm的硅微粉2~3份;
粒度3~5μm的双峰活性氧化铝微粉5~7份;
粒度0.2~0.5mm的球状沥青2~3份;
碳黑粉0.3~0.5份;
碳树脂粉0.3~0.5份;
抗氧化剂2~2.5份;
有机纤维0.05~0.08份;
防爆剂0.08~0.12份;
高效减水剂0.1~0.15份。
为保证成品浇注料的质量,本发明对所用原料有如下要求:
所用电熔棕刚玉中Al2O3≥95%,电熔致密刚玉中Al2O3≥99%,纯铝酸钙水泥中Al2O3≥70%,双峰活性氧化铝微粉中Al2O3≥99%。
所用碳化硅中SiC≥98%;硅微粉中SiO2≥95%。
所用球状沥青的软化温度为115~120℃,其中C≥95%。
所用碳黑粉中C≥98%,碳树脂粉中C≥83%。
所用的抗氧化剂是由金属硅粉和碳化硼按1.5~2: 0.3~0.5之重量份配比配制而成。
所用有机纤维为低熔点有机纤维,其熔化温度为80~90℃。
所用的防爆剂为粒度100目的金属铝粉,其中Al≥99%。
所用的高效减水剂由德国巴斯夫FS10型和FS20型减水剂按0.04~0.08: 0.08~0.10之重量份配比配制而成。
本发明浇注料制备方法简单,将上述所有原料精确称量后混合均匀,装入防潮防晒的吨袋储存即可。
现场施工时加入5~6%的纯净水,搅拌均匀并完成施工,常规烘烤即可使用。
经测试,本发明配制的铁沟浇注料的技术指标如下表所示:
Figure DEST_PATH_IMAGE001
本发明由于加入了不同的含碳材料(碳黑粉和碳树脂粉),增加了铁沟浇注料中的碳含量,与原来主要以Al2O3-SiC-C为主要成分的铁沟浇注料相比,大大提高了铁沟的抗侵蚀性;同时主体颗粒料采用了科学的粒度级配,且对原料的纯度严格要求,保证了铁沟浇注料具有很好的高温强度、体积稳定性、抗冲刷性能、抗氧化性能,延长了铁沟的使用寿命,增大了出铁量,提高了高炉炼铁的经济效益。
