Description
技术领域
本发明涉及耐火材料,尤其是涉及一种砌筑在加热炉炉底的加热炉用预制滑轨砖。
背景技术
加热炉是轧钢的关键设备,加热温度在1100℃左右,在加热炉炉底砌筑有滑轨,钢坯在加热炉内加热后,在滑轨上滑动前进,因此要求砌筑滑轨的滑轨砖要有较好的强度和耐磨性。
目前加热炉使用的滑轨砖多为熔铸锆刚玉材质或锆莫来石材质,但是无论哪种材质,生产时是震动机压成型还是预制成型的砖坯,都需要经过1400~1500℃的高温烧成,烧成时所用的煤气或者天然气会造成产品的成本增加,也会对环境造成污染。近几年来,随着人们环保、节能降耗意识的不断提高,耐火材料行业也在不断寻找节能降耗的办法,如果能对加热炉滑轨砖的生产工艺进行改进,不仅能节约生产成本,降低能耗,还能提高加热炉滑轨的使用寿命。
发明内容
本发明的目的在于提供一种无需高温烧成的加热炉用预制滑轨砖,不仅节约了生产成本,降低了能耗,还能提高加热炉滑轨的使用寿命。
为实现上述目的,本发明可采取下述技术方案:
本发明所述的加热炉用预制滑轨砖,是由原料棕刚玉、铬刚玉,白刚玉粉,氧化铝微粉,纯铝酸钙水泥,硅微粉以及外加复合减水剂按下述重量份配比和方法制备而成:
配比:
粒度3~8mm的棕刚玉颗粒30~40份,
粒度0.1~2.9mm的铬刚玉颗粒25~35份,200目的铬刚玉粉8~15份,
320目的白刚玉粉5~10份,
3~5μm氧化铝微粉3~8份,
纯铝酸钙水泥3~5份,
0.5~1μm的硅微粉3~5份,
复合减水剂0.15~0.3份;
制备方法:
将所有原料和适量水一起混合均匀,预制成砖坯,然后将砖坯入200℃烘干房干燥后,自然冷却,得到成品砖体。
所述复合减水剂为三聚磷酸钠和六偏磷酸钠,其中三聚磷酸钠0.1~0.2份,六偏磷酸钠0.05~0.1份。
为降低原料成本,所述铬刚玉可采用冶炼电熔金属铬的炉渣,其中Al2O3≥85wt%,Cr2O3≥10wt%。
为保证成品滑轨砖的质量满足使用要求,对所用原料的纯度有所要求:其中棕刚玉中Al2O3≥95wt%;白刚玉中Al2O3≥99wt%;氧化铝微粉中Al2O3≥99wt%;纯铝酸钙水泥中Al2O3≥69wt%;硅微粉中SiO2≥95wt%。
经测试,本发明生产的成品滑轨砖的理化指标如下:
本发明的优点在于所用原料及配比科学,生产工艺简单,减少了工人的劳动强度;原料级配合理,水泥遇水水化,各原料之间可达到最紧密的堆积,得到高强度、低气孔的砖坯;预制成型的砖坯无需高温烧成,节能降耗,减少污染,同时经过低温烘烤后可提高成品滑轨砖的强度,延长了滑轨的使用寿命。
具体实施方式
本发明所述的加热炉用预制滑轨砖,是由原料棕刚玉、铬刚玉,白刚玉粉,氧化铝微粉,纯铝酸钙水泥,硅微粉以及外加复合减水剂按下述重量份配比和方法制备而成:
1、配比:
粒度3~8mm的棕刚玉颗粒30~40份;粒度0.1~2.9mm的铬刚玉颗粒25~35份,200目的铬刚玉粉8~15份;320目的白刚玉粉5~10份;3~5μm氧化铝微粉3~8份;纯铝酸钙水泥3~5份;0.5~1μm的硅微粉3~5份;三聚磷酸钠0.1~0.2份,六偏磷酸钠0.05~0.1份;
2、制备方法:
按以上配比准确称量各原料,首先将颗粒料、细粉及外加减水剂依次倒入强制搅拌机内,干混5~7分钟,然后加入原料总量4~5%的饮用水,继续混合均匀。将混合好的浇注料,倒入模具成型,使用φ50mm震动棒震动成型,边倒料边震动,直到表面泛浆,震实,表面光滑平整。自然养护24h,脱模,自然干燥24h后,在200℃烘干房干燥24~48h,自然冷却,即可得到成品砖体。
本发明制备的滑轨砖的使用实例:
1、国内某钢厂100t/h产量的加热炉使用原熔铸锆刚玉材质滑轨砖,使用30个月后,因磨损较多,需要停炉修筑;使用本发明制备的预制滑轨砖32个月后,滑轨仅有轻度磨损,证明本发明制备的滑轨砖可以安全生产至少32个月。
2、国外某钢厂80t/h产量的加热炉使用锆莫来石材质滑轨砖,使用34个月后,因磨损较多,需要停炉修筑;使用本发明制备的预制滑轨砖36个月后,滑轨仅有轻度磨损,证明本发明制备的滑轨砖可以安全生产至少36个月。
