本发明公开了一种红柱石‑莫来石‑碳化硅砖及其制造方法。材料的配方为:3‑1mmM70烧结莫来石25~35%,3‑1mm红柱石5~15%,≤1mm红柱石20~25%,≤1mm碳化硅5~10%,≤0.074mm红柱石10~20%,≤0.074mm碳化硅5~15%,硅微粉1~2%,α氧化铝微粉2~3%,外加上述原料总重3‑5%的亚硫酸纸浆废液。本发明具有良好的抗热震性、耐高温性、耐磨性,是水泥回转窑过渡带的理想耐火材料。
Description
技术领域
本发明涉及耐火材料技术领域,尤其涉及一种应用于水泥回转窑过渡带的红柱石-莫来石-碳化硅砖及其制造方法。
背景技术
由于大型干法水泥窑过渡带区域温度高,而且温度变化频繁,造成窑皮不易粘挂,成为新型干法窑的薄弱环节。过渡带耐火材料配置应考虑较高的耐火度,较高的抗摩擦性能及优良的热震稳定性。目前,一些水泥厂在过渡带采用镁铝尖晶石砖及硅莫红砖,根据对5000t·d-1大型水泥窑过渡带用后镁铝尖晶石砖损毁机理进行研究得出:水泥熟料对过渡带用镁铝尖晶石砖基本上没有侵蚀,但来自原料和燃料中的碱易沉积在砖的开气孔和晶界上,使砖的结构致密化,造成同一块砖形成不同的段带,使砖内部出现平行于砖热面的裂缝或剥落,对炉衬寿命影响极大。普通硅莫红砖采用一般矾土熟料和碳化硅为主要原料经压制干燥烧成工艺形成,结合强度不够,烧成温度欠缺,至使莫来石晶体发育不完全,其耐高温、耐磨及抗热震性能均较为一般。
为提高硅莫红砖的耐磨性,耐火砖专利CN 103833387A公布了一种高耐磨硅莫红砖及其制备工艺。由矾土熟料、碳化硅细粉、电熔白刚玉粉、红柱石粉、结合火泥外加黄糊精、甲基纤维素和水配置烧结而成,其重量配比为:粒径d>1mm矾土熟料30~35%、0.088mm≤粒径d≤1mm矾土熟料10~15%、粒径d≤0.088mm矾土熟料5~6%、粒径≤0.088mm碳化硅细粉15~25%、粒径≤0.088mm电熔白刚玉粉15~25%、粒径d≤0.088mm红柱石粉10~15%、粒径d≤0.088mm结合火泥3~5%、黄糊精0.3~0.8%、甲基纤维素0.2~0.5%、水4~5%。由于在基质中加入大量碳化硅细粉,会导致上述产品表面在氧化气氛烧成过程中生成大量釉层而造成废品;另外全部使用矾土颗粒会造成制品的热震稳定波动较大。
为了解决以上问题,本发明使用红柱石、莫来石以及碳化硅为主要原料,制备红柱石-莫来石-碳化硅砖。
发明内容
本发明要解决的技术问题是提供一种红柱石-莫来石-碳化硅砖,该砖具有良好的抗热震性、耐高温性、耐磨性,是水泥回转窑过渡带的理想耐火材料。
本发明可以通过以下技术方案实现:一种红柱石-莫来石-碳化硅砖,包括以下重量百分含量的组分制备而成:
其中,所述的M70烧结莫来石中Al2O3重量百分含量≥70%;
所述的红柱石中Al2O3重量百分含量≥58%;
所述的碳化硅纯度为97%以上;
所述的硅微粉的主要成分SiO2的含量≥92%;,粒度<1μm;
所述的α氧化铝微粉的主要成分Al2O3的含量≥99%,粒度<5μm;
本发明还提供了一种红柱石-莫来石-碳化硅砖的制备方法。
一种红柱石-莫来石-碳化硅砖的制备方法,包括以下步骤:
(1)混炼:按照配比称取上述组分,外加入总组分重量3~5%的纸浆废液,混炼制成泥料;
(2)成型:泥料置于430t级摩擦压砖机内压制成型制得砖坯;
(3)干燥:将压制成型的砖坯在干燥窑内于100~150℃下干燥24h以上;
(4)烧成:将干燥后的砖坯在以天然气为燃料的高温隧道窑内进行烧制,烧制温度1350~1450℃,烧制时间为70~80h得到红柱石-莫来石-碳化硅砖。
步骤(1)中所述纸浆废液为市售,比重为1.3~1.5g/cm3。
本发明的有益效果:
(1)以红柱石及M70烧结莫来石为主要原材料,比以特级矾土熟料为骨料制成的产品更具备莫来石制品的高温稳定性。红柱石高温下莫来石化后可以在基质形成网状的莫来石结构,且分解生成的高硅氧玻璃相高温下能填充热震产生的裂纹,使材料具有良好的热震稳定性及高温性能。
(2)原料中增加了碳化硅的配比,碳化硅在高温烧制过程中能在砖体表面氧化生成致密的SiO2,该层起到有效的保护作用,能够显著提高产品的耐碱侵蚀性。另外,碳化硅耐磨性能极佳,增加碳化硅比重有利于提高制品的耐磨性能。
(3)与硅莫红砖及镁铝尖晶石砖相比较,本产品具有更加优良的抗热震性、耐高温性、耐磨性,能够广泛应用于水泥窑过渡带。
