Description

一种再生型镁尖晶石质干式振动料及其制备方法
技术领域
本发明属于耐火材料制造领域,尤其涉及到到一种耐火废弃物回收利用到炼钢用中间包的工作层。
背景技术
水泥窑炉在大修时每年产生大量的废弃耐材,这些耐材大都未能得到良好的处理和利用,甚至出现污染环境的情况。其中镁尖晶石质砖在用后一直没能得到重视和再生利用,造成了不小的浪费。另外镁尖晶石砖在用后仍具有耐压强度高、热震稳定性好、抗热蠕变性能好、抗侵蚀和渗透能力、荷重软化温度高的特点,所以用于炼钢浇注用中间包工作衬成为可能。
目前废弃原料市场中大量囤积了镁尖晶石废砖,价格只有几百元不等,与中包用主要原料烧结镁砂、电熔镁砂比较具有一千到几千元的价格差距空间,但在耐火指标方面,不含碳、含硅较低,无硫、无磷等影响钢水杂质,耐火度与镁砂接近,而且部分性能还要突出。
发明内容
本发明利用回收再生后的镁尖晶石砖颗粒,并磨制部分细粉与部分烧结镁砂配合,重新设计和制造出一种再生型镁尖晶石干式振动料。
本发明提供一种再生型镁尖晶石质干式振动料,该振动料按振动百分比计包括如下组份:
40-60%废镁尖晶石砖回收颗粒料,其临界粒度范围3-0.1mm,
10-20%电熔镁砂颗粒,其临界粒度范围1-0.1mm,
5-10%废镁尖晶石砖回收细粉,其细度≤0.088mm,
15-30%电熔镁砂细粉,其细度≤0.088mm,
0.3-1%硼酸,
1-5%氧化铝微粉,其细度≤0.032mm,
3-4%固体酚醛树脂粉,
0.3-0.8%乌洛托品;
其中,所述废镁尖晶石砖回收颗粒料和废镁尖晶石砖回收细粉经过以下方法得到:将从市场上回收的镁尖晶石废砖进行拣选,拣选出杂物,剥除废砖表面的杂质,然后经过烘烤排出水分,按照耐火材料生产用的破粉碎设备加工出所需粒度的颗粒和细粉备用。
作为优选,所述的废镁尖晶石砖回收颗粒料和细粉中氧化镁的含量62±2%,氧化铝的含量8±2%,主要功能是提高干式料的耐火度,提高抗渣渗透性能,并且在材料中起到支撑作用;作为优选,所述的电熔镁砂颗粒为氧化镁含量为95±2%,主要功能是提高干式料的耐火性能。
作为优选,所述的废镁尖晶石砖回收颗细粉中氧化镁的含量为62±2%,氧化铝的含量8±2%,主要功能是提高干式料的耐火度,并在使用中和镁砂粉产生高温反应,原位生成尖晶石,提高抗渣性能。
作为优选,所述的电熔镁砂细粉为氧化镁含量95±2%,主要功能是提高干式料基质的耐火度。
作为优选,所述的硼酸,H3BO3含量大于99%,主要是促进中温烧结作用。
所述的氧化铝微粉主要是起到中高温促烧作用。
所述的固体酚醛树脂粉是一种结合剂,起到为材料提供强度的作用。
所述的乌洛托品是固体酚醛树脂粉的固化剂。
本发明还提供一种再生型镁尖晶石质干式振动料的制备方法,该制备方法包括如下步骤:先将从市场上回收的镁尖晶石废砖进行拣选,拣选出杂物,剥除废砖表面的杂质,然后经过耐火材料生产用的破粉碎设备加工出所需粒度的废镁尖晶石砖回收颗粒料和废镁尖晶石砖回收细粉,将废镁尖晶石砖回收颗粒料及废镁尖晶石砖回收细粉、电熔镁砂颗粒及细粉、硼酸、氧化铝微粉、固体树脂粉、乌洛托品按上述比例全部投入高速搅拌机内,干混15-20分钟,然后包装即可。现场施工方法同普通中间包干式振动料一样,没有区别。
本发明产生的效果:产品中的原料由于具有较高的耐火性能,所以在使用时抗侵蚀性能良好,抗渣渗透性得到提高,高温下稳定性能好,工作衬使用寿命得到延长,同时产品原料成本价格较低。
