Description
技术领域
本发明涉及耐火材料技术领域,具体为一种电炉炉底捣打料。
背景技术
捣打料是指用捣打(人工或机械)方法施工,并在高于常温的加热作用下硬化的不定型耐火材料。由具有一定级配的耐火骨料、粉料、结合剂、外加剂加水或其他液体经过混炼而成。按材质分类有高铝质、粘土质、镁质、白云石质、锆质及碳化硅-碳质耐火捣打料。
捣打料的导热系数较低,不利于高炉炉体的快速冷却,从而影响了使用寿命,为此本发明提出一种新型的解决方案。
发明内容
本发明的目的在于提供一种电炉炉底捣打料,以解决上述背景技术中提出的问题。
为实现上述目的,本发明提供如下技术方案:一种电炉炉底捣打料,由以下重量份的原料制成:氧化镁:60;氧化钙:30;氧化铁:8;回收铝镁碳砖颗粒:6;氧化铝:2;二氧化硅:2;结合剂:4-5。
更进一步地,所述氧化镁的粒度为:0.1-2mm;氧化钙的粒度为:1-3mm;氧化铁的粒度为:2-5mm;回收铝镁碳砖颗粒的粒度为:2-5mm;氧化铝的粒度为:5-10mm;二氧化硅的粒度为:1-3mm。
更进一步地,所述结合剂使用的是的MgCl2.6H2O加水稀释成比重为1.2-1.3的卤水。
一种电炉炉底捣打料的制备方法,包括以下步骤:
S1:对回收铝镁碳砖进行破碎处理;
S2:对破碎后的回收铝镁碳砖进行筛选过滤,得到高纯度的回收铝镁碳砖颗粒;
S3:将回收铝镁碳砖颗粒放入水中浸泡30-40小时;将浸水后的回收铝镁碳砖颗粒送入干燥炉中进行干燥,温度控制在150-180摄氏度使得回收铝镁碳砖颗粒的残余水分小于1.15%;
S4:将步骤S3中得到的回收铝镁碳砖颗粒、氧化镁、氧化钙、氧化铁、氧化铝、二氧化硅和结合剂按照所述比重放入回转窖重烧,回转窖重烧温度在1745摄氏度。
更进一步地,所述步骤S1中利用粉碎机进行破碎处理,破碎颗粒粒度在0-10mm。
更进一步地,所述步骤S2中筛选过滤留下颗粒粒度在2-5mm的回收铝镁碳砖颗粒。
与现有技术相比,本发明的有益效果是:
该电炉炉底捣打料,通过在原料中添加废弃铝镁碳砖颗粒,一方面使得捣打料层在工作温度升高时,达到与炭砖、冷却壁相匹配的导热系数,以保证热传导的通常,不损坏其整体的施工结构,从而达到提高高炉寿命的要求,另一方面对废弃的铝镁碳砖加以利用,减少了资源的浪费以及环境污染。

实施例六:一种电炉炉底捣打料,由以下重量份的原料制成:氧化镁:60;氧化钙:30;氧化铁:8;回收铝镁碳砖颗粒:11;氧化铝:2;二氧化硅:2;结合剂:5。氧化镁的粒度为:0.1-2mm;氧化钙的粒度为:1-3mm;氧化铁的粒度为:2-5mm;回收铝镁碳砖颗粒的粒度为:2-5mm;氧化铝的粒度为:5-10mm;二氧化硅的粒度为:1-3mm,结合剂使用的是的MgCl2.6H2O加水稀释成比重为1.2的卤水。
一种电炉炉底捣打料的制备方法,包括以下步骤:
S1:对回收铝镁碳砖进行破碎处理,利用粉碎机进行破碎处理,破碎颗粒粒度在0-10mm;
S2:对破碎后的回收铝镁碳砖进行筛选过滤,得到高纯度的回收铝镁碳砖颗粒,筛选过滤留下颗粒粒度在2-5mm的回收铝镁碳砖颗粒;
S3:将回收铝镁碳砖颗粒放入水中浸泡35小时;将浸水后的回收铝镁碳砖颗粒送入干燥炉中进行干燥,温度控制在160摄氏度使得回收铝镁碳砖颗粒的残余水分小于1.15%;
S4:将步骤S3中得到的回收铝镁碳砖颗粒、氧化镁、氧化钙、氧化铁、氧化铝、二氧化硅和结合剂按照比重放入回转窖重烧,回转窖重烧温度在1745摄氏度。
通过回收铝镁碳转颗粒的重量份数计算出其重量比,然后对各个实施例得到的捣打料进行抗折强度和导热性进行检测,得到下表
由此表可知,当捣打料原料中的回收铝镁碳转颗粒的重量比约为4-5%时,制成的捣打料具有较高抗折强度的同时也有比较不错的导热系数。
尽管已经示出和描述了本发明的实施例,对于本领域的普通技术人员而言,可以理解在不脱离本发明的原理和精神的情况下可以对这些实施例进行多种变化、修改、替换和变型,本发明的范围由所附权利要求及其等同物限定。
