Description

一种耐火材料高温抗折测试仪加荷用的载样板及压棒
技术领域
本发明属高温测试仪器部件类,涉及测试耐火材料高温力学性能试验仪施加载荷的机构,特别是涉及一种高温抗折测试仪施加载荷用的载样板及压棒。
背景技术
耐火材料的高温抗折、高温耐压、高温应力应变、压蠕变、荷重软化温度等性能,是其重要的高温力学性能和使用性能。这些高温性能测试仪器的加载机构,分别接触试样的上表面和下表面,由压棒(或称上压棒)和载样板(或称下压棒)组成。试验过程中,在高温、高压的作用下,压棒、载样板必须保持体积稳定,不得与试样发生作用,不能变形。特别是高温抗折仪和以高温折应力为原理的高温应力应变仪,其压棒的施压端部为一条与试样长度方向垂直的直线棱(俗称刀口),其载样板上部与试样接触的是两条与压棒刀口平行的平行刀口;试验(施压)时,仅为三个刀口与试样表面接触,那么,刀口就更不能变形,否则测试就不准确,并且就会缩短压棒和载样板的使用寿命。
专利CN2187307《耐火材料高温抗折强度试验用多功能载样机构》公开了耐火材料高温抗折强度试验用的“载样板用高温强度与热导率较高的氮化硅结合碳化硅制作”。
专利申请CN201310483743.4《一种机压无碳刚玉尖晶石钢包砖及其制备方法》,公开了该钢包砖的物料组成为:
板状刚玉颗粒30~50﹪,
尖晶石颗粒10~20﹪,
板状刚玉细粉10~20﹪,
镁砂细粉1~9﹪,
尖晶石细粉5~15﹪,
硅灰1~10﹪,
氧化铝微粉2~10﹪,
金属Si1~4﹪.
随着冶金工业的发展与进步,镁质(或含镁质)耐火材料的用途、用量不断扩大、增加,碱性耐火材料的性能检测数量也愈来愈大,检测要求愈来愈高;而一直沿用的氮化硅结合碳化硅载样板和压棒,在高温和高压的作用下,因其含有硅(氮化硅、碳化硅),就与镁质(或含镁质)试样发生反应,刀口就会变形,并与试样发生粘结,因而使测试失败,并且造成载样板和压棒报废。而另一现有技术中,也含有硅(硅灰、Si),可以作为钢包砖,但不能作为高温抗折测试仪的载样板和压棒,因其也会与试样发生作用。
发明内容
本发明的目的是克服现有技术与镁质试样发生反应而致变形、粘结的不足,提供一种耐火材料高温抗折测试仪施加载荷用的载样板及
压棒。
本发明的目的可以采用以下技术方案来实现:一种耐火材料高温
抗折测试仪施加载荷用的载样板及压棒,其物料组成按重量百
分比为:
板状刚玉50~85﹪,
氧化铝微粉5~30﹪,
镁铝尖晶石7~30﹪。
结合剂(外加)3~7﹪。
所述的板状刚玉,其颗粒度组成按重量百分比为:
3~1mm25~50﹪,
1~0.5mm13~30﹪,
65目10~25﹪,
325目8~20﹪。
所述的镁铝尖晶石,其颗粒度组成按重量百分比为:
1~0.5mm25~50﹪,
325目50~75﹪。
所述的结合剂,可以是糊精,可以是氮基树脂,可以是聚乙烯醇(PVA)。
所述的上述物料,经混练、成型、烘干、烧成等工序,制成载样板和压棒成品。
本发明的优点:本技术方案的物料为非硅系列,不含硅(碳化硅、氮化硅或硅灰、金属Si),故在试验过程中,在高温、高压的条件下,不与镁质(或含镁质)试样发生作用,因而不会变形,不会粘结。所以,测试结果准确,并且载样板和压棒的使用寿命长。
