naiya qiongdu耐压强度(erushing strength)衬火材转在一定温度下,单位面积上所能承受的极限载荷。耐压强度是衡量耐火材料质量的重要性能指标之一,间接地反应出制品的组织结构,如致密性、均匀性、烧结性等。通常分为常温耐压强度和高温耐压强度。常温耐压强度是指制品在室温下测得的数值;将试样加热至某一指定温度进行加压试验,所取得的结果称为该温度下高温耐压强度。 制品耐压强度的高低主要取决于自身的材质类别,但制造工艺水平对耐压强度值有很大影响。 中国国家标准对不同用途的耐火材料的耐压强度值作了规定。常用致密耐火制品的常温耐压强度值(MPa)如下:高炉用粘土砖大于49.0,热风炉用拈土砖大于19.6,玻璃熔窑用大型粘土砖大于34.3,一般用途高铝砖大于49,o,热风炉高铝砖大于39.2;电炉盖用高铝砖大于58.8,焦炉硅砖大于19.6;玻璃熔窑用硅砖大于24.5,普通镬砖大于39.2,平炉用镁铝砖大于29.4;镁格砖大于24.5。测定常温耐压强度的方法,中国国家标准《致密定形耐火制品常温耐压强度试验方法》(GB5072)规定,从耐火制品上切取正方体或圆柱体试样,在压力试验机上,按规定的加压速率,对试样加压,直至其破坏,记录最大压力值,计算出单位面积承受的压力,单位MPa。测定不定形耐火材料的耐压强度时,必须先按试样制备方法的标准规定制备试样。测定高温耐压强度时,压力试验机应附设高温加热炉。试样在炉内按规定升温速率加热,到达规定温度,并保温一定时间后,对试样加压,直至其破坏,其余与测定常温耐压强度方法相同。国际标准《致密定形耐火制品—常温耐压强度的测定》第1部分:无衬垫仲裁试验(150 10059一1),与中国标准GB5o72主要差异为试验时,试验机加压板与试样之间,不准加衬垫.对于定形隔热耐火制品常温耐压强度的测定,中国标准GB3997·2与国际标准1508895等效。 (王适荣)
