抗折强度
bending strength
kangzhe qiangdu抗折强度(bending strength)材料单位面积承受弯矩时的极限折断应力。又称抗弯强度、断裂模量。颗粒配比是否合理、气孔的大小和数量、组织结构是否均匀一致、颗粒间结合是否牢固等是决定耐火材料抗折强度大小的重要因素.提高衬火材朴的抗折强度,主要工艺手段是:改进砖料的颗料级配、加大成型压力以提高制品坯体的密度,使用优质结合剂和提高制品的烧结程度。 室温下测定的抗折强度称为常温抗折强度;当材料预先加热至某一温度并保温一定时间(通常为30min)进行抗折试验,所得强度值称为该温度下的高温抗折强度,也称热态抗折强度。(见彩图插页第n页) 在所有耐火材料中,用作转炉炉衬的镁破砖和不定形衬火材并,高温抗折强度是衡量其性能的不可缺少的指标。 测定抗折强度,中国标准《耐火制品常温抗折强度试验方法》(GB3。。1),《耐火制品高温抗折强度试验方法》(GB 3002),《铸锭用绝热板常温抗折强度试验方法》(Z BQ 45005),其要点是:从被测制品上切取断面为正方形的长条试样,在抗折试验仪上进行试验,见图。 李L士2阵弃王 抗折试验装置原理图按下述公式计算抗折强度: ~3 FL、,~ 凡=份三于苍,MPa 一,Zb尸’一’-一式中R。为试样抗折强度,MPa;F为试样折断时最大载荷,N;L为下刀口之间距离,mm;b为试样断面宽度,mm;h为试样断面高度,mm。 测定易氧化材料的高温抗折强度时,加热炉内应充中性或还原性气体,或用碳质材料将试样搜盖,以避免试样氧化。 (王通荣)
