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)
