抗CO侵蚀性
carbon monoxide resistance

耐热玻璃管中,加热到450℃保温,通入CO气体,流量为ZL/h,从加热炉的3个窗口,随时观察试样的变化情况。连续通气时间,至少不得少于Zooh,若在此时间内,试样若发生损坏,则试验结束。冷却时,必须以氮气流冲洗耐热玻璃管。试验结果以下列方式表达:(1)试样在450℃暴露于CO气氛中,若干小时未损坏。(2)试样在450℃暴露于CO气氛中,若干小时有碳沉积出现,总共若干小时,试样损坏。并描述每块试样变化的情况。 (余先彬)kangCO qlnshix一ng抗CO侵蚀性(earbonmonoxide resistanee) 耐火材料在CO气氛中抵抗开裂或崩解的能力。耐火制品在40。一600℃下遇到强烈的CO气氛时,由于CO分解,游离C就会沉积在制品上铁点的周围,使制品崩解损坏。高炉冶炼过程中,炉身400一600℃的部位,由于上述原因而使耐火制品开裂和组织结构疏松,是高炉炉衬损毁的重要因素之一。降低耐火制品的显气孔率及氧化铁含量,可以增强其抵抗CO的侵蚀能力。测定抗CO侵蚀的方法,只能做相对的比较。美国《耐火材料在co气氛中崩解试验方法》(AsTMCZss)规定,以20块长22smm、横截面为65m。只65mm或7 6mmX 76mm的试样为一组,分别从10块制品上切取,尽量保留其原砖表面。将装有干燥试样的直径46omm、长914mm的加热室,在氮气氛下加热到495~505℃,试样达到试验温度后,通入co气体改变加热室内气氛,使其至少含有95%的co,按选定的一定时间通气后,检查一次试样。在每次检查之前,用高速氮气流穿过加热室,以彻底冲除co,在冷却期间,保持氮的低速气流。如一组试样中的半数试样,在任一周期的末尾呈现完全崩解时,则该组试验结束。检查各试样的情况,可分为下列4类:(1)未受影响,即没有出现掉粒和裂纹。(2)表面爆裂,即破损造成直径不大于13mm的剥落或表面爆裂。(3)开裂,即破损造成直径大于13mm的剥落或表面爆裂,或两者具有。(4)毁坏,即试样破碎2块或2块以上,或用手一按即碎。英国《抗CO的测定方法》(BS1902:3·10)规定,以2块长70mm、宽50mm、厚50mm的棱柱体,或直径5 Omm、高70mm的圆柱体为一组试样,.分别从两块制品上切取,其中一块从制品的内部切取,另一块要有制品一个原表面。试样放入架在加热炉内一端封闭的
