| 1 | 浸入式水口渣线ZrO2-C材料的侵蚀机制?显示文摘通过观察损毁样品的侵蚀和渗透情况,研究浇铸TRIP钢时保护渣对ZrO2-C渣线材料的侵蚀机制。ZrO2及其稳定剂CaO的侵蚀溶解是渣线材料侵蚀的决定因素。氧化是石墨损毁的主要方式,石墨在钢水里的溶解对其损毁不起重要作用。ZrO2溶解量和石墨氧化量的比值随着热面到钢水垂直距离的减少而减少。然而,与其他炼钢用碳结合耐火材料不同,在本研究的特殊情况下,石墨被保护渣浸润,它仍然充当耐火成分,但仅部分作为抗渣渗透剂。渣渗透后,ZrO2开始被侵蚀,降低了抗渣侵蚀性,然而渣中成分的气相传输可能导致CaO在未渗透区域脱溶。 | Harald Harmuth Nathalie Kolbl Barbara Rollinger Guangmin Xia | 2013 | 耐火材料2013，，3： | 2 |
| 2 | Corrosion Mechanisms of SEN Slagband Materials显示文摘Wear of a zirconia graphite slagband material by mold slag during casting of a TRIP steel grade was investigated on worn specimens with respect to corrosion and erosion.Corrosion dissolution of both the stabilizer oxide and the zirconia is decisive.Oxidation is dominating graphite wear whereas a possible dissolution in the liquid steel was not observed to play an important role here.The ratio of oxide corrosion to graphite oxidation decreases with decreasing vertical distance of the hot face to the steel bath.Unfortunately and contrary to other applications of carbon bonded refractories in steel industry graphite exhibits to be wetted by mold slag in the special case investigated here,it still acts as a refractive component, but only partly as an infiltration inhibitor.Infiltration is followed by zirconia corrosion thus reducing erosion resistance,but nevertheless also gas phase transport of slag components may cause exsolution of the stabilizer oxide in un-infiltrated regions. | Harald HARMUTH Nathalie KBL Barbara ROLLINGER Guangmin XIA | 2013 | China's Refractories2013，22，2： | 1 |
