查询词典 headwater erosion

MgO-C brick has a good erosion resistance but Al〓O〓-C brick is better. Corrosion mechanism for refractory without carbon is that FeO and oxides of molten slag take place chemical reaction with constituents of refractory and forming low fusing point compounds to be dissolved in molten slag. For those refractory containing graphite carbon is to be decarburized in advance and to form decarburizing layer and metamorphosis layer. The subsequent corrosion is decarburizing and taking chemical reaction to form low fusing point compounds and dissolved in molten slag at the same time.

铁浴中硅和钛的扩散是影响铁浴及熔渣与耐火材料作用的重要因素，耐火材料中添加的TiO〓和SiC受熔渣氧化和侵蚀，将被部分还原形成Si，Ti向铁浴中扩散，Si、Ti在铁浴中的扩散研究结果是： D〓=1.84×10〓exp（－5988.7/T） cm〓/S E〓=49766 J/mol D〓=7.76×10〓exp（－53225.5/T） cm〓/S E〓=442304 J/mol 铁浴式熔融还原熔体对粘土砖，高铝砖，镁砖的侵蚀速度很高，镁碳砖抗侵蚀能力比前几种耐火材料强，但不如铝碳砖；对不含碳耐火材料在熔体中的侵蚀是熔渣中FeO及其它氧化物与耐火材料组分的化学反应形成低熔点物熔蚀进入渣相，产生损毁。
