摘要洛阳理工学院毕业论文PAGEIV毕业论文镁碳砖的制备与应用摘要镁碳砖是国际上新兴的耐火材料产品，镁碳砖具有高耐火性,良好的抗热震性、抗剥落、抗渣性。它的使用延长了炉衬的使用寿命，是一种广义的新型节能材料，各国都在大力开发镁碳砖生产技术。但是在生产中仍存在易层裂、韧性差等问题。调整镁碳砖配合料颗粒级配、控制混合料湿度与优化压制过程等措施可以提高生产质量。本文开端探讨了镁碳砖的制备。包括原料的选用，意在着重说明原材料的质量性能对镁碳砖使用效果有较大影响。并介绍了生产工艺流程上主要工艺参数的确定及生产过程中镁碳砖的层裂问题及解决方法。随之重点介绍了镁碳砖在转炉上的应用重点阐述了使用环境对其使用效果的影响。在论文末章介绍了镁碳砖在技术上的发展趋势。关键词：颗粒级配，转炉，层裂,镁碳砖PREPARATIONANDAPPLICATIONOFMAGNESIAABSTRACTMagnesiarefractoriesisinternationallyemergingproducts,magnesiawithahighfireresistance,goodthermalshockresistance,spalling,slagresistance.Itsuseextendsthelifeofthelining,isabroadnewenergy-savingmaterial,countriesarevigorouslydevelopingmagnesiaproductiontechnology.However,therearestilleasilyintheproductionofspallation,andpoortoughness.Adjustmagnesiabatchparticlesizedistribution,humiditycontrolandoptimizationofmixturepressingprocessandothermeasurestoimproveproductionquality.Beginningofthisarticlediscussesthepreparationofmagnesia.Includingtheselectionofrawmaterials,intendedtohighlightthequalityoftherawmaterialsusedmagnesiaeffectonperformancehaveagreaterimpact.Anddescribesthemainprocessparametersontheproductionprocessandtheproductionprocesstodeterminethespallmagnesiaproblemsandsolutions.Bricksalongwithhighlightsontheapplicationoftheconverterfocusesontheuseofenvironmentaleffectofitsuse.PaperpresentedattheendofchapterBricksintechnologytrends.KEYWORDS:particlesizedistribution,converter,spall,magnesia前言目录TOC\o"1-3"\h\z\uHYPERLINK\l_Toc23317前言PAGEREF_Toc233174HYPERLINK\l_Toc4174第1章原料的选用PAGEREF_Toc41745HYPERLINK\l_Toc326941.1镁砂PAGEREF_Toc326945HYPERLINK\l_Toc54931.2石墨PAGEREF_Toc54936HYPERLINK\l_Toc135041.3结合剂PAGEREF_Toc135047HYPERLINK\l_Toc204751.4添加剂PAGEREF_Toc204757HYPERLINK\l_Toc744第2章镁碳砖制备PAGEREF_Toc7448HYPERLINK\l_Toc195742.1镁碳砖主要生产工艺参数的确定PAGEREF_Toc195748HYPERLINK\l_Toc143962.1.1镁砂颗粒级别的确定PAGEREF_Toc143968HYPERLINK\l_Toc34002.1.2泥料混练PAGEREF_Toc34009HYPERLINK\l_Toc122832.1.3成型
