Description
技术领域
本发明涉及窑炉修补用耐火材料制备技术领域，尤其涉及一种窑炉用的热态修补料及其使用方法。
背景技术
目前众多窑炉内衬采用碳化硅质材料，铝硅系耐火材料，或铝硅系与碳化硅、锆英石、氧化锆、氧化铬等形成的复合材料。窑炉运行过程中，有时会由于多种原因造成炉子内漏气、窜风或漏料，如果停炉修补，会严重影响生产；目前通常采用水基结合、高温固化的修补料，在热态下修补时，投料时修补料即刻发硬，也无法采取其他施工方式进行弥补。
本发明针对上述问题，利用金属熔点低且金属氧化放热反应的特性，发明了一种窑炉干态修补料，只需把原料干态混合均匀，使用时快速投料修补，取得了较好的使用效果。
发明内容
为解决现有技术的不足，本发明提供一种热态修补料及其使用方法，拟解决目前修补料投料时修补料即刻发硬，修补效果差等问题。
为实现以上目的，本发明所采用的技术方案包括：
一种窑炉用的热态修补料，其特征在于，可选自包括以质量分数计的如下组分：5％～20％的金属硅、1％～5％的金属铝、0％～7％的钾长石。
进一步地，所述热态修补料还包括焦宝石、铝矾土熟料、白刚玉、棕刚玉、致密刚玉、板状刚玉、莫来石、红柱石、硅线石、碳化硅、氮化硅、废硅砖砂、锆刚玉、铬刚玉中的一种或几种。
进一步地，热态修补料中各组分的粒度优选均小于等于8mm。
进一步地，所述莫来石的粒度优选小于等于8mm。
进一步地，所述废硅砖砂的粒度优选小于等于2.5mm。
进一步地，所述碳化硅的粒度优选小于等于5mm。
进一步地，所述金属硅粒度优选小于等于0.038mm且质量纯度不低于98％，所述金属铝粒度优选小于等于0.035mm且质量纯度不低于99％，所述钾长石粒度优选小于等于0.106mm。
本发明还涉及一种如上所述的热态修补料的制备方法，包括将所述热态修补料在室温下混合均匀，并防水紧固包装。
本发明还涉及一种如上所述的热态修补料的使用方法，包括如下步骤：
将窑炉降温至800℃～1200℃；
在5～8min内，使用工具将所述热态修补料倒至窑炉待修补部位、布料均匀并拍实。
本发明还涉及一种如上所述的热态修补料的使用方法，包括如下步骤：
将窑炉降温至800℃～1200℃；
用高压氧气泵送所述热态修补料至窑炉待修补部位。
本发明的有益效果为：
采用本发明所述的一种窑炉用的热态修补料及其使用方法，包括加入金属硅、金属铝、钾长石等材料，其余可选性地加入以硅或铝为主要成分的耐火材料，包括焦宝石、铝矾土熟料、白刚玉、棕刚玉、致密刚玉、板状刚玉、莫来石、红柱石、硅线石、碳化硅、氮化硅、废硅砖砂、锆刚玉或铬刚玉中的一种或几种，且该热态修补料制备工艺简单。使用时，先将窑炉降温至800℃～1200℃；然后在5～8min内，使用工具将所述热态修补料倒至窑炉待修补部位、布料均匀并拍实，或用高压氧气泵送所述热态修补料至窑炉待修补部位即可完成修补作业。修补时间短、效率高，且不用停炉，同时可实现修补料与窑炉本体牢固结合，达到封堵、填充等修补作用，防止生产过程中漏气、窜风或漏料等，大大提高窑炉的生产效率和使用寿命。
