Description

一种中频炉修补料
技术领域
本发明涉及一种中频炉炉衬的修补料，属于中频炉用耐火材料技术领域。
背景技术
中频炉具有熔化速度快、生产效率高、使用灵活、污染小、电磁搅拌效果好和高效节能等特点，近年来被广泛的应用于不锈钢、特钢和铸造行业，并且不断向大功率、快速熔化和大容量方向发展。中频炉炉衬材料是中频炉的重要组成部分，在中频炉熔炼过程中，由于受到金属熔体和熔渣的侵蚀及频繁的温度变化所带来的热冲击，炉衬局部会出现裂纹或剥落的情况。修补用可塑料涂覆在裂纹或剥落的部位，可形成与炉衬结合为一体的修补层，以提高炉衬的使用寿命和减少耐火材料的消耗。
中频炉炉衬以刚玉（矾土）-尖晶石质捣打料应用最为广泛，修补刚玉（矾土）-尖晶石质捣打料炉衬时用的可塑料，要求具有粘结性强、耐高温、抗热震和耐冲刷等特点。目前，常见的修补用可塑料主要存在问题：1）粘结性较差，修补时易脱落；2）常温硬化慢、早期强度低；3）修补后使用寿命短；4）保存时间短；5）不易施工、修补时工作效率低；尤其是保存期短，极大地影响了修补用可塑料的使用。
发明内容
本发明的目的在于克服现有技术存在的不足，而提供一种有良好热态修补性能，可随补随用，较好地解决中频炉使用过程中出现裂纹、影响其正常使用的中频炉修补料。
本发明的目的是通过如下技术方案来完成的，一种中频炉修补料，所述的修补料由如下组分组成：
三氧化二铝主料 65-75%，
三氧化二鉻 10-16%，
硼砂 3-10%，
高温粘结剂 2-8%，
钛白粉 1-3%，
硅微粉 2-5%，
以上各组分的重量百分配比以100%为准。
作为优选：所述的修补料由如下组分按重量百分比组成：
三氧化二铝主料 70%，
三氧化二鉻 13%，
硼砂 6.5%，
高温粘结剂 5%，
钛白粉 2%，
硅微粉 3.5%，
所述的三氧化二铝主料由刚玉与矾土按照4-6：4-6的比例组成。
本发明具有良好热态修补性能，可随补随用，较好地解决中频炉使用过程中出现裂纹、影响其正常使用等特点。
具体实施方式
