Description

硅钢玉耐磨砖
技术领域
本发明涉及耐火材料，尤其是涉及一种用于砌筑大型水泥回转窑、石灰窑窑体的硅钢玉耐磨砖。
背景技术
目前在大型水泥回转窑、石灰窑的过渡带多采用硅莫砖或抗剥落高铝砖、镁铝尖晶石砖砌筑窑体，其不足之处在于抗热震性和耐磨性能较差，虽然硅莫砖的抗热震性能较其他砖体有所提高，但硅莫砖的热导率较高（高达2.9W/m.K），当用在回转窑过渡带时，可造成窑筒体温度增高（筒体表面温度一般都在350℃~380℃），散热损失大，这样不仅易导致回转窑筒体变形，而且还易引起窑筒体向后膨胀，加大窑尾密封装置的磨蚀损坏；同时还会造成回转窑内衬砖体剥落、破损，掉砖，降低回转窑的使用寿命，从而使生产成本大幅度提高，消耗了燃料、人力及原材料，投入高产出低，企业经济效益受到严重影响。
由于硅莫砖是经1450℃高温烧结而成的产成品，燃料消耗大，制砖成本高，不能达到节能减排降耗的目的。
发明内容
本发明的目的在于提供一种硅钢玉耐磨砖，该砖体制造时无需高温烧结，节能降耗，且具有高强度、高耐磨、高荷软、高热震的性能，由于其导热系数低，用于砌筑回转窑时可大大延长窑体的使用寿命。
为实现上述目的，本发明可采取下述技术方案：
本发明所述的硅钢玉耐磨砖，是由原料特级高铝矾土颗粒料、电熔刚玉颗粒料、碳化硅粉、合成莫来石粉、蓝晶石粉、结合剂、添加剂和外加剂按下述重量份配比烧结而成：
原料配比：
特级高铝矾土颗粒料50～55份，电熔刚玉颗粒料5～10份，碳化硅粉10～15份，合成莫来石粉10～15份，蓝晶石粉5～7份，结合剂2～3份，添加剂3～5份，外加剂为比重1.6 g/cm3的磷酸溶液6～8份；
加工方法为：
首先将特级高铝矾土颗粒料和电熔刚玉颗粒料放入湿碾机中混合均匀，然后加入磷酸溶液继续混碾3~5分钟，最后再加入SiC粉、合成莫来石粉、蓝晶石粉、结合剂、添加剂后，持续混碾10~15分钟出碾，困料20~24小时后，再将物料放入湿碾机中二次混碾10~15分钟，将泥料出碾，在压力机上将混合好的泥料压成砖坯，成型后的砖坯经150~180℃低温干燥15~20小时后再送入隧道窑内进行烧成，砖坯烧成温度600~650℃，保温8～10h，出窑后即为成品砖体。
经检测，本发明生产的硅钢玉耐磨砖成品的理化指标如下：
为保证成品复合砖的质量要求，所述特级高铝矾土颗粒料粒度为0.1~10mm，所述电熔刚玉颗粒料的粒度为.01~5mm，所述合成莫来石粉料和碳化硅粉料的粒度为200目，所述蓝晶石粉料的粒度为100目。所述结合剂为粒度200目的黏土粉料，所述添加剂为金属硅粉和锆硅微粉按45:55的重量份配制的混合粉料，其中金属硅粉的粒度为200目，锆硅微粉的粒度为10um。
实际生产时，本发明硅钢玉耐磨砖所用原料的重量份配比可以为：特级高铝矾土颗粒料50份，电熔刚玉颗粒料 10份，碳化硅粉15份，合成莫来石粉15份，蓝晶石粉5份，结合剂2份，添加剂3份，比重1.6 g/cm3的磷酸溶液6～8份。
所述原料的重量份配比还可以为：特级高铝矾土颗粒料55份，电熔刚玉颗粒料10份，合成莫来石粉10份，蓝晶石粉7份，SiC粉10份，结合剂3份，添加剂5份，比重1.6 g/cm3的磷酸溶液6～8份。
所述原料的重量份配比也可以为：特级高铝矾土颗粒料53份，电熔刚玉颗粒料9份，合成莫来石粉13份，蓝晶石粉6份，SiC粉13份，结合剂2份，添加剂4份，比重1.6 g/cm3的磷酸溶液6～8份。
本发明硅钢玉耐磨砖以特级高铝矾土熟料和电熔刚玉为骨料，以合成莫来石粉、蓝晶石粉、SiC粉和结合黏土为基质，并加入了金属硅粉和锆硅微粉添加剂，利用锆硅微粉细小的粒径以及锆在一定温度下与氧化铝发生反应，形成莫来石和斜锆石，大大提高了砖体的抗热震性和耐剥落性，使砖体在回转窑内长期工作不剥落、不破损、不抽签掉砖，同时在原料中加入微粉还可以在烧成过程中产生大量的纳米级的封闭气孔，有效降低了砖体的热导率和气孔率，大大提高了砖体的烧结强度和耐磨性，同时使回转窑筒体温度较原有筒体温度降低了60～100℃，从而可以大幅度延长了回转窑的运行寿命，其优越性远超硅莫砖、抗剥落高铝砖等高温烧结的砖体，是新一代水泥回转窑、石灰窑更为理想的节能窑衬。
本发明的硅钢玉耐磨砖是在低温（600~650℃）下烧制而成的产品，其耐磨性、热震稳定性、抗侵蚀性、低导热性等各项性能指标及使用效果均优于高温烧结的硅莫砖、抗剥落高铝砖、镁铝尖晶石砖（砖坯烧成温度1450～1550℃）的性能指标；由于是低温烧制，节约了大量的燃料和能源，大大降低了吨生产制造成本，真正达到了节能降耗的目的，提高了企业的经济效益。以生产同样一吨砖为例，生产一吨本发明的硅钢玉耐磨砖（烧成温度600-650℃）需用天然气30m3，每吨用电量70 度；而生产一吨硅莫砖及其它高温烧结砖（砖坯烧成温度1450～1550℃）需用天然气130 m3，每吨用电量 195度，按现行天然气价格每方2.9元，工业用电平均0.8元/度计算，每吨砖可节约天然气 100 m3，用电量节约125度，保守按每年生产5000吨计算，一年可节约天然气 50万m3，资金145万元，节约用电62.5万度，资金50万元，再加上其它人工工资等费用，经济效益更为客观。
