Description
技术领域
本发明涉及耐火材料技术领域，具体涉及一种高强度复合陶瓷耐磨衬及其制备方法。
背景技术
目前炼铁行业冶炼强度普遍加大，矿槽料仓储运量随之大幅度上升，皮带转速成倍提高，物料进入矿槽料仓时重力加速度对耐磨层表面产生更大的冲击力，同时伴生大量红矿，由此对衬板提出了耐冲击、抗磨损、耐高温的性能要求。特别是皮带机机头机尾落料点，溜槽落料点等受冲击部位，也需要耐冲击、抗磨损、耐高温的性能要求。传统使用的陶瓷耐磨喷涂料，可塑性强硬度较低厚度大，用量大，表面不平滑，易造成堵料，使用寿命不超过3年；传统的耐磨浇注料，落渣点的位置难以解决，浇注料不抗烧、不抗冲砸，少量的出红渣，会引起耐磨层表层烧焦，整体耐磨层会快速剥落，而且锚固件上浇注，耐磨层毁坏后，只能频繁涂抹维修，维护周期较长。
发明内容
本发明的目的是提供一种高强度复合陶瓷耐磨衬及其制备方法，本发明的复合陶瓷耐磨衬耐冲击耐磨性能更加优越，最大限度地适应冶炼强度高的生产状况，且能够延长使用寿命。
本发明为实现上述目的所采用的技术方案为：高强度复合陶瓷耐磨衬，包括衬体，该衬体为具有阴阳接口的预制体，预制体由基体和包裹在基体外的耐磨体组成，所述的耐磨体由氧化铝粉、广西白泥、水、ρ-Al2O3和分散剂组成，各原料的重量百分比为：氧化铝粉90-95%、广西白泥4.5-9.5%，余量为水和ρ-Al2O3，分散剂的重量占原料总重量的百分比是0.5-1.1%；所述的基体由红柱石、氧化铝粉、铝粉、碳化硅纤维和分散剂组成，各原料的重量百分比为：红柱石80-90%、氧化铝粉5-10%、铝粉4-6%、碳化硅纤维1-4%，分散剂的重量占原料总重量的百分比是0.5-1.1%。
本发明中，氧化铝粉和广西白泥的粒径均为800目。
本发明的分散剂为三聚磷酸钠和/或六偏磷酸钠。
高强度复合陶瓷耐磨衬的制备方法，包括以下步骤：步骤一.取基体的原料红柱石、氧化铝粉、碳化硅纤维混合后放入球磨机研磨，然后均分为等量的两份，在其中一份中加入余量的铝粉，将未加铝粉的原料装入预先准备的模具中，压制成型预制件A；
步骤二.取耐磨体的原料混合后放入球磨机研磨，达到2000目，加入到压力机，抽真空，成型预制件B；
步骤三.将预制件B置于预制件A之外，将加入铝粉的原料经过熔炼为半固态后填充至预制件A与预制件B之间，冷却后，500-600℃烘干排出水分后，1500-1600℃烧结制成预制件。
本发明耐磨体中：白泥的加入量少，由水化结合的ρ-Al2O3补充，白泥的主要化学成分：Al2O3 18%、SiO2 72%、K2O 5.7%、Na2O 0.11%、Fe2O3 0.7%，与白泥复合，可起到叠加的生坯增强效果，有利于顺利脱除模芯。
ρ-Al2O3属水化结合，煅烧后形成α-Al2O3，不带入杂质，不会影响预制件的高温性能。
ρ-Al2O3水化后，生成化学结合水，在500~600℃才能完全排除掉。在水化过程产生凝胶，使材料在受热冷却过程产生的应力降到晶界以下，提高材料的强度和抗开裂能力。
本发明中，白泥能够形成一定的低温液相，促进氧化铝粉烧结，而白泥中部分游离的SiO2与原料中的Al2O3粉发生反应，生成针状的二次莫来石，均匀分布于整个制品中，起到颗粒增韧的作用。本发明的主晶相刚玉，次晶相莫来石，少量玻璃相。
本发明耐磨体的热导率约1.22w/m.k，使使用部位的外表面温度较低，体积密度＞3.0，荷重软化温度1260℃，莫氏硬度7-8级，磨耗约0.3‰/h。
主要采用氧化铝粉90-95%、广西白泥4.5-9.5%混合烧制，白泥和少量的ρ-Al2O3能够作为粘接剂用于增韧氧化铝材料，无需外加结合剂。
本发明基体中：Al2[SiO4]O是红柱石原料的主矿物，在使用加热时生成莫来石Al2O3·2SiO2和高硅氧SiO2玻璃相。红柱石分解为莫来石和高硅氧玻璃，莫来石成网络结构，部分高硅氧玻璃从颗粒内向外迁移，留下很多微孔，微孔可缓冲热应力，阻止裂纹的扩展，部分留在颗粒内高硅氧玻璃也有缓冲热应力的作用，并且高硅氧玻璃还有修复粘合热震裂纹的作用。
红柱石的莫来石化反应的发生，会伴随6%左右的膨胀，可抵消压蠕变时的压缩；所产生的游离SiO2，从红柱石颗粒内迁移出来可与加入的氧化铝粉以及耐磨体中的氧化铝粉发生反应生成莫来石，也同样伴随着体积膨胀，可抵消压蠕变时的压缩，生成的莫来石交错网络结构，也有利于抗蠕变性。
碳化硅纤维对基体内部裂纹的偏转和截止作用，防止了裂纹扩展长大形成网状微裂纹结构，有效提高了制品的抗热震性能和断裂韧性能。
本发明利用基体外包研磨体，（1）提高耐冲击耐磨性能，最大限度地适应冶炼强度高的生产状况，使用寿命延长三倍以上，减少维护频次，保证了设备生产连续性。（2）不仅具有耐磨性能，还具有抗热震抗蠕变性。

高强度复合陶瓷耐磨衬，包括衬体，该衬体为具有阴阳接口的预制体，预制体由基体和包裹在基体外的耐磨体组成。耐磨体由94%氧化铝粉、5.5%广西白泥、0.3%水、0.2%ρ-Al2O3组成，另加：六偏磷酸钠，0.6%。基体由86%红柱石、6%氧化铝粉、6%铝粉、2%碳化硅纤维组成，另加：三聚磷酸钠，1.1%。
高强度复合陶瓷耐磨衬的制备方法，包括以下步骤：
步骤一.取基体的原料红柱石、氧化铝粉、碳化硅纤维混合后放入球磨机研磨，然后均分为等量的两份，在其中一份中加入铝粉，将未加铝粉的原料装入预先准备的模具中，压制成型预制件A；
步骤二.取耐磨体的原料混合后放入球磨机研磨，达到2000目，加入到压力机，抽真空，成型预制件B；
步骤三.将预制件B置于预制件A之外，将加入铝粉的原料经过熔炼为半固态后填充至预制件A与预制件B之间，冷却后，500℃烘干排出水分后，1560℃烧结制成预制件。耐磨体的热导率为1.25w/m.k，磨耗0.21‰/h。
本发明预制件可耐受温度300-450℃，厚度为耐磨浇注料的1/4，故可以相对减轻仓体的负重；满足铁前***对抗磨、耐高温、扛冲击材料的需求，减少维护频次。
