Description
技术领域
本发明属于浸入式水口技术领域，具体涉及一种浸入式水口及制备方法。
背景技术
浸入式水口是一种金属连罐铸造用上接中间包上水口下连结晶器部位，属于金属铸造熔融物输送部件，是金属连续铸造一次性使用的耐火材料部件。是连续生产钢水最后接触的耐火材料，也是在连铸工艺中最关键，研发最高地功能耐火材料，上接中间包下连结晶器，将钢水输送到结晶器，并保护钢水不发生二次氧化，防止氮溶入或渣混入钢水，影响钢坯质量。特别是在浇铸合金钢、高碳钢时，与中包上水口配合处密封尤为重要，连铸生产中比较重视浸入水口与上水口配合处密封问题。
现有技术中的浸入式水口常规做法是本体料和渣线料为一种料，由于采用的耐火材料的组成与组分不尽合理，致使产品的耐高温、抗热震性能不够好，抗侵蚀、热冲击强度不够高，抗剥落性能不佳，造成浸入式水口产品使用寿命短，机械强度低、材质剥落导致钢水掺杂、铸坯质量不合格，而且生产成本高。
发明内容
为解决上述问题，本发明提供如下技术方案：包括本体和渣线，所述本体按重量百分比如下：
棕刚玉36＃ 10-20%
棕刚玉80＃ 10-20%
棕刚玉180＃ 20-40%
石英 5-10%
石墨195 10-20%
石墨895 5-10%
添加剂 5-10%
结合剂 10%-15%
所述渣线按重量百分比如下：
钙稳定氧化锆24＃ 10-20%
钙稳定氧化锆40＃ 10-20%
钙稳定氧化锆100＃ 10-20%
钙稳定氧化锆325＃ 30-50%
石墨195 5-10%
添加剂 5-10%
结合剂 5-10%。
进一步的，所述本体优选的重量百分比为：
棕刚玉36＃ 15%
棕刚玉80＃ 15%
棕刚玉180＃ 25%
石英 5%
石墨-195 15%
石墨895 10%
添加剂 5%
结合剂 10%
所述渣线优选的重量百分比为：
钙稳定氧化锆24＃ 15%
钙稳定氧化锆40＃ 15%
钙稳定氧化锆100＃ 15%
钙稳定氧化锆325＃ 40%
石墨195 5%
添加剂 5%
结合剂 5%。
本发明发提供了以上方案所述的一种浸入式水口的制备方法，包括以下步骤；
S1、配料；将浸入式水口本体和渣线依照各自配方按重量百分比进行配比；
S2、混料；将浸入式水口本和渣线原料分别放入各自混炼机中进行充分混合均匀，得到泥料；
S3、挥发；将泥料在60℃下烘干至挥发分为0.8-1.4%；
S4、困料；将泥料恒温静置12-24小时；
S5、装料压制；将烘干后的泥料加入到各自的模具中，通过等静压机压制成型；
S6、烘干；将压制成型后的样品在200℃下烘烤24小时；
S7、烧成；将样品进行真空烧成，烧成温度为1050℃；
S8、抽检；将烧成后的样品进行探伤检测；
S9、二次烘干；对检测后没有问题的样品涂抹抗氧化层，并进行二次烘干；
S10、成品入库；二次烘干冷却后，粘贴陶瓷纤维纸并包装入库。
进一步的，所述步骤S2中混炼机的温度为30-60℃。
进一步的，所述步骤S5泥料经压力为100～120Mpa等静压机压制成型。
本发明提供的一种浸入式水口，本体采用棕刚玉颗粒作为本体材料骨料，其致密度、抗侵蚀性和均匀度优异，石墨韧性好，物理化学性能优，具有良好的耐高温，自润滑、传导、抗热震、耐腐蚀等多种性能，材料经配制、摩压成型、高温烧结工艺制成，形成了良好的β-SiC和α-Al2O3网络陶瓷结合，提高了材质结合强度，增强了制品高温使用性能。由于高温烧成后的β-SiC以晶须状充填在砖结构的空隙中，使气孔变小，加强了骨料颗粒之间，骨料颗粒与基质之间的结合，因而提高了材料的强度和耐磨性；本发明的渣线采用钙稳定氧化锆和石墨作为主要材料，渣线的耐蚀性会随着钙稳定氧化锆的含量的增加而增加，但是，钙稳定氧化锆的导热系数低，其热膨胀后会增加浸入式水口熔渣带产生剥落的可能性，虽然石墨的含量增加会提高的抗热剥落性能，但是其耐火度欠佳，研究人员研究发现，钙稳定氧化锆的重量百分比超过80%，在标准预热情况下，浸入式水口容易产生剥落，但是在钙稳定氧化锆重量百分比达到85%时，浸入式水口却不易产生剥落，使得材料的抗剥落性得到较好的提升，同时降低了石墨的含量，使得材料的耐火度得到了保证。
本发明提供了一种浸入式水口的制备方法，其中困料时间为12-24小时，适当延长困料时间有利于混合料互相结合地更均匀些，充分发挥结合剂的可塑性能和结合性能，以改善坯料的成型性能，配合特定的工艺，使得本产品具有优秀的热震稳定性能，使得浸入式水口的使用寿命大大延长。
