Description

一种浸入式水口板间密封材料及其制备方法
技术领域
本发明涉及钢铁冶金连铸技术领域，更具体的说是涉及一种浸入式水口板间密封材料及其制备方法。
背景技术
连铸三大件的透气上水口以及浸入式水口使用时，该两种产品配合时，由于产品加工问题，或钢厂硬件问题，造成两种产品结合面出现缝隙，引起板间无背压，吸气造成水口扩孔提前下线，对现场生产节奏造成困扰。更严重的情况为钢坯指标不合格，造成经济损失等问题。
因此，结合上述问题，提供一种降低板间缝隙出现的浸入式水口板间密封材料及其制备方法，是本领域技术人员亟需解决的问题。
发明内容
有鉴于此，本发明提供了一种浸入式水口板间密封材料及其制备方法。
为了实现上述目的，本发明采用如下技术方案：
一种浸入式水口板间密封材料，按重量份原料为：硅酸钠粉20～40份、200目金属铝粉5～10份、-195石墨25～30份、球状黏土8～15份、氧化铝微粉8～15份、经过处理的膨胀石墨粉1～10份、水15～40份；
其中，经过处理的膨胀石墨粉的制备方法为：在80-150倍的低膨胀率的1～10份的膨胀石墨粉中，加入3～10份浓度≥99％的糠醛溶液，充分搅拌后100℃烘干；冷却后加入3-10份硅溶胶，充分搅拌后烘干；再加入3-10份糠醛，充分搅拌后烘干得到经过处理的膨胀石墨粉。
一种浸入式水口板间密封材料的制备方法，按上述的配比称取原料，将除水以外的所有原料混合后，再加入水混合均匀，得到状态为粘稠胶状的浸入式水口板间密封材料。
优选的，所述粘稠胶状的浸入式水口板间密封材料在实施中，在板面涂抹后厚度为2-5mm，相对抹平后，放入干燥窑干燥，干燥温度为100℃～250℃，从干燥窑取出后，进行抛光至所需高度。
通过采用上述优选方案，本发明的有益效果在于：
本发明利用膨胀石墨的膨胀特性，降低板间缝隙的出现，从而减低事故的发生，减低钢厂次品的发生几率。替代原有板面的润滑剂，厚度的增加会提升水口滑动的效率，减少板间缝隙出现几率，进而产生板间吸气的可能。
具体实施方式
下面对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
实施例:
使用处理后的膨胀石墨制作产品并且试验，试验数据如下,
结论如下：
处理膨胀石墨过程中发现，处理过的膨胀石墨以及硅溶胶不变的情况下，随着糠醛溶液的增加膨胀率有明显的降低，推断为糠醛溶液对石墨的润湿情况起了很大的效果。
同种处理后的膨胀石墨份数的增加，膨胀率会有一定程度的增加。
对所公开的实施例的上述说明，使本领域专业技术人员能够实现或使用本发明。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的，本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下，在其它实施例中实现。因此，本发明将不会被限制于本文所示的这些实施例，而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
