Description
技术领域
本发明涉及耐火材料技术领域,更具体的说是涉及一种耐火型铬质引流剂及其制备方法。
背景技术
为避免钢包水口部位的钢水被冻结，要在钢包水口内填充引流砂。引流砂的作用机理在于：钢水注入钢包的初期，水口上表面的引流砂接触钢水后迅速烧结而阻碍了熔融钢水的渗透，烧结层在下部引流砂的支撑下能够承受钢水的静压力而不破坏；同时引流砂的烧结速度变慢，烧结层保持一定的厚度。而开浇时下部的未烧结的引流砂因自重作用下落，烧结层失去支撑，导致烧结层在钢水的重力作用下破碎，实现开浇。
钛铁合金是生产链条钢等优质钢、电焊条以及电子、军工产品等的重要原料。随着钛铁合金产业的不断发展，随之产生的渣也越来越多。废渣的大量堆积不仅污染环境，而且会造成资源的浪费，随之产生的渣也越来越多。废渣的大量堆积不仅污染环境，而且会造成资源的浪费。在当今大力倡导建设资源节约型、环境友好型社会的大背景下，如何处理好钛铁渣并使之成为一种有用的材料，无疑具有积极的现实意义。钛铝酸钙时在钛铁合金的冶炼过程中产生的副产品，有资料表明，这种副产品的产生量相当大，合金与渣的比例一般都达到1∶1左右。因此如能将钛铝酸钙作为耐火原料使用，不仅带动地方经济，节约耐火材料行业成本还能减少环境污染。
引流砂的自动开浇是引流砂自身性能的重要指标，如果引流砂不能实现自动开浇，则需要采用烧氧方式引流，这不仅损毁滑动水口，还造成部分钢水的二次氧化，影响铸坯质量，而且对操作工人构成安全隐患。钢水不能开浇还会导致中间包液面偏低，甚至连铸生产线被迫中断等现象。为了提高引流砂的自开率，部分厂家采用精选铬矿为主要原料，但是精选铬矿的价格高昂，成本太高，对环境有影响。
发明内容
有鉴于此，本发明提供了一种耐火型铬质引流剂及其制备方法。
为实现上述目的，本发明提供如下技术方案，由以下重量组分构成：氧化铝110份、氧化铬40份、石墨烯20份、结合剂10份、碳化硅15份、钾长石5份、石英砂10份、碳添加剂10份、水0.0025份。
优选的，在上述一种耐火型铬质引流剂及其制备方法中，制备方法如下：
S1：按照重量份数准备好各种原材料；
S2：把氧化铝、钾长石加入搅拌设备中搅拌1-5分钟后，依次加入水、结合剂、碳添加剂，搅拌3-10分钟至钾长石染黑之后，加入氧化铬、结合剂、碳化硅、石英砂、碳添加剂搅拌5-15分钟后出料；
S3：包装、待发包装、待发。
优选的，在上述一种耐火型铬质引流剂及其制备方法中，所述碳添加剂为炭黑和石墨的混合物。
经由上述的技术方案可知，与现有技术相比，本发明公开提供了一种耐火型铬质引流剂及其制备方法，本发明生产的钢包铬质引流剂在使用过程中无有害气体放出，无异味，不产生浓烟，完全能达到规定的环境指标和使用要求，本发明制备方法简单，原料丰富，适合工厂化生产。
