技术领域
本发明涉及炼钢电炉的出钢槽浇注料,以及该出钢槽浇注料的制造方法和使用方法技术领域,具体为一种用于炼钢电炉出钢槽的浇注料及其制备方法。
背景技术
出钢槽是炼钢设备系统中的一个重要组成部份,出钢槽在使用过程中承受着高温钢水的间歇冲刷,为延长出钢槽的使用寿命,要求出钢槽用耐火材料具备良好的抗热震稳定性,耐钢水冲刷性和抗熔渣的侵蚀性,我国炼钢电炉、炼钢平炉出钢槽,过去通常用粘土砖和普通高铝砖砌筑,使用寿命低,钢水对砖缝侵蚀严重,后来改用矾土水泥和水玻璃结合的耐火混凝土整体槽,使用寿命有所增加,但仍不理想,往往表现为不耐钢水冲刷、抗渣侵蚀性能差,而且粘渣严重,远远不能适应当前日趋苛刻的炼钢条件。
发明内容
(一)解决的技术问题
针对现有技术的不足,本发明提供了一种用于炼钢电炉出钢槽的浇注料及其制备方法,具备抗钢水冲刷、抗侵蚀、热震稳定性优良等优点,解决了传统通常用粘土砖和普通高铝砖砌筑,使用寿命低,钢水对砖缝侵蚀严重的问题。
(二)技术方案
为实现上述抗钢水冲刷、抗侵蚀、热震稳定性优良的目的,本发明提供如下技术方案:一种用于炼钢电炉出钢槽的浇注料,包括以下重量份数配比的原料:特级矾土熟料颗粒60-72份、红柱石粉5-20份、碳化硅粉5-10份、α-氧化铝粉3-10份、石墨微粉5-10份、硅微粉4-8份、铝酸盐水泥4-10份、抗氧化剂2-10份、分散剂0.1-0.5份。
优选的,所述抗氧化剂包括有金属硅粉和金属铝粉。
优选的,包括以下重量份数配比的原料:所述特级矾土熟料中铝的含量大于85.0%,红柱石粉中铝的含量大于等于55%,CA-70水泥中铝的含量大于70%。
优选的,包括以下重量份数配比的原料:所述特级矾土熟料中铝的含量大于85.0%,红柱石粉中铝的含量大于等于55%,CA-70水泥中铝的含量大于70%。
本发明要解决的另一技术问题是提供一种用于炼钢电炉出钢槽的浇注料制备方法,包括以下步骤:
1)按比例将特级矾土熟料颗粒、红柱石粉、碳化硅粉、α-氧化铝粉、石墨微粉、硅微粉、铝酸盐水泥和抗氧化剂分散剂混合在一起,干混1分钟,然后快速搅拌,边搅拌边加水,2分钟后稍停,清理粘附在搅拌叶片上及筒壁上的泥料,再次搅拌2分钟,总搅拌时间为5分钟。
2)将步骤1)中搅拌后的浆料出锅,倒入事先固定于振动台的模具中,直至模具上边缘,启动振动台,边振动便填装浆料。
3)停止振动,用刮刀去除高于模具边缘的浆料,并将其表面抹平,整个振动时间控制在60至90秒内。
4)将模置于相对湿度不小于90%,温度20加减1℃的条件下养护,养护24小时后脱模,再在相同条件下养护24小时。
(三)有益效果
与现有技术相比,本发明提供了一种用于炼钢电炉出钢槽的浇注料及其制备方法,具备以下有益效果:
1、该用于炼钢电炉出钢槽的浇注料及其制备方法,通过将特级高铝矾土熟料作为主要原料,其具备结构致密、高温体积稳定性好、耐火度高的特点,为制造出钢槽的浇注料提供了极大的便利,通过配入有适量的碳化硅、碳质材料,将碳化硅中硅的含量设置为大于百分之九十,由于碳化硅导热性好,且切削能力强,进一步增大了切削硬度,通过添加有烧结剂、分散剂,且采用铝酸钙水泥结合,能够促进烧结,帮助燃烧,使其燃烧更加充分。
2、该用于炼钢电炉出钢槽的浇注料及其制备方法,将抗氧化剂主要由金属硅粉和金属铝粉组成,金属硅粉能够提高耐高温,耐磨损和抗氧化性,金属铝粉粘附性好,不易分离,且金属硅粉和金属铝粉广泛存在,实用性高,用途广,避免了增加额外的生产成本,通过将模置于相对湿度不小于90%,温度20加减1℃的条件下养护,养护一定时间后能够起到方便脱模的目的,避免由于环境湿度不达标而导致脱模失败,通过添加有α氧化铝粉,该产品具有较高的化学稳定性,纯度高、绝缘性能好,同时也具备耐酸耐碱机械强度大,耐磨、耐冲击力,使得浇注料的抗侵蚀性增强。
