Description

一种整体塞棒用棒身材料
技术领域
本发明涉及耐火材料制备技术领域,特别是指一种整体塞棒用棒身材料。
背景技术
整体塞棒是冶金行业中用于连续浇铸使用的耐火材料,主要用于中间罐的开闭,通过控制塞棒头部至中间罐水口的位置来调节进入结晶器的钢水流,进而控制中间包的开浇、关闭以及结晶器的钢流,以保证钢水在结晶器中液面的稳定和连铸工序的稳定。
整体塞棒由棒头和棒身复合而成,棒头根据使用条件分为铝碳质、镁碳质、尖晶石碳质以及锆碳质棒头,而棒身材料一般采用铝碳质。作为帘线钢生产最后环节的冶金容器,中间包用耐材的无铝化是控制帘线中钢硬质夹杂物含量的重要因素。目前,国内整体塞棒的棒身大多以铝碳材质为主,该种材质的耐火材料具有抗热震稳定性强、抗冲刷、抗侵蚀性,能够满足长寿命连续浇铸的使用要求;但该种材质在应用于帘线钢生产时,容易在钢水中引入铝质脆性夹杂,导致生产出的帘线钢钢坯拉丝过程中易断裂,难以满足钢铁企业对生产更高洁净度帘线钢的指标要求。
钢帘线在拉拔与捻股过程中会因氧化铝和氮化钛等脆性夹杂物的存在,而极易出现断裂问题。帘线钢是生产钢帘线的重要材料,整体塞棒是浇铸帘线钢的控流元件,传统整体塞棒在长时间浇钢过程中,棒身的渣侵蚀处会因钢渣侵蚀和低熔物的存在,导致棒身中的氧化铝和钛等脆性杂质混入钢水中。为防止在浇铸帘线钢过程中整体塞棒棒身中的氧化铝和钛混入钢水中,得到洁净度更纯、品质更高的帘线钢,必须将整体塞棒的棒身材料改成超低铝无钛的镁碳材质,从而降低帘线钢中氧化铝和氮化钛等脆性夹杂物的混入。但是和铝碳棒身相比,镁碳棒身具有抗热震稳定性差、强度低等缺点,导致其在使用时容易出现炸裂、断等问题,因此传统技术中镁碳材质很少作为塞棒的棒身材质。
发明内容
本发明提出一种整体塞棒用棒身材料,解决了现有技术中铝碳质棒身容易在钢水中引入铝质脆性杂质、导致帘线钢钢坯易断裂的问题。
本发明的技术方案是这样实现的:
一种整体塞棒用棒身材料,由下述重量份的原料制成:镁砂60~75份,鳞片石墨20~30份,高温烧结剂1~5份,抗氧化剂2~10份,以及结合剂10~15份;所述高温烧结剂为硅微粉或硼玻璃;所述抗氧化剂为金属硅粉、碳化硅粉、碳化硼粉、氮化硅、氮化硅铁、氮化硼中的一种或三种;所述结合剂为酚醛树脂。
作为优选,所述镁砂采用电熔镁砂或烧结镁砂,其中氧化镁的含量大于90%,二氧化硅的含量不大于10%。
作为优选,所述鳞片石墨中的碳含量不小于90%。
本发明所述的整体塞棒棒身为镁碳材料,棒头也是镁碳质,棒头和棒身之间采用过渡料,过渡料即为棒头料和棒身材料按一定比例混合均匀后的材料。
本发明采用电熔镁砂或烧结镁砂以及石墨为主要原料制备整体塞棒的棒身,通过加入适量抗氧化剂,能够降低镁碳材料的热膨胀系数,增加其抗热震稳定性;通过加入高温烧结剂硅微粉或硼玻璃,能够增加镁碳棒身材料的常温强度,增强其抗侵蚀、抗磨蚀和抗剥落能力,使其具备抗渣性能好、热震稳定性高、耐高温的特性,以满足整体塞棒棒身材料的使用要求,满足帘线钢生产的要求。
上述抗氧化剂中的氮化硅、氮化硅铁、氮化硼具有热膨胀率低,高温强度高,抗侵蚀性好等特性。
本发明的有益效果为:
本发明通过采用电熔镁砂或者烧结镁砂取代棕刚玉作为整体塞棒棒身的主要原料,可满足帘线钢等特殊钢种用整体复合塞棒材质超低铝无钛的要求;同时通过加入特定的抗氧化剂和高温烧结剂,改善了镁碳质棒身的抗热震稳定性和强度。
