技术领域
本发明涉及耐火材料技术领域,特别涉及一种锆质自流浇注料。
背景技术
耐火度不低于1580℃的一类无机非金属材料。耐火度是指耐火材料锥形体试样在没有荷重情况下,抵抗高温作用而不软化熔倒的摄氏温度。但仅以耐火度来定义已不能全面描述耐火材料了,1580℃并不是绝对的。现定义为凡物理化学性质允许其在高温环境下使用的材料称为耐火材料。耐火材料广泛用于冶金、化工、石油、机械制造、硅酸盐、动力等工业领域,在冶金工业中用量最大,占总产量的50%~60%;使用耐火材料过程中,原有的耐火材料的抗龟裂性能较差。
发明内容
本发明的主要目的在于提供一种锆质自流浇注料,可以有效解决背景技术中的问题。

一种锆质自流浇注料,包括:骨料、粉料、掺和料;
骨料为占骨料与粉料质量之和的70~80%高铝矾土熟料、亚白刚玉、锆英石、斜锆石,
粉料为占骨料与粉料质量之和1%~6%硅微粉、占骨料与粉料质量之和1~10%亚白刚玉粉、占骨料与粉料质量之和1~12%氧化铝粉、占骨料与粉料质量之和2%~3%氧化锆粉、占骨料与粉料质量之和1~10%白泥、占骨料与粉料质量之和0%~25%高铝矾土熟料粉、占骨料与粉料质量之和0~3%高铝水泥、占骨料与粉料质量之和0~6%纯铝酸钙水泥,
掺和料为占骨料与粉料质量之和的0.1~0.3%六偏磷酸钠、占骨料与粉料质量之和的4%~7%水。
优选的,所述骨料分为粗骨料和细骨料,且粗骨料占骨料中40%-50%,所述细骨料占骨料中30%-40%,所述细骨料为锆英石、斜锆石。
优选的,氧化锆粉为纯氧化锆粉。
一种锆质自流浇注料的制备工艺,其特征在于:包括以下步骤:
步骤一:物料配比,按照各物料的比重进行配比,各物料分开存放;
步骤二:加入搅拌机,各物料加入搅拌机搅拌仓内,搅拌至振动成形所要求的流动度;
步骤三:准备模具和养护,置于模具中浇筑成形,带模养护和脱模养护,养护时间为24小时以上;
步骤四:入炉烘烧,投入烘烧炉中进行烘烧,温度呈线性上升,最高温度为1200度;
步骤五:冷却和检验,烘烧炉中冷却,出炉检验;
