Abstract
本发明公开了一种铸造熔炼添加剂，它是由原料氧化钠10～15份；氧化铝3.5～8.5份；氧化钾3.5～8.5份；碳酸钠6～11份；二氧化硅3～9份；氧化钙11～18份；氧化铁1.5～8.5份；二氧化钛0.5～2份；聚烯烃热塑弹性体3.1～5.5份；氧化镝1.2～3.3份和五水硼砂5～10份配制而成。本发明的优点在于该添加剂成本低，无毒、无有害成分，不污染环境；熔炼时由于可提高钢水的流动性，减少了成品铸件的气孔和渣孔，提高了铸件的抗压、抗拉强度，使铸件成品率从90％提高至98％；熔炼时，可避免投料出现“架桥”现象；熔炼时炉壁不会粘渣，可以延长炉体寿命20％，缩短熔炼时间1/3，大大节约了耗电量，提高了企业效益。
Description
技术领域
本发明涉及冶炼铸造用辅助材料，尤其是涉及一种可以快速提高熔炼速度的铸造熔炼添加剂。
背景技术
在冶金冶炼铸造行业，熔炼用的各种型号的电炉(如高频、中频或电弧炉等)的熔炼速度对铸造成本的影响非常大，且随着熔炼时间的延长，不仅能源损失大，且污染严重。
发明内容
本发明的目的在于提供一种可以提高熔炼速度、节约能源、减少排放垃圾的铸造熔炼添加剂。
为实现上述目的，本发明可采取下述技术方案：
本发明所述的铸造熔炼添加剂，它是由原料氧化钠(Na2O)、氧化铝(Al2O3)、氧化钾(K2O)、碳酸钠(Na2CO3)、二氧化硅(SiO2)、氧化钙(CaO)、氧化铁(Fe2O3)、二氧化钛(TiO2)、聚烯烃热塑弹性体(TeO)、氧化镝(Dy2O3)和五水硼砂(Na2B4O7·5H2O)按照下述重量份配比配制而成：
氧化钠10～15份；氧化铝3.5～8.5份；氧化钾3.5～8.5份；碳酸钠6～11份；二氧化硅3～9份；氧化钙11～18份；氧化铁1.5～8.5份；二氧化钛0.5～2份；聚烯烃热塑弹性体3.1～5.5份；氧化镝1.2～3.3份和五水硼砂5～10份。
将上述原料用破碎机粉碎至粒度0.05微米～1.6毫米，经振筛、混合均匀后按规格装袋封装即可。
使用时，按照装炉料∶添加剂＝1000∶0.5的比例称取本添加剂，开炉前加料时，先在炉体内加入25％的废钢或铁块后再将本添加料投入，然后将其余的废钢或铁块装入炉膛内进入正常操作熔炼，整个铸造时间可以从90分钟缩短至60分钟。
本发明的优点在于该铸造添加剂成本低，无毒、无有害成分，不污染环境；由于本添加剂可以提高钢水的流动性，减少了成品铸件的气孔和渣孔，提高了铸件的抗压、抗拉强度，使铸件成品率从90％提高至98％；熔炼时，可避免投料出现“架桥”现象；熔炼时炉壁不会粘渣，可以延长炉体寿命20％。按一个3吨中频炉计，正常每小时耗电2000度，每分钟33度，如不用本发明的添加剂，熔炼铸件需要90分钟，加入本添加剂后，可将熔炼时间缩短至60分钟，大大节约了耗电量，提高了企业效益，增加产能；减少了操作工人的劳动强度。
采用标准Y形试片对该添加剂进行实验，其结果如下：
1、机械性能比较(试片厚度30mm)
2、化学成分分析
(1)加添加剂
(2)未加添加剂
3、熔融时间
结论：
(1)机械性能比较后可看出，产品抗拉强度和屈服强度均有所提高，硬度略有降低，但不影响产品机械性能；
(2)产品化学成分分析，各元素数值变化甚微；
(3)熔融时间：无论冷炉或正常生产的热炉，原料熔融时间均缩短约1/3。
