| 摘 要： | 以电熔大结晶镁砂、天然鳞片石墨、纳米炭黑、酚醛树脂、铝粉等为主要原料制备w(C)=3%的低碳MgO-C材料,以其抗热震性为考核指标,选取颗粒级配、复合抗氧化剂、石墨粒度和复合结合剂4个因素,进行了四因素三水平正交试验。结果表明:在本试验范围内,颗粒级配是影响低碳MgO-C材料抗热震性的主要因素,复合抗氧化剂次之,石墨粒度和复合结合剂的影响基本相当;通过极差分析确定,镁砂颗粒级配(3～1、1～0.088和≤0.088mm的镁砂的质量比)采用50:23:27,复合抗氧化剂采用Al2.5+Mg-Al0.5+B4C0.5,石墨粒度采用10μm的,复合结合剂采用炭黑N220+沥青+酚醛树脂,可制备出抗热震性最佳的低碳MgO-C材料。 |

| Abstract: | The low carbon MgO-C(w(C)=3%)materials were prepared using fused magnesia,natural flaky graphite,nano carbon black,phenolic resin,and aluminum powder,etc.as starting materials.Influences of four parameters(grain size distribution,composite antioxidants,graphite grain size and composite binder)on thermal shock resistance of the low carbon MgO-C materials were studied by four factors and three levels orthogonal test.The results show that:grain size distribution is the main influencing factor,and then the comp... |
