| 摘 要： | 以煅烧二级矾土熟料为集料，合成莫来石、白刚玉粉、ＳｉＯ２微粉、Ａｌ２Ｏ３微粉为粉料，两种纯铝酸钙水泥为结合剂（加入量５％－７％），复合聚磷酸盐作分散剂，研制出高强度莫来石基质浇注料。经１５５０℃，３ｈ热处理后，浇注料的体积密度为２．４２８／ｃｍ３，耐压强度达８７．７ＭＰａ，烧后线变化率＋０．１５％，抗铁法侵蚀性、抗剥落性良好。用于武钢４＃取向硅钢加热炉的步进梁、固定梁和立柱上，寿命比原ＣＭ１６Ｃ浇注料高２．５倍。

| Abstract: | Using fired boukite as aggregnte,synthesized mullite, white corundum,microsilicas and microalumina as powder, two purecalcium aluminate cements as binder,and complex polyphosphates as deflocculant the Castsble with mullite matrixes was develop. The bulk density of the castable is 2. 42g/cm3,crushing strength is 87. 7MPa aam linear avenge aftet firing at 1550C is 0. 15K. The CaStable has gial resistance to iron slag and gial resistance to thermal shock. When uest in walking beam fixedbeam and uptight column of N04 reheating furnace for Producing grain-oriented electrical steel in Wuhan iron and Steel Co..Its scrviot life is more thsn 2. 5 times that of the CMI 6C castable. |
