<meta name="description" content="低水泥系列耐火浇注料是在黏士结合耐火浇注料的基础上开发的，也是在20世纪80年代得到蓬勃发展的新一代耐火浇注料。其中主要品种有低水泥、超低水泥和无水泥等耐火浇注料，它集多数耐火浇注料的优点于一身，具有高密度、低气孔高强度、低磨损、耐热震和抗侵蚀等特性，因此应用较广泛，使用效果较好和社会经济效益显著。 低水泥系列耐火浇注料根据性能特点，可称为高科技耐火浇注料、高性能耐火浇注料、致密高强耐火烧注料、低气孔耐火浇注料和低水分耐火浇注料等；根据其用途,则分为高炉出铁沟耐火浇注料和炼钢钢包耐火浇注料等；">

<p class="summary">镁质或高铝尖晶石质耐火浇注料是为钢包内村而开发的。耐火骨料为纯镁砂或特级矾土熟料，耐火粉料为镁铝尖晶石粉。结合剂为复合结合制,同时掺加外加剂。该类耐火浇注料具有较好的抗渣性、抗剥落性和抗热震性，与镁铝尖晶石耐火浇注料相比，性能稍有逊色，成本显著降低,适合国情，易于推广;与普通抗热震耐火浇注料相比,由于尖晶石的加入，而不是在使用过程中逐渐形成的,因此性能明显提...</p>
