中文摘要：选用石英粉和铝矾土熟料作为复合耐火骨料，以改性淀粉作为粘结剂，钠基膨润土和粉状纤维素（CMC）作为复合悬浮剂，通过正交试验确定铸钢水基消失模涂料的最佳配比，即钠基膨润土含量1.5％，粉状CMC含量1.5％，改性淀粉含量1.2％。并进行生产验证，结果表明该涂料具有良好的工艺及工作性能，解决了现有涂料在使用过程中存在的问题，能够很好的满足实际生产需要，且成本低廉，具有推广应用价值。
英文摘要：The optimum mixing ration of a water-based coating for steel EPC casting was established through orthogonal experiments, in which silica and alumina clinker flour were used as composite refractory materials, modified starch as binder and sodium bentonite and powdered cellulose (CMC) as composite suspension agent, that was sodium bentonite powder containing 1.5%, CMC 1.5%, modified starch containing 1.2%.It was proved by production test that the properties of developed coating were good, and could solve the existing problems in the process and meet production requirements. Therefore it could be videly used in EPC casting processes.
