Refractory material for 3D printing and printing method thereof
The invention discloses a refractory material for 3D printing and a printing method thereof. According to the material, the proportion of a traditional refractory casting part is improved, the material is composed of alumina aggregate, aluminate cement, silica fume, activated aluminum oxide micro-powder, additives, fibers and water in percentage by weight; and the additives comprise a solid waterreducing agent, a thickening agent and a thixotropic lubricant, and the additives improve the viscosity, fluidity and stackable property of the material and enhance the printability of the refractorymaterial. A 3D printing technology is used for producing a refractory component in the invention; convenience and rapidness are achieved, an automation degree is high, one-time integral forming of thecomponent is achieved, and large-scale continuous production is facilitated; the printed refractory component is good in compactness, the normal-temperature compression strength of the refractory component is remarkably improved, and production and manufacturing of refractory components which are complex and irregular in structure and difficult to manufacture through molds are achieved; and the whole production process is environmentally friendly, and sustainable development is facilitated.
本发明公开了一种用于3D打印的耐火材料及其打印方法。该材料改进了传统耐火浇注件配比，按重量百分比由矾土骨料、铝酸盐水泥、硅灰、活性氧化铝微粉、添加剂、纤维和水组成，添加剂包括固体减水剂、增稠剂和触变润滑剂，添加剂改善了材料的黏度、流动性和可堆积性，增强了耐火材料的可打印性能。本发明使用3D打印工艺进行耐火构件生产，方便快捷、自动化程度高，构件一次性整体成型，有利于大规模连续生产，打印出的耐火构件不仅致密性好、常温耐压强度显著提高，而且实现了结构复杂不规则、模具难以制造的耐火构件的生产制造，整个生产过程绿色友好，利于可持续发展。
