Preparation process of machined high-strength refractory material
The invention discloses a machining high-strength refractory material preparation process, and belongs to the technical field of refractory materials, and the machining high-strength refractory material preparation process comprises the following steps: weighing raw materials and auxiliary materials according to the mass percentage, crushing, mixing, grinding and presintering the raw materials and auxiliary materials to obtain material powder, ball-milling and mixing the material powder in absolute ethyl alcohol of which the weight is several times of that of the material powder for a plurality of hours, the preparation method comprises the following steps: carrying out ball milling and mixing, drying material powder, carrying out dry pressing molding on the material powder under strong pressure, uniformly spraying a sodium carbonate aqueous solution in the molding process to finally prepare a refractory material green body, sintering the molded refractory material green body at high temperature for several hours, and naturally cooling to room temperature after sintering to prepare the refractory material. The problem that a large number of cracks are generated in a rapid cooling and rapid heating use environment can be solved, and the service life of a product is prolonged.
本发明公开了一种机加工高强度耐火材料制备工艺，属于耐火材料技术领域，包括按质量百分比称取各原辅料，并将其粉碎、混合研磨和预烧，得到材料粉体，将材料粉体在数倍材料粉体重量的无水乙醇中球磨混合多个小时，球磨混合后将材料粉体烘干，将材料粉体在强压下干压成型，成型过程中均匀喷洒碳酸钠水溶液，最终制得耐火材料生坯，将成型后的耐火材料生坯在高温下烧结数个小时，烧结完成后自然冷却至室温，制得耐火材料，本发明能解决在急冷急热的使用环境下产生大量裂纹问题，提高产品使用寿命。
