Production process of high-strength refractory material
The invention belongs to the technical field of refractory material production processes, and particularly relates to a high-strength refractory material production process which comprises the following steps: S1, burdening; S2, preparing a pre-forged material: uniformly mixing magnesite powder, fly ash and dolomite powder, calcining at 1650-1850 DEG C, and crushing the calcined material to obtain the pre-forged material; S3, mixing and sieving; S4, preparing a brick blank; and S5, sintering: sintering the brick blank dried in the S4, and naturally cooling to the room temperature. According to the invention, the defects of moisture absorption, efflorescence, frosting, deformation, poor water resistance and the like of magnesite products are effectively overcome, the effect of enhancing the toughness of refractory material products can be achieved, the volume density of the material is improved, and the heat resistance, strength, flame retardant property and thermal stability of the material are greatly improved; and the prepared refractory material product has the characteristics of high breaking strength, high torsional strength, high compressive strength and high tensile strength, and is excellent in mechanical property, and the comprehensive performance is remarkably improved.
本发明属于耐火材料生产工艺技术领域，尤其为一种高强度耐火材料生产工艺，包括以下步骤：步骤S1、配料；步骤S2、制预锻料：将菱镁粉、粉煤灰和白云石粉混合均匀，并于1650℃～1850℃下煅烧，将煅烧后的物料粉碎，得预锻料；步骤S3、混料、过筛；步骤S4、制砖胚；步骤S5、烧结：将经S4步骤干燥后的砖胚进行烧结，自然冷却至室温。本发明有效克服了菱镁制品存在吸潮返卤、返霜、变形及耐水性差等缺陷，能够起到增强耐火材料制品韧性的作用，提高材料的体积密度，大大提高了材料的耐热性、强度、耐火度及热稳定性，制得的耐火材料制品具有高抗折强度、高抗扭强度、高耐压强度和高抗拉强度的特性，力学性能优异，综合性能提升显著。
