Fracture-resistant refractory material and preparation process thereof
The present invention relates to the technical field of refractory materials, and discloses an anti-fracture refractory material and a preparation process thereof, the anti-fracture refractory material comprises the following raw materials: 20-40 parts of magnesite, 15-20 parts of seawater magnesia, 12-15 parts of dolomite, 30-50 parts of periclase, 3-7 parts of a reinforcing phase comprising silicate, carbide and nitride, 2-5 parts of an adhesive comprising Portland cement and sulfate in an inorganic binder, the production method comprises the following steps: raw material screening, raw material mixing, high-temperature smelting, molding and pouring, heat treatment, cooling and shaping, surface polishing and quality detection, and in the molding and pouring process, vacuum pouring, bubble elimination and other measures are adopted, so that the production process is simple, the production cost is low, and the production efficiency is high. The gas in the refractory material can be fully discharged, and the compactness and the strength of the material are further improved, so that the reliability of the material is improved, the service life of the material is prolonged, and the prepared refractory material is not easy to break under the condition of impact.
本发明涉及耐火材料技术领域，公开了一种抗断裂耐火材料及其制备工艺，包括以下组分的原料：菱镁矿20—40份、海水镁砂15—20份、白云石12—15份、方镁石30—50份、增强相3—7份包括硅酸盐、碳化物、氮化物，粘黏剂2—5份包括无机粘结剂中的硅酸盐水泥、硫酸盐，添加剂5—7份包括三氧化二锑、五氧化二钒、二氧化硅，其生产流程包括原料筛选、原料混合、高温熔炼、成型浇注、热处理、冷却塑形、表面打磨、质量检测，本发明中，通过在成型浇注过程中采用真空浇注和气泡消除等措施，确保了耐火材料内部的气体能够充分排出，进一步提高了材料的致密度和强度，从而提高了材料的可靠性和使用寿命，也使得制成的耐火材料不易在受冲击的情况下产生断裂现象。
