Refractory casting material
The invention belongs to the technical field of gypsum materials, and particularly discloses a refractory casting material, which is prepared from the following components in parts by weight: 290 to 330 parts of coarse aggregate, 280 to 330 parts of fine aggregate, 180 to 230 parts of alumina clinker, 160 to 200 parts of refractory cement, 20 to 25 parts of silica fume, 5 to 10 parts of aluminum oxide micro powder, 2 to 3 parts of sodium tripolyphosphate water reducing agent, 1 to 1.5 parts of polycarboxylic acid water reducing agent, 0.5 to 1.0 part of cellulose ether and 0.15 to 0.25 part of defoaming agent. And 160 to 200 parts of water. The three aggregates are compounded, so that the fire resistance is improved, and high-temperature cracking is avoided; the polycarboxylic acid water reducing agent and the sodium tripolyphosphate water reducing agent are compounded, so that the water consumption for stirring is reduced, and good construction performance is ensured; the alumina micro powder and the silica fume are added, so that the compactness is improved, and the compressive strength and the breaking strength of the material are improved; cellulose ether is added to enhance the water-retaining property of the material.
本发明属于石膏材料技术领域，具体公开了一种耐火浇注材料，包括如下重量份的组分：粗骨料290‑330份，细骨料280‑330份，矾土熟料180‑230份，耐火水泥160‑200份，硅灰20‑25份，氧化铝微粉5‑10份，三聚磷酸钠减水剂2‑3份，聚羧酸减水剂1‑1.5份，纤维素醚0.5‑1.0份，消泡剂0.15‑0.25份，水160‑200份。本发明采用三种骨料复配，提高耐火性能，避免高温开裂；采用聚羧酸减水剂和三聚磷酸钠减水剂复配，降低搅拌用水量，并保证良好的施工性能；添加氧化铝微粉和硅灰，提高密实性，增加材料的抗压、抗折强度；添加纤维素醚增强材料的保水性。
