Mullite refractory castable for ultrahigh-temperature smelting
The invention belongs to the technical field of refractory materials, and particularly relates to a mullite refractory castable for ultrahigh-temperature smelting. The mullite refractory castable forultrahigh-temperature smelting is prepared from the following raw materials: mullite particles, fused quartz particles and andalusite-family particles, which serve as aggregates; fine mullite powder,fine monoclinic zirconium oxide powder, alpha-Al2O3 micro-powder and hydrated alumina, which serve as a matrix; a water reducing agent; and water. According to the invention, high-purity mullite is used as a main raw material a certain grain composition is adopted, and a proper binding agent and a proper dispersing agent are selected, so a refractory material with high fire resistance, good thermal shock resistance and molten liquid/slag corrosion resistance can be obtained; and the material can replace an existing carbon product which is easy to oxidize at high temperature, and meets smeltingworking conditions at an ultrahigh temperature of 1700 DEG C or above.
本发明属于耐火材料技术领域，具体涉及一种超高温冶炼用莫来石质耐火浇注料。涉及的一种超高温冶炼用莫来石质耐火浇注料的的原料以莫来石颗粒熔融石英颗粒以及红柱石族颗粒为骨料，以莫来石细粉、单斜氧化锆细粉、а‑AlO微粉和水合氧化铝基质：外加有减水剂和水。本发明以高纯莫来石为主原料，采用一定的颗粒级配，同时选择合适的结合剂和分散剂，可获得具备高耐火性、良好抗热震性能、抗熔液/熔渣侵蚀性能的耐火材料，取代现有高温下易氧化的碳素制品，满足1700℃以上的超高温冶炼工况条件。
