Titanium calcium aluminate refractory ramming material special for aluminum melting furnace and preparation method of titanium calcium aluminate refractory ramming material
The invention belongs to the technical field of refractory materials, and discloses a special refractory ramming material for a titanium calcium aluminate aluminum melting furnace and a preparation method thereof, the special refractory ramming material is formed by mixing aggregate, a plasticizer, a liquid binder and a strength retention agent, the aggregate comprises titanium calcium aluminate, compact mullite and alumina; the plasticizer comprises one or more of refractory clay, Guangxi white mud and sodium bentonite. The preparation method has the beneficial effects that the titanium calcium aluminate, the compact mullite and the aluminum oxide are used as aggregates in the ramming material, the refractory clay, the Guangxi white mud and the sodium bentonite are used as plasticizers, the titanium calcium aluminate reacts with free silicon dioxide in the plasticizers under the condition of high-temperature sintering, volume expansion occurs, material shrinkage caused by the clay and the plasticizers is made up, and the service life of the ramming material is prolonged. And micro cracks caused by shrinkage are blocked, and the slag resistance is good, so that the titanium calcium aluminate aluminum melting furnace lining is not easy to infiltrate by molten aluminum, and the service life of the refractory material for the aluminum melting furnace is greatly prolonged.
本发明属于耐火材料技术领域，公开了一种钛铝酸钙质的熔铝炉专用耐火捣打料及其制备方法，由集料、增塑剂、液体结合剂和强度保持剂混合而成，所述集料包括钛铝酸钙、致密莫来石、氧化铝；所述增塑剂包括耐火黏土、广西白泥和钠基膨润土中的一种或多种。本发明的有益效果是：捣打料中采用钛铝酸钙、致密莫来石、氧化铝作为集料，耐火黏土、广西白泥和钠基膨润土作为增塑剂，在高温烧结的条件下，钛铝酸钙与增塑剂中的游离二氧化硅反应，发生体积膨胀，弥补了黏土和增塑剂造成的材料收缩，堵住了收缩导致的微裂缝，抗渣性能好，因此钛铝酸钙质的熔铝炉炉衬不易被铝水浸润，大幅提高了熔铝炉用耐火材料的使用寿命。
