Lightweight refractory material with thermal insulation function for aluminum processing and casting
The invention belongs to the technical field of aluminum processing and casting, and relates to a lightweight refractory material with thermal insulation function for aluminum processing and casting. The material can be prepared by casting molding of ceramic slurry, whiskers and chopped ceramic fibers are added into the ceramic slurry, the curing reaction adopts the combined action of an inorganic cementing material and silica sol cross-linked gel, and a product biscuit prepared by the process method is high in strength, short in demolding time and accurate in size, and can meet the molding manufacturing of various complex special-shaped functional devices. Therefore, the method is an effective way for rapidly, simply and low-cost obtaining of various special-shaped functional devices for aluminum processing and casting, the obtained product also has good heat insulation property, strength, erosion resistance and scouring resistance, and a good use effect is achieved in aluminum casting sections of related manufacturers.
本发明属于铝加工熔铸技术领域，涉及一类铝加工熔铸用轻质保温功能耐火材料。该材料可通过陶瓷料浆浇注成型制备，陶瓷料浆中添加有晶须与短切陶瓷纤维，固化反应采用无机胶凝材料与硅溶胶交联凝胶共同作用，该工艺方法制备的制品素坯强度大、脱模时间短、尺寸精准，可满足各种复杂异型功能器件的成型制作。因而，该方法是一种快速、简单、成本低地获得各种铝加工熔铸用异型功能器件的有效途径，所得制品也兼具良好的隔热性、强度、抗侵蚀性以及耐冲刷性，在相关厂家铝熔铸工段已取得了良好的使用效果。
