| description | The invention discloses a method for preparing a low-aluminum mullite refractory brick from waste electroceramics, and relates to the technical field of comprehensive utilization of solid wastes and refractory materials. The low-aluminum mullite refractory brick is prepared by taking waste electrical porcelain as a raw material, a water glass solution as a binding agent and industrial solid waste aluminum ash and clay as wrapping materials through the processes of weighing and batching, uniformly mixing the materials, wrapping the wrapping materials, drying, mechanically pressing, performing high-temperature heat treatment and the like. According to the invention, based on the characteristics of block shape, granulation, compactness, hardness and high temperature resistance of the waste electroceramics and the current situation of low added value utilization of solid wastes, the wrapping material is introduced to shield low-melting-point components with deteriorated high temperature performance in the colored |
