  Dry vibration mix is an unshaped refractory material that is vibrated and molded without adding water or liquid binder. Under the action of vibration, the material can form a dense and uniform whole, which can be strengthened by thermosetting bonding agent or ceramic sintering agent when heated. Dry vibration mix is composed of aggregate and powder、binding agent and additive. Dry vibration mix ' s character is : this kind of material is easy to flow under the action of vibration force, and the powder can fill the tiny pores between particle accumulation even under the action of very small vibration force, and obtain a dense body with higher filling density. What's more, it is heated to form a working layer with certain strength. However, there is still a part of unsintered surface showing the original dense accumulation structure. This structure helps to reduce the stress caused by expansion or contraction; Prevent the spread and extension of cracks; Prevent ...
