How to solve the shell, the crack problem of refractory material in the process of forming.

Answer:

Pressure mode and number of pressure control "spallation". 2, multiple pressure, pressure degree and discharge way: 1, reduce friction, choose appropriate, than big pressure disposable pressure produced by the plastic deformation, allocate reasonable grading, internal and external friction, reduce billet particles and high die wall bright. 4.--- solve the light one firstly. --moisture content being too high easily cause spallation - the compressibility of water is small and have certain elasticity, appropriately to extend the pressuring time is beneficial. The material can produce large plastic deformation under the effect of continuous load. The right amount of lubricant. - body under the condition of less pressure but long effect time molding. Mould structure is reasonable and improve billet natural stacking density. 5.3, measures to improve the unburned brick molding quality. Many times continuously pressure relief is better than one-off sudden unloading, and controlling the appropriate moisture content;- - is beneficial to air overflow.
