First: strengthen the processing of raw materials, reduce molding moisture, and improve the strength of the green body.
First: strengthen the processing of raw materials, reduce molding moisture, and improve the strength of the green body.
Two: increase the temperature of the green body. The relative humidity of the exhaust gas is controlled at about 95%, which should not be too high, so as to avoid condensation in the early stage of the green body entering the drying road, hindering the discharge of moisture inside the brick, and then suddenly encountering high temperature and low humidity gas, so that the green body is rapidly dehydrated and cracked.
Three: control the residual moisture of the green body after drying at about 6%, and enter the kiln in time to avoid cracking due to the low residual moisture of the green body and the absorption of moisture in the outside world.
Four: When the fan is temporarily stopped due to power failure or maintenance, open the end doors and inspection ports to allow moisture to escape, so as to prevent the green body that has been removed from some moisture from absorbing moisture and cracking again in the drying channel.
