Then in control part second solenoid valve 23-2, Grouting Pipe 24-2 in opening, start to carry out slip casting work.Part is all in the middle
The temperature that thermocouple 10 measures all is reduced to set critical temperature value hereinafter, being shut off the second solenoid valve 23- of middle part
2, complete slip casting process.Four from shifting heat pipe 6, all centering portion carries out continued down before and after slip casting, the middle part before and after slip casting
Four heat extraction galvanic couples 10 are divided persistently to carry out temperature monitoring.
Instantly when the temperature that any one thermocouple measures in four heat extraction galvanic couple 10 of part is higher than the temperature threshold value of setting,
The third solenoid valve 23-3 for then controlling lower part opens lower Grouting Pipe 24-3, starts to carry out slip casting work.Instantly part is all
The temperature that thermocouple 10 measures all is reduced to set critical temperature value hereinafter, being shut off the third solenoid valve 23- of lower part
3, complete slip casting process.Lower part, from heat pipe 6 is moved, can only carry out cooling work, lower part by grouting system without four
Four heat extraction galvanic couples 10 are divided still persistently to carry out temperature monitoring.
Described in summary, when the temperature that thermocouple 10 measures is higher than set critical temperature value, upper, middle, and lower part
Solenoid valve controlled respectively by the thermocouple of upper, middle, and lower part, the temperature threshold value of which part is exceeded to open for which part
Solenoid valve starts to carry out slip casting work.When the temperature that thermocouple measures is reduced to set critical temperature value hereinafter, being shut off
Solenoid valve completes the slip casting cooling course of work.Before and after slip casting, heat pipe can only be carried out to upper and middle two parts from heat pipe 6 is moved
Cooling processing, does not carry out hot pipe cooling processing to lower part.Before and after slip casting, the thermocouple 10 in fin 8 is all to dump surface
Temperature carries out lasting daily monitoring.
