Embodiment 1
Multinomial die forging be consecutive production, rhythm be 15 minutes four.For configuration three pilot trench unit quenching tank, often
Interval can carry out primary quenching for 15 minutes, and the cool time of technique setting is 45 minutes.Namely when the first pilot trench enters water quenching
15 minutes afterwards, the second pilot trench started into water quenching, and after the second pilot trench enters water quenching 15 minutes, the 3rd pilot trench starts into water quenching
Fire, when the 3rd pilot trench enters water quenching 15 minutes, the first pilot trench has completed the quenching of 45 minutes it is necessary to quenching of next round is met in discharging
Fire.A unit quenching tank being made up of three pilot trench is exactly the circulate operation so gone round and begun again, and realizes consecutive production
Function.
After first group of workpiece is come out of the stove, infrared ray sensor sends signal, and cooling tower supply-water pump 11 starts.System default
One pilot trench enters the starting stage run, and outside the first pilot trench endoporus cooling valve 6 and the first pilot trench, cooling valve 9 opens 80%, and
Second pilot trench and the 3rd pilot trench enter preparatory stage, the 3rd pilot trench endoporus cooling valve 4, second pilot trench endoporus cooling valve the 5, first son
Outside groove endoporus cooling valve 6 and the 3rd pilot trench, cooling valve 7 all opens 10%, and unit quenching tank is prepared the stage, and now first
Pilot trench has been enter into the circular flow state of big flow.
First group of 4 workpiece simultaneously enters the first pilot trench quenching, and cooling medium consumption reaches the 80% of total flow.After 2 minutes,
Workpiece peak heat release mistake, system call interception the first pilot trench endoporus cools down valve 6 and the open degree of the first pilot trench outside cooling valve 9 is
60%.
When first group of workpiece enters the first pilot trench the 13rd minute, that is, first 2 minutes of second group of workpiece quenching, system is by the

Drive cooling valve 7 greatly to 30%, the 3rd pilot trench endoporus cooling valve 4 and the 3rd pilot trench with cooling valve 9 outside the first pilot trench to maintain
10% open degree.
When first group of workpiece entrance first pilot trench quenches the 28th minute, that is, first 2 minutes of the 3rd group of workpiece quenching, it is
First pilot trench endoporus is cooled down cooling valve 9 open degree outside valve 6 and the first pilot trench and is adjusted to 10% by system automatically, the second pilot trench endoporus
Outside cooling valve 5 and the second pilot trench, cooling valve 8 is opened and is cooled down cooling valve 7 outside valve 4 and the 3rd pilot trench to 30%, the 3rd pilot trench endoporus
Open to enter to 60%, the 3rd pilot trench and treat running status.
When first group of workpiece entrance first pilot trench quenches the 30th minute, outside the 3rd pilot trench endoporus cooling valve 4 and the 3rd pilot trench
Portion's cooling valve 7 is driven cooling valve 8 greatly to 80%, second pilot trench endoporus cooling valve 5 and the second pilot trench further and is adjusted to 10%
Open degree, the 3rd group of workpiece enter the 3rd pilot trench quenching.When 3rd group of workpiece entrance the 3rd pilot trench quenches 2 minutes, the 3rd son
Outside groove endoporus cooling valve 4 and the 3rd pilot trench, cooling valve 7 is automatically regulated to be 60% again, the second pilot trench endoporus cooling valve 5 and second
Outside pilot trench, cooling valve 8 is 30%, and outside the first pilot trench endoporus cooling valve 6 and the first pilot trench, cooling valve 9 keeps 10%.
