Under the premise of, during transition volume operates in annealing furnace i-th process section, strip design temperature raises 80 DEG C.Then in a upper coil of strip
Band rear, also with 2min for time interval 2 times rising strip design temperatures.Monitor that the default band rear of a steel reaches to move back
The belt steel temperature monitoring point of stove i-th process section starts:Transition volume operates in annealing furnace the during annealing furnace i-th process section
The strip design temperature of i process section repeatedly raises strip design temperature with 2min for time interval, to reach next coil of strip i-th
Process section annealing design temperature.
It should be noted that in the present embodiment, three prefixed time interval >=2min, strip design temperature is risen
High single regulated quantity≤5 DEG C, thus after ensure that each regulation belt steel temperature setting value, strip actual temperature can be followed and be reached
To this belt steel temperature setting value after raising, and then ensure that strip actual temperature reaches belt steel temperature setting value and just rises again
High strip desired temperature.Further, the 3rd prefixed time interval is 2min in the present embodiment, and single regulated quantity is 5 DEG C,
Enable on the premise of after ensureing every time to adjust belt steel temperature setting value, strip actual temperature is followed, it is right also to reduce as far as possible
The annealing effect length of a upper coil of strip, and do not interfere with high warm rolling (next coil of strip of the present embodiment middle finger) completely.
