Embodiment 1
[0036] combine figure 1 , a kind of method for building a horizontal continuous annealing furnace of a cold-rolled sheet processing line of the present embodiment. After the furnace area is overhauled, the production stage is resumed, and the strip steel enters the furnace heating area 8 through the transmission of the front tension roll 1 (that is, the 2# tension roll) , the heated strip passes through the heat-stretching roller 4, enters the zinc pot 3, and then runs to the water quenching tank 7 through the pinch roller, and finally is transported to the next process by the rear tension roller 6 (that is, 3# tension roller) . During the entire conveying process of the strip steel, the TM2 tensiometer 2 monitors the actual tension value of the strip steel at the furnace entrance in real time and gives feedback, and the TM3 tensiometer 5 monitors the actual tension value of the strip steel in the water quenching section in real time and gives feedback. Compare with the set t...
