Packaging steel strip finishing the automation process

Packaging steel strip finishing the automation process exported from roughing to finishing mill group entry table is called delay roller, roller press roller number, also known as E. Have scrap in E direction table on the left side of the pusher, on the right side of a stationary platform, used to handle strip rolling pass. Roller speed controlled by computer, both to shorten the strip in the middle of the running time, and to avoid hitting the two pieces before and after. When the strip out of the last one roughing mill the private, the speed of the roller table and gen frame synchronization. When the strip tail left the R4 frame, computer collision condition check, if not collision, control table 2 is high speed, or speed control table 2 until not collide into a high speed. When this piece of the strip to crop flying shear in front of the hot metal detector HMD4, if the strip is still in its first first finishing mill F1ON, namely the first rolling, strip is still in F1 computer to judge whether collided with first strip, if F1OFF which has no rolled piece, the speed of mill roll gap, whether to set data to check, if there is a collision may, or pass the examination, emit command, make 2 roller inversion delay proceed forward again after 10 s, this back and forth, Each time you connect HMD54 repeat check again) Swing, until qualified, computer remove instruction. When the strip forward to hot metal detector 55, speed measuring roll down, measure the actual speed of the strip, at this time so that the strip forward to 61 hot metal detector, the speed of the strip completely down to be consistent with the speed of flying shear head. On the strip head reached 61 hot metal detector, start flying shears automatically to the strip of irregular or low head cut off. Then the speed of the strip should be further reduced to the first frame and finishing mill group of F1 bite rate, consider compensation under pressure. Cut the tail of the strip speed by descaling box before finishing the second to pinch roll on the roll to test, and then based on this speed to determine the speed at the end of the flying shear, cut tail still use hot metal detector, 61 to start flying shears. In order to avoid the cut off the head and tail on the strip, when crop flying shear speed to be slightly higher than the speed of the strip, cut the tail when the speed of flying shear should be slightly lower than the speed of the strip.
