Embodiment Construction
[0014] Below, the present invention will be described in further detail in combination with examples.
[0015] Taking a single stand of a 5-meter rolling mill in a wide and heavy plate factory as an example, in 2018, the existing general method was used to control rolling. The average number of rolling blocks per hour was 12, and the rolling time of each steel plate was 5 minutes. The rolling efficiency was low. A large amount of energy waste occurs in the rolling gap.
[0016] Adopt a kind of method of improving the rolling rhythm of 5 meters rolling mill of the present invention to optimize the rolling process, comprising:
[0017] 1. Optimize the control logic of roll gap action and roll shifting action, and shorten the rolling time of each steel plate by 4.0 seconds.
[0018] Specifically, when the first pass of rolling is a non-steel transfer pass, and the roll gap is lifted from the steel throwing value of the previous piece to more than 200mm, the roll gap and roll shi...
