Embodiment Construction
[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0032] The embodiment of the present invention provides a continuous hot-dip galvanizing inlet loop tension control method, which is applied to a continuous hot-dip galvanizing control system. The continuous hot-dip galvanizing inlet loop tension control method controls the continuous hot-dip galvanizing inlet section. Specifically, such as figur...

The invention discloses a continuous hot galvanizing entry looper tension controlling method and a controlling system. When length of rest band steel on an uncoiler is monitored to be smaller than preset band steel length, a tension set value given by an entry looper system is judged; when the tension set value given by the entry looper system is judged to be smaller than a preset tension lower limiting value, the looper tension is adjusted based on the tension set value given by the entry looper system; when the tension set value given by the entry looper system is judged to be larger than a preset tension upper limiting value, the looper tension is adjusted based on the tension set value given by the entry looper system; and when the tension set value given by the entry looper system is judged to be larger than or equal to the preset tension lower limiting value and to be smaller than or equal to the preset tension upper limiting value, the tension set value for adjusting current lopper tension is confirmed based on a preset linear relation, and the looper tension is adjusted. According to the continuous hot galvanizing entry looper tension controlling method and the controlling system, a situation that a first tensioning roller slips when the tail of the uncoiler swings is effectively avoided, and a problem that the band steel slides to the entry looper is solved.
Description
technical field [0001] The invention relates to the field of strip steel processing, in particular to a continuous hot-dip galvanizing inlet looper tension control and control system. Background technique [0002] The continuous hot-dip galvanizing production line is a complete set of equipment in which the strip steel is heated and galvanized to continuously produce galvanized steel sheets during the traveling process. [0003] In the entrance section of the continuous hot-dip galvanizing production line, when the tail of the uncoiler flicks, the tension in the entrance section disappears when there is no strip steel on the uncoiler or the entrance scissors cut the strip tail. At this time, the tension of the entrance loop is completely tensioned by No. 1 Roll balance, the tension setting value of the existing entry looper is always provided by the system, and the tension setting value of the entry looper provided by the system is calculated once for each coil, therefore, f...
