Embodiment Construction
[0017] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0018] This embodiment provides a control method, by detecting the steel passing current of the reducing and sizing, rough rolling, intermediate rolling and pre-finishing mill units, judging the abnormal situation in production, and automatically realizing the variable speed. Using ABB PLC and frequency converter, the performance is stable and reliable, and it can realize automatic energy saving.
[0019] Such as figure 1 As shown, first, set the speed control switch of the roller table and the fan to the "automatic" state on the console operation interface. When the Stelmo air-cooled line is wo...

The invention relates to a method for regulating the speed of a roller table and a fan of a Stelmore air-cooled line, comprising the following steps: setting the speed regulation switch of the roller table and the fan to "automatic" on the console operation interface; detecting and reducing the speed during the production process Diameter and rough rolling, intermediate rolling, and pre-finishing steel passing current, if there is no steel feeding within 30 seconds, it will be judged that there is an abnormality, and the roller table and fan will be automatically reduced in speed; the speed of the fast roller table will be reduced to 80%, and the slow speed will be reduced to 80%. The roller table is reduced to 50%, and the fan is reduced to 30%. It is detected that there is a steel current on the first frame of the rough rolling unit, and the fan and roller table start to increase in speed; Fan and roller speeds are ramped up to original normal production speeds. Realize automatic detection of steel passing status, automatic speed regulation of roller table and fan, and realize energy saving purpose.
Description
technical field [0001] The invention relates to the technical field of energy-saving of the Stelmore roller table for rolling steel, in particular to the control of the roller table and the fan speed of the Stelmore air-cooled line. Background technique [0002] As energy conservation and emission reduction are deeply rooted in the hearts of the people, cost reduction and expenditure reduction play a vital role in the sustainable development of enterprises in order to tap the potential. As a steel rolling workshop, in the continuous production process, if the production stops for a long time, the fan will be stopped directly, and the roller table will stop manually after running at a slow speed for 20 minutes. If there is a short-term production failure (generally 2-3 minutes), the energy-saving space on the main rolling line is relatively small. The roller table and fan of the Stelmore cooling system have a certain energy-saving space, but the frequent start and stop of th...
