Ultrafast cooling control method for H-shaped steel

An H-beam ultra fast cooling control method for automatic control technology belonging to rolling, the system includes a universal mill used in the control unit and the control unit ultra fast cooling; the control unit comprises a universal rolling mill process control computer, PLC and the UF universal mill, UFC The control unit comprises a process control computer, PLC, hot metal detector, thermometer, and a pneumatic valve group. According to the present invention is H-beam steel, and final cooling target specifications process requirements, determining UFC control strategy, i.e. valve open priority, strict control of the finishing speed steel and cast steel bite, uniform beam of H by ultra fast cooling area, and a mathematical model of ultra fast cooling process, flange and web to achieve precise control of temperature, H-beam ultrafast cold temperature control accuracy greatly improved, self-learning through the model, the ultra-fast cooling process more reasonable , reliable, high speed and stable control of the H-beam cooling, can ensure the horizontal and vertical cooling uniformity.
