In this paper,the basic structure and control strategy of on-line intelligent quenching system for aluminum profile extrusion production line are described,and the main research and development direction of on-line self-adaptive control for quenching are also discussed,the TCP IP network topology which is composed of industrial control system computer HMI and Programmable Controller PLC is given.In order to meet the requirements of quick response,high stability and high accuracy of the on-line quenching cooling temperature control system,a set of on-line self-adaptive quenching cooling water temperature controller is developed.Thus,the extrusion on-line cooling based on the cooling process model can be automatically adapted to match the temperature.And the temperature adaptation value of the cooling water can be adjusted by the real-time dynamic closed-loop method.The accuracy and stability of the on-line cooling system for the profiles on the extrusion production line are improved,and then the properties of the profiles after quenching are improved on the line.
