Research On Control System Of Straightening And On-line Electrical Heating For Titanium And Titanium Alloy Profiles

titanium and titanium alloy profiles has the low elastic modulus and high yield ratio,it has difficulty in straightening titanium and titanium alloy coldly,the straightening of titanium and titanium alloys must be combined with heating,and the temperature window of straightening processing is relatively narrow,it has strict requirement for equal temperature and accuracy of the heating temperature,so.It is of great significance to study the on-line heating control system of titanium and titanium alloy profiles.This paper analyses the equipment and technology for the straightening treatment of titanium and titanium alloy profiles.According to the control requirements for the temperature and straightening process of titanium and titanium alloy profiles,This paper designs a scheme for the control system of electric heating of titanium and titanium alloy profiles.By analyzing the on-line heating control system,this paper establishes a mathematical model of online electric heating,and proposing the control strategy based on fuzzy PID control algorithm to realize the control requirements of temperature consistency and accuracy of two points on titanium and titanium alloy profiles.MCGS and MATLAB data interaction is realized through OPC technology,the industrial personal computer adopts MCGS software to design the interface to setting the parameters such as tensile force,heating temperature,twisting Angle and other parameters,the interface also display heating temperature,heating current,heating voltage and other parameters at real time.Meanwhile,it also can storage parameter alarm and real-time information,making the equipment be used conveniently.The actual operation results of the on-line heating control system shows that the system plays an important role in stabilizing the straightening process and improving the straightening quality.accuracy of titanium and titanium alloy profiles 's heating temperature is controlled in ±8?,The temperature difference of profile is maintained in ±20?,so it is of typical application value to the processing and production of rare metals.
