Design Of Mould Hydraulic Vibration Control System Of Shouqin No.2Slab Continuous Casting Machine

Along with the rapid development of economy, the domestic steel market competition becomes increasingly fierce, efficient continuous casting technology will become the big steel enterprise studies focusing on the subject. The core of the efficiency casting technology is how to improve continuous caster throwing speed, and moulding for continuous caster throwing speed play an important role, if the mould oscillation system can not work normally, which will result in the process of continuous casting of steel and other major accident happened leakage. So the mould vibration control system has the important research application value and practical meaning.2005,Qinhuangdao of Hebei Metals Shouqin from the United States SMS (SMS DEMAG) the company introduced a2#Slab Caster,the continuous casting machine can produce the maximum width of2400mm,320mm thickness of the slab. The same time also introduced hydraulic mold oscillation system from the United States SMS (SMS DEMAG). As the system debug time is short, there is no test for different kinds of vibration curves of steel, non-sinusoidal vibration function not in using, the other production control systems after multiple failures, processing time is longer, in order to ensure the system safe, reliable, to be part improvements of the original System.This article is mold in-depth study of the hydraulic system and the non-sinusoidal vibration of Shougang Qinhuangdao2#slab continuous caster formed the basis of writing, by analysing the Shougang Qinhuangdao2#Slab Caster hydraulic vibration control Systems, put forward the improvement solution to optimize the system. First of all, for the production of steel for different needs, determine the non-sinusoidal oscillation curve mold; And then, for the problems found in the course of rehabilitation programs made hardware and software equipment, increase in-line monitoring and data acquisition and analysis system; Finally, the actual site, raise made transformation program of hardware and software, have designed the fuzzy self-tuning PID controller. The simulation results proves the effectiveness of the designed controller. Improved the facilitate the maintenance of the equipment; software control flexible, and reliable; meet the needs of different kinds of steel production, thereby greatly improving the quality of the slab surface. The system obtains a good control effect in the continuous casting process.
