Research On Conticaster Hydraulic System Breakdown Diagnosis

The continuous casting is one kind of advanced production craft, it substituted for the former molten steel die casting, escaped the spindle, soaking, the cogging combination craft. Therefore, in aspects and so on energy consumption, product quality, production efficiency, all has the superiority. The conticaster is processes directly the molten steel the billet the complete set of equipment, the conticaster as a result of the implementing agency disperser surface broad, the transmission power big, the working conditions wicked inferior and widely uses the hydraulic system to carry on the transmission and the control. But its hydraulic system breakdown diagnosis and the service are a complex empirical work, needs to apply the massive unique expert experience and the diagnosis strategy, can solve the complex breakdown diagnosis problem effectively.The hydraulic shake table is the modern tube blank conticaster important equipment, but conveniently the hypothesis and the change profile, the oscillation amplitude, the frequency, can realize the non-sinusoidal vibration, but satisfies the tube blank continuous casting craft enormously the need, has mechanical vibrations no superiority.At present, the conticaster hydraulic system breakdown diagnosis mainly is depends upon serviceman's inspection and the thought activity. The serviceman depends on own sense organ or the instrument test understood the system the breakdown, acts according to own knowledge and the experience again, with the aid of in the material, the handbook carries on the analysis inference, from the qualitative analysis to the quantitative analysis determined the breakdown the spot and the reason, finally carry on the repair. In this work process, serviceman specialized knowledge and experience decisive function. If runs into the serviceman who the specialized knowledge and the experience all lack, can lengthen the operating time, the increase service work load, reduces the working efficiency, even the breakdown is unable to remove, delays the work.The breakdown diagnoses the expert system is an artificial intelligence diagnosis new research area, simulates human's intelligent activity using the computer program, uses the knowledge expression, the knowledge inference technology achieved the human expert solves the question level, already by domestic and foreign widespread applications in each kind of breakdown diagnosis. Therefore, the organization and experiences using the expert, develops the practical breakdown diagnosis system, without doubt has the important project practical value.This topic is for the purpose of take the tube blank conticaster hydraulic system and the hydraulic shake table as the object of study, reorganizes the hydraulic pressure breakdown domain expert's useful knowledge and the skill and the books material, carries on the analysis and processing to its common hydraulic pressure breakdown, simultaneously uses the computer technology, uses development kit Visual BASIC to assemble to the computer in, forms a tube blank conticaster hydraulic system breakdown diagnosis system software. When the user needs, may use the computer the transfer to solve the actual problem as necessary, the realization hydraulic system breakdown diagnosis automation or the semiautomation, by enhances the breakdown diagnosis and the maintenance working efficiency greatly.This system may as necessary collect and reorganize this domain expert's experience and the knowledge, Carries on the supplement and the maintenance to the system, causes the breakdown diagnosis scientific, the modernization,;the intelligence,plays the human expert's role, causes the computer, the machinery and the hydraulic pressure technology unifies organically in together.
