The Establishment Of Simulation Mould Oscillation State Measurement System And Data Analysis In Continuous Casting

This paper present analysis of mould friction (MDF) and establishment of simulation mould oscillation state measurement system.MDF is an important factor which describes the complicate heat-mechanic behaviors in mould, which relate to the quality defects of billet and breakout and some other abnormal phenomena. The measurement and analysis of MDF online data are important, in order to get the relation of MDF with technique parameters and abstract useful information for producing, it is very meaningful for improving the quality of the billet and choosing mould powder and predicting breakout and more productivity. This paper's first part discussed the influence factors of MDF such as mould powder, slab width, pouring temperature, oscillation frequency, negative time and negative strip ratio based on gathering the calculating and monitoring methods of MDF.The technique of mould oscillation is one of the key factors about continuous casting. With the development of near net shape and high performance techniques, the quality defects of billet and breakout and some other questions appears under high casting speed, and it acquire more about billet quality and control of casting process. The measuring of oscillation state can master the working state of device, finding the relationship between deviations and oscillation parameters, and also can judging system abrasion and leading system faulting. In second part of this paper, the simulation mould oscillation state measurement system was designed, by constructing relate hardware and designing the software based Visual C++ platform, the system realized online collecting and calculating about the oscillation parameters, and also can display the parameters. The system performed well in both collecting and calculating and other function through the experiment results.Moreover, in order to explore the relationship between deviations and oscillation parameters, the analysis of oscillation state data which based on hydraulic device was made, which could provide the technique assistant for calculating and analyzing oscillation parameters.
