Research on intelligent lifting model and accuracy of ladlefor RH refining
RH refining technology,as an important link in the steel production process,its intelligence has become a research hotspot in the industry.The intelligent c technology of ladle is the key to achieving efficient and stable production of RH.The intelligent lifting model for steel ladles have been established and the factors affecting the measurement accuracy of radar rangefinders have been analyzed.The radar damping coefficient is 1.5 Ns/m,and the running speed of the steel ladle car when passing through the radar is 10 m/min.The center of the steel ladle passes through-1 000 mm to 1 000 mm directly below the radar.Taking the average of real-time data measured by all radars,the radar rangefinders have the highest accuracy.The error between the automatic lifting height calculated by the intelligent lifting model of the ladle and the actual lifting is less than 5%,which can be used for the intelligent lifting process of the ladle in RH refining process.
