Design Of Continuous Casting Level Control System For TISC2#Continuous Casting Machine

Metallurgical industry plays a mainstay role in the national economy. In the metallurgical industry, the production of iron and steel is its important components and continuous casting industry is one of its key taches. How to heighten the productivity and improve the quality of continuous casting has become a hot topic in the fields of steel research. The stability of the mould level in casting process is very meaningful to improve the quality of iron and steel, reduce accidents, and ensure production quantity.Therefore, how to stabilize the mould level under the influence of uncertain factors during the casting process is one of the most critical problems to be solved. Based on the technology analysis of the casting process of2#Continuous Casting Machine in Tianjin steel group Co., LTD, the various uncertain factors influencing the mould level are qualitatively analyzed, such as characteristics of the stopper rod, materials of stopper rod and nozzle, cast speed, tunish liquid steel weight, nozzle clogging, and the submerged nozzle cracks. The hardware configuration and control strategies of the mold level control system in2#Continuous Casting Machine are discussed in detail. Furthermore, the limitations of currently adopted PID control strategy are analyzed and pointed out. Due to the existed problems of the mould level control, optimize the detection link with eddy current detecting method instead isotope method. And based on the establishing mould level system model, using composite fuzzy PID control method of adjusting the stopper opening, realize the intelligent control of mould level. Through the simulation test, this designed system improve the steady precision, and will yield satisfactory industrial application results.
