Characteristics of continuous wire rod rolling and precision rolling system

The demands of users for closer dimensional tolerances and improved metallurgical properties in wire rod products prompted the research and development of sophisticated dimensional and material temperature control technologies in continuous rolling. To cope with these problems, first, we have developed a nonlinear simulation model for calculating interstand tension, height, width, temperature, load and torque in steady state, transient state and influence coefficient of continuous rolling. The examples of simulation results were in good agreement with the measured values. As an example, material temperature of 2 block mill was simulated using this model. Second, as applications of the simulation model, we have developed multivariable control systems. Third, we have developed a precision rolling system (NT Block Mill Automatic Gauge Control).
