Because of disadvantages of converter steelmaking with semi-steel in Panzhihua Steel, such as slow-footed slag forming, low rate of dephosphorization, high rate of rephosphorization after converter smelting, studies on increasing dephosphorization rate have been carried out. These studies comprise the optimization of slagging process, oxygen supply, bottom argon supply, end-point control of converter smelting, and so on. With these countermeasures, the rate of dephosphorization has been increased obviously. The results show that the average rate of dephosphorization is above 90% with single-slag process during converter smelting. Otherwise, content of phosphorus at the end-point of converter smelting can be controlled below 0.007%, and rephosphorization rate after converter smelting can be controlled below 0.003%, which meets the requirement of [P]≤0.010% for steel products.

Point Control

An alternative approach to the control of nonrigid, distributed parameter systems is presented. Transfer functions that relate the response of points on the system to a controlling force or torque are used in place of ordinary differential equations, which represent an approximation to the system dynamics. The implications of this “point control” approach are discussed with regard to plant modeling accuracy, uncontrolled regions, open-loop and closed-loop control strategies, system identification, and feedback estimation. Sample optimal control histories are illustrated for a single-link manipulator member with end load.
