Abstract
A control method and apparatus for continuous casting steel pouring are provided, wherein the amount of the molten steel flow of the ladle is controlled, thereby improving the yield of the molten steel and decreasing the production cost.
Claims7
A control apparatus for continuous casting steel pouring, comprising:
- a steel ladle, a sliding nozzle, a steel ladle long nozzle, a tundish, a sliding nozzle driving cylinder, a cylinder driving unit, an inferential controller comprising a unit for receiving data, analyzing the received data, computing at least one value based on the analyzed data, and output a control function, and a PI controller, wherein the steel ladle long nozzle connects the steel ladle and the tundish;
- wherein further, the inferential controller is configured to:
- obtain a steel slag amount signal from a steel slag measurement sensor;
- determine that the steel slag amount signal is greater than a manually set steel slag amount value;
- in response to the steel slag amount signal being greater, determine a cylinder control signal;
- and
- send the cylinder control signal to the PI controller;
- wherein the PI controller is configured to determine a degree of opening of the sliding nozzle based on the cylinder control signal and outputs a second signal to the cylinder driving unit based on the determined degree of opening of the sliding nozzle;
- and
- wherein, upon receipt of the second signal, the cylinder driving unit is configured to adjust the degree of opening of the sliding nozzle based on the second signal by sending one or more third signals to the sliding nozzle driving cylinder.
