摘要： The present invention discloses a control method for continuous casting steel pouring, wherein: Step one: measuring and reading a steel ladle pouring position signal by a steel ladle position sensor (14) mounted on a turntable of a steel ladle; Step two: judging whether the pouring of the steel ladle (1) has begun therein by a steel pouring optimization control computer (13); Step three: feeding a data of a steel slag measurement sensor (2) mounted above a steel ladle sliding nozzle (15) to an inferential controller; Step four: in the inferential controller, conducting a comparison between the read data of the steel slag measurement and the manually set value of steel slag, and back to the former step if the measured value of the steel slag measurement is smaller than the manually set value of steel slag; if the current measured value of the steel slag measurement is greater than the manually set value of the steel slag, outputting and feeding a cylinder control variable to a PI controller; Step five: conducting a comparison between the cylinder position signal output by the inferential controller and a cylinder position signal actually measured and a calculation in the PI controller, and an output control of the cylinder driving unit (5) drives the cylinder (3) to move, thus reducing the opening degree of the sliding nozzle (15) of the steel ladle.
摘要翻译： 本发明公开了一种连续铸钢浇注的控制方法，其特征在于：第一步：通过钢包浇注位置传感器（14）测量和读取钢包倾倒位置信号，钢包位置传感器（14）安装在钢包的转台上; 第二步：判断钢浇注优化控制计算机（13）是否开始浇注钢包（1）; 步骤三：将安装在钢包滑动喷嘴（15）上方的钢渣测量传感器（2）的数据馈送到推算控制器; 第四步：在推算控制器中，对钢渣测量的读数据和钢渣的手动设定值进行比较，如果钢渣测量值的测量值小于手动设定值，则返回前一步骤 钢渣价值; 如果钢渣测量的当前测量值大于钢渣的手动设定值，则向PI控制器输出和供给气缸控制变量; 第五步：通过推算控制器输出的气缸位置信号与实际测量的气缸位置信号和PI控制器中的计算进行比较，气缸驱动单元（5）的输出控制将气缸（3）驱动到 移动，从而减小钢包的滑动喷嘴（15）的开度。
