矿热电炉电极埋入深度控制方法
摘要：
本发明公开了一种矿热电炉电极埋入深度控制方法，该方法包括获取第一和第二电流/电压原始参数；对实际电极电流采样，以获得采样电流/电压参数；确定所述采样电流/电压参数超过第二电流/电压原始参数，对电极埋入深度进行调节；或者确定采样电流/电压参数超过所述第一电流/电压原始参数，但未超过第二电流/电压原始参数，将第一电流/电阻原始参数和第二电流/电压原始参数之间的用于电极埋入深度开始进行调整的多个电流设定值与采样电流/电压参数分别进行比较，在计时累加值超过时间设定值后，对电极埋入深度进行调节。因此，本发明通过提供一种矿热电炉电极埋入深度控制方法实现利用三步偏差时间域来对电极埋入深度进行调节。
摘要（英）：

The invention discloses a control method of the embedding depth of an electrode into an ore-smelting electric furnace, and the method comprises the steps of obtaining a first current/voltage original parameter and a second current/voltage original parameter of the electrode; sampling the actual electrode for obtaining a sampling current/voltage parameter; regulating the embedding depth of the electrode when the sampling current/voltage parameter is determined to exceed the second current/voltage original parameter; or respectively comparing a plurality of current set values for starting the adjustment of the embedding depth of the electrode between the first current/voltage original parameter and the second current/voltage original parameter with the sampling current/voltage parameter when the sampling current/voltage parameter is determined to exceed the first current/voltage original parameter but not exceed the second current/voltage original parameter, and regulating the embedding depth of the electrode when the accumulative time exceeds the time set value. Therefore, the invention provides the control method of the embedding depth of the electrode into the ore-smelting electric furnace, thereby realizing the regulation of the embedding depth of the electrode by utilizing three-step derivation time domain.
