Abstract

The invention provides a method for detecting the length of a calcium carbide furnace electrode. The method comprises the steps: obtaining a non-linear prediction model of electrode consumption according to a model training sample set, wherein electrode temperature T, electrode power P, a furnace charge ratio R and calcium carbide output G are sample input variables, and the electrode consumption is a sample output variable; determining electrode consumption in a current working condition according to the non-linear prediction model of electrode consumption; and determining the length of an electrode according to the electrode consumption in the current working condition. The method can monitor the position changes of an electrode in real time and then guide pressing and releasing for electrodes, so the pressing and releasing amount for electrodes can be accurately controlled, and electrodes are made to work in a balance manner. The method guarantees stable production and energy-saving operation of a calcium carbide furnace.

Description

technical field [0001] The invention relates to the field of industrial control information, in particular to a method and system for measuring the length of an electrode of a calcium carbide furnace. Background technique [0002] Calcium carbide furnace is the main equipment for the production of calcium carbide. It mainly heats the materials in the furnace, such as quicklime and carbon, through the submerged arc electric heating of the electrodes and the resistance electric heating of the materials, so that the materials react to form calcium carbide. [0003] The electrodes commonly used in calcium carbide furnaces include self-baking electrodes, graphite electrodes or carbon electrodes. The electrodes transmit large currents to the furnace, and arcs are generated at the ends of the electrodes, which then convert electrical energy into heat energy. Due to the extremely high temperature generated on the arc , The electrode tip is sublimated, resulting in the electrode bein...
