Abstract

The invention relates to the technical field of direct position measuring, and discloses a device and method for measuring an electrode position of an ore heating furnace. The device comprises at least one magnetic field sensor and an electrode current measuring component which are arranged on an ore heating furnace wall. A data acquisition processor is connected with both the magnetic field sensor and the electrode current measuring component respectively. A controller is connected with the data acquisition processor. According to the device and method for measuring electrode position of the ore heating furnace, the magnetic field sensor is arranged on the ore heating furnace wall, and can measure instantaneous magnetic field strength generated by the ore heating furnace internal electrode current, and therefore the specific position of the electrode can be reckoned based on the magnetic field strength generated by the electrode current under a real-time work condition.

Description

technical field [0001] The invention relates to the technical field of direct position measurement, in particular to a device and method for measuring the position of a submerged arc furnace electrode. Background technique [0002] The submerged arc furnace is an industrial submerged arc furnace with a power of tens of thousands of kilowatts. Its working safety, stability and energy consumption level all depend on the working position of the submerged arc furnace electrode in the furnace. The submerged arc furnace works under the condition of electric arc, the temperature in the crucible area is very high, and the furnace charge is a mixture of various solid minerals, the interface is not fixed, and at present, the submerged arc furnaces in all countries in the world do not have a direct measurement device for the electrode position, so the submerged arc furnace Furnace operation has always been based on experience to judge the working position of the electrode, and accident...
