Automatic measuring device and measuring method for electrode paste height of submerged arc furnace

Abstract

The invention discloses an automatic measuring device for the electrode paste height of a submerged arc furnace. The device comprises an electrode cylinder and a submerged arc furnace five-layer platform. A paste measuring platform is arranged between the electrode cylinders on the submerged arc furnace five-layer platform. A fixing support is arranged on the paste measuring platform. Limiting stop blocks are welded in the middle of the fixing support. A rotating motor is arranged on the upper portion of the fixing support. A clamping fixing block is welded to the top of the rotating motor. Arotating parallel arm is fixedly installed on the clamping fixing block. Vertical fixing stop levers are welded to the lower portion of the rotating parallel arm. Laser range finders are arranged at the end of the rotating parallel arm. Electrode paste columns are installed in the electrode cylinders. The device is simple in structure, convenient and rapid to use, accurate in measurement and capable of achieving standardized operation. In actual use, the measuring device can ensure that the point positions measured each time fall on the central point position of an electrode shell and the other two point positions symmetrical to the central point position, and can measure the height values of the three paste columns at the same time, so that accurate measurement values of the paste columnscan be obtained.

Description

technical field [0001] The invention relates to the production field of a submerged arc furnace, in particular to an automatic measuring device and a measuring method for the electrode paste height of a submerged arc furnace. Background technique [0002] At present, in the production process of the submerged arc furnace in China, the electrode is the heart, and the current is input into the furnace through the electrode to generate an arc for submerged arc furnace smelting. The electrode plays the role of conduction and heat transfer. Submerged arc furnace electrodes mostly use self-cultivated electrodes, which can be changed in use, lengthened, shaped, and sintered. The self-baking electrode is composed of electrode paste and electrode shell. The electrode shell is rolled from 2-3mm steel plate. The electrode shell is filled with block electrode paste. It is continuously consumed during the operation of the submerged arc furnace, so it is necessary to continuously add ele...
