Problems solved by technology

When the electrode is pressed and released, the operator cannot predict the roasting temperature and quality of the electrode. It often occurs that the electrode roasting quality does not meet the requirements and the electrode is pressed and released in advance, resulting in soft breakage of the electrode, or the electrode is not pressed and released in time, causing the electrode to over-roast the iron sheet.

Abstract

The invention discloses a method for measuring the roasting temperature of a self-baking electrode of a calcium carbide furnace and controlling slipping of the electrode. The method has the advantages that more than four temperature sensors are mounted at corresponding positions of the electrode, accordingly, the roasting temperature of the electrode is measured in real time, the roasting quality and the speed of the electrode are computed and judged, slipping operation is automatically controlled according to the roasting quality and the speed, the smelting requirement on the length of the electrode is met assuredly, accidents of soft breakage of the electrode and overburning of a coiled iron sheet are stopped, and purposes of improving running efficiency of the calcium carbide furnace, reducing smelting power consumption and enhancing yield are achieved.

Description

technical field [0001] The invention relates to a measurement and control device and method for the roasting quality of self-baking electrodes in a calcium carbide furnace. Background technique [0002] Calcium carbide furnace is a kind of submerged arc furnace series. The smelted product is calcium carbide. The core theory of its smelting is to form a directional high-temperature ion flow-arc through ionized air, convert electrical energy into heat energy, and provide a high enough temperature for the reduction reaction. field. [0003] The length of the electrode depends on the balance between the electrode firing rate and the electrode tip consumption rate. During the smelting process, with the continuous rise of the molten pool liquid level (or slag level) at the bottom of the furnace, the charge of the furnace is often lowered, the electrode tip is moved up due to burning and the conductivity of the molten pool changes, so it is necessary to adjust the electrode in a t...
