Abstract

The invention relates to a non-contact detection and optimum smelting control method for a submerged arc furnace electrode, belonging to the technical field of submerged arc furnace smelting. The method is based on the principle of photoelectric type non-contact detection and is used for detecting the relative length of the electrode. The obtained data is used for describing the loss and the relative length of the electrode. A system model is established according to the relationship set parameters of the current loop and the position loop of the electrode in the process of electrode slippingand in combination with the correlation among the position of a conductive beam, the perpendicularity of the electrode, furnace burden and the current of the electrode, thereby realizing the continuous intelligent automatic production of the submerged arc furnace. The invention has the advantages that the full-automatic intelligent operation of the submerged arc furnace is realized, the labor intensity is reduced, and the product investment cost and the energy consumption are reduced.

Description

technical field [0001] The invention relates to a production process in submerged arc furnace smelting, in particular to a method for non-contact detection and optimal smelting control of electrode relative lengths in the submerged arc furnace smelting process. Background technique [0002] According to its working principle, electric arc furnace can be divided into three categories: direct heating electric arc furnace, indirect heating electric arc furnace and resistance electric arc furnace. Submerged arc furnace is a direct heating electric arc furnace. The coke is catalytically burned to melt the iron ore powder. The charge is actually one of the arc electrodes. In this type of electric arc furnace, the charge directly under the high-temperature electric arc melts instantaneously. If the melting point of the charge is low and the gasification temperature is low, a large amount of charge will be gasified, resulting in a great loss. In addition, because the electrodes o...
