ESTIMATING APPARATUS FOR MELTING RATE OF SCRAP AND ELECTRIC ARC FURNACE OPERATION APPARATUS HAVING THE SAME AND ESTIMATING METHOD FOR MELTING RATE OF SCRAP AND ELECTRIC ARC FURNACE OPERATION METHOD USING THE SAME

摘要

The present invention relates to a scrap melting rate determination device, an electric furnace steelmaking operation device having the same, a scrap melting rate determination method, and a steelmaking operation method using the same. A melting state of the scrap in the electric furnace main body is photographed in real-time with a thermal imaging camera and a melting rate of the scrap is calculated with the photographed image, a power source unit is reduced and a shortened operation time through change of a power input pattern is shortened by analyzing a correlation between the power input amount inputted in real-time and the scrap melting rate and thus maximizing an efficiency of the steelmaking operation of the electric furnace, a recovery rate is improved and a water leakage advance measure of a WCP water cooling jacket is possible, and operation loss is minimized during water leakage of the WCP water cooling jacket and during operation accident with a rapid response, thereby preventing water leakage of the WCP water cooling jacket through an in-house observation of the furnace.
