| titleOfInvention | Operating method of flash smelting furnace for nonferrous metal smelting |
| abstract | (57) [Summary] [PROBLEMS] In the operation of a flash smelting furnace for sulphide concentrate smelting, fluctuations in the Kawa grade and the melt temperature based on changes in the composition and charge amount of the raw sulphide concentrate are suppressed and are always stable. The present invention provides a method of operating a flash smelting furnace for nonferrous metal smelting that can continuously perform the above operation. SOLUTION: In the operation of a flash smelting furnace for smelting non-ferrous metals from non-ferrous metal sulfides, the Kawa grade and the melt temperature in the melt are periodically measured, and the measured values and target values are compared. Comparing the differences, when changing the blowing amount of auxiliary fuel and reaction air or oxygen set in advance in an equilibrium manner according to the absolute value of the deviation value, the absolute value of the deviation value exceeds a certain limit value The auxiliary fuel and the reaction air or oxygen are blown with a larger change amount than the theoretically calculated change amount in accordance with the deviation value as the value becomes larger and the value becomes larger. The operation is performed without changing the injection of fuel and reaction air or oxygen. |
