Document Type and Number:
Japanese Patent JP2023139359
Kind Code:
A
Abstract:
To provide a temperature raising method capable of shortening a temperature raising time without generating local overheating in a furnace, by smoothly igniting a shaft burner, and stabilizing a burner flame even after ignition of the shaft burner.SOLUTION: A method for raising a temperature at the time of startup of a smelting furnace for smelting non-ferrous metals, such as a self-melting furnace used in a smelting process of pyrometallurgical copper smelting, wherein after the inside of the smelting furnace is substituted by air of higher oxygen concentration than the air introduced via a gas introduction part formed of a window box for example in the smelting furnace, a burner of the smelting furnace is ignited.SELECTED DRAWING: Figure 1
