In pyrometallurgical copper smelting, the reverberatory furnace is a crucial core piece of equipment.
Reverberatory furnace copper smelting relies on the principle of thermal radiation to achieve high-temperature smelting.
The combustion of fuel inside the furnace generates high-temperature flames and flue gas, which are reflected by the refractory lining of the arched furnace roof and walls, radiating heat evenly to the surface of the furnace charge.
Reverberatory Furnace Copper Smelting Process
During smelting, copper concentrate, roasted sand, and fluxes such as quartz and limestone are added to the furnace. A chemical reaction occurs at temperatures above 1400℃, fully melting the minerals and ultimately separating copper matte and slag. So This achieves the initial enrichment and purification of copper.
Furnace Body Maintenance
High-temperature smelting places extremely high demands on furnace body protection. So The furnace inner wall must be constructed using high-strength refractory bricks and refractory castables. Generally speaking, Magnesia-chrome bricks are typically the first choice. Because Magnesia-chrome bricks have excellent cold-pressing strength, refractoriness, and other core indicators, ensuring long-term stable operation of the furnace and extending the equipment’s service life.
