Anode furnace (refining furnace) is also called rotary refining furnace

Anode furnace (refining furnace), also called rotary refining furnace, is suitable for refining molten blister copper.

The refining operations are feeding, oxidation, reduction, and casting, and the product is anode plate. There is a furnace opening on the cylindrical furnace body for charging and copper discharge. There is a small amount of tuyere on the side of the furnace body. High-pressure air is introduced into the oxidation period, and reducing agent is introduced into the reduction period. When the tuyere is not in operation, it is placed in the furnace. Above decent, when performing redox operations, tilt the furnace so that the tuyere is buried in the melt.

Notes on the use of anode furnace:

First, the furnace temperature of the anode furnace is higher than 1350 °C. Unlike the fixed furnace, there is no fixed molten pool (slag) line. The erosion of the slag and the erosion of the molten metal almost involve more than 2/3 of the inner surface of the furnace;

Second, because the furnace needs to be rotated frequently, the masonry and the steel shell must be in close contact, and the static friction between the masonry and the steel shell must be increased to overcome the rotational torque to maintain the stability of the masonry, so there is no light insulation layer. ;

Third, in order to reduce the load of the masonry (to reduce the load of the support device and reduce the power consumption of the transmission), the thickness of the masonry layer should be reduced as much as possible under the conditions that the surface temperature of the steel shell allows (300 ° C).

In addition, in the two impact areas of feeding, considering the influence of temperature fluctuations during feeding, fused semi-rebonded magnesia-chrome bricks are also selected in this part. Due to the convenience of structure and construction, the combustion port and flue gas outlet are knotted with magnesia-chromium ramming material.
