Al2O3 Copper Smelting Furnace

Castable Refractory for natural copper smelting furnace
The natural copper smelting furnace is widely used in converter, horizontal, vertical and horizontal cylinder type, the converter used more.
Copper converter furnace temperature fluctuations, the linling should be used ramming mass and good thermal shock,and should have good resistance to slag,Use more is the magnesium chromium brick or chrome brick, magnesia brick due to nonferrous metal slag resistance and thermal shock resistance, generally have little use.
The outlet area and the slag line part is lined with weak links of converter lining, should adopt direct bonded magnesia chrome brick or magnesite brick masonry;Other parts of the ramming mass lining can be used ordinary magnesia chrome brick, masonry thickness of 300 ~ 500mm.The relevant factors of copper converter ramming mass lining life and smelting method and operation level, the general life of 300 to 500 heats.In order to improve the service life of tuyere ramming mass lining, the ramming mass lining erosion tends to balance, some Western magnesia chrome brick non-ferrous metallurgical plant trial of molten magnesium granules made of magnesia chrome brick and MgO were made of molten magnesium chromium particles for magnesite brick 70%, and magnesia spinel brick and calcium oxide brick, are obtained the good use effect.
