Ferro Almanganese

The main function of the deoxidizer used in steelmaking is to react with dissolved oxygen in molten iron, mainly to generate non-metallic compounds, form precipitates, float to the slag layer, and remove them to obtain pure molten iron.

Aluminum can be used as a deoxidizer, grain refiner and alloy additive in the steelmaking process. Its application forms are aluminum wire (feeding wire method), small aluminum ingot, aluminum ring, aluminum cake (input method), aluminum shot, aluminum Bullets (launching method), aluminum-iron block, aluminum-silicon-barium-iron block (composite deoxidation method), etc. Existing aluminum wires are generally produced by cable factories using primary aluminum ingots by smelting, extrusion or rolling processes, deoxidized aluminum ingots, aluminum rings and aluminum cakes are made by steel plants using other primary aluminum ingots, aluminum silicon ferrosilicon and aluminum Ferrobarium is produced using a submerged arc furnace.

A considerable amount of scrap aluminum can be produced during the production and use of aluminum. The aluminum content specified in the steelmaking aluminum ingot standard is lower than that of primary aluminum ingots. Therefore, scrap aluminum can be used to make steelmaking deoxidizers, and the scrap aluminum Recycling is of great significance.
