Synthesis of refining agent of aluminum deoxidation and slag has effect. Aluminum slag particle size uniformity, maintained at between 15-50mm and hardness of single load 75 kg, the most important is the observation of aluminium slag balls content uniformity of ingredients, often with a strong mixing pressed alumina slag balls content of various physical and chemical changes of uniform and stable, using the same, and does not appear to float. When making steel inputs can be used as a reducing agent in early coming off free oxygen in steel, plus it can quickly become covered in liquid slag surface air.

Aluminum slag joined comes in two forms: one is the electric stove in tapping as deoxidizer and deoxidizer while adding to other classes will be reduced to within the control of dissolved oxygen in steel; the second is added when package arrived in LF ladle refining of molten steel in order to adjust the composition of slag, as soon as possible to quickly strip off residues of oxygen to form appropriate refining slag systems.

Real-world production applications:

1,Electric furnace process to join. Steelmaking final deoxidation agent in aluminum slag and silica, calcium, barium, based on end-point carbon content reducing agent addition: aluminium slag 0.5-1.0kg/t; SI-CA-BA, 2.0-3.0kg/t. Order of admission: steel up to 20T to ladle joined silicon, calcium, barium, aluminium slag, tapping time greater than 110 seconds, a steel slag is strictly prohibited.

2, LF refining process. When you refine, adjust ingredients according to the composition of molten steel and slag and slagging agents for aluminium slag, 50-100kg; ferro-silicon carbide powder powder for 20-30kg. 15-25kg-aluminates the sand.

3, Desulfurization. Aluminum slag slag speed, high efficiency, refining slag samples in just 15 minutes you can turn white, desulfurization and quite favorable to inclusion.
