Steel Making Additive Ferro Silicon Slag Good Deoxidation Effect
Ferro Silicon Slag
Description:
Silicon slag is a white solid substance separated after desiliconization operation, called silicon slag. Because it contains alumina and alkali, it is usually added back when preparing raw ingredients.

Application:
The task of the silicon slag 60 separation process is to separate the desilicon slurry sent from the desiliconization process to obtain sodium aluminate semen with a desiliconization index, iron-aluminum ratio and floating matter content that meet the process requirements, and then send the semen to carbonic acid decomposition.
The quality of semen is the key to ensuring the quality of the final product, alumina.
Silica slag 45 is a water-containing mixture obtained by alkali fusion, acid leaching, and water dissolution of zircon sand. It is a colloidal polymer with a high water content. It has a light yellow-green appearance, a sponge shape, strong adsorption, and a complex structure. The main ingredients are silicic acid and water, which become acidic after being soaked in water.
