Production and application of silicon slag
DATE：2022-03-29
A white solid substance separated by desilication is called silicon slag. Because it contains alumina and alkali, it is generally returned to the preparation of raw materials mixed in with.
As one of the metallurgical materials purchased in large quantities by manufacturers, silicon slag has irreplaceable advantages. Most people think that silicon slag is the waste of useless ferroalloy residue. In fact, many people in the industry will know that silicon slag is the residual of the original silicon ore after being refined, and it also contains a lot of silicon. Because of the different uses of silicon, there are many kinds of silicon slag, which can be roughly divided into industrial silicon slag, solar silicon slag and semiconductor silicon slag. Silicon slag itself is also very valuable, can be recycled and can be used as a deoxidizer.
The primary USES of silicon slag can be used as deoxidizer and refining of industrial grade silicon, silicon slag as deoxidizer can reduce costs, increase profits, part of silicon slag containing silicon components can also be used for the purification of industrial silicon, silicon slag in the field of DNA is also a "star", because its price is low and contains silicon, Steel manufacturers are more inclined to silicon slag products when purchasing ferroalloy raw materials in steel making, and silicon slag performs equally well in desulfurization, mainly because silicon slag contains a large number of alkaline oxides, which can react with sulfur dioxide to generate sulfate, and its slurry can be used for flue gas desulfurization.
Silicon slag can also be used for steel slag smelting pig iron, ordinary casting, etc. Silicon slag can improve the furnace temperature, increase the fluidity of hot iron, high-quality slag discharge, increase the label, and update the toughness and cutting ability of iterative castings. Stainless steel manufacturers use silicon slag as reducing agent in the process of smelting stainless steel in electric furnace to upgrade efficiency and output
