Drossing fluxes for aluminium molten furnace casting refining
1.Technical introduction: When aluminum or aluminum alloy is melted or refined, a lot of scum is produced, and when mixed with aluminum, more scum is produced. The scum is easy to stick to form a block, absorb a large amount of molten aluminum, and it is difficult to operate when removing the slag, and a large amount of molten aluminum is taken away, resulting in losses. With the use of slag, these problems are solved.
2.Product features and usage: Features:
a.Change the composition and properties of the slag, so that the scum is loose and easy to clean and scrape out.
b.Remove the oxide scale and impurities in the molten aluminum, clean the slag thoroughly, and clean the molten aluminum to ensure the quality of the castings.
3.The slag is loose, which can significantly reduce the loss of molten aluminum, which can reduce the loss of molten aluminum by 0.3 to 0.5 kg per ton.
1.Use in the furnace: According to the smelting and doping of aluminum alloy, the general dosage is 0.1-0.3% of the weight of the molten aluminum (that is, adding 1-3 kg of drossing flux per ton of molten aluminum).
2.Use outside the furnace: The aluminum slag removed from the furnace can be heated by a drossing flux to achieve a good separation effect of the aluminum slag. a little more.
3.Application areas, market prospects and industrialized production conditions: It is mainly used for smelting pure aluminum, aluminum alloy and recycled aluminum, to remove the surface dross inside the molten aluminum, and to absorb the slag inclusions near the surface layer, and it can also be used for frying slag. It is one of the purification fluxes that must be used in the smelting of aluminum and aluminum alloys. The market demand is large and the application prospect is broad. The production equipment and process of aluminum drossing flux are relatively simple, mainly drying furnace, crushing equipment, stirring and mixing equipment, and simple packaging equipment. The equipment investment is small, and the production process is easy to master.
4. Analysis of Economic Benefit and Environmental Evaluation: The raw material cost per ton of aluminum drossing flux is about 900-1,000 yuan/ton, and the average market price is about 2,000-2,300 yuan/ton. The cost of raw materials fluctuates with market prices and changes due to different production batches. The raw material market is easy to buy, and the mass production forms a scale, which has good economic benefits. The raw materials used in the production of slagging agent are non-toxic common chemical raw materials, and there is no discharge of sewage, waste gas and waste residue in the production process, and no pollution to the environment.
