Resource utilization of aluminum ash:
Can be used as steel-making refining agent: use aluminum ash to prepare calcium aluminate;
Prepare refractory materials: aluminum ash Contains a large amount of alumina, making it a potential raw material for the production of refractory materials;
Other uses: using aluminum ash and silicon slag as raw materials to synthesize X-type zeolite molecular sieves in sodium hydroxide solution; it can also be used as silicon Aluminum alloy, the aluminum recovery rate is 98.4. This technology reduces the production cost of aluminum-silicon alloy and realizes the comprehensive utilization of various wastes;
Aluminum ash is composed of metallic aluminum, alumina, nitride The mixture of aluminum, salt and other components is a rich resource. In view of the increasingly clear regional and concentrated development characteristics of my country's aluminum industry, a large-scale integrated aluminum ash treatment plant will be established in the future to centrally process aluminum ash in the region and realize the transformation from "low-efficiency and decentralized utilization" in the past to "high-efficiency and large-scale utilization". It is the only way for the development of the industry. At this stage, the cost of aluminum ash treatment is high and some companies cannot afford it. Therefore, the development of low-cost harmless treatment technology or high value-added resource utilization technology will be a key strategy to solve the problem of aluminum ash disposal. In addition, increasing the development of aluminum ash treatment engineering equipment, improving the technical level of aluminum ash treatment industrial scale, and promoting the green and healthy development of the aluminum industry are also difficulties that need to be overcome in future aluminum ash treatment.
It would certainly be good if every manufacturer that handles aluminum ash could achieve a technological breakthrough, but the way to truly realize the pollution-free treatment of aluminum ash is to prepare it into refractory materials: using aluminum The preparation of calcium aluminate from ash, that is, the sintered calcium aluminate refining slag, can greatly shorten the steelmaking time and reduce the smelting cost. However, the preparation of calcium aluminate has an ingredient threshold. It does not mean that you can just dump a cart of aluminum ash. It can be used to make calcium aluminate, which is similar to a deoxidizer. The formula calculation APP can greatly help you realize the freedom of ingredient calculation. Enter the aluminum powder ingredient content in your hand into the raw material library, and then according to the customer’s ingredient requirements, Calculate the ratio and get the ratio results in three seconds. It also provides a variety of production plans with better prices and production plans closest to the required ingredient content, helping you solve the production problem of raw material ratio calculation first!
