This paper analyses the influence of graphite reinforcement, load and sliding speed with constant sliding distance on tribological behavior of A356 aluminum matrix composites reinforced with 10 wt.% silicon carbide and graphite using the Taguchi design. Hybrid composites were produced in the compo-casting process. Tribological tests were performed on a block-on-disc tribometer where the weight percentage of graphite has three variations (0, 3, and 5), as well as load (10 N, 20 N, and 30 N) and sliding speed (0.25 m/s, 0.5 m/s, and 1 m/s), with sliding distance of 300 m. The wear of the composite is investigated under dry sliding condition. The specific wear rate was analyzed using Taguchi method with the aim of finding the optimal parameters. By applying analysis of variance, it was determined that the best tribological properties has A356/10SiC/3Gr hybrid composite. It was also found that the greatest impact on specific wear rate has load with the percentage effect of 69.163%, then sliding speed with 14.426% and the interaction between wt.% graphite and load. The dominant wear mechanism is adhesive wear as confirmed by scanning electron microscopy with energy dispersive spectroscopy (SEM-EDS).

“…Therefore, the use of harmlessly treated SAD for the production of refractory materials can not only help to realize the recovery of secondary resources, but also reduces the production cost of refractory materials. Li et al [123] successfully prepared high-alumina refractory materials by sintering SAD with the main crystalline phase of MgAl 2 O 4 and small amounts of CaAl 2 O 4 at 1530 • C. Adeosun et al [124] used SAD and kaolin as raw materials to prepare refractory bricks, investigating the influence of SAD content on their performance. The results revealed that the prepared refractory bricks exhibited exceptional properties within a mass fraction ranging from 40% to 70% for SAD, achieving a remarkable refractoriness of up to 1200 • C. Liu [125] et al prepared lightweight refractory materials with pretreated SAD and fly ash as the main raw materials.…”

The production process of the metallurgical industry generates a significant quantity of hazardous waste. At present, the common disposal method for metallurgical hazardous waste is landfilling, which synchronously leads to the leaching of toxic elements and the loss of valuable metals. This paper presents a comprehensive review of the research progress in the harmless treatment and resource utilization of stainless steel dust/sludge (including stainless steel dust and stainless steel pickling sludge) and aluminum ash (including primary aluminum ash and secondary aluminum dross), which serve as representative hazardous wastes in ferrous metallurgy and nonferrous metallurgy, respectively. Additionally, the general steps involved in the comprehensive utilization of metallurgical hazardous waste are summarized. Finally, this paper provides a prospective analysis on the future development and research trends of comprehensive utilization for metallurgical hazardous waste, aiming to offer a basis for the future harmless, high-value, resource-based treatment of metallurgical hazardous waste and the realization of industrial applications in China.

“…It was found from their studies that the recovery of aluminium is about 10% through this process. Adeosum et al [15] made refractory bricks by using aluminium dross waste and kaoline in different proportions. After evaluating the various properties such as the firing temperature, bulk density, thermal shock, permeability, loss on ignition, shatter index, shrinkage, porosity and thermal conductivity, it was found that the aluminium dross waste can be used in manufacture of refractory bricks.…”

Recycling and reutilization of industrial waste and by-products are subjects of great importance today in any sector and more so in cement and concrete technology. Aluminium is the most widely used nonferrous metal in the world. During the production of aluminum, a huge amount of waste is produced, known as dross, which is used for recycling and re-extraction of remaining aluminum. The dross is found to be toxic and hazardous waste for the environment and hence recycling or locking up of this waste is very crucial. The dross is mainly composed of oxides and aluminum and in the recycling, salt process is employed to recycle aluminum from the dross. This paper examines various forms of production of aluminum scrap, treatment methods, and typical application of aluminum residue. Brief description on waste management aspects is provided in this paper. The important observations made from the review studies are summarized.
