“…Chips can be recycled using methods like electric arc furnace (EAF) [141][142][143][144][145][146], electroslag remelting (ESR) [147][148][149][150][151][152], vacuum arc remelting [153][154][155][156], vacuum induction melting [136,[157][158][159], electron beam melting [160][161][162][163][164], and plasma arc melting [165][166][167][168]. The various conventional processes for remelting chips generated from diverse materials can be further elaborated for understanding.…”

“…These beams are targeted on the material to be processed. The beam energy converts into thermal energy, as the kinetic energy of the electron is deposited into the target, which leads to the melting of the material [157]. The material is not overheated with electron beams, which results in a high level of purification of metals from gases and metallic or nonmetallic admixtures, and results in the preservation of the structure, chemical composition, and properties of finished metallic ingots.…”

To improve the microstructure and mechanical properties of fundamental materials including aluminum, stainless steel, superalloys, and titanium alloys, traditional manufacturing techniques have for years been utilized in critical sectors including the aerospace and nuclear industries. However, additive manufacturing has become an efficient and effective means for fabricating these materials with superior mechanical attributes, making it easier to develop complex parts with relative ease compared to conventional processes. The waste generated in additive manufacturing processes are usually in the form of powders, while that of conventional processes come in the form of chips. The current study focuses on the features and uses of various typical recycling methods for traditional and additive manufacturing that are presently utilized to recycle material waste from both processes. Additionally, the main factors impacting the microstructural features and density of the chip-unified components are discussed. Moreover, it recommends a novel approach for recycling chips, while improving the process of development, bonding quality of the chips, microstructure, overall mechanical properties, and fostering sustainable and environmentally friendly engineering.

“…With the rapid development of industrial technology in the 20th century [1,2], the medium-frequency induction furnace is widely used in the steelmaking industry [3]. Due to the contactless electromagnetic stirring of melt, the medium-frequency induction furnace improves the mixing and chemical homogeneity of metal in the furnace [4]. In the furnace, an oscillating magnetic field produced by the harmonic current heats up the metal.…”

Based on the chaos algorithm and immune algorithm theory, an adaptive chaotic immune optimization algorithm (ACIOA) with a mutative scale was proposed and subsequently validated by the experiment result in this paper, and then the adaptive chaotic immune optimization algorithm with mutative scale was applied to investigate the performance characteristics of the medium-frequency induction furnace. The obtained results include the effects on the performance characteristics of a medium-frequency induction furnace of the diameter of the heated cylindrical material, the thickness of the crucible wall, the fullness degree of the induction coil, the ratio of diameter to current penetration depth, and the power frequency. The results showed that the optimization algorithm could continuously modify the variable search space and take the optimal number of cycles as the control index to carry out the search. In addition, the suitable ratio of diameter to current penetration depth was between 3.5 and 6.0, and was beneficial to the improvements of in power factor and thermal efficiency. This method had the characteristics of small calculation delay, high anti-noise ability, and high detection rate. Moreover, the maximum errors of KFF, Random, and PSO were 6.4%, 6.2%, and 5.4%, respectively. The improved method had good estimation accuracy and an excellent global optimization. Meanwhile, the suitable ratio of diameter to current penetration depth, the thickness of crucible wall, and power frequency were beneficial to the improvements in power factor and thermal efficiency. Thus, the finding is helpful as a guide to determining the design of a medium-frequency induction furnace, which may be of interest for improvements in performance under different operating conditions.
