“…A major benefit of HRC arises from the opportunity to use remote lead-through control strategies based on a Cyber-Physical System 16 , possibly using a model-based display, which obviates the necessity of a human operator being physically present in a hazardous operational site, such as dusty, high-pressure or high-temperature environments [94]. For example, in the context of coating industry, the application of a lag-removing robot for zinc pot on a hot-dip galvanizing line has been reported in [95]. HRC systems employed in RAD applications may take substantial advantage of gesture recognition technologies for a more smooth and natural performance, through which the human operator guides the robot throughout the course of performing the relevant tasks.…”

Despite their contributions to the financial efficiency and environmental sustainability of industrial processes, robotic assembly and disassembly have been understudied in the existing literature. This is in contradiction to their importance in realizing the Fourth Industrial Revolution. More specifically, although most of the literature has extensively discussed how to optimally assemble or disassemble given products, the role of other factors has been overlooked. For example, the types of robots involved in implementing the sequence plans, which should ideally be taken into account throughout the whole chain consisting of design, assembly, disassembly and reassembly. Isolating the foregoing operations from the rest of the components of the relevant ecosystems may lead to erroneous inferences toward both the necessity and efficiency of the underlying procedures. In this paper we try to alleviate these shortcomings by comprehensively investigating the state-of-the-art in robotic assembly and disassembly. We consider and review various aspects of manufacturing and remanufacturing frameworks while particularly focusing on their desirability for supporting a circular economy.

“…Therefore, this study only focuses on the continuous hot-dip galvanizing process. In production, hot-dip galvanizing slag is generally removed by manual or mechanical methods since it harms the surface quality of the galvanizing layer [9][10][11][12]. Approximately 12% to 15% of metal zinc is inevitably carried in the process of fetching slag, resulting in a significant increase in galvanizing costs.…”

The elimination and retrieval of slag produced during the hot-dip galvanizing process are crucial in reducing plating defects and enhancing economic efficiency. Hot-dip galvanizing slag can be separated and purified efficiently by using graphite carbon felt filtration in a supergravity field. The effects of the gravity coefficient (G), separation temperature (T), and separation time (t) on the separation efficiency were investigated. Under the optimal conditions as G = 300, T = 460 °C, and t = 120 s, these conditions yielded filtered zinc with 0.022 wt% Fe and 1.097 wt% Al. The separation efficiencies achieved were 87% for the acquisition ratio of filtered zinc (AZn), 93.67% for the recovery ratio of zinc (RZn), and 96.01% for the loss ratio of iron (LFe). Based on these laboratory findings, an amplified centrifugal separation apparatus was conceptually designed for future online separation and recycle of zinc slag on an engineering scale. The filtered zinc obtained from this apparatus contained 0.027 wt% Fe and 1.844 wt% Al, while the recovery ratio of zinc (RZn) and the loss ratio of iron (LFe) achieved 85.97% and 95.47%, respectively.

“…Therefore, in the zinc smelting process, it is urgent to develop an efficient and innovative automatic slagging mechanism. In recent years, relevant scholars have studied and proposed several kinds of slagging mechanisms with different characteristics for different working conditions [1]- [6]. In this paper, a new type of slagging mechanism is proposed, which has the advantages of novel structure and stable operation, and can realize the rapid and effective removal of zinc slag.…”

To solve the problems of difficult slag picking, danger, and low efficiency of manual slagging in the casting process, a double-cam connecting rod slagging structure is designed for the zinc ingot production line. First, a set of linkage mechanisms for slagging action is designed using geometric formulas, which are applied to the design of the overall contour of the cam through Excel and SolidWorks' Cosmos/Motion plug-ins, and then the kinematics simulation is carried out using Adams software. Finally, the simulation results show that the double cam connecting rod slag structure has stable work, reliable structure, no obvious vibration shock, and the mechanical structure meets the requirements in the process of simulating the removal of zinc slag.
