The Aluminum Industry

The influence of the periodicity of diagnostic measurements on the operational state of high-voltage transformers is considered. Examples of defects of switching devices of converter transformers and methods for their detection are given. The rationale for the importance of recognition of defects at an early stage of their occurrence is given. The influence of the multiplicity of overvoltages on the service life of converter transformers in the aluminum industry is investigated. Based on the analysis of the service life of converter transformers of one of the powerful aluminum plants, where 83% of converter transformers have exhausted their standard service life, it is shown that in 40% of cases it would be possible to avoid their failures, with timely detection and elimination of emerging defects. Examples of defects of OLR (on-load regulators) of converter transformers and methods for their detection are given. The importance of recognition of defects at an early stage of their occurrence is substantiated. A method for chromatographic analysis of dissolved gases in transformer oil has been developed for the qualitative determination of defects and ways to eliminate them. Examples of diagnostics of converter transformers at operating voltage and working load are given, providing the best quality operational characteristics of converter transformers. The periodicity of diagnostic measurements and the reduction of defects and failures has been substantiated. The question of diagnosing the state of the converter transformer TDNP-40000/10 at an enterprise of the aluminum industry is investigated. Currently, diagnostic methods are being developed based on chromatographic analysis of dissolved gases in transformer oil. The presented method of evaluating the operating parameters of transformers allows for the safe operation of high-voltage transformers and enables to increase the reliability of the power supply scheme of aluminum industry plants.

The Aluminum Industry

Carbon-like materials such as the anode and the ramming paste play a crucial role in the efficiency of the Hall–Héroult process. The mechanical behavior of these materials during forming processes is complex and still ill-understood. This work aimed to investigate experimentally the mechanical behavior of a carbon paste used in the aluminum industry under different loading conditions. For this purpose, experiments consisting of (1) relaxation tests at different compaction levels, (2) quasi-static cyclic tests at several amplitudes, (3) monotonic compaction tests at varied strain rates, and (4) vibrocompaction tests at different frequencies were carried out. The obtained results highlight some fundamental aspects of the carbon paste behavior such as the strain rate’s effect on the paste compressibility, the hardening-softening behavior under cyclic loadings, the effect of cycling amplitude on the stress state and the paste densification, and the frequency effect on the vibrocompaction process. These results pave the way for the development of reliable rheological models for the modeling and the numerical simulation of carbon pastes forming processes.

This article critically analyses the opportunities for Australia to revitalise its strategically important manufacturing sector in the wake of the COVID-19 pandemic. It considers Australia’s industry policy options on the basis of both advances in the theory of industrial policy and recent policy proposals in the Australian context. It draws on recent work from The Australia Institute’s Centre for Future Work examining the prospects for Australian manufacturing renewal in a post-COVID-19 economy, together with other recent work in political economy, economic geography and labour process theory critically evaluating the Fourth Industrial Revolution (i4.0) and its implications for the Australian economy. The aim of the article is to contribute to and further develop the debate about the future of government intervention in manufacturing and industry policy in Australia. Crucially, the argument links the future development of Australian manufacturing with a focus on renewable energy. JEL Codes: L50; L52; L78; O10; O13: O25; O44; P18; Q42

IntroductionAdvocacy is vital for advancing tobacco control and there has been considerable investment in this area. While much is known about tobacco industry interference (TII), there is little research on advocates’ efforts in countering TII and what they need to succeed. We sought to examine this and focused on low- and middle-income countries (LMICs) where adoption and implementation of the Framework Convention on Tobacco Control (FCTC) tend to remain slower and weaker.MethodWe interviewed 22 advocates from eight LMICs with recent progress in a tobacco control policy. We explored participants’ experiences in countering TII, including the activities they undertake, challenges they encounter and how their efforts could be enhanced. We used Qualitative Description to analyse transcripts and validated findings through participant feedback.ResultsWe identified four main areas of countering activities: (1) generating and compiling data and evidence, (2) accessing policymakers and restricting industry access, (3) working with media and (4) engaging in a national coalition. Each area was linked to challenges, including (1) lack of data, (2) no/weak implementation of FCTC Article 5.3, (3) industry ties with media professionals and (4) advocates’ limited capacity. To address these challenges, participants suggested initiatives, including access to country-specific data, building advocates’ skills in compiling and using such data in research and monitoring, and in coalition development; others aiming at training journalists to question and investigate TII; and finally, diverse interventions intended to advance a whole-of-government approach to tobacco control. Structural changes to tobacco control funding and coordination were suggested to facilitate the proposed measures.ConclusionThis research highlights that following years of investment in tobacco control in LMICs, there is growing confidence in addressing TII. We identify straightforward initiatives that could strengthen such efforts. This research also underscores that more structural changes to enhance tobacco control capacity building should be considered.
