Energy conservation in the steel industry

The last few years have witnessed an unprecedented increase in the price of energy available to industry in the United Kingdom and worldwide. The steel industry, as a major consumer of energy delivered in U.K. (8% of national total and nearly 25% of industrial total) and whose energy costs currently form some 28% of the total manufacturing cost, is very much aware of the need to conserve energy. Because of the complexities of steelmaking processes it is imperative that a full understanding of each process and its interlinking role in an integrated steelworks is understood. An analysis of energy distribution shows that as much as 70% of heat input is dissipated to the environment in a variety of forms. Of these, waste gases offer the best potential for energy conservation. The study identifies areas for and discusses novel methods of energy conservation in each process. Application of these schemes in BSC works is developed and their economic incentives highlighted. A major part of this thesis describes design, development and testing of a novel ceramic rotary regenerator for heat recovery from high temperature waste gases, where no such system is available. The regenerator is a compact, efficient heat exchanger. Application of such a system to a reheating furnace provides a fuel saving of up to 40%. A mathematical model developed is verified on the pilot plant. The results obtained confirm the success of the concept and material selection and outlines the work needed to develop an industrial unit. Last, but not least, the key position of an energy manager in an energy conservation programme is identified and a new Energy Management Model for the BSC is developed.

La siderurgia malagueña (1899-1924)

Basado en una documentación inédita de archivos de París, Roubaix y Antequera, este artículo estudia un tema prácticamente virgen: la historia de la antigua fábrica de Heredia entre 1899, año en el que fue vendida a Hauts Fourneaux, Forges et Aciéries de Málaga, y 1924, fecha en la que cerró Altos Hornos de Andalucía, su sucesora. Tras sintetizar la historia de ambas empresas, el trabajo analiza las causas que explican el fracaso del intento de resucitar la siderurgia malagueña.

Las ayudas estatales para la reestructuración de la siderurgia española en perspectiva europea (1975-1988)

El objetivo de este artículo es realizar una comparación cuantitativa de las ayudas públicas destinadas a los procesos de reestructuración de la siderurgia en España y en los países de la CECA en el período 1975-1988. Las fuentes utilizadas corresponden tanto a documentación de archivo como a publicaciones periódicas de diversas instituciones: empresas españolas, patronal siderúrgica (Unesid), organismos públicos españoles y de la CEE e informes de la Comisión Europea. El trabajo demuestra que la principal diferencia entre la políticas siderúrgicas española y comunitaria estribó no tanto en el montante de las ayudas públicas destinadas al proceso de reestructuración como en el uso que se hizo de las mismas. Así, mientras en la CEE las ayudas públicas estuvieron condicionadas a la eliminación de los excedentes de capacidad productiva, en España no se realizó ningún ajuste en este sentido hasta nuestra integración en la Comunidad en 1986.

Mapping the global flow of steel: from steelmaking to end-use goods.

Our society is addicted to steel. Global demand for steel has risen to 1.4 billion tonnes a year and is set to at least double by 2050, while the steel industry generates nearly a 10th of the world's energy related CO₂ emissions. Meeting our 2050 climate change targets would require a 75% reduction in CO₂ emissions for every tonne of steel produced and finding credible solutions is proving a challenge. The starting point for understanding the environmental impacts of steel production is to accurately map the global steel supply chain and identify the biggest steel flows where actions can be directed to deliver the largest impact. In this paper we present a map of global steel, which for the first time traces steel flows from steelmaking, through casting, forming, and rolling, to the fabrication of final goods. The diagram reveals the relative scale of steel flows and shows where efforts to improve energy and material efficiency should be focused.

Transitions to material efficiency in the UK steel economy.

Steel production is energy intensive so already has achieved impressive levels of energy efficiency. If the emissions associated with steel must be reduced in line with the requirements of the UK Climate Change Act, demand for new steel must be reduced. The strategies of 'material efficiency' aim to achieve such a reduction, while delivering the same final services. To meet the emissions targets set into UK law, UK consumption of steel must be reduced to 30 per cent of present levels by 2050. Previous work has revealed six strategies that could contribute to this target, and this paper presents an approximate analysis of the required transition. A macro-economic analysis of steel in the UK shows that while the steel industry is relatively small, the construction and manufacturing sectors are large, and it would be politically unacceptable to pursue options that lead to a major contraction in other sectors. Alternative business models are therefore required, and these are explored through four representative products--one for each final sector with particular emphasis given to options for reducing product weight, and extending product life. Preliminary evidence on the triggers that would lead to customers preferring these options is presented and organized in order to predict required policy measures. The estimated analysis of transitions explored in this paper is used to define target questions for future research in the area.

The steel scrap age.

Steel production accounts for 25% of industrial carbon emissions. Long-term forecasts of steel demand and scrap supply are needed to develop strategies for how the steel industry could respond to industrialization and urbanization in the developing world while simultaneously reducing its environmental impact, and in particular, its carbon footprint. We developed a dynamic stock model to estimate future final demand for steel and the available scrap for 10 world regions. Based on evidence from developed countries, we assumed that per capita in-use stocks will saturate eventually. We determined the response of the entire steel cycle to stock saturation, in particular the future split between primary and secondary steel production. During the 21st century, steel demand may peak in the developed world, China, the Middle East, Latin America, and India. As China completes its industrialization, global primary steel production may peak between 2020 and 2030 and decline thereafter. We developed a capacity model to show how extensive trade of finished steel could prolong the lifetime of the Chinese steelmaking assets. Secondary steel production will more than double by 2050, and it may surpass primary production between 2050 and 2060: the late 21st century can become the steel scrap age.

The incentives for supply chain collaboration to improve material efficiency in the use of steel: An analysis using input output techniques

In the face of increasing demand and limited emission reduction opportunities, the steel industry will have to look beyond its process emissions to bear its share of emission reduction targets. One option is to improve material efficiency - reducing the amount of metal required to meet services. In this context, the purpose of this paper is to explore why opportunities to improve material efficiency through upstream measures such as yield improvement and lightweighting might remain underexploited by industry. Established input-output techniques are applied to the GTAP 7 multi-regional input-output model to quantify the incentives for companies in key steel-using sectors (such as property developers and automotive companies) to seek opportunities to improve material efficiency in their upstream supply chains under different short-run carbon price scenarios. Because of the underlying assumptions, the incentives are interpreted as overestimates. The principal result of the paper is that these generous estimates of the incentives for material efficiency caused by a carbon price are offset by the disincentives to material efficiency caused by labour taxes. Reliance on a carbon price alone to deliver material efficiency would therefore be misguided and additional policy interventions to support material efficiency should be considered. © 2013 Elsevier B.V.

No tan diferentes. La actividad empresarial de los siderúrgicos españoles en el contexto europeo (1891-1936)

A la hora de explicar las causas del atraso relativo de España en las décadas previas a la Guerra Civil, algunos autores han considerado como un factor clave la mayor propensión de los empresarios españoles a las estrategias de búsqueda de rentas, lo que dio lugar a un sector industrial protegido, cartelizado e ineficiente. Dado que la siderurgia es señalada frecuentemente como el paradigma de las funciones improductivas de los empresarios españoles, el presente trabajo pretende, en primer lugar, contrastar las actitudes de los siderúrgicos españoles con las de los franceses y alemanes en las décadas que precedieron a la Primera Guerra Mundial. En segundo lugar, se analizará si la cartelización del mercado entre 1897 y 1936 tuvo consecuencias negativas para el desarrollo económico de España, tales como restricción a la entrada de competidores, ausencia de innovaciones tecnológicas y, como resultado de ello, una oferta rígida para su producción.
