The specification of documentation for anti-dumping investigation in metallurgy using ABC costing method

In today’s globalized market economy, business companies are active both in domestic and in foreign markets, thus increasing the importance of observing the international rules providing guidelines for mutual trade among countries within the global trading system. Metallurgical materials and products are among the products in case of which anti-dumping duty is often imposed. As far as the decisions on possible dumping and its amount are concerned, the market with metallurgical products and the methodology used for calculating the dumping range have certain specific features, as stated in the article

The application of winning key metrics in a metallurgical firm

This article is focused on creating a system of metrics and its application in a metallurgical firm. Its aim is to highlight the dangers associated with the creation and application of an effective system of metrics. Its objective is also to demonstrate the process (initial steps) in the development of this system in the real family metallurgical firm. In the experimental part an example of causal links among key metrics in the chosen metallurgical firm is presented. Risks associated with the selection of appropriate metrics are presented for discussion

Alkaline carbonates in blast furnace process

The production of iron in blast furnaces is a complex of physical, chemical and mechanical processes. The input raw materials contain not only metallic components, but also a number of negative elements. The most important negative elements include alkaline carbonates. They can significantly affect the course of the blast furnace process and thus the overall performance of the furnace. As a result of that, it is essential to accurately monitor the alkali content in the blast furnace raw materials. The article analyzes the alkali content in input and output raw materials and their impact on the blast furnace process

Analysis of ecological intensity of metallurgical production

Ferrous metallurgy is inherently a highly intensive field in terms of energy and raw materials. The impacts of high energy intensity are enormous: the necessary production of larger amount of energy related to high emissions of pollutants and greenhouse gases, associated with increasing negative impacts on the state of the environment and the health of inhabitants. The article suggests the possibility of using the method of structural analysis to calculate direct and complex ecological intensity and to use it as a basis to determine the ecological intensity of the individual metallurgical technologies. The processing of ecological structural model can significantly contribute to the identification of ecologically intensive final products and can improve the decision-making process in this area

Evaluation of benefits resulting from innovation of input raw materials dosing process in sintering

Production of blast furnace sinter is among the processes with the highest energy and material requirements. Fuel consumption is especially significant cost item here. The presence of grate sintered in charge, i.e. return sinter from 12 to 22 mm in size, can have fundamental impact on the technical and economic indicators of the sintering process. Grate sinter can be used as a foundation layer under the sintering mixture, to increase air permeability of charge and to improve the gas-dynamic conditions. The article analyzes the impact of grate sinter on the sintering process, based on an analysis of the acquired production indicators within the scope of the research in question

Analysis of energy demandingness of metallurgical production

The article suggests the possibility of using methods of structural analysis to calculate the direct and complex consumption and, on the basis of this calculation, are can determine the energy demandingness of the individual metallurgical technologies

Polynomials over quaternions and coquaternions: a unified approach

This paper aims to present, in a unified manner, results which are valid on both the algebras of quaternions and coquaternions and, simultaneously, call the attention to the main differences between these two algebras. The rings of one-sided polynomials over each of these algebras are studied and some important differences in what concerns the structure of the set of their zeros are remarked. Examples illustrating this different behavior of the zero-sets of quaternionic and coquaternionic polynomials are also presented.(undefined)info:eu-repo/semantics/publishedVersio
