B. Gajdzik, The Silesian University of Technology, Faculty of Materials Science and Metallurgy, Katowice, Poland J. Sitko, The Silesian University of Technology, Faculty of Organization and Management, Zabrze, Poland The publication presents the causes of complaints about metallurgical products, illustrated with an example of steel sheets, with a particular focus on the reasons having their sou...

Ferrous metallurgy enterprises continuously fill dumps with steelmaking and blast furnace sludge high zinc content. Sludge occupying significant territories of is not involved in production harms the environment. Since leads to formation deposits furnace, manufacturers cannot involve this sinter processing. In addition, working can lead problems such as decrease iron content sinter, productivit...

The aim of the article was the presentation of the ecological eff ects achieved in the metallurgical company in Poland after privatization and overall, thorough restructuring. For the need to conduct privatization of the state-owned enterprises and their restricting resulted from the transformation of the national economy. The market system forced the introduction of the changes in the function...

We present absolute geomagnetic intensities from iron smelting furnaces discovered at the metallurgical site of Korsimoro, Burkina Faso. Up to now, archaeologists recognized four different types of furnaces based on different construction methods, which were related to four subsequent time periods. Additionally, radiocarbon ages obtained from charcoal confine the studied furnaces to ages rangin...

Autoregressive models with exogenous inputs are useful tools for analyzing systems with unknown dynamics, but are limited by the assumption that the relations between inputs and output(s) are linear. For complex systems with nonlinear or abruptly changing dynamics it is possible to modify the technique by allowing for multiple local models and designing a strategy for switching between them. A ...

OBJECTIVES To determine blood-lead (Pb) levels in pregnant women and neonates in a metallurgical city of Peru. MATERIALS AND METHODS A cross-sectional study was carried out, the population of which consisted of pregnant women who had lived for at least two years in the city of La Oroya, at the time when the lead, copper and zinc foundries operated normally. A blood sample was obtained from th...

A mathematical heat transfer model for the prediction of transient heating of the slab in a direct-fired walking beam type reheating furnace has been developed by considering the nongray thermal radiation with given furnace environments. The furnace is modeled as radiating nongray medium with carbon dioxide and water with five-zoned gas temperature and the furnace wall is considered as a consta...

Abstract The Boudouard reactivity of metallurgical coke and densified charcoals was investigated in this study. Potassium is known to accumulate ferromanganese furnaces hence evaluated as a catalyst CO 2 reactivity. Samples were impregnated using gaseous impregnation technique with K 3 .The experiments designed simulate conditions occurring an industrial furnace, used for production Mn-alloys. ...
