Ekološka procjena metalurških tvrtki nakon privatizacije i restrukturiranja

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 functioning of all the enterprises, among them also the metallurgical enterprises. On the basis of the metallurgical company Ferrum SA (joint-stock company), the producer of the pipes, the road of the company towards the competitiveness is presented. The bases for the comparisons were various ecological aspects. Data from the environment reports of the metallurgical company Ferrum SA were used in order to conduct the analysis.Cilj rada bio je predstavljanje i provedba ekoloških djelovanja u metalurškoj tvrtki u Poljskoj nakon privatizacije i temeljitog restrukturiranja. Provođenje privatizacije državnih poduzeća proizlazi iz transformacije nacionalne ekonomije. Tržišni sustav uvodi prisilne promjene u funkcioniranje svih poduzeća, među njima i metalurških poduzeća. Na osnovi metalurške tvrtke Ferrum SA (dioničko društvo), proizvođača cijevi, prikazan je put kompanije prema kompetitivnosti. Osnove za usporedbu su različiti ekološki aspekti. Podaci iz ekoloških izvješća metalurške tvrtke Ferrum SA koristili su se za provedbu analize

Procjena aspekata okoliša u metalurškoj industriji

The publication characterises the quantity and quality methods applied in the assessment of the environmental aspects. The method of cumulated environmental loads is particularly interesting, where the network of process connections within an enterprise and between it and the surrounding (the co-operation of the enterprise with the suppliers of resources and materials, the networks of energy resources and distributors of products or other contributors in the chain of added value. The paper finishes with an example presenting the methodological assessment of the environmental aspects in the metallurgical enterprise.Ova publikacija karakterizira kvalitativne i kvantitativne metode primjene u procjeni aspekata okoliša. Metoda ukupnog opterećenja okoliša posebno je zanimljiva tamo gdje postoje povezanosti procesa unutar industrije i povezanosti između industrije i okoliša (suradnja ondustrije s dobavljačima resursa i materijala, povezanost energetskih resursa i distributera produkata ili ostalih suradnika u lancu dodane vrijednosti). Rad završava s primjerom predstavljanja aspekata okoliša u metalurškoj industriji

Primjer modela izgradnje povjerenja u lancima opskrbe poduzeća u metalurgiji

The article is an introduction to the notion of building trust in supply chains. Foreign publishers offer many articles connected with trust and some of the most important ones were quoted in this article. In business world there are models based on trust of the companies which are connected with one another and such models are very popular. Trust becomes the key link in the organisation of supply chains. It is one of the basic mechanisms of action co-ordination which provides the correctness of functioning in the whole chain. The growth of importance of trust between the links of the chain is also observed in metallurgy sector. For the purpose of this publication example models of supply chains structures were constructed in which relationships are based on mutual trust with characteristics of the metallurgical sector taken into account.Članak je uvod u primjer izgradnje povjerenja u opskrbnim lancima. Inostrani nakladnici objavljuju mnoge članke povezane s povjerenjem, a neke od najvažnijih su citirani u ovom članku. U poslovnom svijetu postoje modeli temeljeni na povjerenju tvrtki koje su povezane jedna s drugom i takvi modeli su vrlo popularni. Povjerenje postaje ključna karika u organizaciji opskrbe. To je jedan od temeljnih mehanizama koordinacije koji osigurava ispravnost funkcioniranja unutar cijelog lanca. Rast važnosti povjerenja među tvrtkama unutar lanca opskrbe je također promatrana u sektoru metalurgije. Za potrebe ovog rada kreirani su primjeri modela lanaca opskrbe u kojima se odnosi temelje na međusobnom povjerenju kod čega su uzeta obilježja metalurškog sektora

Mjerenje razine buke internih prometnica proizvodne metalurške tvrtke

This publication shows the results of measurements of the noise level emitted by the motor trucks on the internal roads of the steelworks. The distribution of the metallurgical products with the use of trucks is, next to the rail transport, one of the main logistic forms of products delivery to the customer. The research was conducted on one of the busiest internal roads of metallurgical enterprise ArcelorMittal Poland in Dąbrowa Górnicza. The enterprise conducts the whole production cycle and is the biggest steel producer in Poland. On the premises of the steelworks there were five points of measurements marked where the noise level is measured and the results were compared with the acceptable noise levels defined in the norms.Članak daje rezultate mjerenja razine buke emitirane od motornih vozila internih prometnica čeličane. Distribucija metalurških proizvoda rabeći ova vozila uz željeznički transport je najvažniji način isporuke proizvoda kupcima. Istraživanja su provedena na najprometnijoj internoj prometnici metalurške tvrtke ArcelorMittal Poland u Dąbrowa Górnicza. Poduzeće sadrži sve proizvodne cikluse i najveći je proizvođač čelika u Poljskoj. Unutar prostorija čeličana odabrano je pet točaka gdje je mjerenja razina buke, a rezultati su uspoređivani sa prihvatljivim razinama buke zacrtanim u normama

Kristalizacija i struktura lijevane A 390.0 legure iz taline zagrijane na povišenim temperaturama

The paper presents the research on the influence of melt overheating temperature on crystallization parameters and primary structure of cast AlSi17Cu5Mg (A390.0) alloy overheated to temperature: 820 °C, 880 °C, 940 °C and 1 000 °C. It was found that the degree of overheating influences the change of microstructure significantly and morphologies of primary silicon of the castings from Al-Si alloys. Research has shown that the overheating of the liquid metal bath is one of the methods of finding more applications of hypereutectic Al-Si system alloys without the addition of modifiers.Članak daje istraživanje utjecaja taline na parametre kristalizacije i primarne strukture lijevane legure AlSi17Cu5Mg (A 390.0) zagrijane na povišenim temperaturama: 820 °C, 880 °C, 940 °C i 1 000 °C. Utvrđeno je da stupanj utjecaja pregrijavanja mjenja značajnije mikrostrukturu silikata lijevanih Al-Si legura. Istraživanje ukazuje da pregrijavanje tekućeg metala je jedna od metoda pronalaženja veće primjene hipereutektičkih Al-Si legura bez dodataka modifikatora
