The Dep. of Metallurgy in Sisak of the Faculty of Technology Zagreb was founded in 1960 with Ironwork Sisak, Petrol rafinery Sisak and Assembly of the Municipality Sisak as Founders. During 60y (1960-2020) were several organizations transforms, important 1977-1978 y when is Metallurgical Dep./Engineering including in Institutza metalurgiju Sisak, name Metallurgical Faculty. With transform 1990-1991 y Metallurgical Faculty have separate from Institutza metalurgiju Sisak and come into existence as autonomous the organization at University of Zagreb. Till now, have publish many works about history, activities in teaching, scientific and professional works and achievements. In this work published several works of different authors, with original texts from founded 1960 till now 2021. [ABSTRACT FROM AUTHOR]

Sixty years have passed since the foundation and the first publishing of the Metalurgija Journal with Scientifi c, as well as Professional Papers and Contributions from the area of basic, applicable and developing researching in Metallurgy and boundary metallurgy areas. The goal of the Article in Croatian and English language is give whole the description history, organizations of Journal activities and achiewements of Journal from 1962 since 2022 y, with this including List of Boards and Coworkers, were publishing total papers 3 008 ie. 2 721 Scientific and Technical and 287 Contributions, total 3 575 Authors and Co-authors from over 40 Countries. On the occasion of this Anniversary, separately with thanks for Privates, Institutions etc. for dedicated eff ort have managed to overcome many technical, organizational and financial problems encountered over past Years.

This work deals with the development of metalurgy in the world whose beginnings date 7 000 years B.C. On the teritory of today s Croatia metalurgy has been present for 6000 years. Three civilizations have left evidence the Celtic, the Roman and civilization of Vučedol. After the arrival of the Cratis to this teritory, metalurgy developed more intensively in the region of Sisak and Banovina as well as Samobor and Gorski Kotar. Bells and guns were cast in Dubravnik and Zagreb. The industrial production starte din 1853 (Foundry in Rijeka), production of ferroalloys, Šibenik 1900 y, also Dugi Rat 1906 y, and in 1937 the production of aluminium and Al – alloys in Lozovac (continuo by 1905) as with the construction of the blast furnace in Caprag in 1939. In the period after 1945 until 1990, Croatia had several metallurgical companies and acceptable production coke, iron, steel, fero-alloys, electrodes, casting, reinforced concrete steel, seamless and welded tubes, strips, billets, aluminium etc. Total production in Croatia in 1990 was ~ 3 000 000 tons of various metallurgical products (without castings). Per year in 1990 until 2012 plants of over 2 600 000 t of metallurgical per year were torn down or put out of operations. Total metallurgical production in Croatia in was 2011 y 248 910 tons i.e. level 8,3 % (comparison with the production in 1990 y), what is significant of the destruction of Croatia metallurgy for 22 years. The Article give also several press notices to the public information by members of the Croatian Metallurgicall Society and Apprentices in order to sustain and revitalize of the Croatian metalurgy (supplements).

The goal of this article is to give an overview of the foundation and development of Croatian Metallurgical Society (CMS) from the Society of Engineers and Technicians of Steelworks Sisak 1952 – 2012 With monitoring of goals and tasks of CMS, the main activities of the Society are also set out: publishing of the magazine Metalurgija, international symposium „Materials and Metallurgy“, and productive cooperation with an array of institutions in Croatia and abroad but also difficulties in the activities (over 70 institutions from 50th countries). The overview includes also several futile press notices to the public made by the member of the Society of their own initiative, in order to sustain and revitalize the Croatian metallurgy. The Society and the Journal survives on the base of modest financial support by the Ministry of Science and Education and Sport (in 2020 y only for Metalurgija Journal 10 000 EUR and cca 3 000 EUR for activities of Society), of Participation Fees from Symposium and exclusively to volontary work all in Society, without any permanent empoloyees.

The paper considers complex intensification features of spheroidizing annealing of low-carbon steels and possible technological realizations of intensive annealing modes in current lines. The research aims to reveal the intensification nature of the steel’s spheroidizing due to the non-isothermal holding and an internal coolant for the metal heating. That allows a significant reduction of the spheroidizing annealing process while improving the steel product’s technological properties – providing a high dispersion and homogeneity of the structure across the entire plane of its section. The multiprocessor computing system with its mathematical and IT software for modeling the heat treatment modes of metal billets effectively controls the processes. [ABSTRACT FROM AUTHOR]

The beginnings of the world metallurgy date back to the 7000 years B.C. On the territory of today's Croatia, metallurgy has been present for 6000 years. Three civilizations have left the evidence of this: Vucedol, Celtic, and Roman civilization. After the arrival of the Croats, metallurgy has been more intensively present in the Sisak-Banovina and Samobor regions, as well as Gorski Kotar region. Casting of bells (and cannons) was developed in Dubrovnik and Zagreb. The industrial production start date was in 1853 (Foundry in Rijeka), in 1937 (the production of aluminium and Al-alloys in Lozovac) as well as in 1939 with the construction of the blast furnace in Caprag. In the period after 1945, until 1990, Croatia had several metallurgical companies and acceptable production of coke, iron, steel, ferroalloys, electrodes, casting, reinforced concrete steel, seamless and welded tubes, strips, billets, aluminium, etc. In 1990, total production of various metallurgical products in Croatia was 2.670.000 tons of which up to 2.000.000 t/y came from Steelworks Sisak. From 1990 to 2012, over 2.600,00 t/g of metallurgical products were demolished or discontinued, which represented the collapse of Croatian metallurgy. The paper cites more important publications on the Steelworks Sisak, which was a long-standing carrier of metallurgical production in Croatia. There is also a review of the last published Proceedings of the Sisak Ironworks (2019). [ABSTRACT FROM AUTHOR]

The goal of this the Article is to give an overview of the foundation, development and achievements of Croatian Metallurgical Society (CMS) from Society of Engineers and Technicians of Steelwork Sisak (SETSS) 1952 - 2017 (65 years) With monitoring of goals and tasks of CMS, the main activities of the Society are also set out: First, history of the metallurgy on the teritory of today Croatia in the therm 6.000 y till today, with many Articles, Studies etc. In this way, Croatia was ranged between Countries where metallurgy as important technical bransh, has a written document on this history. Second, publishing of the Metalurgija Journal, International Symposiums „Materials and Metallurgy" (was 12 with 5.013 Lectures), and productive cooperation with an array Institutions in Croatia and abroad(over 70).
