production of thin steel strips with 0.18-0.26 mm thickness is about 0.75 of annual production of the two stand reversing cold mill, while its efficiency is 60%. this is due to the fact that after montaging the grinded work rolls, rolling thin steel strips (with thicknesses less than 0.18 millimeters) is unavailable. initially, unsuitable surface roughness, the friction between rolls and the st...

steel production in iran has been recorded since fourteen century b.c. however the main growth and development in steel industry has occurred in recent decades. steel industry has important role in development of industrial countries, and also steel consumption may consider as an important ind ices in the development process. this pap er has analyzed two main complexes (zobe ahan and mobarakch)...

BACKGROUND Exposure to polycyclic aromatic hydrocarbons (PAHs) has been reported in several industries, including those of the aluminum production, coal gasification, coke production, iron and steel foundries, coal tar and related products, carbon black and carbon electrodes production. PATIENTS AND METHODS This paper reviews the results from cohort studies conducted on workers exposed to PAH...

G. Bălan, Romanian-German University of Sibiu, M.D. Ungureanu, Spiru Haret University of Bucharest, G. Dobrotă, University Constantin Brâncuși of Târgu Jiu, România The objective of this paper is to highlight the current state of the steel industry at the global and regional level, in terms of its level of important indicators, such as: production capacity, production volume, level of consumpti...

Great efforts have been recently made in the world of metallurgy in order to reduce raw material consumption and particularly energy consumption. Although most metallurgical products are produced by the proved procedures of plastic forming, some changes appear owing to the following requirements: – improvement of product quality, – reduction of production costs, – increase of productivity as we...

Cost reduction and high efficiency are the mayor challenges for sustainable H2 production via proton exchange membrane (PEM) electrolysis. Titanium-based components such as bipolar plates (BPP) have the largest contribution to the capital cost. This work proposes the use of stainless steel BPPs coated with Nb and Ti by magnetron sputtering physical vapor deposition (PVD) and vacuum plasma spray...

The energy used to produce austenitic stainless steel was quantified throughout its entire life cycle for three scenarios: (1) current global operations, (2) 100% recycling, and (3) use of only virgin materials. Data are representative of global average operations in the early 2000s. The primary energy requirements to produce 1 metric ton of austenitic stainless steel (with assumed metals conce...

This paper is focused on the tactical design of steel supply chain (SSC). A general mathematical model is proposed to integrate production and transportation planning in multi-commodity SSC. The main purpose is to prepare a countrywide production and distribution plan in an SSC with three layers consisting of iron ore mines as suppliers, steel companies as producers, and subsidiary steel compan...
