Carbon steel coupons were exposed to nutritionally-poor synthetic wastewater inoculated with activated sludge from a municipal waste water plant. Biofilm formation was observed after one day incubation, and the thickness of the film increased proportionally with the incubation period. Mass loss of the coupons was also proportional to the incubation time, and reached 70.4 (mg/cm2) after incubati...

The behavior of the slag layer between the oscillating mold wall, the slag rim, the slag/liquid steel interface, and the solidifying steel shell, is of immense importance for the surface quality of continuous-cast steel. A computational model of the meniscus region has been developed, that includes transient heat transfer, multi-phase fluid flow, solidification of the slag, and movement of the ...

In nuclear energy systems, the major construction inputs are steel and concrete, which comprise over 95% of the material energy inputs. The evaluation of construction material inputs is central to life-cycle assessments for environmental impacts for nuclear and other non-fossil energy systems, and can provide a useful, if only qualitative, plausibility check for economics claims. This paper com...

environmental degradation and economic growth are two important proofs in sustainable developmentwhich are followed by steel industry. in this case, energy and environmental damages as sustainabilitypatterns of environment have been investigated in three different dust collectors to select the mostenvironmentally suitable dust collector for electric furnace. in this article, the consumption amo...

The corrosion inhibition of ST37 Carbon Steel in 1.0 M HCl by aquatic extract of coconut has been studied as a possible source of green inhibitor using the potentiodynamic polarization and electrochemical impedance spectroscopy techniques. The aquatic extract of coconut have many advantages over classical techniques of sample preparation of plant gums (such as drying and solvent reflux).Pol...

This work further elaborates on the steel plant MILP production scheduling method presented in Harjunkoski and Grossmann (2001). The proposed improvements include a more flexible model for the casting step, as well as combining orders from consecutive weeks to improve one of the main targets, which is increasing the number of heats per casting sequence. The paper presents a strategy to obtain o...

During the last ten years or so, a number of statutory provisions have been enacted with the eventual object of controlling and restricting the amount of pollution which can be permitted or tolerated in the water systems of the European Continent. Against this background the authors examine the iron and steel industry as it exists in France, tabulating the principal processes likely to be encou...
