SER Jet-Emulsion Process is a new, compact, energy efficient, environmentally friendly and waste-free iron and steel technology. Its physicochemical fundamentals based on the theory of self-organization at significant deviation from thermodynamic equilibrium as well as its industrial features and advantages have been described in our previous publications. In this paper, a mathematical model of one of the main units of this process, the refining column or the gravitational separator is described. The model is based on the 'first principles' Monte Carlo method, in which the particles of charge materials and reaction products interact. The model simulates elastic and inelastic interactions, as well as the chemical transformations that take place in this process. The mathematical model was extensively tested especially in the separation of the constituents of fine-dispersed dust from manganese production. The obtained regularities, reflecting the process dynamics in space and time were proven important for the choice of design and regime parameters of the column reactors.

Paper Id: 192 [Abstract]

In a previous paper, the ORIEN Technology was introduced as a new, compact, energy intensive and self-sufficient as well as environmentally friendly iron and steel technology that has numerous advantages compared to the classical iron and steel production technologies. The purpose of this paper is to describe the basic physicochemical principles of this process. The core of the technology, that can otherwise be named a direct iron-ore to steel technology, is a special direct liquid-state reduction of unique iron-ore cold-pressed briquettes in a single electric furnace unit achieving simultaneously the reduction of iron ore in the briquettes and converting it into steel based on the principles of the energy self-sufficiency. The output of ORIEN process is a unique iron melt of a special type in which the carbon exists in non-equilibrium colloidal form and can be controlled to vary widely from 0.04% to 30%. Based on these fundamentals the new ORIEN technology can be used to produce various degrees of iron melts with different carbon contents in a single electric furnace unit and to replace the classical heavy flowsheet of agglomeration/sinter/pelletizing, coke batteries, blast furnace and BOF convertors. This opens the road for a paradigm shift for fundamental environmental protection, saving energy, decreasing cost and increasing the quality of the steel.

Paper Id: 47 [Abstract]

The impact of two different types of refractory materials and layout in the life cycle of an electro-reduction Fe-Ni arc furnace, during regular production periods, with two different refractory lining materials, are described. It is shown the refractory lining consisting of a combination of magnesite bricks in vertical walls and graphite blocks in the slag levels has a life cycle about 3 times higher compared to the case when all walls were lined with magnesite bricks only. It was also found that although graphite blocks are very resistant to the molten slag, they are vulnerable to molten Fe-Ni alloy, which dilute carbon in it from graphite blocks. In order to avoid this, a modification has been proposed for the layout of the combined refractory lining that prevents the contact of graphite blocks with molten Fe-Ni when raising bath levels of molten metal inside the furnace occur, thus prohibiting carbon from dissolving into the molten alloy. This modification further increases the life cycle of the furnace refractory. This work is part of a long-term project undertaken in cooperation with FLOGEN Technologies Inc. In a subsequent future article, an overall physical simulation of all the above-mentioned phenomena will be presented.

Paper Id: 360 [Abstract]

FLOGEN CONTOP offline and online control expert system was commissioned in Paranapanema smelter in Dias D'Avila to compare different scenarios and support for the optimization of the Hoboken Converters operation. The software results indicate the possibility to decrease the amount of silica used as a flux, minimize the slag and copper blowing time, maximize the use of reverts, minimize slag volume, and decrease copper losses in the slag. The main process parameters (such as bath temperature, Sulphur content in Blister and Copper in the slag) is calculated during the operation, providing a clearer overview of the process and supporting to determine the end of blowing based on technical evaluation. This presentation will describe some of these achievements.

The technogenic copper deposit 'Depo slag l " is located in the industrial smelter and refining copper company RTB Bor. Mineable reserves amounted to 9,190,940 t of slag with an average copper content of 0.715%. A sample of this “Depo I” is melted in the furnace and then in the course of discharging in a thin stream a jet of water cooled wherefrom the small - granular pieces. The characteristics of raw and remelted slag were compared. The paper presents: chemical analysis, SEM - EDS analysis, Bond's work index in the mill with balls and bars, kinetics experiments of grinding and flotation of copper bearing particles, depending on the fineness in the range of 60 - 95% -0,075 mm.

Ferronickel slags, due to their physicochemical characteristics, have good potential to improve the performance of construction materials when properly and adequately used as a component in these materials. As such, instead of being a waste that harms the environment, they can be turned into valuable materials for the construction industry assuring an efficient use of resources. As part of a bigger cooperation project with FLOGEN Technologies Inc. this paper gives the results of an investigation on the use of ferronickel slags from Ferronickel Company in Kosovo in several construction materials such as cement, asphalt, concrete, etc. The goal of the project is to determine the best recipes for the optimal use of the ferronickel slags in the construction materials in order to achieve their best physico-mechanical properties. Based on numerous laboratory analysis various mixture ratios of slag in the construction products have been studied followed by laboratory examination of the physical-mechanical properties of the corresponding mixtures. It was found that the use of ferronickel slag from Ferronickel Company can be beneficial to improve the mechanical and physical properties of all construction materials and at the same time protect the environment by turning a waste of metallurgical industry in a useful primary material for the construction industry.

The scope of applications of silicon nitride (Si3N4) has increased notably in the last years. In addition to its well-known structural properties, not only it has been considered as matrix or reinforcement in metal and ceramic composites but also as electronic material and biomaterial. Owing to the variety of phase shapes in which it can be produced, namely, particles, whiskers, fibers, films and coatings, Si3N4 is selected for various applications. Recently, orthopedic applications and bacteriostatic characteristics of silicon nitride compared to that of titanium biomaterials have been reported. Inherent to the potential of Si3N4 is the synthesis route used. The hybrid system chemical vapor deposition (or infiltration) (HYSY-CVD, HYSY-CVI) route has been proposed and applied for synthesizing Si3N4 in a variety of morphologies. Alpha silicon nitride produced by this route has also been reported as a promising candidate for emitting in the blue light region. In this contribution, authors present a review on the most recent applications of Si3N4, including structural and functional applications, as electronic material and as bioceramic or biomaterial.
