The results of the study of structures and mechanical properties of ceramic materials will be discussed. These ceramic materials were obtained by hot pressing from the submicron AlB₁₂C₂ and AlB₁₂ powder [1], with and without the addition of TiC, as well as from B₄C, without and with SiC additions. Temperature, pressure and composition of the starting powder are optimized to obtain sintered bodies with desired high mechanical characteristics. X-ray diffraction, scanning electron microscopy and Raman microspectroscopy are utilized to investigate phase composition and microstructure of the sintered ceramics. High compression strength (1551 MPa for B₄C, 1878 MPa for B₄C-SiC-based material and 795 MPa for AlB₁₂C₂-TiB₂ based material) together with high bending strength, hardness, fracture toughness, and a light weight make the synthesized and sintered ceramics very promising as a shock-wave resistant material. The effect of C, TiC and SiC additions on the properties of the resultant composites and the particularities of the ceramics destruction under shock loading will be discussed. The results of the modeling of ballistic characteristics will be discussed. The performed ballistic tests of 10 mm thick plates from the developed ceramic had a 2.63 g/cm³ density as well as a composition of 78 wt.% of B₄C and 22 wt.% of SiC according to X-ray diffraction analysis. According to SEM microprobe X-ray analysis, stoichiometries B_3.64CSi_0.01 and SiC_1.07, respectively, showed that the plates can withstand the shot of a B32 bullet with kinetic energy of 3.7 kJ from a 10 m distance.

Paper Id: 483 [Abstract]

FLOGEN Decision Making, Control, and Optimization system has been applied in Waltz Rotary Kiln that produces Zn from steel dust. This resulted in simultaneously reducing the specific coke/coal consumption, maximizing Zn yield, decreasing Zn losses in the slag, minimizing accretions and balls inside the furnace, increasing the operational time without stoppages and enabled greater flexibility in using multiple raw materials. This paper presents some of the above results along with the most recent developments of application in other processes

Rotary Kiln Dust As A Raw Material For Production Of The Magnesium Sulphate In MIM - GOLESHI
Shefik Imeri¹ ; Florian Kongoli² ; ¹MIM-GOLESH, Prishtina, Kosovo; ²FLOGEN Technologies Inc., Mont-Royal, Canada;
Paper Id: 167 [Abstract]

The rotary kiln process that produces magnesite sinter creates a considerable amount of dust that contains up to 96% MgO [1]. Usually the quantity of the produced dust is 16% of the quantity of the magnesite concentrate charged in the Rotary Kiln. Up to now, about 90% of the dust is recycled with the feed of the Rotary Kiln, while about 10% of this quantity is lost with the gas. The quantity of the dust recycled creates various problems in the Rotary Kiln such as process disturbances, creation of accretions that decrease the active volume, and decreases in the productivity of magnesite sinter. Another alternative is to stop dust recycling in the Rotary Kiln and use it as a raw material to produce magnesium sulphate in a separate unit after the dedusting chamber. Eliminating dust recycling in the Rotary Kiln will improve the stability and efficiency of the process, increase the production rate since new magnesite concentrate will be charged in the feed instead of the dust, and significantly decrease the production cost of the magnesite sinter. The magnesium sulphate produced in this way will also constitute a new marketable product that will increase the profit of the company. In this paper, the production of magnesium sulphate using the magnesite sinter Rotary Kiln dust as a raw material will be studied and evaluated and the best production technology will be suggested while, in a subsequent publication, a description of the project on building and commissioning of magnesium sulphate production unit and its process will be described.

Self-organizing jet emulsion reactor (SER), during generation of which some principles of theory of self-organization and a number of interesting physical effects were used, is of certain degree of universality. Pilot installation has demonstrated possibility of implementing several low-energy and even waste-free technologies on it, including: direct reduction of dust-type ores and waste without agglomeration, production of manganese alloys from poor dust-type concentrates, waste-free separation of titanium-magnetite concentrates into metal and conditioned titanium slag, etc. Presented report focuses on technology of direct reduction of manganese in JESI from dust-type ores and concentrates, including oxidized and carbonate ones. Specifics of technology is generation of full cycle of combustion products recycling, which allow for preliminary recovery or roasting of manganese ores in fluosolid unit connected to the output of the main unit, and reduction of energy costs for production of manganese alloys.

Paper Id: 485 [Abstract]

The main method of production of the most common ferroalloys such as ferromanganese, ferrosilicon, ferrochromium is the electric furnace. The energy of this furnace is based on the combined use of electrical energy to create the necessary heat that is released in the area of ​​the electrodes as well as in the charge when an electric current passes through it. The advantages and disadvantages of this method of supplying energy are well known. One of the disadvantages is increased energy consumption and reduced productivity. ORIEN Technology is a new method for producing of ferroalloys, which differs from the existing methods of using electric arc heating as a heat source, which is typical for electric arc steel furnaces operating with high electric voltage. The most characteristic feature of this innovative solution is the combination of raw material supply and carbothermic reductions by preliminary agglomeration ore (as raw materials) with carbon (as a reducing agent) and continuous supply of agglomerated materials into the combustion zone of the electric arc. This method is a further development of steel production technology - that bear the same name: ORIEN process. This new technology reduces energy consumption, increases productivity, expands the range of ferroalloys and improves their quality. This process can use natural ore as raw materials as well as poor ores with low content of alloy elements.

FLOGEN Technologies Inc. has implemented and commissioned FLOGEN CONTOP, a Design/Decision-Making/Control/Optimization/Automation System at various blast furnaces of pig iron producers in Brazil. The system instantaneously makes a complete optimization of all raw materials, including limestone, silica, air and oxygen volumes, in order to achieve specific targets according to the needs of the company. The main achievements of the implementation of the FLOGEN CONTOP system were the increase of the pig iron production by about 14% and the decrease of total consumption of charcoal (breeze and fines) by about 4%. Additionally, fines injected through the tuyeres were decreased, temperature and composition of slag and pig iron (including Si and P) were better controlled and silica addition as a flux was minimized. An overall instantaneous mass and energy balance helped fix various mechanical and procedural problems in the plant. CONTOP system was also successfully used to determine the annual procurement strategies by predicting various raw material cost-based scenarios related to productivity and fuel consumption in short- and long-term future. CONTOP increased productivity and reduced cost up to the highest designed limit of the technology. CONTOP also changed the way of operating from a reactive wait-the-lab-results-approach to a proactive forecast-and-act approach.
