The paper considers the historical development of scientific views on structure oxide and metal melts. authors, using research Ural Scientific School their own works as examples, examine evolution approaches based polymer (ionic) theory melts cluster liquid metals. possibility a model to determine boundary slag transition from homogeneous state heterogeneous one conditions for formation with maximum refining properties is shown. Al 2 O 3 can exhibit both basic acidic properties. It was found...
The processes of iron oxides’ reduction have a complex physicochemical mechanism, with the participation solid, liquid, and gaseous substances. article discusses existing models for oxides provides data on thermodynamic possibility carrying out reactions their through solid gas phases. Experimental from industrial scale, obtained by DSC (differential scanning calorimetry) method, show kinetic dependence rate completeness recovery external factors: pressing pressure during sample preparation...
A range of process solutions in the field industrial waste recycling was reviewed. technology suggested for red muds disposal aluminium industry by their introduction into iron-ore agglomerates and pellets. The comprehensive waste-free considered with use rotary ore thermal furnaces obtaining cast iron (ferrosilicon) alumocalcite slag cement production. variant joint two wastes greasy rolling mill scale. Efficiency environmentally safe vanadium-containing converter slags processing ensuring...
The work presents the study and development of joint processing ladle furnace electric arc slag with no waste left. experimental results proved that could be utilized jointly. revealed chemical compositions slag, which allow effective utilization. products this utilization are cast iron Portland clinker without any residue Final meet requirements normative documents. also operations for processing.
The approach to solving the problem of processing iron ore raw materials Tebinbulak titanomagnetite deposit (Uzbekistan) is offered. It can provide high-quality steel products. two schemes are shown. choice between proposed processing: variant "blast furnace – converter" and "metallization electric smelting" should be made after thorough analysis based on many factors.
The article gives analysis of long-term and perspective tasks automating EAF, particularly relevant to the conditions domestic production. results studies on quality control foaming slag in super-power EAF-135 OJSC "Seversky Pipe Plant" are shown. We made conclusions about possibilities using electrical mode parameters for operational processes smelting steel ferroalloys.
An approach to managing the main modes of smelting steel in heavy-duty electric arc furnaces (EAF) using digital twin technology was defined and formulated. It noted, that existing power regulators do not have function balancing effective phases and, accordingly, arcs because they are focused on working with a certain average value signal. is proposed use analysis dynamic characteristics based instantaneous values input parameters instead operating ones, as it’s usually implemented most...
The study considers ways to increase the efficiency of reduction iron oxides from man-made waste (dust electric arc furnaces) using mechanochemical activation (MCA), grinding and pressing. analysis chemical phase compositions dust samples was carried out, which made it possible identify their potential for processing. experiments included a effect pressing at pressures up 300 MPa on materials’ composition, as well an assessment effects coke addition during MCA. To pressure processes,...
Abstract The technological features of processes for the production steelmaking slags use in building materials and products are presented, improvement properties refining slag stabilization via introduction alumina flux demonstrated. mechanism by is also discussed. In addition, preparation Portland cement clinker with a high content iron oxides from controlled phase composition described.
