    Temperature field in the setting of mullite corundum products in a tunnel kiln (1981)
    Springer
    Refractories and industrial ceramics 22 (1981), S. 253-258 
    Details
    ISSN: 1573-9139
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Conclusions Investigations of the temperature field of the setting in a tunnel kiln of the high-alumina products section of the Zaporozhe Refractories Factory revealed individual features of the firing cycle for mullite-corundum articles; the low temperature of the setting in the first heated positions of the firing zone (Nos. 24–26) working without automatic regulation of the gas consumption according to the prescribed temperature of the kiln; the irregularity of the temperature field over the height and width of the setting; the variability of the linear dimensions and quality factors of the finished goods over the setting volume. Certain measures were worked out and used to eliminate these drawbacks. We obtained the general relationship for developing temperature fields in settings in actual kilns present in the department making aluminous, fireclay, and magnesia goods: when ensuring that tkiln=const in the “leading” positions for burning the fuel in the firing zone we noted the extreme behavior of the temperature at the surfaces of the heated goods with a maximum at one or two positions. On the basis of the analysis of the processes of heat and body exchange occurring in the tunnel kiln, we note methods for improving its heat work and also the quality of the goods.

    Some questions of the dynamics of pressing on a P-907 hydraulic press (1983)
    Springer
    Refractories and industrial ceramics 24 (1983), S. 635-639 
    Details
    ISSN: 1573-9139
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Conclusions A method is proposed for investigating certain questions of the dynamics of pressing on a P-907 hydraulic press which makes it possible to reveal the rules of occurrence of the process with time and to determine the optimum operating parameters for different mixtures in adjustment and preventive maintenance of the press. An analysis of operation of the P-907 press indicates the necessity of continuous recording of its energy parameters, the full pressure of the working liquid in the main cylinder, and the movements of the mold. Equipping of a P-907 hydraulic press with recording instruments continuously recording the changes in the full and dynamic pressures of the working liquid makes it possible to provide reliable continuous control of the stability of the operating parameters of the press, to simultaneously reveal breakdowns in the hydraulic system of the press and promptly eliminate faults in deviation of the press operating parameters from the specified, to obtain objective information for a shift-by-shift analysis of the reasons for downtime of the press equipment, and to provide the conditions for control and centralization of control of the production operation.

    Mechanism of wear of electric arc steel melting furnace wall linings and means of increasing their life (1988)
    Springer
    Refractories and industrial ceramics 29 (1988), S. 128-130 
    Details
    ISSN: 1573-9139
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Conclusions The walls of electric arc steel melting furnaces and especially the region of the slag belt operate under very severe conditions. Together with physicochemical factors the life of the lining is also determined by the design of the refractory shell of the working space of the furnace and the ratio of its primary dimensions. A method of increasing the wall refractory lining life as the result of rational construction in the design of new and reconstruction of existing furnaces was proposed.

    Compactibility of periclase mixtures (1996)
    Springer
    Refractories and industrial ceramics 37 (1996), S. 92-94 
    Details
    ISSN: 1573-9139
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract Special equipment is used to investigate the pressing regimes of periclase mixtures with different grain compositions. The pressing pressures are presented as a function of the time of action of the load. The dynamics of the variation of the mean density is presented as a function of the pressing time and the pressing pressure. The compactibility of the mixtures is evaluated from the corresponding criterion.

    Forging of P/M parts with counterpressure using the principles of mathematical modeling (1985)
    Springer
    Powder metallurgy and metal ceramics 24 (1985), S. 266-269 
    Details
    ISSN: 1573-9066
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Conclusions A mathematical model of the forging process has been developed. Analysis of this model shows that the principal factors influencing the strength of parts are the pressure head, temperature of heating for forging, degree of extrusion, and the relationship between the degree of extrusion and preform density. The highest mechanical characteristics in parts from iron powder are ensured at the following parameters (within the ranges investigated): specific counterpressure 80MN/m2, temperature of heating of preforms for forging 1250°C, preform density 5.1·103 kg/m3, and coefficient of extrusion 1.78. The experimental results obtained can be utilized in the development of a process for the production of parts from P/M preforms by forging with counterpressure.
