CONSTRUCTIONAL MATERIALS, PHYSICAL METALLURGY

Kovalenko I. V., Kovalchuk N. A., Landikov Yu. V. — The study of low-cycle fatigue of the fastening material for the ship main engine

The article presents the methods and approaches to determining the magnitude of low-cycle fatigue arising in the junctions of the main engine to the hull. The approaches to the determination of the mechanical properties of a two-layer welded joint are described.
The evaluation criteria of the testing results for determining the number of loading cycles before the detection of the samples failure primary signs, as well as before the leakage, that is until complete destruction of the sample are considered. The analysis of the final values of the samples test both by the number of sustained cycles and by the intensity of crack development is carried out.
Key words: sample, two-layer steel, loading cycle, crack, fatigue, mechanical load, fracture

BLANK PRODUCTION

Nizhegorodov A. I. — Technical evolution and efficiency indicators of the electric furnace for burning of vermiculite concentrates and conglomerates

The article provides an analytical review of developments in the field of electric furnaces for firing vermiculite concentrates and conglomerates. The article deals with the improvement of the first module-launching units in the process of their development since 2003, when they first appeared (the energy intensity of firing was achieved 196.0 MJ/m3), until 2014, when there was a transition to fundamentally different energy-technological AG — regattas-furnaces with a vibrating hearth platform, which showed the possibility of achieving a specific energy intensity of firing vermiculite about 55.6 MJ/m3. It is shown that such furnaces are competitive, since their specific energy consumption is more than four and a half times less than that of the best fire furnace operating on hydrocarbon fuel.
Key words: electric kiln, vermiculite concentrate, module and trigger unit, the specific energy of the kiln

Anakhov S. V., Pykin Yu. A., Matushkin A. V. — Methods of calculating and designing plasma torches for cutting metals

Author's results on development of a computation procedure and designing for metal-cutting plasmatrons are generalized and systematized. It is noted, that the similar technique should be based on functional, systemic and optimal principles. Special attention at designing it is necessary to turn on gas-dynamic factors and safety of plasma technologies. The offered technique includes calculation of gas-dynamic losses and plasma gas uniformity in cross-section of an air-gas path. The results of gas-dynamic analysis are used for profiling an air-gas path in view of safety criteria. The considered technique is applied for new plasmatrons development, including narrow jet plasma technology.
