There was defined a formation at the surface of steel billets during the influence of fluctuating at ultrasound frequencies regular nano-structures indicator. The nano-structures form homogeneous micro layer which differs from the original one by smaller fractal dimension. The possibility to form an orientated micro layer at the surface of thermo-processed billets was shown. The micro layer allows to improve the conditions of contacting for the details of the type of matched friction pairs.

The task of mill equipment with the vibration diagnostic system is relevant because of the need to enhance maintenance efficiency and reduce essential equipment failures. The main peculiarity of vibration processes appearing in the mill process line has been distinguished: appearing longitudinal vibrations transmitted through treated metal. Furthermore, approximation of longitudinal vibration frequencies to the strip natural frequency results in resonant vibrations. It causes strip defects and may trigger fault trip of the mill due to its breakage. The paper formulates requirements to the stationary system of the mill equipment vibration monitoring. It substantiates the strategy of vibration control based on solving two functional tasks: vibration monitoring and diagnostics. Tasks of the functional sub-systems are considered. The paper also lists mill stand defects to be determined with vibration diagnostics and criteria for their detection at the early stage. It provides the example of practical implementation of the developed strategy at establishment of the stationary system for diagnostic monitoring the equipment of the main electric drives of 630 mm five-stand cold-rolling mill at OJSC Magnitogorsk Iron and Steel Works. Locations for sensor installation at the mill stand equipment have been determined. The system functional structure is under consideration. Display representation of results of parametric vibration diagnostics is provided. Results of industrial introduction of the developed system are described.

A mathematical model of the process of gasification of wood waste, which takes into account the heating step, drying, pyrolysis, combustion, recovery, and the connection between them was made. Modeling allows to determine the design parameters of the installation, the main technological parameters of the work and to forecast the parameters of a mixture of combustible gases at the exit of the gasifier.

As a result of computational and experimental study the regularities of wear of the grinding wheel working surfaces in the process of double disk grinding of bearing rings ends have been established. Adequacy of mathematical and computer models has been confirmed by a satisfactory agreement of computer simulation results and experimental data. The established regularities have laid the basis for a new method of making the working surface of grinding wheels.

Realization control volume method for calculation of non-stationary task of heat conductivity is presented in the article. This method can be applied for simulation of metal casting solidification in sand mold and other application. Distinctive feature of the developed method is possibility of application of the distributed computing which provides a good result on calculation speed, however demands the bigger volume of random access memory. In the calculation example, for a grid from 1 million elements the increase in calculation speed by 15÷20% was reached when using 2 cores of the Intel Core I-5 processor and by 30% when using 3 cores. Also there is a possibility of increase of calculations accuracy for the account of increase in quantity of calculated elements at identical calculation time.
