Annotation

The article compares the quality of the working surface of the sleeve of the mold, obtained after turning, and after pulling the mandrel. A study of the microgeometry of the surface of copper shells of the mold after turning and broaching was performed based on international standard DIN4776 using the Abbot curve. Was carried out nonparametric estimation of the profile, which gave the opportunity to establish not only its high-rise and periodic characteristics but also the form of the microrelief, which significantly affects the performance properties of the surface. It is established that the surface of the liner after pulling has a plateau-like relief, resulting in high wear resistance.

Keywords: continuous casting machine of billets, liners, molds, quality, surface layer, surface.

The interrelation of sugar beet factory departments is not always fully described in the scientific and technical literature. Sugar beet processing indicators controlled at one stage don’t always fully reflect the further course of the technological process in subsequent stages. The article describes the technological parameters controlled at the stage of obtaining the diffusion juice, namely shape of the beet chips, Silin number, modulus of elasticity, pH of the extractant of diffusion process and their subsequent influence on pressing of beet pulp.

Annotation

According to the Union of Sugar Producers “Rossahar”, the selling price per kilogram of sugar in Russia in March 2018 was about 32 rubles, while on the London exchange at the average exchange rate – about 24 rubles. The high cost of domestic product practically completely deprives its competitiveness at the world level. In addition with technical condition of the equipment and the qualification of the personnel, the quality of the sugar beet entering the processing has an important role in the production efficiency. It is impossible to have high production figures at low technological quality of sugar beet. The article compares the main factors influencing the yield of sugar beet, according to the opinion of Russian and German scientists, gives the characteristics of root crops with low technological quality and describes their influence on the technological process.

Keywords: sugar beet, technological quality, yield, sugar content, molasses, herbicides, growth stimulants, sugar loss.

On the standard for the selection of monoliths of weak primes from drilling wells by immediate grant-soils GMT-100 and GMTT-100

V.V. Denisenko, P.A. Lyashenko
Annotation

For the selection of monoliths of weak soils, many designs of indented soil were created. However, most of the known primers for the selection of monoliths of weak soils do not ensure the preservation of the natural addition of soils in the selected monoliths, they have various design and technological disadvantages. The authors developed indented soil-bearing GMT-100 and GMTT-100 and a standard for the selection of monoliths of weak soils from boreholes with their help. In the standard, the design of the pressed primers GMT-100 and HMTT-100 and the technology of selection of monoliths of weak soils with their help are given. The efficiency of GMT-100 and GMTT-100 ground-bearers is confirmed by the results of their use at production facilities of the SevKavTISIZ enterprise for engineering and construction surveys for the selection of monoliths of weak soils in combination with static sounding at the same sites.

Methods of ground testing with a constant load speed and constant speed of deformation

E.V. Kravchenko, V.V. Denisenko, I.V. Budagov, P.A. Lyashenko
Annotation

The standard method of compressive soil compression, which consists in applying a load on the ground with steps with each holding to stabilize the deformation of the soil, is simple in implementation, but does not correspond to the loading regime of the foundation soil during construction, in which the load increases in time almost continuously. The method of constant loading speed (PSS method) allows to analyze in more detail the compressibility of soils, using the rate of deformation of soils and the cyclic nature of its changes. The method of constant deformation rate makes it possible to analyze the cyclicity of the change in the ground force reaction to the load. The greatest correspondence to the regimes of loading the foundation soils during construction is provided by the SPE method.

Keywords: stepwise increasing load, constantly increasing load, constant strain rate, soil sample, sample sediment.

Phase equilibrium in binary mixtures water – 1-butanol and ethanol – 1-butanol

T.G. Korotkova, A.A. Glytyan
Annotation

A comparison of the phase equilibrium in the systems of vapor – liquid and liquid – liquid of the literature experimental data with the calculated models obtained by the group composition of UNIQUAC and NRTL for heteroazeotropic mixture “water – 1-butanol” and non – azeotropic mixture “ethanol-1-butanol” at atmospheric pressure. Both models accurately predict the equilibrium in the vapor – liquid system. The relative error of calculation of the azeotrope point is about 5%. The parameters of the NRTL model are predicted by the properties of pure components. Good quantitative and qualitative agreement between experimental and calculated data is obtained. The compositions of the equilibrium phases with delamination of the “water – 1-butanol” mixture are described with a large error when using the NRTL method.

Keywords: water – 1-butanol, ethanol – 1-butanol, phase equilibrium, distillation, delamination.

Phase equilibrium of the mixture of water – 1-butanol – ethanol

T.G. Korotkova, A.A. Glytyan
Annotation

The calculated data of the equilibrium compositions of the “water – 1-butanol – ethanol” splitting mixture are calculated using the NRTL method at various temperatures at atmospheric pressure. As the energy parameters of the binary interaction, the built-in parameters of the Hysys package, designed for modeling complex chemical-technological systems, as well as parameters predicted by the parameters of intergroup interaction of the UNIFAC model, are adopted. Calculations are made in the language of Borland Pascal. The calculated data are compared with the literature experimental data obtained on the basis of modern methods of analysis of equilibrium compositions. The best description at low temperatures gives the predicted parameters, but the heterogeneous region under the binodal curve is overestimated. According to the experimental data, at a concentration of ethanol in the mixture above 12% mole, the “water – 1-butanol – ethanol” mixture is homogeneous.

Keywords: water - 1-butanol - ethanol, phase equilibrium, delamination.

Features of development of cadastrovo-estimation works in Ancient Egypt

A.S. Pshelintseva
Annotation

The purpose of the article is to investigate by the narrative method the skills of compiling and maintaining the first known land cadastral systems for the most rational management of the modern cadastre. An example is taken of Ancient Egypt. The land sciences of Egyptian priests – geodesy, geometry, irrigation farming, etc., have been so named, adopted, ordered and supplemented by the ancient Greeks and subsequently by the Romans. The first land lists were recorded in the time of the first pharaohs in the fourth millennium BC. Subsequently, the classification of soil types was carried out depending on yield (kait, tany, neheb, etc.) and subsequently had a more detailed justified structure. A distinctive feature of the land system of Ancient Egypt was the high yield as the main feature of the type of management “Asian way of production”, described by Karl Marx.

Keywords: land cadastre, Ancient Egypt, geodesy, geometry, soil quality, soil composition, Asian mode of production, irrigation system.
