Object Of Study

Purpose of research is study of the effect of the quality of the original charge on the complex of physical, mechanical, technological and corrosion properties of high-carbon tool steel U10A.Methods. High-carbon tool steel U10A, smelted at Tulachermet PJSC using metallized sponge iron pellets, scrap metal and a billet obtained by the fluidized slag blanket, has been chosen as the object of study. Steel was smelted in a three-ton arc furnace, subjected to out-of-furnace vacuum treatment in a ladle, cast into billets with a cross section of 280 × 320 mm and cooled slowly together with the furnace. Then, the obtained blanks were forged into a square of 150 × 150 mm (for making dies) and 40 × 40 mm (for samples) with cooling in sand and subsequent annealing. The experimental study of the chemical composition of U10A steel melts was determined by the method of photoelectric spectral analysis using an atomic emission spectrometer SA 2000 according to GOST 18895-97. Results. It has been found that the use of pure original charge has a positive effect on the properties of the melted metal. Steel U10A, smelted on the original charge, is not inferior in strength characteristics to steel on OMSH, surpassing the latter in terms of its plastic properties and especially in toughness. It is shown that steel smelted on the original charge is characterized by a lower content of micro-impurities, has less resistance to austenite decomposition and lower hardenability. It is revealed that, due to the lower stability of austenite, steel melted on the original charge must have a higher critical hardening rate, which should be taken into account when choosing heat treatment modes. It is established that the long-term strength of U10A steel in a medium that causes hydrogen cracking, largely depends on the heat treatment conditions and on the purity of the steel. Cleaner steel has a higher resistance to hydrogen cracking and, therefore, greater durability during operation.Conclusion. The results can be used to create resource-saving processes for processing metal alloys and composite materials.

  The article is devoted to the study of the chemical composition, physical and thermal-pfysical characteristics of damp apple pomaces and the identifying patterns of influence of drying temperature the functional composition and gel-forming ability of pectin. The research is aimed at obtaining initial data for the subsequent calculation of the main technological, hydro-mechanical, thermal, structural and economic characteristics of devices for drying the plant raw materials, ensuring the environmental safety and high quality of pectin-containing raw materials, the reducing heat and energy costs. As a result of the study of the thermal characteristics of apple pomaces, the critical points (temperature conductivity – 16.5 x 10-8 m2/s, thermal conductivity – 0.28 W/m K, heat capacity – 1627 j/(kg K)) at a humidity of 56 % are determined, which characterizing the transition from the extraction of weakly bound moisture to the extraction of moisture with strong bonds (colloidal, adsorption). It was found that the pomaces obtained from apples of late ripening have a higher content of solids (21-23 %), soluble pectin and protopectin (2.5-4.5 %). Dried pomaces obtained from apple varieties of late ripening contain up to 25 % pectin, which allow us to recommend them as a source of raw materials for the production of pectin. The optimum modes of preliminary washing of raw materials are offered, allowing to the remove the ballast substances as much as possible. It is established that when the drying temperature increases, the destructive processes are catalyzed: the strength of the pectin jelly and the uronide component and the degree of pectin esterification are reduced. The optimum drying temperature of damp apple pomaces is 80 0C, at which the quality of pectin extracted from the dried raw materials is maintained as much as possible. It is shown that the most effective for the pectin production is a fraction with a particle size of 3-5 mm, which allow us to extract up to 71 % of pectin from raw materials.

The priority in improving the existing methods of processing fish is salting with the use of food additives with different functional orientations. The aim of the study was the development of preserves with the introduction of lactate-containing additives and using sonochemical technologies; examination of the quality of the products obtained according to organoleptic and microbiological safety indicators. The article proposes a resource-saving technology for the production of fish products with prolonged shelf life due to the use of a complex food additive consisting of lactic, acetic, propionic acids and their salts in different proportions with subsequent ultrasonic treatment using the ultrasonic generator of the Wave series model UZTA-0 2/22-OM. There was established the optimal mode of using the ultrasonic processing power of 75 W / m2 in the manufacture of fish preserves from herring. Organoleptic and microbiological quality indicators were studied during storage of preserved products with the addition of additives and ultrasonic treatment compared to the control. Organoleptic assessment was carried out on a five-point scale, microbiological indicators were studied by standard methods. The Dilactin Forte Plus dietary supplement in the composition of preserves in the amount of 3% and in combination with the use of sonochemical technologies makes it possible to obtain a safe high-quality fish product. Manufactured preserves at a storage temperature of 0 ± 2 ° C can maintain their high quality for 5 months.
