Calculate the tense-deformed state of two ortogonal attended plates through special the built matrices of Grina type. \u0000Research methods. Bases of theory of laminas, apparatus of trigonometric rows of Fourier, methods: border-component tasks, variation of arbitrary permanent, matrices of Grina type. \u0000Results. A task of elastic elastic equilibrium of plate pairs connected at right angle was considered. On parallel edges of component body to connection rib special edge conditions – conditions of symmetry – were chosen. From the physical point of view the probed body can be the model of lateral walls of parallelepiped. It is provided the special terms of symmetry on both edges of component body, which are parallel to the rib of connection of plates. The method of calculation allows to calculate the tense-deformed state of spatial construction consisting of two plates in edge conditions of arbitrary surface loading. The results of calculation (as lines of level) of basic characteristics of static deformation of considered rectangular connection of two plates are given. \u0000Scientific novelty. The method of calculation of pair of plates, united at right angles was improved at the regional terms of symmetry, with subsequent graphic illustration of achived results. \u0000Practical value.

Determination of the gas-dynamic parameters of the injection of powdered reagents to provide high-performance operation of devices for powder ferroalloys injection deep into the metal in a teeming ladle. Research methods. An analytical review of literary sources has been carried out, the results of which have arguably confirmed the advantage of the powder reagents injection into the ladle in comparison with traditional deoxidation and alloying technologies. Based on well-known mathematical models adapted to specific technologi-cal conditions, mathematical modeling has been carried out, which takes into account a number of parameters important for the technology, in particular, the degree of powder assimilation and the carrying capacity of the carrier gas. Results. Based on the results of mathematical modeling, the rational modes of powdered ferromanganese injection into the teeming ladle and the size of its fraction, which provides both a high assimilation degree of powder particles by a liquid metal melt and prevents the deposition of powder particles on the walls of the pipeline have been determined by mathematical modeling. Scientific novelty. Based on the results of mathematical modeling, the peculiarities of the interaction of a gas suspension jet with liquid metal melts have been specified. Practical value. The gas-dynamic parameters of the process of of powdered ferroalloys are determined, which provide high performance of the deoxidation and alloying of steel in the teeming ladle, reliable operation of lances and nozzles for powders injection deep into the metal and interaction of particles with metal, necessary from the point of view of deoxidation kinetics.","PeriodicalId":423067,"journal":{"name":"Innovative Materials and Technologies in Metallurgy and Mechanical Engineering","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134244228","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
