Deste modo, tivemos como objetivo principal pensar a tecnologia e suas implicações, bem como o lugar da ludicidade na articulação do compreender-se lúdico e tecnológico para além dos instrumentos na educação contemporânea e no contexto escolar.  Assim, o traçado metodológico deste estudo teve a pesquisa qualitativa como abordagem essencial. Os resultados apontaram a presença do lúdico nos processos formativos como ação essencial para o fazer pedagógico dentro dos espaços escolares, no qual os aspectos lúdicos e tecnológicos podem caminhar em sintonia, pois são práxis indissociáveis e, sobretudo, a tecnologia aqui é entendida para além da racionalidade instrumental.
educação superior contemporânea em tempos de luta por inclusão no sistema de ensino brasileiro
Authors: Souza da Silva Jackeline Susann , Carvalho Maria Eulina Pessoa
Published: April 2021

Este artigo é um recorte de uma investigação de mestrado que tem como objetivo analisar as políticas de inclusão nas instituições de ensino superior (IES) brasileiras. O período delimitado é a primeira década do século XXI – momento em que houve a publicação do Plano Nacional da Educação-PNE (2001-2011) e, com isso, o lançamento de programas para a ampliação do acesso de grupos específicos aos cursos superiores. Este estudo se desenvolveu, primeiramente, por meio de um levantamento do Censo divulgado pelo Instituto Nacional de Estudos e Pesquisas Educacionais Anísio Teixeira-INEP e pelo Instituto Brasileiro de Geografia e Estatísticas-IBGE. Na segunda parte, foi feito um mapeamento dos principais programas de transição para o ensino superior, tais como FIES; PROUNI e Programa Incluir. Os resultados demonstram que a ascensão à educação universitária não é uma extensão natural na vida escolar de grupos específicos, como a população negra e as pessoas com deficiência. De fato, houve a expansão da educação superior, contudo, o aumento das vagas não superou a meta do PNE. O setor privado concentra o maior número de matrículas de estudantes de baixa renda e com deficiência, o que indica que proposta de inclusão universitária atende, de modo prioritário, aos interesses do mercado educacional.
ЧИСЕЛЬНІ ДОСЛІДЖЕННЯ НА МАТЕМАТИЧНІЙ МОДЕЛІ СПІНЕННЯ З ІНЖЕКЦІЄЮ ГАЗУ
Authors: Красніков Кирило , Лижов Микита
Published: April 2021

Кисневі конвертори часто використовуються у виробництві сталі для видалення вуглецю з чавуну за допомогою продувки киснем та для розплавлення металобрухту. Шлак на поверхні розплаву всередині конвертора уповільнює газові бульбашки, що утворює велику кількість емульсії або піни. Іноді рівень піни може перевищувати ви-соту конверторної ванни. Щоб запобігти цьому, металургам потрібно прогнозувати подібні ситуації та відповідно зменшувати вдування газу в небезпечні періоди. Після багатьох років використання кисневих перетворювачів металурги отримали досвід і знають безпечні режими цього процесу. Однак ці режими можна вдосконалити за до-помогою математичного моделювання, яке користується популярністю в наші дні, оскільки воно має менші витрати, ніж реальні експерименти на заводі чи в лаборато-рії. Гідродинамічні процеси в конверторі складні, тому математична модель повинна уникати надмірного спрощення та враховувати важливі деталі про них. У попередній роботі представлена модель з детальним описом рівнянь (Нав'є-Стокса) та граничних умов. Чисельне рішення простіше отримати, ніж аналітичне для такої складної моде-лі. Для перевірки адекватності моделі використовуються такі припущення: загальна кількість газу повинна бути збережена у випадку закритого об'єму, а також поле ти-ску повинно збільшуватися відповідно до отриманої кількості газу; у разі переміщення вільної поверхні рівень піни повинен змінюватися відповідно до приходу газу і поверта-тися до початкового значення після того, як весь газ піде з рідини.Представлені малюнки ілюструють зміну рівня піни у випадку, коли газ надходить у розплав протягом перших 20 секунд з лінійним зниженням до нуля через 20 секунд. Об-числювальна область має 72x144 комірок. Ефективність обчислень знижується, коли рівень піни зростає, оскільки в розрахунку бере участь більше клітин. На інших рисун-ках показано газове поле (кольором) і поле швидкості (стрілками) для двох випадків: коли об’єм закритий і коли поверхня розплаву рухається. У закритому об’ємі зазначені вище припущення перевірено та подано графік залежності кількості газу. На основі цього зроблено висновок про якісну адекватність моделі. 2D-візуалізація здійснюється у комп’ютерної програми, розробленої на популярній мові.

The article presents a method of designing the process of interaction of three enterprises in a single production system. The matrix method of dynamic programming establishes calculation formulas for design parameters: the share of the flow of gross output, which is sent by enterprises for the development of their own production. The quadratic functional is accepted as a criterion of optimality, the physical meaning of which is the expenditure of funds to support the stable functioning of the process. In this case, the final product of the production system, sent to external consumption should be maximum. The software product is created and the optimum decision is received. Modeling in the modeling system of MVTP 3.7 of the process of interaction of three enterprises for three variants is performed. The option with optimal design parameters provides an increase in the production capacity of enterprises and corresponds to the area of rational values of the shares of intermediate products of enterprises, which is established by modeling.

Authors: Balakin Valery , Stasevsky Stanislav , Ugryumov Yuri
Published: April 2021

In this work, based on the analysis of the process of hot pilger rolling of pipes of a wide range of sizes and grades from a round continuous cast billet, new and improved existing metal-saving technologies have been developed to reduce metal losses in the pilger head.Using scientific and patent sources of information in the field of pilger rolling and its mathematical modeling with the calculation of tables for rolling pipes of a wide range of sizes from a round continuous-cast billet with a diameter of 385-470 mm, metal losses into technological scrap on a pilgerstan are determined: a seed and a pilger head.On the basis of the results of the theoretical determination of metal losses in the process scrap on the pilgerstan: the seed and the pilger head, a forecast was made to reduce the weight of the pilger head, which was used to develop new material-saving technologies for pilger rolling of pipes, both thick-walled with D / S = 6 - 12.5, and thin-walled with D / S = 12.5 - 40. Metal losses in the pilger head are the main factor of increased metal consumption coefficients on pilger units, which reduces their competitiveness in comparison with other units when using round continuously cast billets as a starting material.The forecast for the reduction of metal losses in the pilger head made for the first time makes it possible to estimate the reserves for reducing the mass of the pilger head both by eliminating the underflow of the liner and trimming of the pipe end adjacent to the pilger head, and by means of individual parts of its profile part and predicting its decrease to the minimum possible size, ensuring the removal of the pipe from the mandrel using a gate device.To reduce the weight of the pilger head when rolling thick-walled pipes, it is recom-?ended to use improved technologies for butt-end rolling and rolling of the pilger head on the free section of the mandrel.The results of the studies and the proposed new material-saving technologies can be used on pilgrim units when rolling thick-walled (D / S = 6 - 12.5) and thin-walled (D / S = 12.5 - 40) pipes of a wide range of brands (carbon, alloyed, highly alloyed and special) from both continuous casting machine and forged and centrifugally cast billets, as well as ingots.

PHYSICAL MODELING OF STEEL HOMOGENIZATION DURING FINISH ALLOYING IN THE MOLD
Authors: Andriukhin Roman , Molchanov Lavr , Synehin Yevhen
Published: April 2021

The article describes the method of finish alloying steel in molds in top and bottom casting. Due to the reduction of oxygen activity in the metal due to the relatively lower casting temperature than the previous stages of steelmaking redistribution, it is achieved the reduction of the ferroalloys loss and increasing the yield of useful elements of ferroalloys. An important indicator of the implementation of the proposed technology is the alloying of steel in the mold to obtain steel of a certain brand in small volumes. The aim of the study is to determine the rational place of addition of alloys into the volume of the melt and the method of casting, for the best dissolution of alloys in steel directly in the mold. To solve this problem, the method of physical modeling on a water transparent model using a fluorescent dye that glows brightly in ultraviolet light was used. The experiment consisted of three series of with different methods of casting and introduction of dye: 1) top casting with the introduction of dye into the mold; 2) bottom casting with the introduction of dye into the mold; 3) bottom casting with the introduction of dye in the trumpet. It was analyzed that the averaging of the dye is more efficient at a lower liquid level in the mold, because mixing occurs due to the flow of liquid in the mold, the higher the liquid level in the mold, the weaker the mixing flows. The research revealed minimization of averaging time at the optimal fluid level. For top and bottom casting with the addition of dye to the mold, the optimal level is 33%. When the dye is introduced into the center, there is a slight directly proportional increase in the time of complete homogenization with an increase in the liquid level in the mold. Among the analyzed methods of steel casting, the most effective in terms of homogenization of the alloying additive is bottom casting. The color of the liquid at different stages of filling the mold with the introduction of the dye at the level of 25% of the height of the mold is analyzed.
