| Description |
На основі термодинамічного аналізу встановлено, що на поверхні частинки неметалевих включень утворюються плівки металу, що змочують їх та перешкоджають подальшій коагуляції та видаленню неметалевої фази. Визначено, що для запобігання дії плівок, що змочують, необхідно створювати перемішування у проміжному ковші. Проведене фізичне моделювання гідродинамічних процесів у проміжному ковші дозволило встановити, що найефективнішою структурою потоків є вихороподібна, яка утворюється за рахунок встановлення реакційної камери. Результати промислових випробувань добре узгоджуються з даними фізичного моделювання та теоретичних висновків.
Using the thermodynamic analysis, the possibility of a colloid interaction of the dispersed phase with a dispersed medium, the possibility of coagulation of the non-metallic phase, has been determined. It is established, that on the surface of a particle of nonmetallic inclusions metal films (layers) are formed that “wet” them and prevent further coagulation and removal of the non-metallic phase. It has been determined, that in order to prevent the effect of “wetting” by these films (layers), it is necessary to create mixing in the tundish. Based on the theoretical principles of removing non-metallic inclusions, a physical modeling of the hydrodynamic processes occurring in the tundish, has been carried out. These studies have made it possible to establish, that the most effective structure of streams is a vortex, which is formed by the introduction of a reaction chamber. For confirmation of theoretical conclusions and results of physical modeling, industrial tests were conducted to determine the contamination of the metal by the non-metallic inclusions. The test results correspond well with the data of physical modeling and theoretical conclusions. |
