В ходе промышленных исследований выявлены основные дефекты рабочей поверхности разливочного колеса, образующиеся в процессе его эксплуатации: поперечные трещины, располагающиеся на рабочей поверхности в плоскостях, перпендикулярных направлению разливки, – как на основании трапеции, так и боковых гранях (длина трещин составляет 10–45 мм с расстоянием между ними 7–40 мм); выбоины, продольные углубления и царапины, наблюдаемые вдоль направления движения заготовки преимущественно в тупых углах трапеции и областях, прилегающих к ним; деформация профиля колеса в углах рабочего канала, обусловленная, прежде всего, износом вследствие трения. Установлено, что основными причинами формирования поверхностных и внутренних трещин в колесе являются сложные температурные режимы работы, связанные с технологией разливки меди на МНЛЗ роторного типа. Чередующиеся циклы нагрева и охлаждения отдельных участков разливочного колеса приводят к возникновению двумерных растягивающих напряжений в его внутренних слоях, вследствие чего образуются трещины. Не менее важным фактором появления трещин следует считать последующее чрезмерное вторичное охлаждение колеса водой, поскольку за ним следует повторный нагрев поверхности заготовки. Вместе с тем снижение градиента температур поверхности колеса между зонами охлаждения будет способствовать уменьшению степени деформации его поверхности и увеличению срока эксплуатации, а также повышению качества непрерывнолитой заготовки и готового проката.</p></abstract><trans-abstract xml:lang="en"><p>The paper presents the results obtained when studying how the condition of the casting wheel working surface in the rotary continuous casting machine (CCM) influences the quality of copper metal products on the Southwire modern high-tech continuous casting and rolling line at PJSC «Artemovsk Non-Ferrous Metals Processing Works». Industrial research identified the main defects occurred on the casting wheel working surface during its operation: transverse cracks located on the working surface in planes perpendicular to the casting direction – both at the trapezoid base and on its side faces (10–45 mm long cracks located 7–40 mm apart); dents, longitudinal dimples and scratches along the direction of billet movement mainly in the obtuse angles of the trapezoid and in areas adjacent thereto; deformed wheel profile in the corners of the working channel, primarily due to friction wear. It was found that the main causes of surface and internal cracks in the wheel are challenging temperature modes of operation associated with the technology of copper casting on the rotary CCM. Alternating cycles of heating and cooling of individual sections of the casting wheel cause two-dimensional tensile stresses in its internal layers resulting in cracks. An equally important factor in crack formation is further excessive secondary cooling of the wheel with water as it is followed by reheating of the billet surface. However, a lowered temperature gradient of the wheel surface between the cooling areas will reduce the degree of surface deformation, increase the service life and improve the quality of continuously cast billets and finished steel.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>разливочное колесо</kwd><kwd>кристаллическая структура</kwd><kwd>скорость разливки</kwd><kwd>дефекты поверхности</kwd><kwd>поперечные трещины</kwd><kwd>внутренние напряжения</kwd><kwd>конечно-элементное моделирование</kwd><kwd>тепловое состояние</kwd><kwd>интенсивность деформаций</kwd><kwd>напряжения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>casting wheel</kwd><kwd>crystal structure</kwd><kwd>casting rate</kwd><kwd>surface defects</kwd><kwd>transverse cracks</kwd><kwd>internal stresses</kwd><kwd>finite element modeling</kwd><kwd>thermal state</kwd><kwd>deformation intensity</kwd><kwd>stresses</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Southwire copper rod systems.
