При прогнозировании температурных условий службы роликов обычно не принимается во внимание тот факт, что в начальный период эксплуатации ролика канал охлаждения чистый и работает в условиях, резко отличающихся от условий конечного периода эксплуатации. Непрерывно растущий слой накипи на поверхности канала охлаждения, имеющий высокие механические свойства и низкий коэффициент теплопроводности, вызывает повышение температуры рабочей поверхности до значений температуры отпуска материала роликов металлургических машин. В данной работе исследованы температурные условия службы роликов металлургических машин в условиях накипеобразования на поверхности канала охлаждения. Предложена методика оценки температурных условий службы роликов металлургических машин в условиях образования накипи на поверхности охлаждения. На примере ролика машины непрерывного литья заготовок показано, что для выбранных условий эксплуатации максимальная температура наружной поверхности ролика достигает своего критического значения через полгода работы металлургической машины. Методика позволяет дифференцированно подходить к определению средней и максимальной температуры поверхности роликов с учетом величины и характера тепловой нагрузки, условий охлаждения и накипеобразования на поверхности теплообмена. Она может служить основой для определения ресурса роликов, нормирования расхода реагентов для подготовки охлаждающей воды.</p></abstract><trans-abstract xml:lang="en"><p>The use of brackish water for indoor cooling of rollers of metallurgical machines leads to the formation of scale on the inner surface of the cooling channel. When forecasting the temperature conditions of service of rollers, the fact that in the initial period of operation of the roller cooling channel is clean and in working conditions dramatically different from those of the final period of operation, is usually not taken into account. Continuously increasing layer of scum on the surface of the cooling channel, which has high mechanical properties and low coefficient of thermal conductivity, causes a rise in temperature of the working surface to the tempering temperature of the material of metallurgical machinery rollers. The aim of this work was to study the temperature conditions of service of metallurgical machinery rollers at scale formation in the cooling channel surface. The authors have proposed a method of estimating the temperature conditions of service of metallurgical machinery rollers for this case. For example, the estimation for roller of continuous casting machine has shown that for selected operating conditions the maximum temperature of the roller outer surface reaches its critical value after six months of work of metallurgical machines. The technique allows a differentiated approach to the definition of average and maximum temperature of the surface of the rollers in view of the magnitude and nature of the heat load, cooling conditions, and scale formation on the heat transfer surface. It can serve as a basis for definition of rollers operation life and rational consumption of reagents for the preparation of cooling water.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ролики</kwd><kwd>металлургические машины</kwd><kwd>ресурс</kwd><kwd>температура</kwd><kwd>теплообмен</kwd><kwd>охлаждение</kwd><kwd>накипеобразование.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rollers</kwd><kwd>metallurgical machines</kwd><kwd>operation life</kwd><kwd>temperature</kwd><kwd>heat exchange</kwd><kwd>cooling</kwd><kwd>scale formation</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">Машины непрерывного литья заготовок.
