Получение стальных трехслойных биметаллических полос на установке совмещенного процесса непрерывного литья и деформации происходит в две стадии технологии. В статье даются рекомендации по ведению технологического процесса высокого качества. Рекомендации включают постановку задачи; исходные данные для определения температуры стальной основной полосы, напряженно-деформированного состояния металлов плакирующих слоев и полосы в очаге деформации трехслойного биметаллического слитка. Приводятся модель для расчета и методика решения задач теплопроводности и упругопластичности. Установлена закономерность изменения температуры основной стальной полосы при ее прохождении через расплав металла плакирующего слоя, определено напряженно-деформированное состояние металлов основной полосы и плакирующих слоев в очаге деформации. Авторами определены величины обжатия основной стальной полосы и взаимного смещения слоев при обжатии бойками установки биметаллического слитка, а также закономерности распределения осевых и касательных напряжений по линии контакта плакирующего слоя с бойком. Результаты исследования процесса получения биметалла сталь 09Г2С - сталь 13ХФА - сталь 09Г2С на опытно-промышленной установке непрерывного литья и деформации продемонстрировали соединение слоев без видимых в зоне контакта макродефектов, расслоений и однородную и мелкозернистую структуру металла плакирующих слоев.</p></abstract><trans-abstract xml:lang="en"><p>Today there is an urgency of creating high-performance continuous processes for the production of bimetals. The article describes the main tasks of improving the quality of the materials under consideration. Two stages of the technology for producing steel three-layer bimetallic strips on the unit of a combined continuous casting and deformation process are considered. The authors give recommendations on the conduct of the technological process in order to obtain high-quality bimetallic strips on such unit. The problem statement is presented. The material considers initial data for determining the temperature of the steel base strip and the stress-strain state of the metals of the cladding layers and the strip in deformation center of a three-layer bimetallic ingot. A model for calculating and a method for solving problems of thermal conductivity and elastoplasticity are shown. Regularities of the temperature change of the main steel strip are given during its passage through the molten metal of the cladding layer. Stress-strain state of the metals of the main strip and cladding layers in the deformation center was determined when three-layer bimetallic steel strips were obtained on the unit of combined continuous casting and deformation process. The authors describe the values of compression of the main steel strip and mutual displacement of the layers during compression of the bimetallic ingot by the strikers. Regularities of the distribution of axial and tangential stresses are shown along the contact line of the cladding layer with the striker. The evaluation of the process of obtaining bimetal steel 09G2S - steel 13KhFA - steel 09G2S was made on a pilot unit for continuous casting and deformation. Microstructure of the main strip and cladding layers of a three-layer bimetallic steel strip is shown when a combined continuous casting and deformation process is obtained in one unit.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>установка</kwd><kwd>совмещенный процесс</kwd><kwd>непрерывное литье</kwd><kwd>бойки</kwd><kwd>полоса</kwd><kwd>расплав металла</kwd><kwd>трехслойный биметалл</kwd><kwd>напряжение</kwd><kwd>деформация</kwd><kwd>плакирующий слой</kwd></kwd-group><kwd-group xml:lang="en"><kwd>installation</kwd><kwd>combined process</kwd><kwd>continuous casting</kwd><kwd>striker</kwd><kwd>strip</kwd><kwd>metal melt</kwd><kwd>three-layer bimetal</kwd><kwd>stress</kwd><kwd>deformation</kwd><kwd>cladding layer</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">Судник А.В., Петров И.В., Галиновский А.Л., Колпаков В.И., Моисеев В.А.
