Представлены результаты измерения геометрии и расположения трещин в объеме брикетов, полученных методом валкового брикетирования. Возможность появления трещин в объеме брикетов является технологической особенностью валкового брикетирования. Этот дефект влияет на прочность брикетов, а также на выход годного (и производительность) в процессе брикетирования на валковых брикетировочных прессах. Количество и угол наклона трещин относительно направления брикетирования определено по фотографиям боковой поверхности брикета с использованием графических программ.</p></abstract><trans-abstract xml:lang="en"><p>This paper examines the crack geometry of briquettes in magnesium oxide (MgO), a slagging material widely used in iron and steel making applications. Geometry measurement data and crack layout in briquettes are produced by roll briquetteizing. Cracking in briquettes is likely due to the workflow of roll briquetteizing. This defect affects the strength of briquettes and yield ratio (plus productivity rate) during briquetteizing using roll baling presses. A number and angles of cracks in respect to the briquetteizing direction were identified in accordance with photos of briquette side surfaces using graphical software.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>брикет</kwd><kwd>валковое брикетирование</kwd><kwd>оксид магния</kwd><kwd>трещины</kwd><kwd>угол наклона трещины</kwd><kwd>прочность брикетов</kwd><kwd>максимальное касательное напряжение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>briquette</kwd><kwd>roll mill briquetteizing</kwd><kwd>MgO</kwd><kwd>cracks</kwd><kwd>crack angle</kwd><kwd>briquette strength</kwd><kwd>maximum tangential stress</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">Dec R.T., Zavaliangos A., Cunningham J.C.
