Полученные данные позволяют предварительно по размеру и форме кусков шихты оценить вероятный прогноз поведения ваграночной плавки. Сделан вывод о том, что при переходе на антрацит и тощие угли для увеличения силы трения шихты о стенки необходимо тщательно подготавливать шихту до получения минимальных размеров кусков 0,07 – 0,08 м, что резко снижает угол зацепления и, следовательно, угол внутреннего трения и увеличивает коэффициент бокового давления на стенки шахты.</p></abstract><trans-abstract xml:lang="en"><p>The article presents the analysis of the forces acting on a coke packing or coal fuel nozzle into the cupola by replacing coke with anthracite and lean coal. The obtained data allow estimating preliminarily in size and shape of burden pieces a probable forecast of cupola melting behavior. The conclusion is that by the transition to the marks of coals to increase the frictional force on the wall of charge, the charge itself must be carefully carve into minimum pieces, which reduces drastically the angle of the engagement and consequently the angle of internal friction coefﬁcient increases as well as the pressure on the side wall of the shaft.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>вагранка</kwd><kwd>кокс</kwd><kwd>антрацит</kwd><kwd>тощие угли</kwd><kwd>столб шихты</kwd><kwd>угол внутреннего трения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cupola</kwd><kwd>coke</kwd><kwd>anthracite</kwd><kwd>lean coal</kwd><kwd>post charge</kwd><kwd>angle of internal friction</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">Kesseler K. // Stahl u.
