Expansion of a pair of dissimilar metal shells in lined-pipe production
Globally, the working life of metallurgical products is being increased. To that end, a promising approach is the use of laminar composites. In particular, experience shows that the working life may be greatly increased by using bimetallic and lined pipe instead of monometallic pipe. Lined pipe is bimetallic pipe produced by the expansion of coaxial shells made from different materials. Little attention has been paid to lined pipe in the literature on the production of composite and bimetallic pipe. The shaping methods used in the manufacturing of lined pipe differ from those for other bimetallic pipe. These differences must be taken into account in the development of lining technologies. The lack of information regarding the shaping of the shells in lining complicates the machining of lined pipe. Therefore, the present research is devoted to the deformation and shaping of paired coaxial shells and the nonuniform strain distribution between the inner and outer shells in the lining process, as well as the influence of these factors on the ratio of strength properties of the materials in the lined pipe produced.

FEM SIMULATION OF A NEW METHOD OF LENGTHWISE PIPE ROLLING ON A STUB MANDREL WITH STRETCH
Предложен вариант усовершенствования технологии производства труб на стане продольной прокатки. Исследования проводились на базе стана продольной прокатки труб «тандем», установленного на ТПА-140 ОАО «Синарский трубный завод». В рамках снижения себестоимости поставлена задача освоения производства всего сортамента ТПА-140 из непрерывнолитой заготовки на существующем оборудовании, а также исключение из производства катаной заготовки диаметром 120,0 мм. Для освоения непрерывнолитой заготовки необходимо увеличить коэффициент вытяжки на стане продольной прокатки труб «тандем». В настоящее время коэффициент вытяжки на стане продольной прокатки труб (СПП)-1 находится в пределах 1,16 ÷ 1,5, а на СПП-2 – 1,07 ÷ 1,15. Применение больших обжатий вызывает появление продольного дефекта «риска» на поверхности труб. В работе представлены результаты исследования снижения размеров лампасов труб и, как следствие, уменьшения объема брака по дефекту «риска» за счет применения кинематического натяжения в процессе раскатки на короткой оправке предварительно овализированной гильзы. Проведено исследование влияния коэффициента кинематического натяжения на формоизменение трубы в выпусках калибра при продольной прокатке с предварительной овализацией гильзы. Установлено, что кинематическое натяжение в процессе прокатки на короткой оправке предварительно овализированной гильзы позволяет снизить интенсивность утолщения стенки гильзы-трубы в выпусках калибра при прокатке в СПП-1, что уменьшает вероятность образования продольных рисок на внутренней поверхности труб. Показана возможность увеличения коэффициента вытяжки при прокатке на автоматическом стане «тандем».

Pipe rolling on a short mandrel with kinematic tension
Improvement in pipe production on a longitudinal rolling mill is proposed. The tandem longitudinal pipe rolling mill in the pipe-mill aggregate (PMA)-140 at PJSC (public joint-stock company) Sinarsky Pipe Works is considered. Currently, pipe is produced both from rolled billet (diameter 120 mm) and from continuous-cast billet. To reduce costs, it would make sense to discontinue the use of rolled billet and to produce all of the pipe from continuous-cast billet in the existing PMA-140. In order to employ continuous-cast billet, more profound reduction in the tandem mill is necessary. At present, the reduction is 1.16–1.5 in longitudinal rolling mill 1 and 1.07–1.15 in longitudinal rolling mill 2. With greater reduction, longitudinal guide marks may appear on the pipe surface. A possible approach to decreasing the pipe wall thickening in the groove taper and hence reducing the rejection rate due to longitudinal guide marks is to employ kinematic tension in rolling an oval sleeve on a short mandrel. The influence of the kinematic tension on the pipe shaping in grooves during longitudinal rolling of an oval sleeve is investigated. This method is found to diminish the thickening of the sleeve wall in the groove taper in longitudinal rolling mill 1. That lowers the likelihood of longitudinal guide marks on the pipe’s internal surface. The possibility of increasing the reduction in rolling on an automatic tandem mill is confirmed.
