Abstract
Изобретение относитс к устройству дл термообработки длинномерных изделий. Цель изобретени - повышение качества обработки путем повышени равномерности нагрева и обеспечение возможности обработки любого участка длинномерных изделий. Нагреватели, расположенные в вакуумной камере 1, представл ют собой подвижные секции 4 с экранами 6, перемещающиес по токоподводам 5. Кажда секци 4 имеет перфорированный корпус с равномерно расположенными по его сечению нагревательными элементами, причем последние образуют правильные шестиугольники с обеспечением свободного прохода изделий. Локальный разогрев изделий осуществл етс с высокой равномерностью независимо от расположени изделий относительно центральной оси камеры 1. 3 ил.The invention relates to a device for heat treatment of long articles. The purpose of the invention is to improve the quality of processing by increasing the uniformity of heating and ensuring the possibility of processing any area of long products. Heaters located in the vacuum chamber 1 are movable sections 4 with shields 6 moving along current leads 5. Each section 4 has a perforated housing with heating elements evenly spaced along its cross section, the latter forming regular hexagons ensuring free passage of products. Local heating of the products is carried out with high uniformity regardless of the location of the products relative to the central axis of chamber 1. 3 sludge.
