Description
В электрических печах дл восстановлени вольфрамового ангидрида водород ввод т в одном месте, и он перемещаетс в направлении, встречном движению контейнеров с ангидридом. Такой способ подачи водорода ограничивает длину печи и, следовательно, вл етс преп тствием дл увеличени ее производительности, так как с увеличением длины печи соответственно увеличиваемое количество водорода при такой подаче резко мен ет температурную кривую, смеща максимум ее к середине печи, что приводит к. нарушению всего режима технологии и получению некондиционной продукции.In electric furnaces for the reduction of tungsten anhydride, hydrogen is introduced in one place, and it moves in the direction opposite to the movement of containers with the anhydride. This method of supplying hydrogen limits the length of the furnace and, therefore, is an obstacle to increasing its performance, because with increasing furnace length, the corresponding increase in the amount of hydrogen during this feed dramatically changes the temperature curve, shifting its maximum towards the middle of the furnace, which leads to. violation of the whole mode of technology and obtaining substandard products.
Предлагаемый способ подачи водорода в муфельные или трубчатые печи дл восстановлени вольфрамового ангидрида, заключающийс в том, что водород ввод т в нескольких местах но длине печи (см. фиг. 1) позвол ет увеличить длину печи и благодар этому подн ть ее производительность , а также сократить производственные площади.The proposed method of supplying hydrogen to muffle or tube furnaces for the reduction of tungsten anhydride, which means that hydrogen is introduced in several places but the length of the furnace (see Fig. 1) allows the furnace to increase its length and thereby increase its capacity, as well as reduce production space.
В печах пр мого нагрева муфел током, подвод щие ток щины могут быть совмещены с подвод щими водород трубами (см. фиг. 2).In furnaces of direct heating of the muffle with current, the supply current can be combined with the supply pipes with hydrogen (see Fig. 2).
