Description

Предметом изобретени   вл етс  способ изготовлени  фитильных электродов дл  дуговых ламп путем прессовани  электродной массы из смеси графита, сажи и каменноугольного пека с заложенным в эту массу фитилем в виде стержн , состо щего из смеси жидкого калиевого стекла и графита.The subject of the invention is a method of making wick electrodes for arc lamps by pressing an electrode paste from a mixture of graphite, carbon black and coal tar pitch with a wick embedded in this mass in the form of a rod consisting of a mixture of liquid potassium glass and graphite.

Согласно изобретению, с целью образовани  прочного монолитного издели  фитиль перед закладыванием его в массу подогревают до 200° С. Тем самым прессуема  масса подогреваетс  гор чим фитилем, и св зующий материал (иек) эффективно св зывает частицы графита и сажи.According to the invention, in order to form a solid monolithic product, the wick is heated to 200 ° C before being laid in the mass. Thus, the pressed mass is heated by a hot wick, and the bonding material (ic) effectively binds the particles of graphite and soot.

На фиг. I-5 показаны п ть последовательных операций процесса изготовлени  электродов по предлагаемому способу.FIG. I-5 shows five consecutive operations of the electrode fabrication process according to the proposed method.

Прессование осуществл етс  в прессформе, состо щей из основани  / и двух боковых щек 2 и 3.Pressing is carried out in a mold consisting of a base / and two side cheeks 2 and 3.

При первой операции (фиг. 1) в прессформу засыпаетс  половина порции порошка 4, состо щего из графита, сажи и каменноугольного пека.In the first operation (Fig. 1), half of a portion of powder 4, consisting of graphite, carbon black and coal tar pitch, is poured into the mold.

8 Свод в. 5.8 Code in. five.

Зател в прессформу вставл ютс  направл ющие линейки 5 и 5 (фиг. 2), и в щель между ними опускаетс  фитиль 7, подогретый до 200° С. Направл ющие линейки 5 и 6 позвол ют уложить фитиль точно в середине электрода.The guide bars 5 and 5 (Fig. 2) are inserted into the mold, and a wick 7, heated to 200 ° C, is lowered into the gap between them. The guide bars 5 and 6 allow the wick to be placed exactly in the middle of the electrode.

После этого линейки 5 и 6 вынимаютс  (фиг. 3), и засыпаетс  втора  половина порции порошка (фиг. 4). Наконец вводитс  иуансон 8 (фиг. 5) и производитс  прессование при давлении в 200 кг на квадратный сантиметр и температуре 23-25° С.After this, lines 5 and 6 are taken out (Fig. 3), and the second half of the powder portion is poured (Fig. 4). Finally, Iwanson 8 (Fig. 5) is introduced and pressing is performed at a pressure of 200 kg per square centimeter and a temperature of 23-25 ° C.

При прессовании св зующа  часть массы (пек) плавитс  и схватывает частицы графита и сажи, образу  прочную монолитную массу.When pressed, the binding part of the mass (pitch) melts and seizes particles of graphite and soot, forming a solid monolithic mass.

После прессовани  прессформа разбираетс , электрод Э вынимаетс  и направл етс  в обжиг.After pressing, the mold is disassembled, the electrode E is removed and sent to the calcination.
