箱式或井式电阻炉电热丝接头与接线杆焊接,原采用在接线杆端部中心打一孔,插入电热丝头后焊牢。这样接法由于接头处承受电流大,加之高温蠕变伸缩和人工装拆修理的外力作用,接头经常折断,常需停炉焊修。现我们将接线杆一端铣一与电热丝外径相同的扁槽,深50毫米。将电热丝头60毫米处用气焊枪烧红弯成双股并拢,插入槽内,两侧空隙处和端部焊牢。使用新焊接法,因接头处有双股电
Box or well resistance furnace heating wire connector and the terminal bar welding, the original use of the center of the terminal rod to play a hole, insert the electric wire head after welding. This connection due to the joint at the current withstand large, combined with high temperature creep telescopic and artificial demolition repair the external force, the joints often break, often need to shut down furnace repair. Now we will one end of the wiring rod milling a flat wire with the same diameter heating wire, 50 mm deep. The electric wire head 60 mm with a gas torch burning red bent into double shares close together, into the slot, both sides of the gap and the end of the prison. The use of new welding method, due to the joint at the double-stranded electricity
