How did the appearance of the graphite electrodes change?
By:Win Nov 12, 2020
The appearance machining of graphite electrode is divided into two independent machining of body and nipple.
Graphite electrodes are made of petroleum coke, needle coke, etc. as raw materials, coal tar pitch, etc. as binders, through raw material crushing, batching, mixing, compression molding, roasting, impregnation, secondary roasting, graphitization, machining, quality inspection, It is prepared in 11 processes including packing and leaving the factory, with many production processes.
Graphite electrodes structure drawing, It's composed of body and nipple.
Graphite electrodes machining
The purpose of graphite electrode appearance machining is to meet the requirement of size, shape and precision. Dan carbon graphite electrode machining equipment: 4 CNC lines for electrode and nipple machining.
Graphite electrode body processing includes borehole, cylindrical turning and thread milling.
CNC lines for electrode machining
The processing of graphite electrode conical nipple can be divided into six procedures: cutting, flat end face, turning cone face, milling thread, drilling anchor and grooving.
The electrode machining accuracy is strictly controlled, and it needs to be noted that: thread taper deviation, thread pitch, joint (hole) large diameter deviation, joint hole coaxiality, joint hole perpendicularity, electrode end face flatness, joint four-point deviation, etc. Should use special ring gauge and plate gauge to check whether to meet the standard.
