3.
The internal diameter of described electrode body is Ф 35-60mm, and external diameter is Ф 70-150mm, and height is 60-200mm.
The thickness of described compacted zone is 1-2mm; Described compacted zone comprises the interior layer that is attached on electrode body and is positioned at the extexine on interior layer, and the density of described extexine is 1.2-1.35g/cm
3, the density of interior layer is 0.95-1.15g/cm
3.
Described compacted zone is the compacted zone by adopting chemical vapour deposition (CVD) density method to form on electrode body surface; Described electrode body surface is all coated with compacted zone.
Described electrode body comprises cylindrical hollow part, and the inner surface of described electrode body is provided with internal thread, and its hollow space forms screwed hole; Described screwed hole comprises M50 * 3 screw thread of the portion of being located thereon and is positioned at M45 * 3 screw thread of its underpart.
Described carbon carbon electrode is arranged on electric resistor heating type high temperature furnace, electric resistor heating type high temperature furnace also comprise heater with and copper electrode; Described carbon carbon electrode connects heater and and copper electrode.
The utility model mainly replaces original normally used graphite electrode with carbon carbon composite electrode, utilizes suitable technique, and carbon carbon composite is made to gradient density electrode, and surfaces externally and internally density is high, and intermediate density is low; Make the existing surface strength of the utility model, there is again good electric conductivity.
Compare with existing graphite electrode: because body of heater is increasing now, the weight of heater itself enlarges markedly, and graphite electrode intensity is low, very easily cause connecting portion fracture, can not meet the demand of the weight of bearing large-scale heater; Graphite electrode internal resistance is large, easily causes local current too high and beat arc, and energy consumption is high, and installation, maintenance bothers very much.The utility model carbon carbon electrode intensity is high, the weight that can bear large-scale heater; Internal resistance is relatively little, is not easy to beat arc because local current is too high, and energy consumption is low, easily installs.
