Description
Technical field
The utility model relates to charcoal graphite electrode technical field, is specially a kind of for the electrically heated a kind of graphite electrode of industrial furnace.
Background technology
In industrial production, often need to use electric heating equipment, and in these electric heating equipments, often use graphite electrode, graphite electrode is that a kind of being widely used as discharges electric energy with electrical arc in the smelting furnace of various steel alloys, ferroalloy, industrial silicon and yellow phosphorus and non-ferrous metal and rare metal and furnace charge carried out to the industrial electric conducting material of heat fused for smelting, and with factors such as its high efficiency, low cost, low faults, has surpassed other most heating system.
Yet, this graphite electrode development time is also not long, its weak point is that high-temperature oxidation resistance is poor, in use, easy and the airborne oxygen of graphite electrode reacts and consumes in vain, simultaneously, due to graphite electrode in use, normally directly with bolt, overlap copper bar or directly will in copper bar insertion graphite electrode, use, and the useful life of copper bar or copper bar is shorter, easily have influence on reusing of graphite electrode, in a disguised form reduced graphite electrode useful life, caused waste of material.
Utility model content
The technical problem that the utility model solves is to provide a kind of graphite electrode, to solve the shortcoming in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of graphite electrode, comprise graphite electrode body and copper bar, wherein, graphite electrode body is an integrated graphite electrode plate, copper bar is threaded connection part and graphite electrode body is connected, the both sides of described graphite electrode body have groove, in groove, be filled with carbon black filler, and there is one deck individual layer copper coil in carbon black filler mid-game, and the lap position of graphite electrode body and copper bar place is lined with one deck tinfoil paper bed course, and on graphite electrode body except groove and with copper bar lap position surface on form one deck silicon nitride ceramics bed course.
In the utility model, the width of described graphite electrode body is 200-400mm, to improve its utilization rate of electrical, reduces waste of material.
In the utility model, described graphite electrode body is hollow-core construction, can make the surface area of graphite electrode increase, and improves electrode utilance.
In the utility model, the consistency of thickness on the both wings limit of described copper bar, and be as 1/6 ~ 1/5 of graphite electrode body width.
Beneficial effect: the utility model technique is simple, easy to use, the efficiency of heating surface is high, be easy to safeguard, and because graphite electrode body surface applies by ceramic bed course and tinfoil paper as anti oxidation layer, coordinate carbon black filler and copper coil structure can effectively solve the problem that electrode lateral oxidation that in prior art, graphite electrode occurs in smelting process causes graphite electrode loss.
