Description
Technical field
The production unit that the utility model relates to copper products draws the auxiliary facility of smelting furnace, be specifically related to a kind of on draw the graphite protective sleeve of smelting furnace channel.
Background technology
Railway contact line conducting wire and the blank required for carrier cable twisted wire, what select is all Copper and its alloy product, in the middle of producing, up-drawing method is the state-of-the-art production technique of one of copper series product, the processing of copper products is relatively special, so the technique of producing copper products, and equipment has special requirement, the temperature of fusion of copper is about 1083 DEG C, the temperature that refining is drawn is between 1145 DEG C ~ 1162 DEG C, the starting material cathode plate used in whole production process, from the state at normal temperature to the high-temperature copper liquid about 1150 smelting furnace DEG C, this control process is abnormally dangerous careful.Therefore also very high to the requirement of smelting furnace, draw smelting furnace on whole and be divided into three melting processes, fusing storehouse, stabilizing bin and thermal insulation barn, the channel of a heat conduction is had in each storehouse, the whole melting process of stove is all rely on electric energy heating channel to melt copper coin and insulation, the principle of its work is, electric current is by the mounted Ω shape red copper smelting-ring in advance when building brickwork, after power supply, electric energy produces powerful low-tension current, pre-buried channel melts by the heat energy produced under the effect of electric current, then transfer heat on the copper starting material in stove and form eddy current, carry out continuous print fusing having been drawn whole continuous up-casting process.On draw smelting furnace in process of production; channel be wherein whole on draw the most important heating system of smelting furnace; it bear fusing, heat conduction, eddy current, transition, insulation whole on be introduced through process control; protective sleeve protect channel fusing of heating, sinter molding and on derivation produce, be vital to the protection of channel in production.The furnace charge of whole brickwork is all tiny dust granules and refractory brick, and all brickwork material all can be suppressed integral through pneumatic pick, then in the process heated gradually, slowly become solid.In the process that this develops, channel has fatal danger to rupture exactly; the fracture of channel just means that this smelting furnace is scrapped; the loss caused is huge; therefore in brickwork, blow-on, heat, in the process that heats up and when furnace charge changes along with the change of temperature, great impact all produced on channel; but channel is also the main source heated to the copper body of outside; there is its heating could allow furnace charge sinter molding, so be inevitable to the protection of channel.
Original channel directly contacts with furnace charge when brickwork, channel heat fusing process in channel can be out of shape by the sintering of furnace charge, thus shorten life-span of stove.In the middle of the production of routine, because the metallic element of furnace charge can participate in the middle of the copper liquid of fusing under the effect of high temperature, cause the product electrical property of firm blow-on and mechanical property quality to decline, defective production rate is higher.Furnace charge is burnt till solid in the process of sintering under the effect of high temperature, the face of being close to of channel can distortion in various degree, surface irregularity is uneven, this can cause a lot of troubles in the middle of the production in later stage, what railway contact line conducting wire 98% adopted is the product of copper alloy, MAGNESIUM METAL is exactly the wherein one that alloying constituent needs to add, magnesium can produce chemical transformation in the copper liquid of high temperature, impel the viscosity of copper liquid to increase resistance to increase, a kind of product of the most bad control relatively in fusion process, if now have distortion around channel, the bad phenomenon such as coarse occurs, along with continuous alloyed copper liquid is through channel, the transition wall of channel can be left over the alloy junction crystal of magnesium and copper, the thermal energy transfer that will increase channel is on the increase along with xln, increase the defatigation of channel when heating operation, increase thereupon be exactly fusing time produce powerful eddy current, this eddy current can produce gravitation and vibration, this gravitation and vibration are exactly the fatal killer of channel, channel is caused to rupture, whole stove is also just scrapped.In the production process in this stage, the yield rate of the copper bar of above drawing will reduce, and qualification rate reduces, and production cost will increase greatly.One platform draws smelting furnace and have several channel at the same time in work simultaneously, if there is one of them to block, this stove just declaration is scrapped.Therefore the life-span of channel is exactly the life-span of whole platform drawing smelting furnace.
Utility model content
In order to overcome the deficiency in background technology, the purpose of this utility model provide a kind of on draw the graphite protective sleeve of smelting furnace channel.
The utility model adopts following technical scheme for completing above-mentioned purpose:
On draw the graphite protective sleeve of smelting furnace channel, described graphite protective sleeve is arranged between channel and furnace charge; The bottom shape of described graphite protective sleeve and the shape kissing of channel are joined; The outer of the outer edge surface formation graphite protective sleeve protruding upward of described graphite protective sleeve bottom surface; Described graphite protective sleeve has channel heater wire collar aperture, and described channel heater wire collar aperture is corresponding with the channel heater wire collar aperture on channel; The periphery formation annular edge protruding upward of described channel heater wire collar aperture; Described outer, between annular edge and bottom surface, form the channel standing groove placing channel; Cast on draw smelting furnace time, channel is placed in the channel standing groove of graphite protective sleeve, upper draw smelting furnace built blow-on heat time, the thermal source of channel can conduct heat to the furnace charge of surrounding by graphite protective sleeve gradually, slowly by the furnace charge sinter molding of surrounding.
The utility model proposes a kind of on draw the graphite protective sleeve of smelting furnace channel; be arranged on the outside of channel; when channel fusing sintering furnace charge; owing to there being the protection of graphite protective sleeve, make the smooth surface of channel, its deformation rate is very low; protect channel efficiently when melting sintering; the generation of the bad phenomenon such as the thicker resistance in channel surface is large, improves the production capacity of drawing smelting furnace, extends the work-ing life of drawing smelting furnace.
