Description

A kind of shove charge method of the novel graphite stove of high-yield and high-efficiency

Technical field

The present invention relates to the shove charge method of the novel graphite stove of a kind of high-yield and high-efficiency.

Background technology

Graphitizing furnace, has another name called " acheson furnace ", is the key processing equipment of carbon production enterprise acquisition Delanium.Currently, national standard is 8800KWh for producing 1 ton of graphite products power consumption.

Under current market competition environment, for reducing energy consumption, graphitizing furnace develops to string polarization or maximization direction.For producing the enterprise of graphite electrode, it is worthwhile for once producing more graphite electrode.So, acheson furnace just develops into " string pole graphitization " stove.For producing the enterprise of special graphite, due to the molded product that product is " multi-varieties and small-batch ", small-sized extruded product, it is impossible to use " string pole graphitizing furnace ", for reducing production cost, adopt large-scale graphitizing furnace graphitization special graphite made-up article.

And for the carbon element enterprise producing isotropic graphite material, due to the reason of material behavior, it is impossible to use " string pole graphitizing furnace " and " large-scale graphitizing furnace ".Reason is as follows:

1, the graphitization of isotropic graphite made-up article is inadaptable uses " string pole graphitizing furnace "

String pole graphitizing furnace, is after being processed the electrode made-up article end of extrusion, after being well placed successively, compresses burner conductive electrode in burner hydraulic system in stove, makes conductive electrode and product end surface laminating, and promotes product head and the tail successively in stove to be affixed.Afterwards, starting the electric control system of graphitizing furnace, graphitizing furnace power-supply system works, and electric current passes sequentially through made-up article in stove from furnace end electrode, and electric current makes made-up article heating in stove, it is achieved in-furnace temperature, completes the graphitization of graphite electrode made-up article.

String pole graphitizing furnace, is the graphitizing furnace of a kind of efficient fecund, the graphitization energy consumption of the graphitized electrode produced can be made to drop to 4500-5500KWh/ ton, significantly reduce the production cost of graphite electrode.

But string pole graphitizing furnace, owing to current DC is by product, causes that product exists polarity difference in energising direction and non-energized direction.This species diversity, for the graphite electrode state conducted electricity vertically, is advantageous for；But for there being the graphite field of the single crystal growing furnace such as the polycrystalline furnace graphite field of photovoltaic industry, photovoltaic industry and electron trade of specific demand, or the nuclear graphite materials of nuclear reactor core, and incorrect.Because they are required of the isotropism of material.

For produce the molded product that product be " multi-varieties and small-batch ", small-sized extruded product special graphite factory for, for reduce production cost, employing " ultra-large type " graphitizing furnace.

Large-scale graphitizing furnace, is by the conventional graphitizing furnace that furnace core size is 1500mm × 1500mm × 15000mm, increases to 2400mm × 2400mm × 30000mm, make the batch of graphitizing furnace, from 30mt/ stove, bring up to 180mt/ stove.

For the conventional graphitizing furnace that furnace core size is 1500mm × 1500mm × 15000mm, generally do not have bias current.Under normal circumstances, combustion chamber central high temperature district is about higher than high-temperature edge district temperature 200 DEG C.

For large-scale graphitizing furnace, such as the graphitizing furnace that furnace core size is 2400mm × 2400mm × 30000mm, Biased flow phenomenon easily occurs, the temperature in central high temperature district is about higher than high-temperature edge district temperature 450 DEG C, cause that the temperature in high-temperature edge district is too low, the made-up article degree of graphitization in this region is inadequate, have impact on the quality of production of product and sells the scope used.

Detailed description of the invention

In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, and the basic structure of the present invention is only described in a schematic way, and therefore it only shows the composition relevant with the present invention.

1, the operation principle of graphitizing furnace

Producing at full capacity product and resistance material filler and insulation material filler etc. when graphitizing furnace is built-in, whole graphitizing furnace just constitutes one " resistance ".After starting power control system, the power-supply system of graphitizing furnace is started working.

Heat Q in stove, is namely the function of product temperature T in stove

$Q=I^{2}Rt\frac{U^2}{R}t$ Formula 1

T is the time of power-supply system startup work, I be graphitizing furnace stove in electric current, U be graphitizing furnace stove in voltage.

T ∝ Q (product temperature T is directly proportional to the heat Q in stove) formula 2

2, carbon element made-up article change in graphitizing furnace

Along with the prolongation of the power-supply system working time t of graphitizing furnace, the heat Q in stove increases, and in-furnace temperature T raises.Along with the in-furnace temperature of graphitizing furnace rises, in stove, the graphite rate of made-up article rises therewith, and the resistivity of made-up article will decline, and therefore in stove, the resistance of product also declines therewith.Fig. 1 shows the trendgram of the change of carbon element made-up article graphite rate and graphite block resistance variations.

From fig. 1, along with high on in-furnace temperature, in stove, the graphite rate of product improves constantly, and reaches capacity during to 3000 DEG C；In stove, the resistance of product declines with the raising of in-furnace temperature, reaches capacity during to 3000 DEG C.It addition, Fig. 1 shows, graphitizing furnace is respectively arranged with a turning point at 1250 DEG C and 2500 DEG C of regions.

Rt is in the interval of 0 DEG C-1250 DEG C: the change of in-furnace temperature, and the resistance of product and the impact of graphite rate change is little.

Rt is in the interval of 1250 DEG C-2500 DEG C: the change of in-furnace temperature, causes the graphite rate significant change of product in stove, and indefinite form carbon changes into graphite, causes that in stove, the resistance of made-up article sharply changes.

Rt is in the interval of 2500 DEG C-3000 DEG C: the change of in-furnace temperature, causes the micro crystal graphite Stability Analysis of Structures of made-up article in stove, improves the conversion of the graphite rate of made-up article, and in this stage stove, the resistance variations of made-up article significantly reduces.

3, the shove charge method of the novel graphite stove of the high-yield and high-efficiency of the present invention

For the carbon element enterprise producing isotropic graphite material, equally need to reduce the production cost of graphitization process, equally need to improve the production efficiency of graphitization process.According to this, it is necessary to suitably expanding furnace core size, series connection uses graphitizing furnace, solves the technical problems such as bias current.Specific as follows:

1) graphitizing furnace of suitable dimension is designed:

Furnace core size length, width and height are 1800mm × 1800mm × 18000mm, namely from the furnace core size 1500mm × 1500mm × 15000mm of length, suitably expand so that batch brings up to 60mt/ stove from 30mt/ stove.

Usually, the burner stove tail of each graphitizing furnace is respectively arranged with 9 square graphite electrodes, the Commonly Used Size specification of these 9 square graphite electrodes is that 250mm, 300mm, 350mm, 400mm are several, consider the locus that the attended operation etc. of electrode needs, the centre-to-centre spacing of general conductive electrode is 400-600mm, it is so the conductive electrode of 250mm for square graphite electrode size, conductive area is maximum can reach 1500mm × 1500mm, being the conductive electrode of 400mm for square graphite electrode size, conductive area is up to 1800mm × 1800mm.The centre-to-centre spacing of conductive electrode can also be expanded again, but excessive conduction wall deviates easily caused by the electric current in combustion chamber too big, causes that the combustion chamber temperature difference reaches more than 500 DEG C, affects the concordance of product in stove and the machinery of graphitization product and electric property.The roasting base of conventional small dimension graphitization in large-sized graphitizing furnace arises a problem that.

2) series connection uses graphitizing furnace:

By two steps 1) in graphitizing furnace series connection, and be composed in series loop with same power-supply system.The principle that series connection uses is as shown in Figure 2.

Two graphitizing furnaces that series connection uses, total batch G is

G=G1+G1=60mt+60mt=120mt, G1 are the batch of First graphitizing furnace, and G2 is the batch of second graphitizing furnace.

So, the graphitization of 120 tons of products (made-up article) can once be completed, it is possible to decrease the graphitization cost of made-up article.Namely the energy consumption of ton product is reduced to about 4500KWh from 8800KWh.

The bias current problem of so-called graphitizing furnace, it is after the furnace core size expanding graphitizing furnace, owing to graphitization made-up article is " multi items small dimension ", the product of these small dimension sizes, what easily lead in loading furnace process is unbalanced, thus cause the electric current bias current in stove, the series technique problem such as hot-zone displacement and hot-zone deformation, and the made-up article graphitization program differentiation thus caused is big or even some quality problems such as crack due to thermal stress occurs in made-up article.

For producing isotropic special graphite manufacturing enterprise, the specification of every stove graphitization made-up article is limited, and (such as cylindrical product size has φ 700 × 850, φ 750 × 850, φ 900 × 850 equal-specification；Square product includes 1200 × 900 × 300,800 × 800 × 500,850 × 850 × 600 equal-specifications), the specification of these made-up articles is limited, and the method for " product coupling " and " filler coupling " can be adopted to solve bias current problem.

1) product coupling: plan is loaded the made-up article group match in two graphitizing furnaces and made-up article is uniformly put in the combustion chamber length areas of graphitizing furnace.

Made-up article for intending loading in two graphitizing furnaces is grouped, and makes the made-up article state of the art in two graphitizing furnaces of loading (referring to front end production process and the production process of made-up article of the formula of made-up article, made-up article), quantity and weight consistent or basically identical.Plan is made to load the formula of made-up article of 2 stoves, production process, shape, specification and consistent in density or basically identical.Such as: the weight loading the made-up article in two graphitizing furnaces is about about 60 tons, and quantity is also roughly the same；The quantity of the circular quantity of made-up article and the quantity of square made-up article and shaped blank is also basically identical；The dimensions of made-up article is also substantially uniform；For difform made-up article, such as circular, square, shaped blank, respective formula is consistent, and preceding working procedure process is consistent.

Through five aspects such as the formula of made-up article, production process, shape, specification, density are carried out group match, make made-up article in the stove of two graphitizing furnaces of loading basically identical.

Meanwhile, utilize shove charge figure that made-up article is carried out Secondary Match so that the made-up article in each graphitizing furnace is uniformly put in whole combustion chamber length areas, it is to avoid local hot spots suddenlys change, and causes hot-zone Biased flow phenomenon in stove.

Specifically, shove charge figure can obtain by the following method:

Condition: treat the made-up article measurement of shove charge, measure the size of each made-up article, weight and resistance (each made-up article is all numbered, according to number record).

Implement step:

1. the made-up article of shove charge is grouped, is divided into two groups according to overall dimensions size, weight and resistance data, make two groups of data basically identical.

2. the combustion chamber subregion to two graphitizing furnaces, is divided into 6 hot-zones, respectively here

Two set products intending putting into A stove or B stove are carried out second time packet, are put together respectively by the product intending putting into certain hot-zone, be divided into 6 groups by 3. profile and weight-matched.And these data are recorded, their resistivity is filled out respectively in corresponding position, forms the resistance value matrix of each hot-zone.Such as, A1 hot-zone, product three layers, every layer 2 row, often row 3, i.e. 6 every layer, uniformly put totally by 18；Corresponding B1 hot-zone, product is also three layers, and every layer is also 2 rows, and often row 3, i.e. 6 every layer, uniformly put totally by 18.

Their resistor matrix is respectively

$R_{A1}=\left[\begin{array}{cccccc}R11& R12& R13& R14& R15& R16\\ R21& R22& R23& R24& R25& R26\\ R31& R32& R33& R34& R35& R36\end{array}\right]$

$R_{B1}=\left[\begin{array}{cccccc}R{11}^{\′}& R{12}^{\′}& R{13}^{\′}& R{14}^{\′}& R{15}^{\′}& R{16}^{\′}\\ R{21}^{\′}& R{22}^{\′}& R{23}^{\′}& R{24}^{\′}& R{25}^{\′}& R{26}^{\′}\\ R{31}^{\′}& R{32}^{\′}& R{33}^{\′}& R{34}^{\′}& R{35}^{\′}& R{36}^{\′}\end{array}\right]$

Wherein, Rmn and Rmn', m=1～3, n=1～6, represent the resistance value of each product in A1 hot-zone and B1 hot-zone in A stove and B stove respectively.

Respectively obtain R according to this_B2, R_B3, R_B4, R_B5, R_B6；R_A2, R_A3, R_A4, R_A5, R_A6Resistor matrix.

4. calculate the eigenvalue treating shove charge product of each hot-zone, obtain

R_A1, R_A2, R_A3, R_A4, R_A5, R_A6；

R_B1, R_B2, R_B3, R_B4, R_B5, R_B6；

It is respectively compared R_A1With R_B1, R_A2With R_B2, R_A3With R_B3, R_A4With R_B4, R_A5With R_B5, R_A6With R_B6；

If their difference is less than 0.5%, then can shove charge produce according to this.

5. adjust: if their difference is more than 0.5% in 4., then needing to finely tune, each hot-zone data making the product of loading A stove and B stove are basically identical, the error scope less than 0.5%.Such as, R_A1With R_B1Difference reach 1%, then exchange part intend load A stove, B stove product, it is thus achieved that new resistor matrix.

As $R_{A1}=\left[\begin{array}{cccccc}R11& R{12}^{\′}& R13& R14& R15& R16\\ R21& R{22}^{\′}& R23& R24& R25& R26\\ R31& R{32}^{\′}& R33& R34& R35& R36\end{array}\right]$

$R_{B1}=\left[\begin{array}{cccccc}R{11}^{\′}& R12& R{13}^{\′}& R{14}^{\′}& R{15}^{\′}& R{16}^{\′}\\ R{21}^{\′}& R22& R{23}^{\′}& R{24}^{\′}& R{25}^{\′}& R{26}^{\′}\\ R{31}^{\′}& R32& R{33}^{\′}& R{34}^{\′}& R{35}^{\′}& R{36}^{\′}\end{array}\right]$

Calculate R_A1、R_B1Eigenvalue, until be fine-tuning to R_A1≈R_B1Till.

Above R_AnAnd R_Bn, n=1～6, the respectively resistance value of 6 hot-zones in A stove and B stove.

2) filler coupling: graphitizing furnace filler includes resistance material and insulation material two kinds, is wherein mainly the coupling of resistance material.

The coupling of resistance material, refer to that plan inserts step 2) in two graphitizing furnaces in the physical and chemical index of resistance material consistent or basically identical, as basically identical in its granularity, source (manufacturer), cooking level etc. so that their resistance is basically identical.

As for insulation material, also make a strong impact.For stopping its impact on made-up article graphitizing process, also need to mate.The coupling of insulation material requires just the same with the made-up article of resistance material, namely intend inserting step 2) in two graphitizing furnaces in the physical and chemical index of insulation material consistent or basically identical, as basically identical in its granularity, source (manufacturer), cooking level etc..

By to product coupling and filler coupling, solving the bias current technical problem of the graphitizing furnace expanding furnace core size.

3) temperature of the graphitizing furnace of two series connection is synchronized.

As in figure 2 it is shown, two graphitizing furnace series connection, then the caloric value of whole system is

Q=I²Rt,R₁For the resistance of First graphitizing furnace, R₂Being the resistance of second graphitizing furnace, t is the time of power-supply system startup work, I be graphitizing furnace stove in electric current, U be graphitizing furnace stove in voltage.

Q=Q₁+Q₂, Q₁For the heat of First graphitizing furnace, Q₂It it is the heat of second graphitizing furnace.

$Q_1=I^2{R}_{1}T={\left(\frac{U}{R_1+R_2}\right)}^2{R}_{1}t,$

$Q_2=I^2{R}_{2}T={\left(\frac{U}{R_1+R_2}\right)}^2{R}_{2}t$

Due to R₁≈R₂, then Q₁≈Q₂。

Due to the resistance of made-up article in the stove of two graphitizing furnaces, change with the variations in temperature in stove, see Fig. 1.For this, different phase adopt diverse ways be controlled:

Rt in the interval of 0 DEG C-1250 DEG C, the change of in-furnace temperature, the resistance of made-up article and the impact of graphite rate is little.So now being controlled according to the furnace temperature of the graphitizing furnace of lower temperature in two measured graphitizing furnaces, the temperature of an other graphitizing furnace is as monitoring data.

Rt is in the interval of 1250 DEG C-2500 DEG C, and the change of in-furnace temperature, graphite rate and Resistance Influence to made-up article are huge.Now need dynamically to observe control.In principle according to the temperature of the graphitizing furnace of lower temperature for controlling temperature, the temperature of another one graphitizing furnace is for monitoring temperature.Such as: interval at this, the resistance of original state First graphitizing furnace is less than the resistance of second graphitizing furnace, i.e. R₁< R₂, Q occurs₁< Q₂, namely the temperature of First graphitizing furnace is lower than the temperature of second graphitizing furnace.

In the stove of second graphitizing furnace, made-up article graphite rate improves, and resistance declines, and causes the resistance resistance less than First graphitizing furnace of second graphitizing furnace, i.e. R₁> R₂.So slowly occur in that Q₁> Q₂Phenomenon, cause in the stove of First graphitizing furnace made-up article degree of graphitization to improve, cause the resistance phenomenon lower than the resistance of First graphitizing furnace of second graphitizing furnace.

On the whole, for the graphitizing furnace of series connection, it may appear that First graphitizing furnace and second graphitizing furnace are in the phenomenon of the furnace temperature alternate in this interval.No matter how furnace temperature changes, all using the temperature of the graphitizing furnace of relatively low temperature as controlling temperature, the temperature of another one graphitizing furnace is as monitoring temperature.

Rt in the interval of 2500 DEG C-3000 DEG C, the change of in-furnace temperature, the impact of the graphite rate of made-up article in stove and the impact of resistance variations is little.Now still with the temperature of the relatively low graphitizing furnace of temperature for controlling temperature, the temperature of an other graphitizing furnace is for monitoring temperature, to guarantee that in the stove of two graphitizing furnaces, product is attained by the temperature of 2850 DEG C or even 3000 DEG C.

Two graphitizing furnace series connection are used, and suitably expand the furnace core size of graphitizing furnace, thus reduce the graphitization energy consumption of made-up article by the shove charge method of the novel graphite stove of the high-yield and high-efficiency of the present invention, and the energy consumption of ton product is reduced to about 4500KWh；The made-up article and filler intending loading graphitizing furnace is mated, solves the technical problems such as the bias current after being expanded by furnace core size；The graphitizing furnace of two series connection is carried out temperature synchronization, thus solving the temperature contrast that two graphitizing furnace initial resistance differences cause.

With the above-mentioned desirable embodiment according to the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not necessarily departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content in description, it is necessary to determine its technical scope according to right.
