Abstract

PURPOSE:To obtain a formed graphite which can be vertically connected extremely advantageously, by applying continuous T-shaped ridge or invertly T-shaped groove having linearly varying width to the connecting end of the graphite along the direction of inclination. CONSTITUTION:When the top end of the formed graphite 1 and the bottom end of the formed graphite 4 are horizontal planes, these formed graphite articles are connected with each other without using a third member, and when the top end of the formed graphite 1 has same structure as the top end of the formed graphite 4, these articles are for continuous connection use. The connecting end faces 2, 5 are planes inclined at same inclination to the horizontal plane. The top of the T-shaped ridge is a plane having the same inclination. The ridge is attached to the nearly central part of the connecting end face 5 and has tapered width. More preferably, the ridge is a ribbon having a width widening from the bottom to the top of the connecting end face along the direction of inclination. The ridge is provided with a taper widening from the base at the connecting end face to the upper end.

This relates to graphite molded bodies for connection used in cases.

られている。Conventionally, in the operation of various electrolytic cells, electric furnaces, etc., new graphite molded bodies are connected vertically to the graphite electrodes used as they wear out due to use, without interrupting operation. Otherwise, operations are continued after a very short interruption, and for this reason, the connection method for graphite molded bodies is the screw-in method using threaded cables,
A bolt type joining method, an adhesive joining method, and the like are known.

可く簡単なものが望まれている。However, since the graphite molded body has a considerable weight, the connection of such a graphite molded body requires sufficient strength at the connection part, and since smooth flow of current is desirable, it is necessary to connect as much as possible at the joint part. In addition to requiring perfect adhesion, it is also desired that the connection be simple and easy to operate.

いる。Among the conventional methods mentioned above, the screw-in method using a threaded nipple is the most widely used method to satisfy these requirements in a relatively balanced manner. In order to improve this, it is necessary to perform high-precision thread cutting on both the nipple and the graphite molded body, and even though the processing load is currently quite high, the product must be extremely expensive. , there is a considerable workload in terms of connection operations. Further, the bar-type joining method and the adhesive method each have problems in terms of adhesion and connection strength, and are considered to be applicable only in some special cases.

見出して本発明に到達した。The inventors of the present invention have made extensive studies to solve the problems of the conventional method, and as a result, the connection end surface of the graphite molded body is inclined with respect to the horizontal plane, and the slope of the connection end surface is at the center of the graphite body. A T-shaped protrusion that is strip-shaped in the direction along the , that is, a strip-shaped protrusion that has a flat upper end, a narrow base, and expands toward the upper end (its cross section is an inverted trapezoid), and A protrusion whose width changes linearly in the length direction of the strip and also in the direction along the slope of the connecting end face of the tab is provided, and the connecting end face of the other graphite molded body that is in contact with this graphite molded body is By providing an inverted T-shaped recess that fits into the strip, sufficient strength and extremely high degree of adhesion can be obtained at the connection part, and the connection will always remain tight without loosening even if an accidental lateral force is applied to the connection part. It is extremely easy to process protrusions and grooves, which have the advantage of having a force that improves the strength, compared to thread cutting or bolt type, and the connection operation is also simple. Therefore, the present invention was achieved by discovering that it is possible to realize an innovative connection method that is extremely industrially advantageous.

。Hereinafter, the present invention will be described in detail with reference to the drawings.The graphite molded body of the present invention is a graphite molded body most typically used as a graphite electrode, although its use is not particularly limited. It is most typically used by connecting one piece after another in the vertical direction.

いる。Figure 2 is a top view of the graphite molded body (A) and a front view.
(b) and side view -t-). As is clear from this, the connecting end surface 5 is inclined with respect to the horizontal plane, and the T-shaped protrusion 6 is provided in a strip shape at the center of the connecting end surface in the direction of inclination of the connecting end surface, and its width is in the direction of the inclination. It has a longitudinal taper that expands from bottom to top, and in this case, the upper end of the protrusion is a plane having the same slope as the connection end surface 5, and the top edge of the protrusion is a plane with the same slope as the connection end surface 5. It has a tapered side surface that widens from the root g toward the upper end 7.

It has a longitudinal taper that widens from the bottom to the top of the direction, and the bottom surface of the drip remover is a similarly inclined plane, and the taper extends from the top on the connecting end surface of the drip remover to the bottom surface. It has an expanding lateral taper.

度的には有利な場合もあり得る。In addition, when the horizontal cross section of the graphite molded body has directionality, such as an ellipse or a rectangle, it is generally desirable that the inclination direction of the connecting end surface and the longitudinal direction of the T-shaped protrusion extend along the longitudinal direction of the horizontal cross section. If the diameter in the lateral direction of the horizontal section is extremely small, it may be more advantageous in terms of strength to provide it in the lateral direction.

合が解けないという利益も得られることとなる。In addition, when the horizontal cross section of the graphite molded body is square or rectangular, the direction of inclination of the connecting end surface is typically selected to be a direction that spans the center of two opposing sides, but in some cases It is also permissible to select diagonally. Therefore, the direction of inclination of the connection end surface is determined in each specific case, taking into account the shape of the horizontal cross section of the graphite molded body, the weight of the graphite molded body, the ease of creating protrusions and drip removal, and the ease of connection work. You can choose the most suitable one. This inclination on the connecting end surface, together with the protrusions and the slopes in the length direction and side surface of the drip, ensures that when the graphite molded bodies are connected vertically, the degree of adhesion of the connected part will always and naturally be higher. This also provides the advantage that the fitting is not easily unraveled even by accidental forces in the lateral direction.

最小幅が２以上程度となる様な高さを選定すれば良い。Hereinafter, only the T-shaped protrusion will be described in detail, but since the inverted T-shaped dripping fits into the T-shaped protrusion, it will be easily understood in exactly the same way. The height, width, and taper in the length direction of the T-shaped protrusion and the taper on the sides should be such that when one of the two connected graphite molded bodies is supported and the other is suspended in the air, the other will not fall. Various designs are possible depending on the shape of the connecting end surface, as long as sufficient fitting is maintained and strength is maintained to prevent breakage, etc., by either the protrusion or drip removal.
Generally, the width is in the range of 1 to 1, more preferably η to the minor axis of the connecting end surface at the center point of the height and length of the protrusion, and the taper of the side surface is 4' and S-' with respect to the horizontal plane. ~g
? ', more preferably selected from the angle range of bo0 to g5°. In addition, the height of the protrusion can be selected in various ways depending on the shape of the entire graphite molded body and its connecting end face, so it cannot be determined unconditionally, but it is determined by the taper of the side surface and the width of the center point as described above, as well as the length direction as described below. The height may be selected such that the taper requirements are met, the maximum width at the top is 2 or less with respect to the minor axis of the connecting end face, and the minimum width at the base is approximately 2 or more.

る大型品であることから一層増幅される。Next, the taper in the length direction of the T-shaped protrusion is provided mainly to enable the protrusion and the drip to fit together with an extremely high degree of closeness, and to facilitate the fitting operation. In other words, graphite molded bodies are required to have high adhesion at the connection part, and to meet this requirement, the protrusions and vibration isolation must be precisely formed, but the protrusions and vibration isolation do not have a taper in the longitudinal direction. In this case, the more precise the machining, the more difficult the alignment during fitting becomes, and if the alignment is made easier, the degree of adhesion of the connection will be reduced. This difficulty is further amplified by the fact that graphite compacts are generally large products with considerable weight.

される結果、より有利である。However, if the protrusion and the seismic isolation have a longitudinal taper as in the present invention, it is easy to insert the minimum width end of the protrusion into the maximum width end of the seismic isolation, and then all you have to do is slide one side. It is very easy to fit and connect even products with the highest processing precision, and on the other hand, even if the processing precision is not particularly high, sufficient adhesion of the fitting portion can be ensured. However, the specific numerical value of the taper in the longitudinal direction of the lever varies depending on the length of the ridge, so it cannot be expressed in terms of angle, but when the ends are first fitted, for example, the maximum width end of the seismic isolation The minimum width should be such that it can be directly fitted from the shipboard direction at least to the leading edge, and preferably it should be fitted directly from above and below at the Z-Z position in the length direction of the ridge or seismic isolation. If this is possible, the fitting operation will be more advantageous as the sliding operation will be reduced.

よう。Note that although the taper of the side surface of the protrusion is necessary on both sides, the taper in the length direction may be made only on one side, which may be preferable in some cases since it makes the work of forming and fitting the protrusion easier.

すべきである。When connecting the graphite molded bodies of the present invention, T
If a graphite molded body with an inverted T-shape vibration isolation is connected to a graphite molded body with mold protrusions on the connecting end surface of the lower end, the graphite molded body below will be separated and pieces will fall until just before it is exhausted. This is preferable because it can be used up while preventing this as much as possible. In that case, the weight support after connection is usually carried out by the connected upper graphite molded body, so the width of the protrusion and vibration isolation should be designed so that it increases in the upward direction of the slope of the connection end surface. be.

The same applies to the case where the molded bodies in the uppermost tier are suspended, in which case the uppermost molded body is prevented from sliding off the molded body in the second tier until it is next supported. It is desirable to hold it using an appropriate fastener.

。For some reason, for example, if the weight is supported by the bottom molded body contrary to the above, or even if the support method is the same as above, it is better to fit the T-shaped protrusion at the lower end to the inverted T-shaped seismic isolation at the upper end. In convenient cases, the width of the protrusion and vibration isolation can be expanded in the downward direction of the slope of the connection end surface, contrary to the above, and in that case, when changing the height of the protrusion, etc., it is natural to However, the design should be such that the height increases in the direction of width expansion (the width of the height increases, not the absolute position of the height).

ば良い。In addition, if support is provided by the connected lower graphite molded body, and there is a case where an inverted T-shaped seismic isolation at the upper end and a T-shaped protrusion at the lower end are connected, the direction in which the width of the protrusion and the seismic isolation increases is It is easily understood that is the upward direction of the inclination of the connection end surface. In any case, the design should be such that the fitting becomes tighter in the direction in which the graphite molded body tends to slide due to the inclination of the connecting end surface.

があっても容易には嵌合が解けることがない。As detailed above, the graphite molded bodies of the present invention are typically connected one after another as they wear out, as is known in graphite electrodes. Although the work and connection operations are extremely simple, the degree of adhesion between the connected graphite molded bodies is extremely high, and the strength of the connection part is also ensured, which is a great advantage. be. In particular, due to the slope of the connection end surface, the connection part is always subjected to force in the direction of tighter contact, so even if the connection part is accidentally subjected to a lateral force that loosens the connection, it will not be easy to connect the connection part. It can't be solved.

が導電性であればなお好ましい。Note that some additional effects can be obtained by using an adhesive when connecting the graphite molded bodies of the present invention. In other words, even if a lateral force that loosens the fit between the protrusion and the droplet is generated by chance, the fit will not come loose, and compared to the case where the weight is held only by the fit between the protrusion and the droplet. This greatly removes restrictions on strength,
(Therefore, when adhesives are used together, the various requirements necessary to maintain strength, such as the width of the protrusions, etc., may not necessarily be important conditions.)
Φ#-#ψ#0-#Furthermore, the degree of adhesion between the two connected graphite molded bodies is completely guaranteed, and the current flows more smoothly between the connecting surfaces. It is even more preferable if the adhesive used in this sense is electrically conductive.
