Abstract
A protective hoop of anode metal claw used in aluminum electrolyzing consists of a protective hoop of anode metal claw (1) bonded of two half-circle carbon bodies (1) by adhesive. The spigots (2) of the contact faces of the two half-circle carbon hoops are step-shaped and the two spigots (2) of the two half-circle carbon hoops complement each other. The utility model is characterized in that the steps are obtuse steps and that the bottoms of the protective hoops (3) are provided with chamfers (4).
Description
Technical field: the utility model belongs to the electrolgtic aluminium anode steel claw protection ring.
Background technology: in the Aluminum Electrolysis Production process, anode connects carbon dioxide process carbon electrode 7 by steel pawl 6 and constitutes.Because the continuous loss of carbon dioxide process carbon electrode 7, ionogen 8 washes away steel pawl 6 easily, steel pawl 6 is caused etch, not only influenced the steel pawl life-span, and owing to the existence of iron in the aluminium causes the aluminium quality to reduce, for this reason, in process of production, usually add a carbon protective ring 3 in the anode steel jaw bottom, it is to be bonded together into the garden ring-type by two and half garden shape carbon bodies to wrap in steel pawl bottom, because the butt joint end face of two halves garden shape carbon body is generally the plane, bond area is little, degree of adhesion is poor, and dislocation easily, for overcoming this shortcoming, utility model patent " aluminium anode steel claw protection ring " application number 02207062.1 proposes to change the butt joint end face of general guard ring two halves garden shape carbon body into stepped appearance by planar shaped, further stepped appearance is changed into concavo-convex snapping shape, to be that the plane is caused bonding little with area though this has solved end face, bonding fastness is poor, the shortcoming of easy dislocation, but blemish in an otherwise perfect thing is that two halves garden homoannular right angle ladder and concavo-convex fastening position stress are too concentrated, thereby ruptures easily at guard ring ladder and fastening position; In addition in long-term electrolytic aluminum process; steel pawl bottom casting ferrophosphorus 8 can form overlap 5, and overlap makes carbon protective ring can not directly wrap steel pawl foot attached to around the steel pawl bottom; if will make the plain guard ring bag of phosphorus to steel pawl foot, this is very bothersome must to reject overlap.
Summary of the invention: the purpose of this utility model is to overcome utility model patent " aluminium anode steel claw protection ring "; the deficiency of application number 02207062.1 design; its design is done further to improve; it is bonding firmly to propose a kind of energy; protection interface easy fracture not, the electrolgtic aluminium anode steel claw protection ring that not influenced by the overlap of steel pawl bottom casting ferrophosphorus.
For achieving the above object; this reality has the butt joint end face seam of two and half garden shape carbon bodies of novel steel claw protection ring; though be stepped appearance; but the angle between ladder is not right angle but obtuse angle; the obtuse angle ladder butt joint end face seam of two and half garden shape carbon bodies cooperatively interacts complementary; in the bottom of guard ring one chamfering is arranged, when two and half garden shape carbon bodies are bonded together when forming guard ring and wrapping in steel pawl bottom the influence of the ferrophosphorus overlap of not cast.
The utility model result of use has not only prolonged the work-ing life of guard ring; and in installation process; can cause the damage of steel claw protection ring hardly; when steel claw protection ring is installed; even steel pawl lower periphery has the burr of casting ferrophosphorus, do not need to reject, because a chamfering is arranged at the bottom of guard ring yet; installation rate has been accelerated in can avoid the casting influence of burr of ferrophosphorus greatly.
Description of drawings: Fig. 1, steel claw protection ring mated condition front view; Fig. 2, steel claw protection ring mated condition front view A-A section; Fig. 3, steel claw protection ring two and half garden shape carbon body front views; Fig. 4, steel claw protection ring user mode reference drawing.
Among the figure: 1. half garden shape carbon body, 2. half garden shape carbon body butt joint end face is suitable for reading, 3. steel claw protection ring, 4. guard ring bottom chamfer, 5. overlap, 6. steel pawl, 7. electrolytic aluminium anode carbon dioxide process carbon electrode, 8. casting ferrophosphorus.
Embodiment: the utility model electrolgtic aluminium anode steel claw protection ring (abbreviation steel claw protection ring) is bonded together into garden ring-type steel claw protection ring 3 (Fig. 1) by two and half garden shape carbon bodies 1 (Fig. 3) through tackiness agent; the end face seam 2 of half garden shape carbon body 1 is stepped appearance; two halves garden carbon body end face seam cooperatively interacts and is complementary; it is characterized in that this species stage ladder in obtuse angle; the weak link that does not have stress concentration; thereby make steel claw protection ring end face otch not fragile; there is chamfering 4 lower end of steel claw protection ring; with steel claw protection ring 3 with the A-A face cut open Fig. 2; can know from Fig. 2 and to see chamfering 4; the size of chamfering 4 and shape can be adjusted according to the shape and the size of the overlap 5 of steel pawl lower end casting ferrophosphorus; can be that straight line also can be curve or camber line; when the overlap 5 of casting ferrophosphorus 8 appears in steel pawl 6 lower ends; the protection of steel pawl is installed does not need the row deburring; the chamfering 4 of steel claw protection ring can make steel claw protection ring 3 avoid overlap 5, makes the easy for installation rapid of steel claw protection ring and reliable in quality.
Of the present utility model installing and using with reference to figure 4; with the utility model steel claw protection ring two and half garden shape carbon bodies; butt joint is enclosed within on the steel pawl 6; with the bonding half garden shape carbon body butt joint end face seam of caking agent; form steel claw protection ring 3; the overlap 5 of casting ferrophosphorus 8 is arranged at steel pawl 6 bottoms; because chamfering 4 is arranged at the steel claw protection ring bottom, has avoided the influence of overlap 5, the shape size on chamfering 4 limits changes with the shape and the size variation of overlap; it can be straight line; curve or camber line, steel pawl 6 connects electrolytic aluminium anode carbon dioxide process carbon electrode 7, because the protection of steel claw protection ring 3; after 7 losses of electrolytic aluminium anode carbon dioxide process carbon electrode, steel pawl 6 is not subjected to the electrolytical etch of electrolgtic aluminium.The tackiness agent coal tar commonly used and the coke fusion of bonding half garden shape carbon body butt joint end face seam form.
Claims (2)
1. electrolgtic aluminium anode steel claw protection ring; by two and half garden shape carbon bodies (1) through the bonding steel claw protection ring (3) that forms of tackiness agent; half garden shape carbon element ring butt joint end face seam (2) is stepped; two halves garden carbon body end face seam (2) complementation; it is characterized in that this species stage ladder in obtuse angle, chamfering (4) is arranged at the bottom of guard ring (3).
2. electrolgtic aluminium anode steel claw protection ring according to claim 1, the bottom chamfer (4) that it is characterized in that guard ring (3) is straight line or curve or camber line.
