The cathode pouring fixed carbon slab clamping apparatus of the utility model can make cathode be poured acceptably under the conditions that the phosphorus content of phosphorus pig iron is within 1.2 percent and the pouring temperature of hot-metal is within 1400 DEG C, graphite plates can be recycled to satisfy the need of overhauling electrolysis baths, the product percent of pass is as high as 98 percent, the cost of cathode pouring is reduced owing to the recycling of the graphite plates.
Description
Technical field
A kind of negative electrode cast fixed carbon integrated circuit board tool, what relate to that the cathode carbon pieces used in a kind of Aluminium Electrolysis process and cathode steel bar cast connect usefulness decides the carbon slab jig.
Background technology
In the Aluminium Electrolysis process, cathode carbon pieces that electrolysis is used and cathode steel bar are to adopt the phosphorus pig iron of cast fusion to connect.During operation, the phosphorus pig iron of fusion is poured among the space between cathode carbon pieces and the cathode steel bar, treats after the condensation of the phosphorus pig iron cathode carbon pieces and cathode steel bar fixed and become one.
During operation, need to use graphite cake with the cathode carbon pieces dovetail groove stifled on, between graphite cake and dovetail groove, surround a bottom and sealing all around, above the space of opening, placement cathode steel bar in position in the middle of it.Fix with the jig steel plate at cathode carbon pieces and graphite cake outside, originally employing was carved very tight solid to compress graphite cake between graphite cake and jig steel plate, its shortcoming is: it is loosening that iron is carved because of reasons such as heating and vibrations make in fastening back, cause a large amount of defective negative electrode products, influence the negative electrode casting quality, can not guarantee the needs of overhaul electrolytic cell, and cause graphite cake to break, be out of shape and scrap.
Summary of the invention
Purpose of the present invention is exactly the deficiency that exists at above-mentioned prior art, provides a kind of and can graphite cake is fastening, effectively improve negative electrode casting quality, raising negative electrode product percent of pass, guarantees the negative electrode cast fixed carbon integrated circuit board tool that the overhaul electrolytic cell needs.
The purpose of this utility model is that the following technical scheme in earthing realizes.
A kind of negative electrode cast fixed carbon integrated circuit board tool is characterized in that the structure of this jig comprises:
Fixed support handle-this support shank is one to have the shaft-like support shank of radian, and support shank is connected with between two parties and has the through hole cylindrical fixed body;
Binding thread sleeve pipe-this loop bar is a tapped threaded sleeve that combines as a whole with support shank cylindrical fixed body post through hole;
Precession screw mandrel-this screw mandrel is one to have the externally threaded screw mandrel with binding thread sleeve pipe screw-internal thread fit;
Compressing chassis-this chassis is that a bottom surface is flat board, and the fixing above tubular cylindrical boss of fixing with the termination socket of precession screw mandrel is provided with stopping screw on the boss sidewall;
Precession screw mandrel effort handle-this effort handle is fixed on the precession screw mandrel external end head.
A kind of negative electrode cast fixed carbon integrated circuit board tool of the present utility model, can phosphorus pig iron phosphorus content 1.2% with interior and molten steel pouring temperature 1400 ℃ with interior condition under the negative electrode cast qualified, graphite cake repeatedly uses repeatedly, satisfy the needs of overhaul electrolytic cell, product percent of pass is up to about 98%, graphite cake is repeatedly used, and reduces negative electrode cast cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
A kind of negative electrode cast fixed carbon integrated circuit board tool, the structure of this jig comprises: this support shank of fixed support handle 1-is one to have the shaft-like support shank of radian, and support shank is connected with between two parties and has through hole cylindrical fixed body 2; This loop bar of binding thread sleeve pipe 3-is a tapped threaded sleeve that combines as a whole with support shank cylindrical fixed body post through hole; This screw mandrel of precession screw mandrel 4-is one to have the externally threaded screw mandrel with binding thread sleeve pipe screw-internal thread fit; Compressing this chassis of chassis 5-is that a bottom surface is flat board, and the fixing above tubular cylindrical boss of fixing with the termination socket of precession screw mandrel is provided with stopping screw 6 on the boss sidewall; This effort handle of precession screw mandrel effort handle 7-is fixed on the precession screw mandrel external end head.
During use, on every group of cathode carbon pieces, use fixedly graphite integrated circuit board tool of three groups of novel cathode cast, be stuck in three zones, cathode carbon pieces group upper, middle and lower, the fixed support handle of negative electrode being poured into a mould fixed carbon integrated circuit board tool is stuck in the draw-in groove, rotation precession screw mandrel effort handle, drive the precession screw mandrel, compress the chassis with cathode carbon pieces and graphite cake chucking, make between graphite cake and the cathode carbon pieces closely contact, and guarantee to pour into a mould and all do not produce loosening, slit and graphite cake distortion in the whole process at the cathode carbon pieces group phosphorus pig iron.Show that through trimestral production practices the negative electrode casting quality is greatly improved,, bring up to about 98% by original product percent of pass less than 30%; Not redeformation of graphite cake can repeated multiple times be used.
