Abstract
The present invention relates to a method for manufacturing a suspension bar for a permanent cathode used in the electrolysis of metals, wherein the suspension bar is formed of a rigid metal outer jacket and a highly conductive core attached inside it. By means of this connection, a tight contact is achieved between the outer jacket and the core and this connection is made by drawing, upsetting, melting or casting.
Description
The manufacture method of the hanger rod that durable negative electrode is used when the present invention relates to a kind of electrolytic metal, wherein hanger rod is a rigid metal overcoat, inboard affix high conductivity core body.In this way, between overcoat and core body, can realize good connection.This connection can obtain with drawing, upsetting, fusion or casting technique.
Traditional method is with the beginning pole plate when electrolytic metal, and it is to form as far back as the surface growth of motherboard.When pole plate was made negative electrode with the beginning, it and the metal that is deposited should be commaterials, copper for example, and this method is abandoned, when especially considering new input.When newly-built potroom, generally tend to use durable negative electrode and its plate-shaped member usually to make of duriron or titanium.
Durable negative electrode can be distinguished the structure and plate-shaped member the fixing with respect to hanger rod that are cathode suspension bar substantially with multiple diverse ways manufacturing.The additional of the structure of hanger rod and plate-shaped member is inconvenient, and its problem is on hanger rod enough copper will be arranged for big electric current is imported plate-shaped member.Because duriron is a poor conductor, can not be it uniquely as excellent material.
Have in the prior art several method can be when making the hanger rod of durable negative electrode with solve copper and other metals in conjunction with problem.On industry, there are two kinds of structures dominant.First kind of hanger rod that uses full copper is again with a kind of special alloy welding wire weldering lastblock duriron plate member.One of shortcoming of this method is the flexibility of the hanger rod that becomes with whole copper, and the result makes this rod easily deformable, is particularly useful for cathode weight when big.The temperature rise that causes because of short circuit makes this problem more become to worsening.
Two of the shortcoming of this full copper hanger rod is: be difficult to make discrete suspension ring enough firmly to be additional to hanger rod, because according to the requirement of material processing technology, suspension ring are positioned at the hanger rod top.Three of its shortcoming is that the particular alloy between duriron plate member and the copper hanger rod is welded on the anti-corrosion this point and other positions of negative electrode are not quite identical.The advantage of this structure is that the making of this durable negative electrode is fast, drops into low and processing site is not had particular requirement.Other advantages are that the basal area of copper is big in hanger rod, cause in existing this durable cathode construction resistance little, and energy consumption is low.
In second kind of widely used durable cathode suspension bar structure, piped hanger rod core body is with stainless or acidproof steel.The duriron plate member is soldered on these materials with solid wire.After having welded, on hanger rod and the plate-shaped member topmost weld seam again metallide copper have enough electric conductivitys so that make.Copper facing also is in order to prevent that weld seam is subjected to the influence of environment.This method for example sees English Patent 2,040,311.
The significant disadvantages of aforesaid method is a metallide length consuming time, several days time, and output increases greatly and drop into also big on electroplating device man-hour.Electroplate and also to require production line must be positioned at the place of close potroom.In this structure, the basal area of copper is littler than above-mentioned full copper hanger rod.Its resistance of durable negative electrode of now stating this structure is slightly increased, thereupon also big than with full copper hanger rod of its energy consumption.On the other hand, the wearing quality of steel core hanger rod is good.Therefore, though negative electrode very heavy it can not be out of shape yet, also can not be short-circuited makes the life-span of negative electrode be a problem.It is also easier to be connected on this structure above-mentioned discrete suspension ring.Suspension ring are to be welded to securely before plating on the stainless steel core body of this rod, thereby make this sound construction and durable.In the design, all weld seams are all forming between the part under stainless steel and the copper facing, thereby make this structure not only firmly but also durable.
United States Patent (USP) 4,647,358 have described another kind of durable negative electrode, and wherein, the hanger rod topmost is made with steel pipe, and it welds mutually with plate-shaped member.In the hanger rod steel duct hollow copper tubing is arranged, it can be longer than steel pipe, also can open the part, end of steel pipe so that the interior copper pipe that makes electric current pass through hanger rod flows.The steel band difference in internal diameters seldom is exactly that the external diameter of copper pipe is so that closely connect each other.The manufacture method of outer tube, according to patent, axially be at first get through so that interior pipe is loaded into, in packing into, behind the pipe, again outer tube and interior pipe are welded vertically mutually, the interior pipe of hanger rod welds in the end of rod each other mutually with outer tube.
The advantage of aforesaid method be the intensity height of hanger rod and negative plate parts and independently suspension ring can be soldered directly to the outer tube position of making of same metal.But its shortcoming is: weld separately and/or hide from view between outer tube and core body in order to realize suitable contact need.The result is difficult to keep the consistence of excellent quality when producing in enormous quantities.Other shortcoming is that also outer tube and core body are welded together in the end, makes that this structure is airtight and do not expose to be corroded, because any electrolysate between outer tube and the core body all is bad to the long-term durability of rod.And the numerous processing step of product makes it be difficult to realize automatization, so that cost rises, and people have noticed that also overwhelming is the consistence that will ensure the quality of products.
The present invention pays close attention to the manufacture method of the used durable cathode suspension bar of electrolytic metal, and its hanger rod is made with a rigid metal outer tube, puts into the high conductivity core body with the method for drawing, forging, melt or cast in the inside.The purpose of these technology is without any realize enough good electrical connection and soundness under the additional process steps between outer tube and core body.Most preferably be between each parts of rod, to realize metallurgical binding.Thereby, after outer tube and core body are connected, as long as outer tube at least at one end partly opening just can between cathode suspension bar and electrolysis cell busbar, form good electric interlock.Its essential characteristic is with clear and definite in relevant patent claim.
This paper mainly with copper as high conductivity core body metal, but also available aluminium.The most handy refining steel of rigid metal outer tube is made, and is acidproof or stainless steel.
When hanger rod was made of drawing process, bar-shaped high conductivity core body was by the copper drawing of preparing in outer tube is in advance formed.If when outer tube was made with refining steel, the easiest method was that it is carried out in advance, because of refining steel is difficult to drawing.Be made of copper the most preferably with the corresponding tubular parison of outer tube internal diameter.This blank is put in the steel sleeve pipe, and in cold drawing bench, an axle is carried out drawing by in the copper blank aperture, makes copper be attached to the surface of steel sleeve pipe tightly.The aperture that rod iron also can be used as the axle drawing or compresses into the copper base also be stayed it in the rod that has been shaped if desired.Adding man-hour, if necessary, also can supported to prevent its distortion from the outside to the steel sleeve pipe.Combining and to influence by regulating processing temperature between the shaping of copper and it and the steel.
Durable cathode suspension bar also can be made with upsetting technology, can put into outer tube to a suitable core body in view of the above and be pressurizeed so that it can closely push outer tube in significant points such as ends at least in its end.Adjust the shaping of the favourable copper of processing temperature, in drawing.Mix up use temperature and can between outer tube and core body, form metallurgical, bond with drawing or upsetting technology.
Hanger rod also can make with smelting process, earlier one with casting, be drawn into copper core pattern base that complete processing obtains with the solid-state steel sleeve pipe of putting into, heat outer tube then and the core body parison makes its fusion.Fusion can be carried out in the vertical position, and preferably block the steel pipe low side this moment.Steel pipe while this moment supporting-core build base also comprises fused copper in outer tube.Outer tube still fully remains on solid-state when thermal treatment.Between steel and the copper engage that usable temp and time are regulated and copper is in molten state, just can obtain metallurgical, bond with suitable combination.
When making hanger rod with casting technique, do mold to the steel sleeve pipe, directly within it the copper core body is cast out.But outer tube will fully remain on solid state.Prevent contingent bonding between copper and copper outer tube surface, can use for example also available other coating methods of graphite solution-treated.By casting fused copper in solid-state steel sleeve pipe, can between steel and copper, form reliable metallurgical, bond.
Casting technique itself for example can be a casting fused core body metal in the vertical steel pipe of a low side sealing.It will additionally heat whole rod (outer tube ten core bodys) with high-power preheating steel sleeve pipe or after molten metal has been cast earlier.Outer tube is remained valid in the time at sufficiently long with the molten copper metal to be contacted so that go to form metallurgical binding if having time between outer tube and core body.If outer tube not preheating in advance, the heating when casting or after the casting of perhaps whole rod will not have fracture and taking place, but the core body metal outside the cold inwall fast setting of telescopic then can't form joint.
Another method of filling in metal jacket pipe is exactly to immerse outer tube in the molten metal copper with the sufficiently long time, and preheating this moment can be unnecessary fully.Submergence can be under the horizontality at pipe to be carried out, and in advance steel sleeve pipe two ends is blocked before immersion and will be opened abundant hole so that inject copper and excluding air at the upside of pipe.The quantity in hole for example is advisable to open one at an end of pipe.Pipe also can remain on obliquity with in guaranteeing that molten metal can be seated in.Immersion is also desirable vertical certainly, and only block the low side of steel sleeve pipe this moment before submergence.For example, submergence just enough obtained satisfactory result in about one minute.
As above disclosed, between durable negative electrode and electrolysis cell busbar, wish the metallic contact of satisfactory electrical conductivity to occur so that the current loss between them is little.For example availablely just can achieve the goal easily such as drawing, upsetting, fusion or casting core body, after each parts of rod are all connected, can be one side taking-up of steel sleeve from the both ends or one end of rod, the end face that leaves the copper core body has suitable length.The section of the copper of rod contact simultaneously also can form by desired shape, for example arc-shaped curved surface.
Directly be welded in as required with the discrete suspension ring of refining steel on the steel sleeve pipe of hanger rod.Equally, the negative electrode plate-shaped member also is to be soldered directly on the steel sleeve, and plate member and suspension ring can or append on the steel sleeve pipe before the copper core body is additional afterwards, and weld seam usually forms in using with a kind of metal solder, so not only weldering but also durable easily.
