Abstract
A technology for making Cu-P anode features that the insulating furnace and melting furnace are designed to be linked and heated by the power current, the liquid in melting furnace is introduced to insulating furnace via ciphon channel, the Cu-P anode is directly formed by lifting up the liquid from insulating furnace, the P content and level of the molten liquid in melting furnace are measured on-line, and the amounts of Cu and additive to be added are automatically controlled. Its advantages are continuous production, easy control, high quality of product and simplified process.
Description
The present invention relates to metallurgical chemistry and electronic industrial technology field, belong to the production technology of electro-coppering (Cu-P anode) especially.
Fast development along with electronic industry, printed circuit board (PCB) develops into omnifarious multilayer circuit printing plate by simple single sided board, be widely used in departments such as electronics, communication, space flight, specification of quality to printed circuit board (PCB) is more and more higher simultaneously, thereby also more and more higher to the specification of quality of the used main raw Cu-P anode of printed circuit board (PCB), produce the supreme pursuit that colory Cu-P anode becomes the sector.The production method of present state-of-the-art Cu-P anode is the horizontal casting method of the U.S., this method adopts the middle frequency furnace heating, hand-fed, the fusing back adds modified batching, regularly measure melt temperature in the stove, after solution in the stove reaches the specification of quality of regulation, pour copper liquid into tundish and forward in the holding furnace again and be incubated, the copper mouth of a river by holding furnace becomes the Cu-P anode work in-process with copper phosphorus liquation through the crystallizer founding then, slightly is refined into Cu-P anode by following operation again.
The horizontal casting method is produced for being interrupted, and equipment is simple, and single stove quality product is easy to control.Its shortcoming is that level of automation is not high, temperature can not continuously measured and indication, the influence of operational quality human factor is big, the copper mouth of a river leakiness copper of holding furnace, bleedout usually appears, the consumption of additive is also big, and the quality of each stove solution is difficult to control to unanimity, thereby makes the quality instability of bulk article.
Below said Cu-P anode be meant without accurately machined Cu-P anode work in-process.
The objective of the invention is to design a kind of method of serialization production of copper P anode, begin from feeding intake to the generation Cu-P anode, full-automation, temperature, modified batching on-line Control overcome artifical influence factor in the stove, guarantee that the bulk article quality is even, qualified.
The present invention realizes like this, the present invention is the improvement of horizontal casting method, the heating of employing main frequency furnace, holding furnace and process furnace are connected as a single entity, raw copper is joined smelting furnace, furnace charge oxide compound after the fusing and trace impurity come-up, fine copper flows in the holding furnace by siphon passage, the phosphorus content of the copper liquid in the smelting furnace is by conducting electricity fast and level gauging instrument METHOD FOR CONTINUOUS DETERMINATION, the quick data of conduction and the level gauging instrument material amount controller of directly providing and delivering, the dosage controller is regulated raw copper and additive add-on automatically by specified value.The temperature of holding furnace is come automatic homothermic by thermostat, and qualified copper phosphorus liquation is upwards pulled out from the holding furnace liquid level through crystallizer, generates Cu-P anode.
The present invention adopts serialization production, and holding furnace and smelting furnace are conjuncted, have cancelled tundish, directly pull out Cu-P anode from holding furnace, has avoided the copper mouth of a river of holding furnace to leak copper and bleedout phenomenon.Chemical Composition and the temperature online METHOD FOR CONTINUOUS DETERMINATION and the control of melt in the stove are produced and are stablized, and produce quality-guarantee in batches.Simplify simultaneously production process greatly, saved the labor force.
The contrast accompanying drawing further specifies the present invention below.
1-smelting furnace in the accompanying drawing, 2-raw copper batching scale, 3-batching controller, 4-additive formulations claim, 5-fast conduction and level gauging instrument, 6-siphon passage, 7-holding furnace, 8-temperature measuring controller, 9-crystallizer, 10-commentaries on classics rod, 11-tractor, 12-slag removing hole, 13-shears.
Smelting furnace (1) and holding furnace (7) are designed to the disjunctor main frequency furnace, the partition wall place designs a siphon passage (6), the temperature of smelting furnace (1) and holding furnace (7) is by temperature measuring controller (8) control automatically, raw copper joins the smelting furnace (1) from raw copper batching scale (2), phosphor-included additive claims (4) to join the smelting furnace (1) from additive formulations, raw copper and additive be fusing fast in smelting furnace (1), oxide compound and trace impurity float and remove from slag removing hole (12), phosphorous copper liquation in the smelting furnace (1) is with conducting electricity fast and level gauging instrument (5) on-line determination, the data that quick conduction and level gauging instrument (5) record are sent into batching controller (3), batching controller (3) is analyzed and is calculated by preset parameters and adjusts the flow that raw copper batching scale (2) and additive formulations claim (4), measurement and batching are finished automatically, and the Chemical Composition that guarantees interior liquid level of stove and solution is in qualified controlling valu scope.Qualified phosphorous copper liquid flows into holding furnace (7) by siphon passage (6), with crystallizer (9) Cu-P anode is upwards drawn and be solidified into to the phosphorous copper liquid in the holding furnace (7).Last priming power is provided through changeing rod (10) by tractor (11).
When tractor (11) is constantly pulled out Cu-P anode from holding furnace, liquid level in the holding furnace (7) descends, syphonic effect takes place in siphon passage (6) simultaneously, draws fluid holding furnace (7) with smelting furnace (1), the liquid level of smelting furnace (1) descends, conduction and level gauging instrument (5) pass to batching controller (3) with liquid level signal fast, batching controller (3) control raw copper batching scale (2) and additive formulations claim (4) reinforced in proportion simultaneously, when the liquid level in the smelting furnace (1) arrives appointed positions, conduction and level gauging instrument (5) pass to batching controller (3) with signal fast, and batching controller (3) control raw copper batching scale (2) and additive formulations claim (4) to stop simultaneously feeding in raw material.
Production period, the temperature of smelting furnace (1) and holding furnace (7) is adjusted within the controlling valu scope automatically by temperature measuring controller (8).
Example with accompanying drawing 2 comes the present invention is further explained below:
Design a disjunctor audio frequency stove, smelting furnace (1) and holding furnace (7) fuse, the centre separates with a partition wall, design one siphon passage (6) between the partition wall, the temperature of smelting furnace (1) and holding furnace (7) is controlled automatically with temperature measuring controller (8), and this stove adopts power 2 * 75kW, designed productive capacity is for producing 2000 tons of Cu-P anodes per year, process control parameter: furnace temperature 1190-1230 ℃, melt electric conductivity 58-72%IACS, product phosphorus content 0.04-0.065%.
