Abstract
The invention discloses a method for preparing a phosphor-copper alloy rod. The phosphor-copper alloy rod with phosphor content of 400-650 PPM and oxygen content of 10-50 PPM is produced by continuous melting, alloying, heat-preserving and storing, continuous casting and continuous press-rolling. The invention provides the method capable of continuously preparing the phosphor-copper alloy rod from raw material taking as well as alloy adding to copper alloy rod forming without stop through a plurality of processing equipment processes, so that energy can be saved, cost is reduced, mass production is improved, and raw material cost can be reduced for the printed circuit board industry and the power industry.
Description
Technical field
The method that the present invention relates to prepare phosphor copper bar, particularly to a kind of phosphor-copper bar (line) for producing printed circuit board (PCB) and metal plating be forged into phosphorous copper balls, clipping becomes the preparation method of the consistent continuous way of phosphor-copper block.
Background technology
Certain some phosphor copper bar production method, relates to alloying element mixed proportion and alloy crystalline solid structural differences because of have, limit be intended to ask can production in a large number, if Gonna breakthrough this limit, further relate to the practical problem that demand is little, therefore rareness be to research and development in this respect.
Inventor notices that traditionally fine copper bar has the production method of a kind of continuous casting and rolling.The stock size that the method is produced is at 8 millimeters of fine copper bars; and oxygen content is between 100-650PPM; oxygen content would generally be controlled upper and lower at 350PPM; the fine copper bar so produced becomes tiny line footpath to be typically only capable to meet as the copper cash needed for general electric wire through wire drawing; and to be used in the material required in terms of low oxygen content, can be inappropriate.At present producing the equipment of fine copper bar with south electric wire company of the U.S. (Southwire CO.USA) with this, the general Lopez company (PROPERZI S.P.A.Italy) of Italy is main. but do not develop to make alloyed copper bar.
In these years electroplate demand as anodic phosphorous copper due to the copper of printed circuit board (PCB) (PCB) with metal, plastics----a kind of phosphorous copper alloy, demand is the biggest.The present inventor is engaged in related industry accumulation many years of experience, and then a kind of new method producing copper alloy bar of this invention of research and development.

2) in feed arrangement, phosphor-copper raw mixture enters the feeding device of calciner, calciner includes column stove, reacting furnace or electromagnetic induction furnace, calciner makes in-furnace temperature between 1150 DEG C-1300 DEG C by the gas of burning high heat, phosphor-copper raw mixture is fused into phosphorus-copper alloy liquid, phosphor copper liquid temp is between 1150 DEG C-1260 DEG C, and the oxygen content in phosphorus-copper alloy liquid is between 10-50ppm；
3) phosphorus-copper alloy liquid flows to insulation storing furnace by chute, adds P-Cu mother alloy or red phosphorus while flowing to insulation storing furnace in chute or insulation storing furnace, makes in insulation storing furnace in phosphorus-copper alloy liquid the content of phosphorus between 400-650ppm；
4) by burning high heat gas in insulation storing furnace, making holding insulation storing furnace cavity temperature between 1150 DEG C-1260 DEG C, insulation storing furnace pours out copper liquid continuously, enters continuous casting equipment, making phosphorus-copper alloy liquid become phosphor copper embryo, phosphor copper embryo temperature is between 300 DEG C-900 DEG C；
5) after phosphor copper embryo enters continuous rolling press via excision comer device, then becoming phosphor copper bar through continuous pressure rolling phosphor copper embryo, described phosphor copper shank diameter is 15-50mm.
The described method preparing phosphor copper bar, it is characterised in that described continuous casting equipment selects single steel band type or double steel band type continuous casting equipment.
The described method preparing phosphor copper bar, it is characterised in that after described phosphor copper embryo enters continuous rolling press via excision comer device, then become phosphor copper line, phosphor copper ball or phosphor copper block through continuous pressure rolling phosphor copper embryo.
The method have the advantages that the saving energy, reduce cost, and improve a large amount of production, can be to printed circuit board (PCB) and electroplating industry, it is provided that reduce effect of cost of material.
