Abstract
A process for preparing the P-Cu alloy used as anode material includes smelting the electrolytic copper in the smelting furnace under reduction condition, loading the molten copper in the temp-holding furnace, adding intermediate P-Cu alloy whose P content is 13-15%, and casting. Its advantages are loss of P, low cost, easy control to temp, and high quality of castings.
Description
Technical field
The present invention relates to be used for the working method of galvanized anodic phosphorous copper alloy.
Background technology
Anodic phosphorous copper is a kind of phosphorous copper base binary alloy material of 0.035-0.065% that is, with ball, grain or tabularly be widely used in industrial circles such as printed circuit board, five metals, decoration as the galvanic anode material.At present, the working method of anodic phosphorous copper alloy is that raw material drops into the medium-frequency induction furnace fusing in proportion with electrolytic copper and phosphorous phosphor bronze alloy at 13-15% mainly, in go to that horizontal casting is reprocessed into needed shape in the crucible type holding furnace.Because in intermediate frequency furnace, in the turn of tidal stream process and all can cause the loss of phosphorus in the insulation castingprocesses, particularly copper water contacts with air in turn of tidal stream and insulation castingprocesses, thereby the loss of phosphorus is bigger, make the consumption of phosphor bronze alloy strengthen, not only can cause the increasing of production cost, and the phosphorus content instability in the product, being difficult to operation control, the quality product fluctuation is big.
Summary of the invention
To be solved by this invention is that above-mentioned anodic phosphorous copper alloy causes the high and quality problem of unstable of production cost greatly owing to phosphorus loses in the course of processing.
Method of the present invention is: electrolytic copper is dropped into be fused into copper liquid in the smelting furnace under reductive condition; Above-mentioned copper liquid is sent in the holding furnace under the reducing gas protection, and the temperature in the holding furnace is controlled at 1145-1155 ℃, and the bath surface of holding furnace covers reductive agent; In above-mentioned holding furnace, add the phosphor bronze alloy of phosphorus content at 13-15%; Through casting, obtain desired product.Because phosphor bronze alloy directly adds in the holding furnace, making does not have the loss of phosphorus in fusing of copper liquid and the turn of tidal stream process, so the loss of phosphorus is less, not only can reduce production costs, and also can reduce the span of control of phosphorus amount, makes the fluctuation of phosphorus little, constant product quality.
For copper phosphorus melt is evenly distributed, holding furnace adopts main frequency furnace, by electromagnetic force melt in the stove is carried out induction stirring in insulating process.
For the ease of copper liquid turn of tidal stream, smelting furnace adopts main frequency furnace.
In order to make anodic phosphorous copper alloy organizing compact structure, phosphoric is evenly distributed, and updraft continuous casting process is adopted in casting.
Because the adding of the fusing of electrolytic copper and phosphor bronze alloy is carried out in two stoves respectively among the present invention, there is not the loss of phosphorus in fusing and the turn of tidal stream process, and there is reductive agent to cover in the holding furnace melt and air are completely cut off, can not cause a large amount of losses of phosphorus, not only reduced production cost, and the add-on of phosphor bronze alloy can be according to the copper liquid measure accurate calculation that adds to holding furnace at every turn, makes in the product fluctuation of phosphorus content little, constant product quality; The fusing of copper and phosphorating is separately carried out in two stoves, can control suitable smelting temperature and casting temp easily and improve casting quality.
Embodiment
Smelting furnace of the present invention and holding furnace all adopt main frequency furnace, between smelting furnace and the holding furnace chute are arranged; The bath surface of smelting furnace covers wooden carbon, and chute is with extraneous sealing and have pipeline to communicate with coal gas, and there is the continuous up-casting machine holding furnace top.Copper content is that 99.99% electrolytic copper is fused into copper liquid and the temperature of copper liquid is controlled at 1165-1175 ℃ in smelting furnace, and copper liquid flows in the holding furnace by chute, and the temperature in the holding furnace is controlled at 1145-1155 ℃, and the bath surface of holding furnace covers graphite; Phosphorus content is added by the charging opening above the holding furnace at the phosphor bronze alloy of 13-15%.In castingprocesses, when the liquid level of holding furnace drops to certain position, in stove, drop into the phosphor bronze alloy particle earlier, again smelting furnace is tilted, copper liquid is flowed in the holding furnace through chute, the liquid level in holding furnace is raised to till the position of setting.In smelting furnace and chute, feed the coal gas protection in the process of toppling over.Phosphorating earlier in holding furnace afterwards adds copper liquid, and the process that copper liquid is toppled over also is the whipping process to holding furnace, and phosphorus is evenly distributed in holding furnace.Each add-on of phosphor bronze alloy can be calculated according to the each copper liquid of holding furnace magnitude of recruitment, as once additional copper liquid heavily is 100kg, the phosphorus content of target alloy is 0.05%, the phosphorus content of used phosphor bronze alloy is 13%, and then the add-on of phosphor bronze alloy should be: 100kg*0.05%/13%=3.84kg.In order to prevent phosphorus scaling loss in holding furnace, reduce the phosphorus content in the target alloy, each actual add-on of phosphor bronze alloy adds for the 103%-110% that calculates the gained add-on as stated above.
