Summary of the invention:
The objective of the invention is to overcome above-mentioned deficiency, phosphorus content height in a kind of alloy is provided, foreign matter content is low, the preparation method of composition isostatic P-Cu mother alloy between stove and stove.
The object of the present invention is achieved like this: a kind of preparation method of P-Cu mother alloy is characterized in that: phosphorus content 14.5～15% in the alloy material, and copper content 84.499～84.999%, its preparation method comprise following processing step:
In phosphorus melting device, heating also keeps 70 ℃～80 ℃ of phosphorus liquid temps with solid yellow phosphorus for step 1, molten phosphorus;
Step 2, pressure phosphorus feed phosphorus liquid in the phosphorus melting device and press the phosphorus device, press the interior inflated with nitrogen of phosphorus device also to keep 50 ℃～60 ℃ of phosphorus liquid temps;
Step 3, defeated phosphorus will be pressed the defeated phosphorus device of phosphorus liquid feeding in the phosphorus device;
Step 4, melting place electrolytic copper in the smelting furnace, and heating also keeps 1150～1200 ℃ of furnace temperature, and charcoal layer is covered on copper liquid surface in the smelting furnace, and copper liquid is isolated with oxygen all the time, will fail the phosphorus device and directly stretch in the copper liquid, and phosphorus liquid and copper liquid are mixed and made into phosphorus-copper alloy liquid;
Phosphorus-copper alloy liquid is come out of the stove in step 5, clamp dog or granulation, pours ready mould into, fills nitrogen in the mould, is cast into block P-Cu mother alloy; Or phosphorus-copper alloy liquid come out of the stove, open the granulation mould in hole through the bottom and pour granulating in the granulation pond into, inject water in the granulation pond, fill nitrogen, water temperature is controlled at 20～25 ℃, and it is dark that water level is controlled at 6/8～7/8 pond, drags for grain, makes granular P-Cu mother alloy.
Press phosphorus explained hereafter P-Cu mother alloy because the present invention adopts, flue dust is little during melting, and phosphorus content height in the alloy reaches 14.5～15%, and is higher by 1.5～2% than common P-Cu mother alloy; Foreign matter content is low: plumbous＜0.001%, iron＜0.02%, nickel＜0.001%, tin＜0.001%, zinc＜0.001%; Composition difference is little between stove and stove, and alloy ingredient is even, constant product quality.Every impurity index all reaches industry standard.
