Problems solved by technology

[0003] The domestic use is to place red phosphorus in the crucible at one time. When the copper liquid is injected or heated, the mixed reaction effect of gaseous phosphorus and copper is not good. The gaseous phosphorus escapes and is oxidized into phosphorus pentoxide. The phosphorus loss is large and the environment is polluted. , the resulting product is of poor quality, with a phosphorus content of 9%-13%, and a phosphorus absorption rate of only 65%-80%

Abstract

The invention discloses a preparation method of a phosphorus-copper alloy. The preparation method comprises the following steps that electrolytic copper is put into a melting furnace, the melting furnace is powered on, the electrolytic copper is heated and melted, the temperature is raised up to 1160-1180 DEG C, then heating is stopped, melted yellow phosphorus is continuously introduced into a phosphorus-adding pipeline at 15-18 kg / h through a pressure pump, and an inert gas with the pressure of 0.2-0.4 MPa is blown into the melting furnace through an inert gas pipeline, wherein the flow rateis 5-8 NL / min, and the ratio of the total addition amount of the yellow phosphorus to the weight of the electrolytic copper is 1:6; and the yellow phosphorus is vaporized into gaseous phosphorus in the phosphorus-adding pipeline, the gaseous phosphorus is discharged from a phosphorus outlet and is mixed with a copper liquid in an internal-circulating mode, thus a phosphorus-copper alloy liquid isprepared, and then block producing is carried out. According to the preparation method, when smelting is carried out, the phosphorus absorption rate is greatly improved and reaches 95%, and the phosphorus content of final products reaches 15%.

Description

technical field [0001] The present invention relates to a preparation method of phosphorous copper alloy. Background technique [0002] As an excellent deoxidizer, phosphor copper alloy plays a very important role in the field of non-ferrous casting. It can effectively remove oxygen particles in the molten metal and effectively improve the quality and yield of castings; its main production process is electrolytic copper and Red or white phosphorus, synthesized at high temperature. [0003] The domestic use is to put red phosphorus in a crucible at one time. When injecting copper liquid or heating gaseous phosphorus and copper, the mixed reaction effect is not good. The gaseous phosphorus escapes and is oxidized to phosphorus pentoxide, which causes large phosphorus loss and serious environmental pollution. , the quality of the obtained product is poor, the phosphorus content is 9%-13%, and the phosphorus absorption rate is only 65%-80%. SUMMARY OF THE INVENTION [0004] ...
