Embodiment 1
[0024] The invention provides a tin bronze bushing, which is mainly made of the following raw materials in weight percentage: Sn9%, Pb2.5%, Ni0.6%, Zn2%, Si0.3%, Cu balance.
[0025] The preparation method of described tin bronze bushing, it comprises the following steps:
[0026] Step a, copper alloy smelting; the copper alloy smelting is to weigh Sn, Pb, Ni, Si and Cu according to the process ratio and put them into the furnace for heating, and the heating temperature is controlled at 1200 ° C, so that the furnace charge is melted into copper alloy liquid;
[0027] Step b, deoxidation treatment; the deoxidation treatment is to add 0.08% phosphor copper of the total weight of the molten copper alloy liquid in the molten copper alloy liquid obtained in step a, and carry out uniform stirring by injecting nitrogen to implement deoxidation treatment;
[0028] Step c, mold preheating; the mold preheating is to preheat the casting outer mold and the metal core casting inner mold, ...
