Abstract
The present invention relates to a kind of pure copper smelting technique.It is characterized in that technological process includes:A, graphite crucible is preheated to kermesinus, the drying charcoal or coverture for adding a layer thickness to be 30 50mm at crucible bottom, sequentially adds leftover pieces, useless block and bar, be eventually adding fine copper;B, the alloying element added can be placed on the table of medium-frequency induction furnace and preheat, frequent movable furnace charge in whole melting process, to prevent putting up a bridge;C, after heating makes alloying element all melt, when temperature reaches 1,200 1220 DEG C, the phosphor-copper deoxidation for accounting for alloy liquid quality 0.3 0.4% is added, fully removes and skims after reaction.The present invention is simple to operate, and technical process is easily controllable, and obtained copper purity is high, and plasticity is strong.
Description
Technical field
The present invention relates to a kind of pure copper smelting technique.
Background technology
Casting is one kind important in non-ferrous metal with fine copper and copper alloy, with wider in actual production.Either
Sand casting or model casting, melting are all a vital rings in Foundry Production.
The content of the invention
For problems of the prior art, it is an object of the invention to provide a kind of technical side of pure copper smelting technique
Case.
Described a kind of pure copper smelting technique, it is characterised in that technological process includes:
A, graphite crucible is preheated to kermesinus, drying charcoal or coverture that a layer thickness is 30-50mm is added at crucible bottom, then
Leftover pieces, useless block and bar are sequentially added, is eventually adding fine copper;
B, the alloying element added can be placed on the table of medium-frequency induction furnace and preheat, frequent travelling oven in whole melting process
Material, to prevent putting up a bridge;
C, after heating makes alloying element all melt, when temperature reaches 1200-1220 DEG C, addition accounts for alloy liquid quality 0.3-
Remove and skim after 0.4% phosphor-copper deoxidation, fully reaction.
Pure copper smelting technique provided by the invention, its advantage is, simple to operate, and technical process is easy to control
System, obtained copper purity is high, and plasticity is strong.
