Abstract

The invention discloses a deoxidizing method for copper and copper alloy smelting and belongs to deoxidizing methods. The deoxidizing method comprises the following steps: stirring: after copper is completely molten, using an iron rod to fully stir the molten copper and adjusting the ventilation condition of the molten copper; bottom blowing by nitrogen: when stirring, beginning to introduce high-pressure nitrogen into the molten copper to enable the molten copper to be uniform and the nitrogen pressure to be 0.6 MPa; sampling: after stirring, sampling the molten copper to test the oxygen content; continuing keeping the nitrogen pressure at 0.6 MPa; and casting after bottom blowing for 10 minutes. Compared with the prior art, the deoxidizing method for copper and copper alloy smelting is simple, efficient, quick and accurate to dioxide, improves the production efficiency, and reduces the production cost, so that the method has good promotion and application values.

Description

A kind of copper and smelting copper alloy deoxidation method
Technical field
The present invention relates to a kind of deoxidation method, especially a kind of copper and smelting copper alloy deoxidation method.
Background technology
Copper and copper alloy are widely used in the production and manufacturing of electronics, electrician, electrical part because it has good conduction, heat conductivility.Control to the oxygen level in the copper in copper and copper alloy manufacturing processed has very strict regulation.Each large copper processing enterprise is all in research in the whole nation for the control method of oxygen level, and method also is various, but imperfection is gone back in the control of oxygen level in the copper liquid.At present, good solution is not also arranged.
Summary of the invention
Technical assignment of the present invention is to provide a kind of copper and smelting copper alloy deoxidation method for above-mentioned deficiency of the prior art, this copper and smelting copper alloy deoxidation method have simply, efficient, quick, accurate deaerating effect, enhance productivity, reduced the characteristics such as production cost.
The technical solution adopted for the present invention to solve the technical problems is:
Copper provided by the invention and smelting copper alloy deoxidation method, it comprises following operation steps:
(1) stirs: after copper liquid melts fully, fully stir with iron staff, regulate the ventilative situation of copper liquid;
(2) nitrogen bottom blowing: in the time of stirring, begin to lead to high pressure nitrogen in copper liquid and make it evenly, nitrogen pressure is 0.6MPa;
(3) sampling: stir complete after, the sampling and testing oxygen level;
(4) continuing to keep nitrogen pressure is 0.60.6MPa, and bottom blowing began casting in 10 minutes;
The deoxidation method above-mentioned according to right is characterized in that, high pressure nitrogen is filled with in the smelting furnace bottom, and the bottom is provided with ventilating pit, uses the gas permeable brick closed bottom.
A kind of copper of the present invention and smelting copper alloy deoxidation method are compared with existing technology, has following outstanding beneficial effect: use a kind of copper of the present invention and smelting copper alloy deoxidation method, has simple, efficient, quick, accurate deaerating effect, enhance productivity, reduced the characteristics such as production cost.
Embodiment
Explain to a kind of copper of the present invention and below the smelting copper alloy deoxidation method work.
A kind of copper of the present invention and smelting copper alloy deoxidation method, it comprises following operation steps:
(1) stirs: after copper liquid melts fully, fully stir with iron staff, regulate the ventilative situation of copper liquid;
(2) nitrogen bottom blowing: in the time of stirring, begin to lead to high pressure nitrogen in copper liquid and make it evenly, nitrogen pressure is 0.6MPa;
(3) sampling: stir complete after, the sampling and testing oxygen level;
(4) continuing to keep nitrogen pressure is 0.60.6MPa, and bottom blowing began casting in 10 minutes;
It is characterized in that high pressure nitrogen is filled with in the smelting furnace bottom, the bottom is provided with ventilating pit, uses the gas permeable brick closed bottom.
Through technician's Exploration and Research, think and carry out the nitrogen bottom blowing can be to copper and smelting copper alloy the time, because of the cheap of nitrogen copper liquid is had no adverse effect simultaneously, Gu as source of the gas.This method is carried out test of many times at our factory, has found optimum controling method.At present, in production practice, apply.
Except the described technical characterictic of specification sheets, be the known technology of those skilled in the art.
