Description
Technical field
The present invention relates to a kind of method of smelting copper magnesium alloy, be mainly used in the production of copper-magnesium alloy strand or osculatory, belong to electrical alloy material technology field.
Background technology
Copper-magnesium alloy is because the alloy strengthening effect, Prospect of Contact Wire Materials for Electrical Railway, carrier cable and the dropper made, its good corrosion resistance, physical strength is far above pure copper stranded wire, the current-carrying performance is good, overload capacity is large, Heat stability is good, high approximately 1.5 times of its single line strength ratio fine copper single line intensity, can live through load impact, working stability is reliable, and therefore long service life is widely used in Highspeed Catenary and uses as current-carrying alloyed contact line and carrier cable.
During in the past copper-magnesium alloy melting, in smelting furnace, add a cathode copper first, and then in smelting furnace, add magnesium ingot, so circulation is successively reinforced to satisfy the need of production of big-length copper-magnesium alloy blank, and added magnesium ingot weight calculates according to copper-magnesium alloy proportioning and standard cathode weight of copper.But because magnesium is a kind of very active metal; its fusing point, boiling point are lower, and density is low, and is very easily oxidized; therefore when in smelting furnace, adding magnesium ingot; magnesium ingot can produce splash phenomena as long as the copper liquid in the contact smelting furnace begins reaction, and its security is relatively poor; and magnesium is easy to volatilization; the Mg content of final copper-magnesium alloy is often on the low side, needs to add in addition magnesium ingot and replenishes, and causes the magnesium element content homogeneity of final product relatively poor.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, a kind of method of smelting copper magnesium alloy is provided, its whole process safety is reliable, and magnesium is not volatile in fusion process, and magnesium element content can be guaranteed, and the magnesium element content homogeneity of the finished product is better.
The object of the present invention is achieved like this: a kind of method of smelting copper magnesium alloy, and it comprises following processing step:
Step 1: calculate the every magnesium ingot weight that standard cathode copper is required according to the copper-magnesium alloy proportioning;
Step 2: the magnesium ingot that will calculate required weight is filled in the hanger of cathode copper bottom, and the compression hanger is fixed formation cathode copper and magnesium ingot conjunction;
Step 3: cathode copper and magnesium ingot conjunction are lifted, drop in the smelting furnace, utilize the own wt of cathode copper to make conjunction sink to rapidly the smelting furnace bottom;
Step 4: be heated to 1050 ~ 1200 ℃ during melting, cathode copper and magnesium ingot conjunction are smelted into the copper-magnesium alloy liquation, every certain interval of time adds a cathode copper and magnesium ingot conjunction, and so circulation realizes producing continuously.
Compared with prior art, the invention has the beneficial effects as follows:
The method of a kind of smelting copper magnesium alloy of the present invention, it is fixed in the magnesium ingot of required proportioning weight on the hanger of cathode copper bottom, then cathode copper is added in the smelting furnace with magnesium ingot, magnesium ingot can sink to the smelting furnace bottom, then by the electric convection effect in the smelting furnace copper magnesium elements is mixed in smelting furnace, and difficult generation of magnesium melting process splashed and volatilized, whole process safety is reliable, magnesium element content also can be guaranteed, its magnesium element content error can be controlled at ± 0.01% in.
