Abstract
The utility model relates to equipment for smelting of copper-magnesium alloy, which is mainly applicable to production of copper-magnesium alloy stranded wires or contact wires and belongs to the technical field of electrochemical engineering alloy materials. The equipment comprises a travelling crane (1), cathode copper (3) is hung on a clamping jaw (2) which is hung on a hook of the travelling crane (1), and a magnesium ingot (4) is fixedly arranged inside a lifting lug (5) which is arranged at the bottom of the cathode copper (3). The magnesium ingot of required proportion weight is fixed onto the lifting lug at the bottom of the cathode copper, a combined part of the cathode copper and the magnesium ingot is put into a smelting furnace by the aid of the travelling crane and submerged to the bottom of the smelting furnace by means of gravity of the cathode copper, the whole process is safe and reliable, and splattering and volatilizing are not easy to occur during magnesium smelting. In addition, content of magnesium element can be guaranteed, and error of the content of magnesium element can be controlled within +-0.01%.
Description
Technical field
The utility model relates to a kind of device of melting copper-magnesium alloy, is mainly used in the production of copper-magnesium alloy strand or osculatory, belongs to electrical alloy material technology field.
Background technology
Copper-magnesium alloy is because the alloy strengthening effect, and the electric railway of making is with osculatory, carrier cable and dropper, its good corrosion resistance; Physical strength is far above the fine copper twisted wire, and the current-carrying performance is good, and overload capacity is big; Heat stability is good, high about 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 the high-speed electric railway contact system 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 earlier; And then in smelting furnace, add magnesium ingot; So circulation is successively reinforced to satisfy the production needs of 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; Very easily oxidized, therefore when in smelting furnace, adding magnesium ingot, magnesium ingot is as long as the copper liquid in the contact smelting furnace begins reaction; Can produce splash phenomena, 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 magnesium ingot in addition and replenishes, and causes the magnesium element content homogeneity of final product relatively poor.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency; A kind of device of melting copper-magnesium alloy is provided, and its whole process is safe and reliable, and magnesium is not volatile in fusion process; Magnesium element content can be guaranteed, and the magnesium element content homogeneity of the finished product is better.
The purpose of the utility model is achieved in that a kind of device of melting copper-magnesium alloy; It comprises driving, has mounted jaw on the suspension hook of said driving, is lifted with cathode copper on the said jaw; Said cathode copper bottom is provided with hanger, and the hanger internal fixing is provided with magnesium ingot.
Compared with prior art, the beneficial effect of the utility model is:
The device of a kind of melting copper-magnesium alloy of the utility model, it is fixed in the magnesium ingot of required proportioning weight on the hanger of cathode copper bottom, through driving cathode copper and magnesium ingot conjunction is dropped in the smelting furnace then; Utilize the cathode copper self gravitation to sink to the smelting furnace bottom; Whole process is safe and reliable, and the magnesium melting process is difficult for producing splashes and volatilize, and whole process is safe and reliable; Magnesium element content also can be guaranteed, its magnesium element content error can be controlled at ± 0.01% in.
