Abstract
The utility model relates to a tool special for adding magnesium. The tool is mainly used for producing a copper and magnesium alloy contact line and belongs to the technical field of alloy melting. The tool special for adding magnesium comprises a graphite rod (1); and the head of the graphite rod (1) has a shape of a circular arc which is recessed upward. The tool special for adding magnesium comprises the graphite rod, and the head of the graphite rod has the shape of the circular arc which is recessed upward, so when magnesium is added in a melting process, the head of the tool, which is like an upside-down bowl, can press a magnesium ingot to the bottom of a smelting furnace, the magnesium ingot cannot slip easily in the whole pressing process, copper and magnesium can be mixed fully, and the uniformity and accuracy of copper and magnesium alloy is high.
Description
Technical field
The utility model relates to a kind of magnesium special tool that adds, and is mainly used in the production of copper magnesium alloy contact wire, belongs to the alloy melting technical field.
Background technology
Copper magnesium alloy contact wire is one of key product of high-speed railway of 350 kilometers/hour; The melting of copper-magnesium alloy is crucial technology, because the density of magnesium is less, and the density of copper is bigger; When therefore adding magnesium; Magnesium can float over copper water above, can not make copper magnesium thorough mixing, thereby influence all even tolerance range of copper-magnesium alloy.In order to make copper magnesium thorough mixing, be magnesium to be depressed into the smelting furnace bottom in the past, thereby copper magnesium can be mixed fully through graphite rod, but because the graphite rod head contacts instability with magnesium ingot, slippage easily in the process of pressing magnesium ingot.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, and a kind of magnesium special tool that adds is provided, and can stably magnesium ingot be depressed into the smelting furnace bottom, makes copper magnesium thorough mixing even.
The purpose of the utility model is achieved in that a kind of magnesium special tool that adds, and be characterized in: it comprises graphite rod, and said graphite rod head is arranged to the upwards circular arc of depression.
Compared with prior art, the beneficial effect of the utility model is:
A kind of magnesium special tool that adds of the utility model; It comprises graphite rod, and said graphite rod head is arranged to the upwards circular arc of depression, when in fusion process, adding magnesium; This tool head can be depressed into the smelting furnace bottom with magnesium ingot as the bowl of a back-off; The whole process magnesium ingot that presses down is difficult for slippage, can effectively guarantee copper magnesium thorough mixing, and the uniformity coefficient and the accuracy of final copper-magnesium alloy are higher.
Description of drawings
Fig. 1 is a kind of structural representation that adds the magnesium special tool of the utility model.
Wherein:
Graphite rod 1.
Embodiment
Referring to Fig. 1; The utility model relates to a kind of magnesium special tool that adds, and it comprises graphite rod 1, and said graphite rod 1 head is arranged to the upwards circular arc of depression; When in fusion process, adding magnesium; This tool head can be depressed into smelting furnace bottom with magnesium ingot as the bowl of a back-off, presses down that magnesium ingot is difficult for slippage in the process, thereby makes that copper magnesium thorough mixing is even.
