Description

Technical Field

[0001] The invention relates to the technical field of continuous casting and rolling equipment, in particular to a three-body vacuum down-drawing continuous casting and rolling equipment. Background Art

[0002] The preparation of ultrafine copper and copper alloy wires requires high-quality parent materials. Domestic ultrafine wires generally refer to copper or copper alloy wires with a diameter of less than 0.05mm, with a high wire breakage rate. For example, it is difficult to reduce the diameter of a copper alloy containing 2% silver to less than 0.05mm, and the resistance is unstable, reflecting the biggest problem of unstable composition. The emergence of these problems is directly related to material purity, alloy uniformity, organizational uniformity, surface treatment, etc.

[0014] Preferably, a spray cooling mechanism is provided between the rolling mill and the coiler, and the spray cooling mechanism consists of a water pump, a water tank, a plate exchanger, a spray head and a pipeline.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The three-body vacuum down-drawing continuous casting and rolling equipment is provided with a melting furnace, a holding furnace and a casting furnace. When the alloy liquid in the melting furnace enters the holding furnace, it is stirred by an electromagnetic stirrer to make the internal alloy liquid uniform. The composition of the alloy liquid is detected by a sensor inside the holding furnace, and metal blocks are added to the holding furnace through a side feeding port on the holding furnace to be melted and stirred as needed, so as to achieve fine adjustment of the alloy liquid inside the holding furnace. Similarly, the sensor inside the casting furnace can further detect the composition of the alloy liquid provided by the holding furnace, and metal blocks can also be added to the casting furnace through a side feeding port on the casting furnace to melt and stir as needed, so as to achieve further fine adjustment of the alloy liquid inside the casting furnace. By adopting the composition of the melting furnace for rough adjustment, the holding furnace for fine adjustment, and the casting furnace for fine adjustment, the stability of the composition is guaranteed, and the influence of impurities in the raw materials that are not completely melted during the continuous feeding process on the composition of the alloy liquid when the traditional single furnace is working is avoided.

[0016] 2. The three-body vacuum down-drawing continuous casting and rolling equipment is provided with a smelting furnace for melting alloys and removing gases and individual impurities. The smelting furnace is not provided with a casting function, but is used as a storage unit for alloy melting and liquid alloy to quickly melt the alloy and make a rough composition adjustment. The sensor can be effectively used to detect the temperature and liquid level in the furnace body. When the liquid level of the insulation furnace below drops to a certain level, the valve on the first pipeline is opened, and the alloy liquid in the smelting furnace automatically flows to the insulation furnace. When the liquid level of the insulation furnace reaches a certain height, the valve on the first pipeline is automatically closed, and the alloy liquid can be continuously supplied to the insulation furnace. The insulation furnace keeps the metal liquid in the required temperature range and can continuously provide the metal liquid for the casting furnace. The constant liquid level of the casting furnace ensures the stability of the casting structure, and the constant temperature and constant pressure metal liquid is sent to the crystallizer, so that the whole system works continuously to increase the production capacity, and avoids the situation that the head and tail of the ingot of the ordinary casting furnace have different pressures during casting, and the density and continuity of the structure change.

[0017] 3. The three-body vacuum down-drawing continuous casting and rolling equipment is convenient for installing hydraulic telescopic columns by arranging driving components and fixing plates. The hydraulic telescopic columns can effectively lift up the upper cover. When the hydraulic telescopic columns lift up the upper cover, the driving motor works to effectively drive the driving shaft and the driving wheel to rotate. Under the transmission action of the synchronous belt, the driven wheel and the rotating column can be driven to rotate synchronously, so that the rotating column drives the hydraulic telescopic columns and the top plate to rotate, and the top plate drives the upper cover to rotate and move away, which is convenient for putting alloy raw materials into the smelting furnace, saving time and effort.

When the liquid level of the insulation furnace 3 below drops to a certain level, the valve 10 on the first pipeline 4 is opened, and the alloy liquid in the smelting furnace 2 automatically flows to the insulation furnace 3. When the liquid level of the insulation furnace 3 reaches a certain height, the valve 10 on the first pipeline 4 is automatically closed, and the alloy liquid can be continuously supplied to the insulation furnace 3. The insulation furnace 3 keeps the metal liquid within the required temperature range and can continuously provide the metal liquid to the casting furnace 5. Then, the casting furnace 5 maintains a constant temperature and feeds the constant temperature and constant pressure metal liquid into the crystallizer, so that the whole system works continuously to increase production capacity, and avoids the situation that the head and tail of the ordinary casting furnace ingot have different pressures during casting, and the density and continuity of the organization change.

[0031] Furthermore, when the alloy liquid in the smelting furnace 2 enters the holding furnace 3, it is stirred by an electromagnetic stirrer to make the internal alloy liquid homogenized, and the composition of the alloy liquid is detected by the sensor inside the holding furnace 3, and metal blocks are added to the holding furnace 3 through the side feeding port on the holding furnace 3 as needed, melted and continued to be stirred, so as to achieve fine-tuning of the alloy liquid inside the holding furnace 3. Similarly, the sensor inside the casting furnace 5 can further detect the composition of the alloy liquid provided by the holding furnace 3, and metal blocks can also be added to the casting furnace 5 through the side feeding port on the casting furnace 5 as needed to melt and stir, so as to achieve further fine-tuning of the alloy liquid inside the casting furnace 5.
