Description

Technical Field

[0001] The utility model relates to the technical field of oxygen-free copper rod continuous casting machine sets, in particular to an upward oxygen-free copper rod continuous casting machine set. Background Art

[0002] The upward oxygen-free copper rod continuous casting unit is used to produce long bright oxygen-free copper rods, long bright oxygen-free copper tubes and long bright oxygen-free copper slabs. The unit can directly produce rods, tubes, slabs or other special-shaped materials of different specifications from electrolytic copper by continuous melting and casting. The unit is divided into four levels according to annual production capacity: 2,000 tons, 3,000 tons, 4,000-60,000 tons and 8,000-12,000 tons.

[0003] During the use of the existing continuous casting unit, when the lead rod is pulled out of the crystallizer, the copper rod is mostly cooled by natural heat dissipation. However, the natural cooling efficiency is poor, which often affects the subsequent winding process of the copper rod. For this reason, we propose an upward-pulling oxygen-free copper rod continuous casting unit that can efficiently cool the copper rod. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide an upward oxygen-free copper rod continuous casting unit to solve the technical problems mentioned in the above background.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an upward oxygen-free copper rod continuous casting unit, comprising a unit body, a crystallizer is installed inside the unit body, and a copper rod is installed inside the crystallizer, a heat dissipation ring is sleeved on the outer side of the copper rod, and a plurality of groups of annularly distributed nozzles are installed on the inner side of the heat dissipation ring, an air supply pipe for supplying air to the nozzle is installed inside the heat dissipation ring, and the outer wall of the air supply pipe is connected to an air inlet pipe connected to an external air supply device.

[0006] By adopting the above technical solution, high-quality heat dissipation can be performed on the copper rod, thereby ensuring the subsequent winding process.

[0007] The utility model is further configured that an electric guide rail is installed on the outside of the heat dissipation ring, and two groups of sliders symmetrically distributed and adapted to the electric guide rail are arranged inside the electric guide rail, and the outer wall of the slider extends to the outer wall of the heat dissipation ring and is fixedly connected to the outer wall of the heat dissipation ring.

[0008] By adopting the above technical solution, a driving effect on the heat dissipation ring is achieved.

[0009] The utility model is further configured such that a water cooling chamber is provided inside the heat dissipation ring on the outside of the air supply pipe, and the inside of the water cooling chamber is filled with coolant, a first water pump for pumping water and a second water pump for replenishing water are respectively installed on both sides of the heat dissipation ring, and an input end of the first water pump is connected to a first telescopic tube communicating with the water cooling chamber, and an output end of the second water pump is connected to a second telescopic tube communicating with the water cooling chamber.

[0010] By adopting the above technical solution, a water cooling effect is achieved on the air supply pipe.

[0011] The utility model is further configured such that the outer wall of one group of the sliders is fixedly connected to a first extrusion rod, and a first control switch is installed on one side of the first extrusion rod, and the outer wall of another group of the sliders is fixedly connected to a second extrusion rod, and a second control switch is installed on one side of the second extrusion rod.

[0012] By adopting the above technical solution, a driving effect on the control switch is achieved.

[0013] The utility model is further configured such that the first control switch is electrically connected to the first water pump via a single chip microcomputer, and the second control switch is electrically connected to the second water pump via a single chip microcomputer.

[0014] By adopting the above technical solution, the water pump can be electrically controlled.

[0015] In summary, the utility model mainly has the following beneficial effects:

[0016] 1. The utility model provides a heat dissipation ring, an electric guide rail and a nozzle. After the copper rod moves upward to complete a set of winding processes, it will be efficiently cooled when passing through the heat dissipation ring. Specifically, the air intake pipe will transport the external heat dissipation gas to the air supply pipe, and the nozzle will absorb gas from the air supply pipe and spray it out, thereby achieving high-quality heat dissipation of the copper rod. Furthermore, the coolant in the water-cooling chamber can perform heat dissipation treatment on the air supply pipe, thereby further improving the cooling degree of the heat dissipation gas, thereby further improving the heat dissipation effect. In addition, the electric guide rail will also drive the slider to move, so that the slider drives the heat dissipation ring to move, so that the heat dissipation ring drives the nozzle to rotate on the outer wall of the copper rod, thereby expanding the effective area of ​​the nozzle, and achieving all-round and efficient heat dissipation of the copper rod;

[0017] 2. The utility model provides an extrusion rod, a control switch and a water pump. When the electric guide rail is running, the movement of the slider will squeeze the first control switch through the first extrusion rod, so that the first control switch controls the first water pump through the single-chip microcomputer to extract a part of the coolant in the water-cooling chamber. When the slider moves in the opposite direction, it squeezes the second control switch through the second extrusion rod, so that the second control switch controls the second water pump through the single-chip microcomputer to replenish the water-cooling chamber, effectively ensuring the cooling effect of the water-cooling chamber and further improving the heat dissipation efficiency.
