Description

Technical Field

[0001] This utility model relates to the field of wire rolling nozzle technology, specifically a gas-water-cooled integrated nozzle device for wire rolling. Background Technology

[0002] During the wire rod rolling process, the rolled part generates a large amount of heat after being rolled by the rolls. If it cannot be cooled in a timely and effective manner, it will lead to coarse grains, degraded performance, and even quality problems such as warping and deformation, which will seriously affect the quality of the finished wire rod. The existing wire rod rolling cooling methods mainly adopt separate gas cooling or water cooling. Although separate gas cooling can provide a certain cooling effect, the cooling efficiency is limited due to the relatively small specific heat capacity of gas, which is difficult to meet the production scenarios that require high-speed rolling and high cooling intensity. Water cooling, although it has a strong cooling capacity, has poor cooling uniformity, which can easily lead to uneven temperature distribution on the surface of the wire rod, thereby generating internal stress and affecting the mechanical properties and dimensional accuracy of the wire rod. Utility Model Content

[0003] To achieve the above objectives, this utility model is implemented through the following technical solution: a gas-water-cooled integrated nozzle device for wire rolling, comprising: a fixed flange bracket, a flange clamp, and a flange sleeve, wherein the flange sleeve is mounted on the fixed flange bracket by means of the flange clamp, and an integrated high-efficiency nozzle structure is installed on the flange sleeve.

[0004] The integrated high-efficiency nozzle structure includes: an outer nozzle ring, a jet channel, several air blowing nozzles, an air inlet box, a premixing chamber, an air inlet connector, a water spray channel, several water spray nozzles, and a pair of water injection connectors;

[0005] The nozzle outer ring assembly is mounted on the flange sleeve. The jet channel is located at the front of the nozzle outer ring. Several air-blowing nozzles are mounted on the inner wall of the nozzle outer ring and connected to the jet channel. The air inlet box is mounted at the top of the nozzle outer ring. The premixing chamber is located inside the air inlet box and connected to the jet channel. The air inlet connector is embedded in the air inlet box. The water spray channel is located at the rear of the nozzle outer ring. Several water spray heads are embedded on the inner wall of the nozzle outer ring and located behind the air-blowing nozzles. A pair of water injection connectors are mounted on both sides of the nozzle outer ring and connected to the water spray channel.

[0006] Preferably, the air nozzles are grouped and radially inclined at °.

[0007] Preferably, the spray head is a fan-shaped spray head, and the groups are evenly arranged on the outer ring of the nozzle.

[0008] Preferably, the middle part of the spray head has a spherical connection structure, which can be adjusted by ±° angle.

[0009] Preferably, a mixing baffle is provided inside the premixing chamber.

[0010] Beneficial effects

[0011] This utility model provides a gas-water cooled integrated nozzle device for wire rod rolling, which has the following advantages: This solution uses an integrated high-efficiency nozzle structure. The overall device has a ring structure, allowing the gas and water jets to act simultaneously on the surface of the rolled piece. Gas cooling can quickly remove some of the heat from the surface of the rolled piece, while water cooling utilizes its large specific heat capacity to further enhance the cooling effect, greatly improving cooling efficiency. This can meet the production scenarios requiring high-speed rolling and high cooling intensity, effectively ensuring the quality of the finished wire rod. By rationally setting the position, number, and spray angle of the air blowing nozzles and water spray nozzles, uniform spraying of gas and water is achieved. The air blowing nozzles are set radially at a 30° angle, which allows the gas to be blown evenly onto the surface of the rolled piece at a certain angle; The water head uses fan-shaped nozzles evenly distributed on the outer ring of the nozzles, which can form a uniform water curtain covering the surface of the rolled workpiece. This effectively avoids surface temperature differences in the wire rod caused by uneven cooling, reduces the generation of internal stress, and improves the mechanical properties and dimensional accuracy of the wire rod. It solves the problem that the existing wire rod rolling cooling methods mainly use separate gas cooling or water cooling. Although separate gas cooling can provide a certain cooling effect, the cooling efficiency is limited due to the relatively small specific heat capacity of gas, which is difficult to meet the production scenarios with high-speed rolling and high cooling intensity requirements. Water cooling, although having strong cooling capacity, has poor cooling uniformity, which can easily lead to uneven temperature distribution on the surface of the wire rod, thereby generating internal stress and affecting the mechanical properties and dimensional accuracy of the wire rod.

A pair of water injection connectors 12 are installed on both sides of the nozzle outer ring 4 and are connected to the water spray channel 10.

[0021] A fixed flange bracket 1 is installed on the rolling mill production line. A flange sleeve 3 is securely mounted on the fixed flange bracket 1 via flange clamps 2, providing a stable support structure for the entire device and a mounting base for other components. An air jet channel 5 is located inside the outer ring 4 of the nozzle, providing a channel for gas flow. It connects to 12 sets of air-blowing nozzles 6, which are installed on the inner wall of the outer ring 4 and connected to the air jet channel 5. The air-blowing nozzles 6 are radially inclined at 30°. This design allows the blown gas to be sprayed onto the wire surface at a specific angle, increasing the contact area and contact time between the gas and the wire as the rolling mill passes through the outer ring 4 of the nozzle, thus improving the cooling effect. An air inlet box 7 is installed at the top of the outer ring 4 of the nozzle. A premixing chamber 8 is located inside the air inlet box 7 and is connected to the air jet channel 5. It can mix gases such as CO2 and N2 at the air inlet according to production needs, suitable for the production of different wires. The premixing chamber 8... A mixing baffle 13 is provided, which has a fin-shaped structure. The inclined fins on the upper and lower walls of the horizontal plate cause the incoming gas to circulate, increasing the uniform mixing of different gases during delivery and injection. The water spray channel 10 is located inside the outer ring 4 of the nozzle and is positioned at the rear. It works in conjunction with the air jet channel 5 to achieve sequential cooling of gas and water. The water spray head 11 is a fan-shaped nozzle with a total of 8 groups, which are evenly arranged on the outer ring 4 of the nozzle and located behind the air blowing nozzle 6. This layout allows the wire to be cooled by gas first, which initially reduces the temperature and removes some surface impurities. Then, it is cooled by water, which further precisely controls the temperature of the wire. The middle part of the water spray head 11 has a spherical connection structure, which can be adjusted by ±15°. In actual use, the spray angle of the water spray head 11 can be flexibly adjusted according to factors such as wire specifications, rolling speed, and cooling requirements to ensure that water can be accurately and evenly sprayed onto the surface of the wire, thereby improving the cooling effect and cooling efficiency.
