Description

Technical Field

[0001] The utility model relates to the technical field of air-through conduit structures, in particular to a closed high-speed wire air-through conduit device. Background Art

[0002] During the rolling process, there is generally a phenomenon of the rolling mill running dry. At this time, an empty conduit must be used to drain the rolled piece. During the rolling process, in order to prevent the roller box seal from being scalded at high temperature, the cooling water must be turned on to cool the conduit. The current conduit consists of two parts, the upper and lower parts. The cooling water will enter the conduit from the gap, causing the temperature of the red steel head to drop, resulting in blackheads and increasing the risk of steel holding back. In addition, the splash of cooling water will also accumulate in the conduit and other positions in the previous stage, which will also reduce the temperature of the red steel head. And its fixing method is to reinforce the guide base on both sides, and there is no constraint on the forward direction of the red steel. Utility Model Content

[0003] The utility model aims to provide a closed high-speed wire rod empty-through conduit device, which avoids cooling water from entering the conduit through the gap, and provides a trumpet-shaped expansion to reduce the impact of cooling water splashing on adjacent conduits, and can constrain and limit the forward direction of the empty-through conduit, thereby improving the stability of the device after installation.

[0004] The above technical objectives of the utility model are achieved through the following technical solutions:

[0005] A closed high-speed wire rod air-passing conduit device comprises an air-passing conduit and a cooling mechanism. The air-passing conduit is integrally arranged, and the cooling mechanism sprays cooling liquid onto the periphery of the air-passing conduit. The air-passing conduit is connected to a first mounting base, and a boss is provided below the first mounting base. The boss is correspondingly connected to a roller box to limit its axial movement; one end of the air-passing conduit is also connected to a trumpet-shaped expansion port, and the outer peripheral surface of the trumpet-shaped expansion port gradually expands outward.

[0006] By adopting the above technical solution, the integrally arranged air-through conduit prevents cooling water from entering the conduit through the gap, and a trumpet-shaped expansion is provided to reduce the impact of cooling water splashing on adjacent conduits. A boss is provided under the first mounting base to constrain and limit the forward direction of the air-through conduit, thereby improving the stability of the device after installation.

[0007] Furthermore, the air passage conduit is also connected to a second mounting base.

[0008] By adopting the above technical solution, the installation position of the air-through conduit is further stabilized by the second installation base, and the second installation base is set to different shapes according to different installation environments.

[0009] Furthermore, the trumpet-shaped expansion port is located at the inlet end of the air-through conduit, and the cover is arranged in the direction of the upper-level conduit.

[0010] By adopting the above technical solution, it is possible to avoid the accumulation of cooling water splashes in the conduit and other locations in the previous stage, which would lead to lowering of the temperature of the red steel head and reduce the risk of steel stagnation.

[0011] Furthermore, a trumpet-shaped guide opening is provided on the inner periphery of the inlet end of the air-through conduit, and the inner periphery of the trumpet-shaped guide opening gradually expands outwards.

[0012] By adopting the above technical solution, the trumpet-shaped guide opening plays a certain guiding and restraining role, ensuring that the red steel rolled piece enters the air passage conduit more smoothly.

[0013] Furthermore, the boss below the first mounting base is provided with several layers to form a stepped surface, and the top of the roller box is correspondingly arranged in a stepped shape, and the cross section of the step close to the outlet end of the air passage conduit is smaller.

[0014] By adopting the above technical solution, the stability of the device is improved, and the constraints and restrictions on the forward direction of the air-through catheter are further improved.

[0015] Furthermore, the cooling mechanism includes a plurality of cooling water pipes, and the spraying direction of the cooling water pipes is arranged toward the direction of the air-through conduit.

[0016] By adopting the above technical solution, the coolant is sprayed through the cooling water pipe to cool the air passage.

[0017] Furthermore, the cooling water pipe sprays the cooling liquid obliquely toward the inlet side of the air passage conduit.

[0018] By adopting the above technical solution, the cooling water moves or splashes toward the inlet end of the air-through conduit, and the inlet end of the air-through conduit can be pre-cooled until it is completely cooled at the position directly facing the cooling water, thereby improving the cooling effect.

[0019] Furthermore, the cooling water pipe is wound around the roller.

[0020] By adopting the above technical solution, the roller is bypassed, the air guide tube is removed, and the roller sleeve is installed on the roller, and then the roller position is cooled.

[0021] In summary, the utility model has the following beneficial effects:

[0022] The integrated air-through conduit prevents cooling water from entering the conduit through the gap, and a trumpet-shaped expansion is provided to reduce the impact of cooling water splashing on adjacent conduits. A boss is provided under the first mounting base to constrain and limit the forward direction of the air-through conduit, thereby improving the stability of the device after installation.

[0023] The trumpet-shaped expansion port is located at the inlet end of the air-through duct, and the cover is set in the direction of the upper-stage duct to prevent the splashing of cooling water in the duct of the previous stage and other positions from accumulating, thereby lowering the temperature of the red steel head and reducing the risk of steel stagnation;

[0024] A trumpet-shaped guide opening is provided on the inner periphery of the inlet end of the air-through conduit, which plays a certain guiding and restraining role, ensuring that the red steel rolled piece enters the air-through conduit more smoothly; the cooling water pipe sprays the coolant in an inclined direction toward the inlet side of the air-through conduit, so that the cooling water moves or splashes toward the inlet end of the air-through conduit, and the inlet end of the air-through conduit can be pre-cooled until it is completely cooled at the position directly facing the cooling water, thereby improving the cooling effect;

[0032] A closed high-speed wire air-through catheter device, such as Figure 1 and Figure 2As shown, it includes an air-through conduit 3 and a cooling mechanism. The air-through conduit 3 is integrally arranged. The cooling mechanism sprays coolant onto the periphery of the air-through conduit 3. A first mounting base 1 is connected to the air-through conduit 3. The first mounting base 1 can be integrally arranged with the air-through conduit 3, or can be connected by sleeve arrangement and welding fixation to ensure that it is watertight. A second mounting base 4 is also connected to the air-through conduit 3. The second mounting base 4 is connected to the air-through conduit 3 by means of screws or the like, and is set to different shapes according to the installation environment. In this embodiment, the second mounting base 4 is U-shaped.

[0033] like Figure 1 As shown, a boss 2 is provided below the first mounting base 1, and is connected to the roller box via the boss 2 (a groove is provided on the roller box or abuts against the end surface), and is connected to the roller box via the boss 2 to limit its axial movement (movement in the forward direction);

[0034] The boss 2 below the first mounting base 1 can be arranged in several layers (each layer is relatively small in thickness) to form a step surface, and the top of the roller box is correspondingly arranged in a step shape, and the step cross-section on the side close to the outlet end of the air-through duct 3 is smaller, further improving the constraints and restrictions on the forward direction of the air-through duct 3.

[0035] like Figure 2 and Figure 3 As shown, one end of the air-through conduit 3 is also connected to a trumpet-shaped expansion port 5, and the outer peripheral surface of the trumpet-shaped expansion port 5 gradually expands outward; the trumpet-shaped expansion port 5 is located at the inlet end of the air-through conduit 3, and is shielded in the direction of the upper-level conduit 9 to prevent the splashing of cooling water in the previous stage conduit and other positions from accumulating, thereby reducing the temperature of the red steel head and reducing the risk of steel stagnation;

[0036] A trumpet-shaped guide opening 6 is provided at the inner periphery of the entrance end of the air-through conduit 3 , and the inner periphery of the trumpet-shaped guide opening 6 gradually expands outwards, playing a certain guiding and restraining role, thereby ensuring that the red steel rolled piece enters the air-through conduit 3 more smoothly.

[0037] like Figure 3 As shown, the cooling mechanism includes a plurality of cooling water pipes 8, and the spraying direction of the cooling water pipes 8 is arranged toward the air-through conduit 3; the cooling water pipes 8 spray the coolant obliquely toward the inlet side of the air-through conduit 3, so that the cooling water moves or splashes toward the inlet end of the air-through conduit 3, and the inlet end of the air-through conduit 3 can be pre-cooled until it is completely cooled at the position directly facing the cooling water, thereby improving the cooling effect;

[0038] In this embodiment, the cooling water pipe 8 is wound around the roller 7 and is provided with a main injection port for oblique injection facing the air-through duct 3 and a plurality of auxiliary injection ports facing the outer periphery of the roller 7.
