Description
Technical Field
The application relates to the technical field of laying pipes, in particular to a high-heat-dissipation laying pipe and a cooling method thereof.
Background
Wire is one of the important varieties of steel products, and is widely applied to the building and product industries. At present, the countries mainly producing steel generally adopt a full-continuous high-speed torsion-free wire rod finishing mill group and a controlled cooling technology as main process equipment means for wire rod production.
High speed wire production is a continuous process from billet to finished product, and the laying head laying pipe is a key device for controlling the transition of wire from straight line to wire rod. The temperature of the rolled piece after finish rolling is kept at 850 ℃ approximately, the speed can be as high as 120m/s, after the rolled piece enters a spinning pipe, the wire rod moves forwards according to the spinning pipe under the comprehensive actions of driving force, relative inertia force, friction force, positive pressure and the like caused by a pinch roll and a spinning machine, the linear motion is changed into spiral motion, a stable coil with the diameter of 1080mm is formed, and the stable coil is discharged from the spinning pipe and evenly laid on a roller way.
In a paper entitled "study and improvement of spatial curves of a laying pipe of a high-speed wire laying machine", published in journal of China engineering science 2006, volume 8, volume 11, it is described that when a laying pipe works, wires move forward in the laying pipe and are subjected to backward frictional resistance of the wall of the laying pipe; the profile of the friction experienced by the inner wall of the laying pipe is also described (as shown in FIG. 5).
Through research and analysis, the wire is subjected to rapid increase after entering the inlet of the spinning pipe, and the position with the maximum friction force is about 500mm away from the inlet of the spinning pipe, namely the first section bending area of the spinning pipe; the inner wall of the laying pipe in the area is severely abraded, and even the laying pipe can be worn through after long-time work, so that steel piling accidents occur.
On the basis, the inventor finds that the first bending area of the laying pipe is severely abraded, the temperature of the pipe body of the first bending area of the laying pipe is far higher than that of the pipe bodies of other areas except for the reason of the maximum friction force, and the high temperature factor is also an important reason for severe abrasion of the first bending area of the laying pipe.
Abnormal wear of the laying pipe leading to excessively short service life and laying anomalies has been a major problem in wire production.

Detailed Description
The present application is described in further detail below with reference to the attached drawings.
Referring to fig. 1, the laying pipe includes a pipe body 1, the pipe body 1 is sequentially provided with a straight line introduction section 1A, a bending deformation section 1B, and a stabilization section 1C along an input end to an output end thereof, and the straight line introduction section 1A, the bending deformation section 1B, and the stabilization section 1C are integrally formed. The tubular body 1 is made of a thermally stable material or a wear resistant material.
When the laying pipe works, the hot rolled product can rotate around the axis of the laying pipe, passes through the laying pipe, changes the linear motion into the spiral motion in the laying pipe, and forms a stable coil to be laid out from the laying pipe.
It has been found that the inner wall of the laying pipe tends to receive the maximum friction force in the transition region L between the straight introduction section 1A and the bending deformation section 1B, the temperature of the pipe wall at the transition region L rapidly rises under the strong friction with the wire, and the transition region L of the laying pipe finally generates accelerated local wear under the influence of the friction force and high temperature.
At present, the spinning pipe is cooled by an air cooling mode, but the heat conductivity coefficient of the pipe body 1 made of wear-resistant materials is low, and heat energy at the transition area L of the pipe body 1 is difficult to dissipate, so that the transition area L of the pipe body 1 becomes a heat affected zone which is almost as hot as the wire rod, and the temperature of the pipe body 1 at the peripheral area is relatively low and is about 400 ℃; in this case, external cooling is difficult to effectively reduce the temperature of the heat affected zone of the laying pipe. Accordingly, the present application provides a laying pipe with high heat dissipation.
Example 1
The high heat dissipating laying pipe includes single-deck body 2, and single-deck body 2 sets gradually into sharp leading-in section 1A, bending deformation section 1B and stable section 1C along its input to output, and sharp leading-in section 1A, bending deformation section 1B and stable section 1C integrated into one piece. The transition area L between the straight line leading-in section 1A and the bending deformation section 1B of the single-layer pipe body 2 is a heat affected zone.
Referring to fig. 2, the single-layer tube 2 is provided with a heat conducting structure 3 extending to the linear introduction section 1A and the bending deformation section 1B at the heat affected zone, the heat conducting structure 3 is a copper or aluminum coating/layer, and the heat conducting structure 3 may partially cover the single-layer tube 2 or completely cover the single-layer tube 2.
The copper or aluminum heat conducting structure 3 has good heat conducting performance, transfers heat energy of the heat affected zone of the single-layer pipe body 2 to the peripheral area, increases the heat radiating area of the single-layer pipe body 2, avoids heating of a single point, and accordingly reduces the influence of high temperature on the abrasion condition of the heat affected zone of the single-layer pipe body 2.
Referring to fig. 3, a plurality of groups of fins 4 are arranged on the heat conducting structure 3, and the plurality of groups of fins 4 are spirally arranged along the axis of the single-layer tube body 2; or the fins 4 are directly arranged on the single-layer tube body 2 as the heat conducting structure 3 and extend from the heat affected zone to the peripheral space area; the material of the fins 4 can be selected from copper or aluminum.
The spirally distributed fins 4 increase the heat dissipation area of the heat conduction structure 3, and the fins 4 rotate synchronously with the laying pipe to accelerate the heat exchange between the fins 4 and the surrounding environment.
When the high-heat-dissipation spinning pipe is cooled down in an accelerated mode, air flow and/or water mist is blown to the high-heat-dissipation spinning pipe, the air flow and/or the water mist is blown to the inside and/or the outside of the high-heat-dissipation spinning pipe, and heat dissipation of the high-heat-dissipation spinning pipe is accelerated through the air flow and/or the water mist.
Example 2
The high-heat-dissipation spinning pipe comprises a double-layer pipe body, wherein the double-layer pipe body comprises an inner pipe 5 and an outer pipe 6 which are equal in length, and the inner pipe 5 and the outer pipe 6 respectively comprise a linear leading-in section 1A, a bending deformation section 1B and a stable section 1C which are integrally formed; an installation gap is formed between the inner pipe 5 and the outer pipe 6, and the installation gap at the end part of the double-layer pipe body 1 is closed.
The material of the inner tube 5 can be selected from spring steel, duplex stainless steel, high-speed steel, precipitation hardening stainless steel, high manganese steel, nodular cast iron and the like. The transition area L of the straight line leading-in section 1A and the bending deformation section 1B of the double-layer pipe body is a heat affected zone.
Referring to fig. 4, a heat conducting structure 3 extending to the linear lead-in section 1A and the bending deformation section 1B is disposed between the inner pipe and the outer pipe of the double-layer pipe body at the heat affected zone, the heat conducting structure 3 is a copper or aluminum coating/layer, and the heat conducting structure 3 may partially cover the inner pipe 5 in the installation gap or completely cover the inner pipe 5.
A plurality of groups of fins can be arranged on the outer pipe 6 of the double-layer pipe body and are spirally arranged along the axis of the double-layer pipe body; the material of the fin can be selected from copper or aluminum. The spirally distributed fins increase the heat dissipation area of the heat conduction structure on one hand, and on the other hand, the fins can synchronously rotate along with the laying pipe, so that the heat exchange between the fins and the surrounding environment is accelerated.
When the high-heat-dissipation spinning pipe is cooled down in an accelerated mode, air flow and/or water mist is blown to the high-heat-dissipation spinning pipe, the air flow and/or the water mist is blown to the inside and/or the outside of the high-heat-dissipation spinning pipe, and heat dissipation of the high-heat-dissipation spinning pipe is accelerated through the air flow and/or the water mist.
