Description

Technical Field

[0001] The present application relates to the technical field of continuous steel rolling, and in particular to a looper assembly cooling device. Background Art

[0002] The looper assembly plays a crucial role in regulating the smooth operation of the rolling mill and is also a key piece of equipment for product quality control. Its primary function is to adjust the rolling tension between the rolling mills, maintaining a constant tension on the workpiece during the rolling process. When the piston rod of the looper cylinder retracts, it drives the looper roller upward, pulling on the workpiece and increasing its tension. When the piston rod extends, the looper roller moves downward, reducing the workpiece tension.

[0003] The current cooling system for the bar looper assembly consists of a cooling hose consisting of four sections of rubber hose and a section of T-shaped rigid pipe. The cooling water pipe for the looper roll is connected to the bottom plate of the looper roll bearing seat. Each time the looper roll is replaced, the cooling water pipe must be removed and then reconnected after the roll is replaced. This setup increases roll change time by requiring the cooling water pipe to be removed and reconnected. Furthermore, the looper roll water pipe moves up and down with the roll, leading to a high rate of breakage or detachment, which affects the production rhythm and efficiency of the rolling line.

Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different viewpoints and applications without departing from the spirit of the present invention.

[0023] See also Figure 1 , Figure 1 Schematic diagram of the structure of the looper assembly cooling device shown in an exemplary embodiment of the present application. Figure 1 It can be seen that the looper assembly cooling device may include:

[0024] Inlet cooling section 110 , outlet cooling section 120 and water inlet connecting section 130 .

[0025] One end of the inlet cooling section 110 is open and the other end is closed. The inlet cooling section 110 is located on the steel inlet side of the looper assembly. The inlet cooling section 110 is provided with an inlet roller cooling water hole 111 ( Figure 1 (not shown), the inlet cooling section 110 is provided with a sleeving roller cooling water hole 112 in the direction of the sleeving roller of the sleeving assembly.

[0026] In some embodiments, the cooling water holes 112 of the sleeving roller are strip-shaped holes. Since the sleeving roller moves up and down, the provision of the strip-shaped holes can facilitate the cooling water to cool the sleeving roller during the movement of the sleeving roller.

[0027] In the embodiment of the present application, the centerline of the looper roll cooling water hole 112 is angled 60 degrees from the vertical. This design allows the looper roll cooling water to flow downward from an oblique upward direction, directly cooling the contact point between the workpiece and the roll. This provides a better cooling effect and makes it easier to check whether the water pipe is spraying water normally and whether the looper roll is cooled properly.

[0028] One end of the outlet cooling section 120 is open and the other end is closed. The outlet cooling section 120 is located on the steel-outlet side of the looper assembly. The outlet cooling section 120 is provided with an outlet roller cooling water hole 121 facing the outlet roller of the looper assembly.

[0029] The water inlet connection section 130 has one end connected to the opening of the inlet cooling section 110 and the other end connected to the opening of the outlet cooling section 120. The water inlet connection section 130 is provided with a water inlet hole 131 for connecting to the water inlet pipe. The outer wall of the water inlet hole 131 can be provided with a thread matching the water inlet pipe for easy connection.

[0030] It should be noted that when using the looper assembly cooling device provided in the embodiment of the present application, the water inlet pipe is connected to the water inlet connecting section 130. After the water supply is started, the water flows from the inlet pressure roller cooling water hole 111 to the inlet pressure roller, from the loosening roller cooling water hole 112 to the loosening roller, and from the outlet pressure roller cooling water hole 121 to the outlet pressure roller.

[0031] In one embodiment of the present application, the inlet pressure roller cooling water holes 111 are arranged at intervals along the axial direction of the inlet cooling section 110, the jacketing roller cooling water holes 112 are arranged at intervals along the axial direction of the inlet cooling section 110, and the outlet pressure roller cooling water holes 121 are arranged at intervals along the axial direction of the outlet cooling section 120. The inlet pressure roller cooling water holes 111 and the jacketing roller cooling water holes 112 are not connected, that is, the inlet pressure roller cooling water holes 111 and the jacketing roller cooling water holes 112 are independent of each other.

[0032] See also Figure 2, which is a structural diagram of the looper assembly cooling device provided in an embodiment of the present application from another perspective. The angle between the center line of the water inlet hole 131 and the vertical direction can be set to 15 degrees. This setting can facilitate the disassembly of the water inlet pipe.

[0033] See also Figure 3 , which is a structural diagram of the loop assembly cooling device provided in an embodiment of the present application and the use of the loop assembly in conjunction. In some embodiments, the water inlet connecting section 130 is a U-shaped structure with an opening facing downward, and the inlet cooling section 110 and the outlet cooling section 120 are respectively connected to the two ends of the water inlet connecting section 130. The loop assembly 200 is provided with a detection position 204 for installing a detection element, and the detection element is located between the inlet pressure roller 201 and the outlet pressure roller 203. In order to avoid the influence of the loop assembly cooling device 100 on the detection element, the water inlet connecting section 130 of the loop assembly cooling device 100 can be set to a U-shaped structure with an opening facing downward. It should be noted that when using the loop assembly cooling device 100 provided in an embodiment of the present application, the loop assembly cooling device 100 can be welded to the loop assembly. The looper assembly 200 is provided with an inlet pressure roller 201, a lifting roller 202 and an outlet pressure roller 203. When using the looper assembly cooling device 100 provided in the embodiment of the present application, after connecting the water inlet pipe and passing water, water can be sprayed on each roller through the cooling water holes corresponding to each roller for cooling.

[0034] In the embodiment of the present application, the looper assembly cooling device is formed in one piece and is made of steel.

[0035] It should be noted that in order to make the looper assembly cooling device better cooperate with the looper, the accurate size of the on-site looper assembly can be measured and a set of one-piece looper assembly cooling device can be designed. For example, a seamless steel pipe with a nominal inner diameter of DN32, an outer diameter of Φ42, and a wall thickness of 5mm can be used to make a looper assembly cooling device, wherein the positioning of the cooling water hole of the looper roller is an important design point (the cooling water hole of the looper roller can be a strip hole, and the center line of the strip hole is at a 60° angle to the vertical direction), which is beneficial for water cooling during the lifting and lowering of the looper roller and during the movement. The specific design size of the looper assembly cooling device can be designed by the operator according to the size of the looper assembly.

[0036] The looper assembly cooling device provided in the embodiment of the present application has the following effects:

[0037] 1. In the prior art looper cooling method, the hose clamp is prone to breakage and detachment. The clamp fastening bolts are corroded by water over time, making them difficult or impossible to remove after rusting, and replacing the water pipe takes a long time. The water pipe is integrally formed from a seamless steel pipe with no redundant joints in the middle, effectively reducing the number of failure points in the looper cooling device and ensuring the stability of continuous rolling production.

[0038] 2. The inlet pressure roller and the jacketing roller share a cooling water pipe (also known as the inlet cooling section). The cooling water of the jacketing roller rushes down from the upper direction to directly cool the contact position between the rolled piece and the roller, which has a better cooling effect.

[0039] 3. The lapping roller is no longer equipped with a separate cooling water pipe, which is beautiful and simple. When replacing the lapping roller, there is no need to dismantle the connected cooling water pipe, which greatly shortens the replacement time of the lapping roller.

[0040] In summary, an embodiment of the present application provides a looper assembly cooling device, which includes an inlet cooling section, an outlet cooling section, and a water inlet connecting section. The inlet cooling section is located on the steel inlet side of the looper assembly, one end of the inlet cooling section is open and the other end is closed, the inlet cooling section is provided with an inlet pressure roller cooling water hole in the direction of the inlet pressure roller of the looper assembly, and a take-off roller cooling water hole is provided in the direction of the take-off roller of the looper assembly. The outlet cooling section is located on the steel outlet side of the looper assembly, one end of the outlet cooling section is open and the other end is closed, the outlet cooling section is provided with an outlet pressure roller cooling water hole in the direction of the outlet pressure roller of the looper assembly, and a water inlet connecting section, one end of the water inlet connecting section is connected to the opening of the inlet cooling section, and the other end is connected to the opening of the outlet cooling section, and the water inlet connecting section is provided with a water inlet hole for connecting to a water inlet pipe. The inlet pressure roller and the take-off roller share a cooling water pipe (that is, the inlet cooling section), and replacing the take-off roller no longer requires disassembling the connected cooling water pipe, which greatly shortens the replacement time of the take-off roller.

[0042] The above embodiments are merely illustrative of the principles and effects of this application and are not intended to limit this application. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of this application. Therefore, any equivalent modifications or alterations accomplished by a person of ordinary skill in the art without departing from the spirit and technical concepts disclosed in this application shall be covered by the claims of this application.
