Abstract
Description
Technical Field
[0001] This utility model relates to the field of heating furnace technology, and in particular to a cooling device for the furnace rib tubes of a hot rolling heating furnace. Background Technology
[0002] The function of the furnace rib cooling device in a hot rolling heating furnace is to control the temperature of the furnace rib within a suitable range by controlling the flow of water or cooling medium, so as to ensure that the furnace rib does not overheat, deform or be damaged in a high-temperature working environment. The cooling device can effectively reduce the temperature of the furnace rib, improve its durability and service life, and at the same time maintain the temperature balance in the furnace, ensuring the stability and heating effect of the steel heating process.
[0003] However, the existing cooling devices for the furnace ribs of hot rolling heating furnaces have significant shortcomings. On the one hand, the lack of efficient cooling methods makes it impossible to cool the interior quickly, which not only prolongs the production cycle but may also affect product quality. On the other hand, the internal pipes are easily clogged by impurities and dirt due to long-term exposure to high temperatures and complex media. Frequent cleaning and maintenance increase manpower and time costs, seriously affecting the normal operation and service life of the equipment.
[0004] Therefore, this application provides a cooling device for the furnace rib tubes of a hot-rolled heating furnace to meet the requirements. Utility Model Content

[0012] Furthermore, each of the heating tubes is fixed with a second connecting ring.
[0013] The beneficial effect of adopting the above-mentioned further solution is that the heating tube can be fixed by the second connecting ring.

The gas is first cooled by the first cooling pipe, and the outer arc-shaped pipe assists in enhancing the cooling effect. The cooled gas is discharged from the exhaust port, realizing the recovery and utilization of waste heat, reducing energy consumption, and improving resource utilization.
[0018] Furthermore, a recovery pipe is fixed to the outside of the cooling box, and the other end of the recovery pipe is fixedly connected to the outside of the vaporization box.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0021] 1. When the heating furnace body is working, heat is conducted to the heating tube, which in turn heats the coolant in the storage tube. The vaporization cooling tube utilizes the characteristic that the coolant absorbs a large amount of heat when it vaporizes to cool the heating tube and its surrounding area. This effectively reduces the temperature of the heating tube, prevents it from being damaged by high temperature, ensures the stable operation of the heating furnace, improves the reliability and safety of the hot-rolled material heating process, and helps the hot-rolling production proceed smoothly.
[0022] 2. The cleaning component is used for maintaining the cooling component. It includes a guide rod fixed inside the heating tube, on which a third connecting ring is slidably connected. When cleaning is required, the third connecting ring is pushed to move along the guide rod. The connecting component fixed inside the third connecting ring drives the baffle plate to move. The cleaning steel brush on the fixed ring on the outside of the baffle plate then scrubs the inner wall of the heating tube. Through this operation, dirt and impurities on the inner wall of the heating tube can be effectively removed, ensuring the normal operation of the cooling component and improving the working efficiency of the cooling device.
