Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of blackbody energy-saving components, and in particular relates to a heat transfer element with a surrounding groove. Background Technology
[0002] Inside the furnace of a steel rolling heating furnace, the extensiveness of the furnace structure can be significantly optimized by deploying tens of thousands of cup-shaped energy-saving units that are closed at the rear and open at the front. This design achieves the following technical effects by expanding the effective heat exchange area of the furnace inner wall: 1. Enhanced furnace heat transfer efficiency, shortening the metal billet heating cycle; 2. Reduced fuel consumption and energy loss; 3. Improved metal heating uniformity, enhancing rolled product quality; 4. Increased production capacity per unit time through improved thermal efficiency. This effectively resolves the technical contradiction between heat transfer efficiency and energy consumption control in traditional heating furnaces.
[0003] However, after the heat transfer elements are installed, the effective heat transfer area expansion coefficient of the furnace inner wall is difficult to increase due to the structural design parameters of the heat transfer elements, which limits the improvement of heat conduction efficiency and affects the optimization space of energy conversion rate. The heat transfer elements themselves are heavy and are prone to the attenuation of interface bonding force under high temperature alternating stress, causing the risk of displacement failure of the heat transfer elements, hindering the sustainability of equipment upgrades, and thus causing the energy efficiency improvement curve of the heating furnace to slow down. Utility Model Content
[0004] To address the shortcomings of the existing technology, this utility model provides a heat transfer element with an enclosing groove, which reduces the weight of the heat transfer element, expands the heat transfer area of the furnace, improves the energy conversion rate, extends the service life, and achieves energy saving and emission reduction.
[0005] In order to achieve the purpose of this utility model, the following solution is proposed:
[0006] A heat transfer element with enclosing grooves includes a main element, one end of which is recessed with a cylindrical cavity, the top of which is provided with a connecting hole that communicates with the cavity, the surface of the main element is provided with a plurality of first enclosing grooves evenly distributed, and the inner surface is provided with a plurality of second enclosing grooves evenly distributed, the first enclosing grooves and the second enclosing grooves being arranged alternately and in parallel.
[0007] Furthermore, the depth of the first and second enclosing grooves is the same, and both are half the wall thickness of the main component.
[0008] Furthermore, both the first and second enclosing grooves are strip-shaped structures, and the length directions of the first and second enclosing grooves are consistent with the height direction of the main component.
[0009] The beneficial effects of this utility model are as follows:
[0010] A first reinforcing groove is provided on the outer wall of the main component, and a second reinforcing groove is provided on the inner wall. The first and second reinforcing grooves are staggered. This reduces the weight of the main component while ensuring its strength, saves on materials, and increases the surface area of the main component. This increases the furnace enclosure extension, enhances the heat transfer intensity of the heating furnace, and achieves energy saving and emission reduction. Attached Figure Description

[0018] The markings in the diagram are: main component-1, connecting hole-11, cavity-2, first surrounding groove-3, and second surrounding groove-4. Detailed Implementation
[0019] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.
[0020] like Figures 1-6 As shown, this embodiment provides a heat transfer element with a surrounding groove, including a main element 1, a cavity 2 recessed inward along the lower end of the main element 1, and a connecting hole 11 on the top of the main element 1, which communicates with the cavity 2 for installing a connector between the main element 1 and the heating furnace.
[0021] The outer surface of the main component 1 is evenly distributed with first reinforcing grooves 3 and the inner surface is evenly distributed with second reinforcing grooves 4. The first reinforcing grooves 3 and the second reinforcing grooves 4 are arranged alternately and in parallel. While ensuring the strength of the main component 1, the surface area of the main component can be increased to increase the furnace enclosure extension and enhance the heat transfer intensity of the heating furnace.
[0022] like Figures 1-2 As shown, the first reinforcing groove 3 and the second reinforcing groove 4 have a strip-shaped structure. The first reinforcing groove 3 is arranged in a circumferential array on the outer wall of the main component 1, and the two ends of the first reinforcing groove 3 are respectively connected to the upper and lower ends of the main component 1. The second reinforcing groove 4 is arranged in a circumferential array on the inner wall of the cavity 2, and the lower end of the second reinforcing groove 4 is connected to the lower ends of the cavity 2. This further reduces the weight of the main component 1, making the main component 1 lightweight, and increases the furnace enclosure extension, significantly enhancing the heat transfer intensity of the heating furnace. Moreover, with a lighter weight, the main component 1 can be more firmly bonded to the furnace foundation for a long time, ensuring the continuous energy-saving transformation efficiency of the heating furnace.
[0023] Preferred, such as Figures 3-4 As shown, the first enclosing groove 3 and the second enclosing groove 4 are in the form of a ring structure. The first enclosing groove 3 is arranged in an array along the height direction of the main body element 1 on the outer wall of the main body element 1, and the second enclosing groove 4 is arranged in an array along the height direction of the main body element 1 in the cavity 2, and the first enclosing groove 3 and the second enclosing groove 4 are arranged alternately.
[0024] Preferred, such as Figures 5-6 As shown, a first spiral groove 3 with a spiral structure is provided on the outer wall of the main component 1, and a second spiral groove 4 with a spiral structure is provided on the inner wall of the cavity 2. The starting points of the first spiral groove 3 and the second spiral groove 4 are arranged opposite to each other, so that the first spiral groove 3 and the second spiral groove 4 are arranged alternately and the pitch of the first spiral groove 3 and the second spiral groove 4 is the same.
[0025] The above description is merely a preferred embodiment of this utility model and does not imply its uniqueness or limitation. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
