Description

Technical Field

[0001] This utility model relates to the field of heating furnace technology, specifically to a fiber furnace top that is easy to maintain. Background Technology

[0002] The heating furnace is a core thermal equipment in the steel rolling production line of the iron and steel industry. It is specifically used to heat steel billets (square billets, slabs, flat billets, etc.) to a uniform and suitable high-temperature state for plastic deformation before rolling (usually between 1100°C and 1300°C). Its performance directly determines the stability of the rolling process, the quality of the rolled product, energy consumption, and output. Heating furnaces have relatively high requirements for high-temperature resistance and heat preservation; poor heat preservation will result in a large amount of heat loss.

[0003] The shortcomings of existing technology:

[0004] Application No. 201610054237.7 discloses a flat regenerative furnace roof. Although the patent describes a flat regenerative furnace roof composed of several parallel modules, it is mainly for the application of all-fiber furnace roofs in large industrial furnaces such as hot rolling heating furnaces. The application effect is significant, the service life is long, and the processing technology is simple and the manufacturing efficiency is high. However, the parallel modules in this device form a rectangular structure, and the fiber insulation structure on the two modules is located at the lower end of the steel structure, which makes maintenance at the splice inconvenient.

Each fiber insulation unit includes a steel structure and several fiber insulation modules fixed to the lower end of the steel structure. The width of the steel structure is smaller than the width of the fiber insulation modules. After the fiber insulation units are spliced, an inspection groove is formed at the upper end of the splice seam of the fiber insulation modules for subsequent inspection of the splice seam between two adjacent fiber insulation units.

[0007] Preferably, the steel structure includes a steel frame and a connecting plate, the lower end of the steel frame is connected to the upper surface of the connecting plate around the perimeter, and the steel frame and the connecting plate have the same width and are both smaller than the width of the fiber insulation module.

[0023] Example 1

[0024] Please see Figure 1-2 As shown, this utility model provides a fiber furnace top that is easy to maintain, including several spliced ​​and fixed fiber insulation units 1. Each fiber insulation unit 1 includes a steel structure 2 and several fiber insulation modules 3 fixed to the lower end of the steel structure 2. The width of the steel structure 2 is smaller than the width of the fiber insulation modules 3. After the fiber insulation units 1 are spliced, an inspection groove is formed at the upper end of the splice seam of the fiber insulation modules 3 for later inspection of the splice seam of two adjacent fiber insulation units 1. The overall cross-section of the fiber insulation unit 1 is convex. The lower ends of two spliced ​​fiber insulation units 1 are in close contact, and the upper end is provided with a notch to facilitate later inspection of the splice.

[0025] The steel structure 2 includes a steel frame 21 and a connecting plate 22. The lower end of the steel frame 21 is connected to the upper surface of the connecting plate 22 around the perimeter. The steel frame 21 and the connecting plate 22 have the same width and are both smaller than the width of the fiber insulation module 3. The two steel frames 21 form an inspection channel, which can directly repair the splicing seam between the fiber insulation modules 3 on the two fiber insulation units 1.

[0026] The steel frame 21 includes two side steel plates 211 and several crossbars 212 disposed between the two side steel plates 211. The two ends of the crossbars 212 are vertically disposed at the upper ends of the two side steel plates 211, and the connecting plate 22 is fixedly connected to the lower ends of the two side steel plates 211. While ensuring the overall strength of the steel frame 21, it can reduce the overall weight and facilitate installation.

[0027] The connecting plate 22 is a metal grid. In other embodiments, the connecting plate 22 has an installation port, and the installation port is provided with a plurality of lifting beams 221 for connecting with the fiber insulation module 3.

[0028] The steel structure 2 and the fiber insulation module 3 are connected by a connecting assembly. This assembly includes a fastener for connecting to the steel structure and a connector for fixing the fiber insulation module 3. The lower end of the fastener connects to the connector. The fastener includes a fixing bolt, the lower end of which passes through a through hole in the connecting plate 22 and connects to the connector. Specifically, the fixing bolt passes through the through hole in the connecting plate 22 and connects to the threaded structure on the connector. The connector includes an anchor plate connected to the lower end of the fixing bolt and a crossbar for installing the fiber insulation module 3. The anchor plate includes a support portion and a connecting portion. The connecting portion is integrally formed on both sides of the support portion. The support portion and the connecting portion are formed by stamping, a quick and simple processing method with low manufacturing cost. The support portion is used to connect the hoisted steel structure 2, which overlaps the furnace wall. The connecting portion is used to connect to the metal parts for inserting the fiber cloth. The support portion has threaded holes, and the hoisted steel structure 2 is fixed to the support portion by fixing bolts. This fixing method is simple, quick, and provides better stability. The connecting part has a through hole. A crossbar is inserted through the through hole, and the cut fiber cloth is stacked together and then pressed onto the crossbar using a stamping device. The cross-section of the support part is arrow-shaped to ensure sufficient connection strength and prevent deformation under pressure after long-term use. The connecting part is diamond-shaped, facilitating insertion into the fiber cloth gaps while providing sufficient strength for stable suspending of the fiber cloth. The connector also includes a fixing nut, located at the upper or lower end of the threaded hole and fixed to the anchor plate. The lower end of the fixing bolt is threaded to the fixing nut to strengthen the connection between the fixing bolt and the anchor plate.

[0029] Limiting plates 4 are provided on both sides of the steel frame 21. The cross-section of the limiting plate 4 is convex, and the lower part has the same specifications as the fiber insulation module 3. It is used to limit the two sides of the fiber insulation module 3.
