Description

Technical Field

[0001] This utility model belongs to the field of refractory prefabrication technology, and particularly relates to a refractory prefabrication for industrial furnaces. Background Technology

[0002] An industrial furnace is a thermal equipment used in industrial production to heat materials or workpieces using the heat from fuel combustion or electrical energy conversion. Refractory prefabricated components are refractory material products that are pre-cast, cured, and baked in a factory and then transported directly to the industrial furnace site for installation.

[0003] Existing refractory prefabricated components for industrial furnaces are prone to misalignment during assembly, leading to unstable assembly. Therefore, we propose a new type of refractory prefabricated component for industrial furnaces. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a refractory prefabrication for industrial furnaces, thereby avoiding misalignment between refractory prefabrication components.

[0005] In view of this, the present invention provides a refractory prefabricated component for an industrial furnace, comprising a refractory prefabricated component body, a positioning block fixedly connected to the top of the refractory prefabricated component body, a positioning groove provided at the bottom of the positioning block, reinforcing steel bars provided inside the refractory prefabricated component body, connecting ribs welded to the outer wall of the reinforcing steel bars, supporting ribs welded to the connection between the connecting ribs and the reinforcing steel bars, and positioning ribs welded to the top of the supporting ribs.

[0006] Based on the above structure, the interlocking of the positioning block and the positioning groove helps to improve the stability of the assembly of the fire-resistant precast component. The setting of two sets of reinforcing steel bars helps to improve the structural strength of the fire-resistant precast component. The setting of positioning ribs helps to improve the structural strength of the positioning block and prevent the positioning block from separating from the fire-resistant precast component.

[0007] Preferably, four sets of positioning blocks and positioning grooves are provided. The four sets of positioning blocks and four sets of positioning grooves are distributed in a circular shape at equal angles about the central axis of the refractory prefabricated body. In this embodiment, the refractory prefabricated body is prevented from falling off during assembly.

[0008] Preferably, the positioning block and the positioning groove are arc-shaped, and the positioning block and the positioning groove correspond one-to-one. In this embodiment, the interlocking of the positioning block and the positioning groove is beneficial to improving the stability of the assembly of the main body of the refractory prefabricated component.

[0009] Preferably, the reinforcing bars are ring-shaped and concentric. In this embodiment, by setting concentric reinforcing bars, comprehensive protection of the main body of the fire-resistant precast component is achieved, preventing cracking of the main body of the fire-resistant precast component.

[0010] Preferably, two sets of reinforcing bars are provided, and the two sets of reinforcing bars are parallel. In this embodiment, by providing two sets of reinforcing bars, it is beneficial to improve the structural strength of the main body of the fire-resistant precast component.

[0011] Preferably, the connecting bars are distributed at equal intervals along the outer wall of the reinforcing bar. In this embodiment, this is beneficial to improving the structural strength of the reinforcing bar and preventing deformation of the reinforcing bar.

[0012] Preferably, the central axis of the positioning rib coincides with the central axis of the positioning block. In this embodiment, this is beneficial to improving the structural strength of the positioning block and preventing the positioning block from separating from the main body of the fire-resistant prefabricated component.

[0013] The beneficial effects of this utility model are: The refractory precast component for industrial furnaces uses a positioning block and a positioning groove to fit together, which helps to improve the stability of the main body assembly of the refractory precast component. By setting two sets of reinforcing steel bars, the structural strength of the main body of the refractory precast component is improved. By setting positioning ribs, the structural strength of the positioning block is improved, and the separation of the positioning block from the main body of the refractory precast component is prevented.
