Description

Technical Field

[0001] This utility model relates to a corrugated, flexurally resistant composite heat-bearing plate. Background Technology

[0002] Ceramic firing plates often need to be used in layers in kilns. When multiple layers of firing plates are used to support the products, they move in the furnace under the action of the kiln's propulsion device. During the acceleration and deceleration of the movement, relative sliding can easily occur between the firing plates.

[0003] An existing patent discloses a ceramic firing plate (patent number CN201520128185.4). Through the setting of upper support feet, lower support feet and locking parts, the ceramic firing plates can be locked and fixed when aligned and stacked, ensuring safe placement and facilitating the design of automated unloading and stacking production lines. However, those skilled in the art know that this patent still has the following problems: After two adjacent firing plates are stacked, the upper and lower support feet are fixed by the locking parts. However, due to the small contact area of ​​the locking parts, although they can lock and fix the plates when placed normally, and the upper and lower support feet do not have the characteristic of mutual limiting, misalignment will still occur during the relative movement between the firing plates, resulting in the entire stack of firing plates tilting or even collapsing. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a corrugated, flexurally resistant composite heat-bearing plate.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A corrugated, flexurally resistant composite firing plate includes a firing plate body, an upper support base integrally formed on the upper surface corner of the firing plate body, and a lower support foot integrally formed on the lower surface corner of the firing plate body. The upper support base is set at a right angle and has stepped grooves at both ends. The lower support foot is set at a right angle and has stepped steps integrally formed at both ends. The depth of the stepped groove is the same as the height of the stepped step.

[0007] Preferably, the substrate includes a bottom layer, a silicon carbide layer formed on the upper surface of the bottom plate, a lower oxide layer formed on the lower surface of the bottom layer, and an upper oxide layer formed on the surface of the silicon carbide layer.

[0008] Furthermore, the bottom layer is a mullite bottom layer.

[0009] Furthermore, the upper surface of the silicon carbide layer has several equally spaced ventilation slots.

[0010] Furthermore, several equally spaced ventilation slots form ripples on the upper surface of the silicon carbide layer.

[0011] Furthermore, both the lower and upper oxide layers are zirconium oxide coatings.

[0012] The beneficial effects of this utility model are as follows: When two firing plates are stacked, the stepped groove and stepped steps are used to complete the stacking installation. In addition, after the two firing plates are stacked and installed, the stepped groove and stepped steps are used to lock and restrict each other to prevent the two firing plates from shifting. This improves the stability of the firing plates when they need to be moved later, avoids misalignment and sliding between the firing plates, and at the same time reduces the possibility of tilting or even collapse between multiple firing plates, thus avoiding any impact on the work.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0018] Example

[0019] like Figure 1-4 As shown, a corrugated, flexurally resistant composite firing plate includes a firing plate body 1, an upper support seat 2 integrally formed on the upper surface corner of the firing plate body 1, and a lower support foot 3 integrally formed on the lower surface corner of the firing plate body 1. The upper support seat 2 is set at a right angle and has stepped grooves 21 at both ends. The lower support foot 3 is set at a right angle and has stepped steps 31 integrally formed at both ends. The depth of the stepped groove 21 is the same as the height of the stepped step 31.

[0020] Specifically, when two firing plates are stacked, a stepped groove and a stepped step are used to complete the stacking installation. In addition, after the two firing plates are stacked and installed, the stepped groove and the stepped step are used to lock and restrict each other to prevent the two firing plates from shifting. This improves the stability of the firing plates when they need to be moved later, avoids misalignment and sliding between the firing plates, and at the same time reduces the possibility of tilting or even collapse between multiple firing plates, so as to avoid affecting the work.

[0021] It should be further explained that after the two firing plates are stacked and installed, the stepped grooves and steps create a ventilation space between the two firing plates, which makes the small-volume high-temperature resistant products inside more evenly fired.

[0022] The firing plate body 1 includes a bottom layer 11, a silicon carbide layer 12 formed on the upper surface of the bottom plate 11, a lower oxide layer 13 formed on the lower surface of the bottom layer 11, and an upper oxide layer 14 formed on the surface of the silicon carbide layer 12.

[0023] In this embodiment, the bottom layer 11 is a mullite bottom layer, specifically, it can serve as the main load-bearing plate of the entire fire-bearing plate body 1.

[0024] The upper surface of the silicon carbide layer 12 has several equally spaced ventilation slots 121, which can improve the ventilation capacity of the sintering plate body 1, so that hot air can be evenly distributed through the ventilation slots 121, thereby improving the sintering quality of the product.

[0025] It should be further explained that the equidistant ventilation slots 121 form ripples on the upper surface of the silicon carbide layer 12, which specifically improves the bending resistance of the entire bearing plate body 1.

[0026] In this embodiment, both the lower oxide layer 13 and the upper oxide layer 14 are zirconium oxide coatings.

[0027] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
