Kiln furniture (kiln car) used for firing of ceramic counter basin frame structures

Abstract

The invention relates to kiln furniture (a kiln car) used for the firing of ceramic counter basin frame structures. The kiln furniture (kiln car) includes a car frame, a plurality of uprights, beams and joists, wherein the uprights are arranged on the car frame, shelving through holes are formed in each upright, the shelving beams are arranged in the width direction of the car frame, each layer of the beams are horizontally erected on the shelving through holes in each pair of a front upright and a rear upright; two groups of the joists are arranged on each layer in the length direction of the car frame, each joist is erected on every two adjacent beams, one or two pairs of support plates are erected between each group of the joists, and a hollow cavity formed by each pair of the support plates and each group of the joists is used for loading one ceramic counter basin. The support plates are erected between each group of the joists, so that each pair of a front joist and a rear joist and each pair of a left support plate and a right support plate form a support frame with a support plane to support the periphery of a ceramic product, which can prevent the ceramic product from softening deformation during heating. The kiln furniture (kiln car) has the characteristics of low consumption of kiln materials per unit product, energy saving, consumption reduction, lower labor intensity of workers, higher superior product rate and the like.

Description

technical field [0001] The invention relates to a kiln furniture kiln car, in particular to a kiln furniture kiln car used for firing ceramic table basin frame structures. Background technique [0002] The structure, composition and characteristics of existing kiln cars used for loading ceramic products are as follows: [0003] 1. Each basin is composed of two SiC refractory boards and 6 refractory columns (or a single board); [0004] 2. The table basin kiln furniture combined with SiC refractory board can only be used alone, and cannot be used in various specifications of the table basin; [0005] 3. The kiln furniture is purchased from multiple points and two flat plates, which cannot guarantee the flatness. At the same time, the volume changes during the high-temperature firing process, resulting in the flatness of the basin product cannot be guaranteed; [0006] 4. After the SiC refractory board has been used for a period of time (about 2 months), the material is grad...

AI Technical Summary

Problems solved by technology

[0004] 2. The table basin kiln furniture combined with SiC refractory board can only be used alone, and cannot be used in various specifications of the table basin;

[0005] 3. The kiln furniture is purchased from multiple points and two flat plates, which cannot guarantee the flatness. At the same time, the volume changes during the high-temperature firing process, resulting in the flatness of the basin product cannot be guaranteed;

[0006] 4. After the SiC refractory board has been used for a period of time (about 2 months), the material is gradually oxidized, begins to expand in volume, begins to deform, the surface is loose, and in severe cases, slag appears, which affects the product grade of the basin;

[0007] 5. SiC kiln furniture is based on the third reason above, resulting in a short service life and increasing the firing cost of consumers;

[0008] 6. The table basin kiln furniture combined with the table basin and SiC refractory board has full contact between the surface and the surface. The thickness of the silicon carbide plate is 20mm, the area is large, the heat dissipation is slow, the heat absorption is large, and the energy consumption is high. Dark cracks appear in the basin;

[0009] 7. Basin kiln furniture products combined with SiC refractory boards have low loading density and high labor intensity
