Precautions for Silicon Carbide Kiln Shelves
- Installation: Silicon carbide plates are tough. Avoid collision and falling during transportation and installation to prevent cracks or damage on the plate surface, which will affect its performance and service life.
- Offer expansion space: Silicon carbide plates will undergo some thermal expansion at high temperatures. Generally, appropriate gaps should be left between plates and between plates and kiln walls to prevent extrusion deformation or damage to the kiln structure by thermal expansion.
- Temperature control: Monitor the kiln temperature with precision so that it never goes beyond the working temperature of the silicon carbide plate.
- Prevent sudden heating and cooling: When heating and cooling the kiln, the speed must be controlled to avoid sudden changes in temperature. We recommend adjusting the heating and cooling speeds within a reasonable range. The corresponding values can be calculated based on the properties of the silicon carbide plate and the actual kiln conditions.
- Uniform placement: Place the materials uniformly on the silicon carbide plate to avoid heavy local loads. Uniform loads will cause uniform pressure on the silicon carbide plate, which will easily cause deformation or damage of the plate and affect its service life and normal operation of the kiln.
The best plates are made of high-quality heat-resistant materials (such as silicon carbide) that have excellent thermal shock resistance, low thermal expansion, and good load-bearing capacity. They should also have a smooth surface, even heat distribution, and be durable enough to withstand repeated firings.
The thickness of the silicon carbide kiln shelves is usually between 3mm and 20mm. The thickness depends on the type of kiln, the weight of the fired items, and the specific requirements of the firing process. Silicon carbide kiln shelves with higher thickness are usually used for heavier loads or high-temperature firing.
Common refractory materials include silicon carbide, alumina, cordierite mullite, corundum, graphite, etc. Among them, silicon carbide has high hardness, high thermal conductivity and good thermal shock resistance, can maintain good strength and stability at high temperatures, and has good oxidation resistance.
We usually apply a layer of aluminum oxide coating to the silicon carbide plate according to different usage and requirements of customers. The purpose of this is to prevent porcelain from sticking at high temperatures and keep the product clean and tidy during firing.
