Refractory kiln furniture is a critical component in high-temperature industries. Common materials include silicon carbide (SiC), alumina, mullite, and cordierite, each selected for properties like heat resistance, corrosion resistance, low thermal expansion, or lightweight design. Key types include kiln posts (vertical support), shelves (horizontal load-bearing), saggars (contamination isolation), pusher plates (product transport), and setter plates (direct workpiece holding). These components are widely used in sintering ceramics, glass, and electronics, protecting products from extreme heat while enhancing energy efficiency through optimized kiln design, ensuring both process reliability and product quality.
Plain Props for kiln furniture possess the following remarkable product characteristics:
1. High Temperature Resistance: Manufactured from specialized high-temperature materials like cordierite-mullite, mullite, corundum, and silicon carbide, they can effortlessly withstand the high-temperature environment in the kiln, which often reaches thousands of degrees Celsius. Even during long-term continuous operation, they will not soften or melt, maintaining structural stability at all times and ensuring the smooth progress of the firing process.
2. High Strength: They exhibit excellent mechanical strength. Under the heavy load of refractory plates and numerous items to be fired, they can still stand upright firmly without easily bending or breaking. They reliably support the firing space, providing a solid guarantee for safe production.
3. Precise Dimensions: Thanks to rigorous manufacturing processes, they have accurate height, diameter and other dimensional specifications. They can not only perfectly match the internal structures of various kilns to meet diverse layout requirements but also ensure the horizontal placement of refractory plates, enabling even heat distribution and preventing uneven firing caused by dimensional deviations.
4. Chemical Stability: In the face of the complex chemical atmosphere inside the kiln, including various corrosive gases and reaction products at high temperature, ordinary pillars, by virtue of their good chemical stability, effectively resist erosion, ensuring that their own performance is not damaged and prolonging their service life.
5. Thermal Stability: During the frequent heating and cooling cycles of the kiln, when the temperature changes drastically, ordinary pillars can quickly adapt to thermal expansion and contraction. They will not develop cracks or break due to the accumulation of thermal stress, maintaining good thermal cycling performance.
