1. Body Sintering

• • In ceramic tile manufacturing, the push plate kiln is first used for sintering the tile body. The raw materials for ceramic tiles, which typically include clay, feldspar, quartz, and other additives, are formed into tile shapes and then placed on the push plates. As the push plates move through the heating zone of the kiln, the tile bodies are gradually heated. In the initial stages, moisture is removed from the tile bodies at relatively low temperatures. Then, as the temperature rises, the chemical reactions start to occur. The clay minerals undergo dehydration and recrystallization, while the feldspar and quartz melt and bind the other components together. The precise temperature control in the push plate kiln ensures that the tile bodies are sintered uniformly, resulting in tiles with consistent strength and density. For example, in the production of porcelain tiles, which are known for their high strength and low water absorption, the sintering temperature in the push plate kiln is carefully maintained between 1200 - 1300°C.

2. Glaze Firing

• • After the body sintering, the tiles are often glazed to enhance their appearance and functionality. The push plate kiln is again used for glaze firing. Glazes are applied to the surface of the pre - sintered tile bodies, and then the tiles are re - introduced into the kiln. The glaze firing process requires a different temperature profile compared to body sintering. The temperature is usually raised to a point where the glaze melts and spreads evenly over the tile surface, forming a smooth and glossy finish. The multi - zone temperature control of the push plate kiln allows for a gentle heating and cooling cycle, which is essential for preventing the formation of cracks or bubbles in the glaze. Different types of glazes, such as glossy, matte, or textured glazes, require specific temperature and time combinations, and the push plate kiln can be easily adjusted to meet these requirements. For example, a glossy glaze may require a peak temperature of around 1000 - 1100°C, while a matte glaze may need a slightly lower temperature and a different cooling rate.

3. Specialty Tile Production

• • In the production of specialty tiles, such as anti - slip tiles or tiles with unique decorative effects, the push plate kiln also plays a crucial role. Anti - slip tiles often require a specific surface texture, which can be achieved by controlling the firing process. The push plate kiln can be used to create a rough surface on the tile body during sintering or to apply a special glaze that provides the anti - slip property. For tiles with decorative effects like in - lay patterns or metallic lusters, the kiln's precise temperature control enables the proper fusion and adhesion of different materials. For instance, tiles with in - lay patterns may require multiple firing steps in the push plate kiln to ensure that the in - lay materials are firmly bonded to the tile body and that the overall appearance is aesthetically pleasing.

1. Bisque Firing

• • Ceramic tableware production begins with bisque firing. The unfired ceramic tableware pieces, made from clay mixtures, are placed on the push plates and sent through the push plate kiln. During bisque firing, the temperature is gradually increased to around 900 - 1000°C. At this temperature, the clay undergoes a series of physical and chemical changes. The water in the clay is completely removed, and the clay particles start to bond together, giving the tableware pieces their initial strength. The bisque - fired tableware is then ready for further processing, such as glazing or decoration. The continuous operation of the push plate kiln allows for a large number of tableware pieces to be bisque - fired in a short time, meeting the high - volume production demands of the tableware industry.

2. Glaze Firing and Decoration Firing

• • After bisque firing, the tableware pieces are glazed. The glaze not only provides a smooth and attractive surface but also makes the tableware more resistant to stains and scratches. The push plate kiln is used for glaze firing, where the temperature is adjusted to melt the glaze and ensure a uniform coating on the tableware. Different types of glazes, such as transparent glazes, colored glazes, or underglaze decorations, require specific firing conditions. For example, underglaze decorations are applied to the bisque - fired surface, and then a transparent glaze is applied on top. The push plate kiln is used to fire the tableware at a temperature that allows the underglaze colors to develop and the transparent glaze to melt and seal the decoration. In some cases, additional firing steps may be required for overglaze decorations, such as applying gold or platinum luster. The push plate kiln's ability to provide precise temperature control and a consistent firing environment is essential for achieving high - quality and durable ceramic tableware.

3. Quality Control and Batch Production

• • In ceramic tableware production, quality control is of utmost importance. The push plate kiln's precise temperature control and automated operation contribute to consistent product quality. Since the kiln can maintain the same firing conditions for each batch of tableware, the likelihood of defects, such as uneven glazing or warping, is significantly reduced. This is especially important for large - scale tableware manufacturers who need to produce thousands of identical pieces for commercial use. The continuous operation of the push plate kiln also allows for efficient batch production. New batches of tableware can be loaded into the kiln as soon as the previous batch has been unloaded, maximizing production output while maintaining quality standards.

1. Ceramic for Electronics

• • In the production of ceramics for electronics, such as ceramic capacitors, resistors, and substrates, the push plate kiln is indispensable. Ceramic capacitors, for example, are made from ceramic materials with specific dielectric properties. The push plate kiln is used to sinter the ceramic powders into the desired capacitor shapes. The precise temperature control is crucial because the dielectric properties of the ceramic are highly sensitive to the firing temperature. A small deviation in temperature can lead to significant changes in the capacitance value of the capacitor. The push plate kiln allows for a controlled heating and cooling process, ensuring that the ceramic capacitors have consistent and accurate electrical properties. Similarly, for ceramic substrates used in printed circuit boards, the push plate kiln is used to sinter the ceramic materials to a high density, providing a stable and electrically insulating base for the electronic components.

2. Ceramic for Aerospace and Defense

• • Advanced ceramics used in aerospace and defense applications, such as ceramic matrix composites and thermal barrier coatings, require extremely precise firing conditions. Ceramic matrix composites are made by embedding ceramic fibers in a ceramic matrix. The push plate kiln is used to sinter the composite materials at high temperatures, typically above 1500°C. The high - temperature resistance and precise temperature control of the push plate kiln enable the proper bonding of the fibers and the matrix, resulting in materials with high strength, low weight, and excellent thermal resistance. Thermal barrier coatings, which are applied to the surfaces of aircraft engine components to protect them from high temperatures, are also processed using push plate kilns. The kiln is used to sinter the coating materials onto the substrate, ensuring a strong adhesion and the desired thermal insulation properties.

3. Bioceramics Production

• • Bioceramics, which are used in medical applications such as dental implants and bone grafts, also rely on the push plate kiln for production. These ceramics need to have specific physical and chemical properties to be biocompatible. The push plate kiln is used to sinter the bioceramic materials, such as hydroxyapatite - based ceramics, at temperatures that promote the formation of the correct crystal structure. The precise temperature control ensures that the bioceramics have the right porosity and surface characteristics for cell attachment and tissue integration. For example, in the production of dental implants, the push plate kiln is used to sinter the ceramic implant bodies to a high density, while maintaining a surface roughness that is conducive to the growth of surrounding tissues.
