Sintering furnace mesh belts are widely used in sintering processes in industries such as powder metallurgy, ceramics, glass, electronics, and chemicals. These applications include high-temperature sintering of powder metallurgy iron-copper components, high-temperature sintering of electronic components such as thick-film circuits and resistors, and sintering of ceramic products.
Many customers encounter a variety of problems with their sintering furnace mesh belts. The following are some common issues and solutions.
Sintering Furnace Mesh Belts
1. Short Mesh Belt Life: Material Matters
The high temperature environment within the sintering furnace, as well as the weight and friction of the materials, can easily lead to premature breakage or excessive wear of the mesh belt. Improper mesh belt material selection or improperly adjusted tension during installation can accelerate belt damage.
Solution: Appropriate material selection is crucial. Choose materials that are resistant to high temperatures, oxidation, and corrosion, such as SUS310S, AISI314, and nickel-based alloys, based on the sintering furnace's operating temperature and process requirements. During installation, use a suitable tensioning device and regularly check and adjust the belt to ensure proper tension. At the same time, ensure even material distribution and avoid local overload to reduce stress on the mesh belt.
2. Mesh Belt Deformation: Mesh belt specifications and design are crucial.
Under the high temperatures and tensile forces of the sintering furnace, the mesh belt is prone to elongation and deformation. Excessive elongation can cause problems with the mesh belt's coordination with other components within the furnace, leading to problems such as deviation and jamming.
Solution: During the design phase, fully consider the mesh belt's thermal expansion coefficient and operating environment, and rationally design the mesh belt's dimensions and structure to increase its rigidity and minimize deformation.
3. Cleaning and Maintenance: Regular maintenance is crucial.
During the sintering process, material easily adheres to the mesh belt and, at high temperatures, sinters and carbonizes, forming hard lumps that are difficult to clean. This increases cleaning difficulty and maintenance costs.
Solution: Establish a regular cleaning schedule to promptly remove carbon deposits, dust, and other impurities from the mesh belt surface to maintain a clean mesh belt. During routine maintenance, inspect the mesh belt's operating condition and promptly repair any minor damage.
Mesh Belt Deviation: The Mesh Belt Adjustment Process is Critical
Uneven installation, uneven guide rail wear, uneven material distribution, and deformation of the mesh belt can all cause the mesh belt to deviate during operation. Deviation can cause the mesh belt edge to rub against the furnace wall or guide rails, damaging the mesh belt. It can also lead to uneven material distribution and affect sintering quality.
Solution: During installation, strictly calibrate the mesh belt and guide rails to ensure they are parallel. Regularly check the sensitivity and reliability of the deviation correction device to ensure it is fully operational when the mesh belt deviates. Ensure proper material distribution during production to avoid uneven belt force and deviation caused by uneven material weight.
Although the sintering furnace mesh belt is small, it has a significant impact on production. Companies should prioritize its management and maintenance. Through appropriate material selection, proper installation, and meticulous maintenance, they can extend the mesh belt's service life, improve production efficiency, and enhance product quality.
