Balance mesh belt is widely used in the sintering process of powder metallurgy, ceramics, glass, electronics, chemical industry and other industries, such as high temperature sintering of powder metallurgy iron-copper based parts, high temperature sintering of thick film circuits, thick film resistors and other electronic components, and sintering of ceramic products, etc.
Many customers have encountered a series of problems in the use of balance mesh belt. The following are some common problems and solutions.
1. Short life of mesh belt: material is very important
The high temperature environment in the sintering furnace and the weight and friction of the material can easily cause premature breakage or excessive wear of the mesh belt. If the mesh belt material is not properly selected or the tension is not adjusted during installation, it will accelerate the damage of the mesh belt.
Solution: Reasonable material selection is the key. According to the working temperature and process requirements of the sintering furnace, high temperature resistant, anti-oxidation and corrosion resistant materials should be selected, such as SUS310S, AISI314, nickel-based alloys, etc. During installation, a suitable tensioning device should be used and regularly checked and adjusted to ensure that the mesh belt tension is moderate. At the same time, the material should be evenly distributed to avoid local overload to reduce the pressure on the mesh belt.
2. Mesh belt deformation: mesh belt specification design should not be underestimated
Under the high temperature and tension of the sintering furnace, the mesh belt is prone to elongation and deformation. When the elongation is too large, the mesh belt and other parts in the furnace will have problems, resulting in deviation, jamming and other faults.
Solution: In the design stage, fully consider the thermal expansion coefficient and use environment of the mesh belt, and reasonably design the size and structure of the mesh belt to increase its rigidity and reduce the possibility of deformation.
3. Cleaning and maintenance: regular maintenance is important
During the sintering process, the material is easy to adhere to the mesh belt, and it will sinter and carbonize at high temperature to form hard lumps that are difficult to clean, which increases the difficulty of cleaning and maintenance cost of the mesh belt.
Solution: Develop a regular cleaning plan, clean up carbon deposits, dust and other impurities on the surface of the mesh belt in time, and keep the mesh belt clean. In daily maintenance, check the operation of the mesh belt and repair it in time if it is slightly damaged.
4. Mesh belt deviation: The mesh belt debugging process is very important
Uneven installation, uneven wear of guide rails, uneven material distribution, deformation of the mesh belt itself and other factors may cause the mesh belt to deviate during operation. Deviation will cause the edge of the mesh belt to rub against the furnace wall or guide rail, damage the mesh belt, and make the material unevenly distributed, affecting the sintering quality.
Solution: Strictly calibrate the position of the mesh belt and the guide rail during installation to ensure that they are parallel. Regularly check the sensitivity and reliability of the deviation correction device to ensure that it can play a role in time when the mesh belt deviates. Reasonably distribute materials during production to avoid deviation due to uneven force on the mesh belt caused by uneven material weight.
Although the sintering furnace mesh belt is small, it has a significant impact on production. Enterprises should pay attention to its management and maintenance, and extend the service life of the mesh belt and improve production efficiency and product quality through reasonable material selection, correct installation, and careful maintenance.
