Analysis of Fault Causes of Main Shaft Tile Sintering
1 Introduction
Tile sintering is a form of heat-treatment of a material, usually a refractory material, to give it a certain strength, or to obtain a combination of high strength and conductivity. Tile sintering is often used to make a material hard enough to be machined or used as a component of a larger assembly. Commonly used in the production of refractory metals, such as titanium, ceramics and non-metallic composites, tile sintering has become an important manufacturing process in various industrial processes. The main shaft tile sintering is one kind of tile sintering, it uses the tile sintering technology to make the refractory material close to a stable state by using its own thermal expansion coefficient, thereby making the materials workpiece strength and operating temperature have a good effect.
2 Main Shaft Tile Sintering Fault Causes Analysis
2.1 Poor Sintering Effect
The sintering of the main shaft tile mainly occurs on two occasions: First, when the temperature is too low or the heating time is too short, and second, when the powder composition of the raw material is not uniform, so the melting point of the raw material is too low. In these two circumstances, the tile sintering effect is poor, that is, the gap in the sintered material is large and there is no good tightness. At this time, to avoid this situation, it is necessary to increase the temperature and the time for sintering the main shaft tile. Meanwhile, the powder used for sintering should also be carefully analyzed to make sure that it has a uniform composition.
2.2 Uneven Sintering
Uneven sintering occurs when the sintering temperature of the main shaft tile is too high or the heating time is too long. In this situation, the raw materials in the tile will be oxidized, and their bond will be loosened. As a result, the sintering effect of the tile will be uneven, and the material strength and performance will be affected. To avoid this situation, the temperature and time for sintering the main shaft tile must be strictly controlled.
2.3 Fragile Tile
Fragile tile occurs when the sintering temperature of the main shaft tile is too low, or the raw materials used for sintering have a poor quality. When the sintering temperature is too low, the bond between particles will be too loose, causing the tile to become fragile and easy to break. To improve this, the sintering temperature should be raised and the quality of the raw materials should be strictly checked.
3 Conclusion
The sintering of the main shaft tile is an important process in refractory metal and ceramic manufacturing. When the temperature and time of sintering are not correctly controlled, the sintering effect will be poor, and the tile will become fragile and uneven. Therefore, it is important to set accurate parameters for the sintering of the main shaft tile, and to pay attention to the selection of raw materials to ensure the quality of the manufactured product.
