Understanding the precautions helps ensure better use of the high-temperature sintering furnace and reduces the likelihood of errors. Baoji Dingsheng Vacuum Thermal Technology Co., Ltd. summarizes the following key points:
- Strict Temperature Control: The operating temperature must be strictly limited to 1120–1150 °C; exceeding this range will significantly shorten the life of the mesh belt.
- Mesh Belt Failure: The main forms of failure include:
- Deformation and elongation: exceeding the allowable elongation of 10–20%.
- Material degradation: oxidation, carburization, and fatigue reduce the cross-section of the wires, causing fatigue cracks or even breakage.
- The mesh belt has a relatively short service life (approximately 6–9 months) and is costly to replace.
- Furnace Door Management: The furnace door should always remain open, leaving a gap just sufficient for the green compact to pass through. This type of furnace requires a substantial protective atmosphere.
