During quench, there are several safety precautions that need to be considered:
1. Avoid skin contact with quench oils: Quench oils used in the process can be very hot, exceeding 100°C. Skin contact with these oils can cause burns. It is important to use gloves and protective clothing to prevent any splashes or direct contact with the oils.
2. Prevent contamination of quenching oil: When not in use, the quench tanks should be covered to avoid any contamination of the oil by water. Water can cause the oil to lose its properties and effectiveness.
3. Be cautious with oil as a quenchant: It is important to exercise caution when using oil as a quenchant, as it has the potential to catch fire. The hot temperature of the oil can also cause burns if there are any splashes or skin contact.
4. Avoid operating the furnace when vibrating: Operating the furnace while it is vibrating can be dangerous. This can potentially lead to accidents or damage to the furnace and its components.
5. Handle thermocouples carefully: When the furnace is operating at high temperatures, it is important not to suddenly pull out the thermocouple. This can cause the jacket to burst, leading to potential hazards.
6. Be aware of volatile and corrosive gases: When heating materials that contain fats or metallic substances, volatile and corrosive gases can be released. These gases can affect the surface of the heating element and cause damage, shortening its lifespan. Proper ventilation and safety measures should be in place to prevent any harm.
7. Follow proper procedures for oil drainage and recharge: Instead of relying solely on the sight glass, it is recommended to drain the oil completely and recharge it with the correct measured amount. This ensures that the oil is properly maintained and minimizes the risk of any issues.
8. Maintain proper water chemistry: Cooling water used in the process should have the correct chemistry to prevent mineral deposits and scale (rust) buildup. Regular testing and adding chemicals as required are important to ensure the cooling water is effective. Water filter bags can also be used to filter out any deposits and should be changed monthly.
9. Follow company rules and use common sense: Health and safety are everyone's responsibility. It is important to be aware of the dangers and take necessary steps to avoid incidents. Following company rules and using common sense can go a long way in preventing injuries.
10. Special precautions for vacuum oil quenching of high alloy die steel: When working with high alloy die steel materials, such as 4Cr5MoSiV and Cr12MoV, special care should be taken. These materials have high heating temperatures, and the quenching oil mist can have high concentration and volatilization. It is crucial to prevent the flash point or ignition point of the oil from being reached during the release of the oil. This can be done by ensuring the oil cooling time is strictly followed according to the process and not releasing the oil prematurely. Additionally, proper ventilation and release of air from the furnace after quenching can prevent the ignition of oil and gas, reducing the risk of explosion accidents when opening the furnace door.
