**Precautions for the Use of Cast Iron Plates**
Cast iron plates are essential tools in various industrial and mechanical applications. To ensure their longevity and maintain precision, proper handling, storage, and maintenance are crucial. Below are detailed guidelines to follow when using and maintaining cast iron plates.
**Installation and Initial Setup**
Before installation, it is important to first assemble and test the cast iron plate to avoid damage to its working surface. Proper alignment and calibration during installation are vital to prevent structural issues or inaccuracies that could affect performance.
**Environmental Conditions**
Cast iron plates should be used in a controlled environment. The recommended operating conditions include:
- Altitude below 1000 meters
- Maximum temperature: +40°C
- Minimum temperature: -5°C
- Maximum daily temperature difference: 15K
- Relative humidity (at 20°C): up to 95%
- Installation location: indoor only
Avoid placing the cast iron plate in areas with extreme temperatures or high humidity, as these conditions can accelerate corrosion and reduce accuracy.
**Load Capacity and Usage**
Ensure that the weight of the workpiece does not exceed the rated load capacity of the cast iron plate. Overloading may lead to deformation, reduced accuracy, or even structural damage. Always handle the workpiece gently to avoid scratches, bumps, or other surface damage.
**Cleaning and Rust Prevention**
After use, clean the working surface thoroughly and apply a thin layer of rust-preventive oil. Cover the plate with anti-rust paper and store it in a dry, ventilated area. Avoid storing it near heat sources, corrosive gases, or liquids, which can cause rapid deterioration.
**Maintenance and Storage**
To prevent deformation, always use four evenly spaced lifting wires when moving the cast iron plate. Ensure that support points are properly padded and leveled to distribute weight evenly. When installed, adjust the support points using shims or jacks to achieve optimal precision.
Regular inspections are recommended according to national standards, typically every 6–12 months depending on usage frequency. If the plate is not in use for an extended period, implement proper rust prevention measures such as sealing with desiccants or applying anti-rust oil. Long-term storage should involve wrapping the plate in neutral paraffin paper or sodium formate paper to protect against moisture.
**Rust Protection Methods**
There are several effective methods for rust protection:
1. **Anti-rust Lubricating Oil**: Applied at room temperature, this oil provides both lubrication and corrosion resistance. It is ideal for general mechanical equipment and is widely used due to its effectiveness and ease of application.
2. **Replacement-Type Anti-rust Oil**: This type of oil removes moisture from metal surfaces, preventing fingerprint rust caused by sweat and oils. It is particularly useful for measuring tools and welding platforms.
3. **Solvent-Diluted Anti-rust Oil**: Contains volatile solvents that evaporate after application, leaving behind a protective film. Suitable for large devices and outdoor use, but requires fire safety precautions due to flammable components.
4. **Rust-Preventive Water**: A cost-effective and environmentally friendly option for short-term protection. It is easy to apply and remove, making it ideal for temporary storage.
5. **Gas Phase Anti-rust Paper**: Used in sealed environments to provide long-term protection by releasing vapor-phase inhibitors that prevent corrosion.
**Workshop and Warehouse Management**
Keep the workshop clean and free from excessive dust. During summer, dehumidify the warehouse to control humidity levels. Be cautious of low-temperature frost, which can also cause corrosion. After each day’s use, wipe down all moving parts and exposed metal surfaces with anti-rust oil to maintain their condition.
By following these guidelines, you can significantly extend the service life of your cast iron plate and ensure consistent performance over time. Regular maintenance and proper storage are key to preserving its precision and durability.
