- **Caution**: 
- **Caution**: 

### Q: What materials are recommended for ladle carriers in high-temperature applications?
**A**: For high-temperature molten metal handling, heat-resistant steel is recommended due to its ability to withstand thermal stress and oxidation, while carbon and alloy steels are suitable for standard temperature operations with proper maintenance.

### Q: How does the ladle carrier ensure safe lifting of molten metal?
**A**: The ladle carrier features a robust main beam with trunnion hooks that securely engage the ladle, reinforced plates for structural integrity, and mounting brackets that distribute weight evenly, preventing spills during lifting and sealing operations.

### Q: What maintenance is required for ladle carriers in basic metal manufacturing?
**A**: Regular inspection for wear, cracks, or deformation in the main beam and hooks, lubrication of moving parts, and checking reinforcement plates for integrity are essential. Material-specific maintenance includes monitoring for thermal fatigue in heat-resistant steel components.
