# Industrial Specification: Molten Metal Transfer Car

## 1. Technical Definition
Rail-mounted vehicle for transporting molten metal between furnace and casting stations

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.5 m/s travel speed, 1400-1600°C molten metal temperature, 10-50 metric tons payload capacity**. Failure boundary: **Track deformation exceeding 15 mm/m linear deviation, refractory lining erosion beyond 40% thickness loss, wheel bearing temperature exceeding 120°C**, Mechanism: **Thermal expansion mismatch between steel rails (α=12×10⁻⁶/°C) and concrete foundation (α=10×10⁻⁶/°C) causing track buckling, refractory spalling due to thermal shock exceeding 200°C/min gradient**.

- **Caution**: 

### Q: What safety features does the molten metal transfer car include?
**A**: The transfer car includes safety guard rails, emergency stop systems, thermal protection for components, and refractory lining to contain molten metal safely during transport.

### Q: How is the molten metal ladle tilted during pouring operations?
**A**: A hydraulic tilting mechanism with precision cylinders allows controlled pouring at adjustable angles, typically up to 90-120 degrees, with smooth operation to prevent metal splashing.

### Q: What maintenance is required for the rail-mounted transfer system?
**A**: Regular maintenance includes rail wheel inspection, hydraulic system checks, refractory lining replacement as needed, electrical system testing, and structural integrity verification of the steel chassis.
